MOWER RACING SERIES
2011 RACING SEASON
Rules that differ from the 2011 rulebook have
been highlighted in bold faced
red print.
Additional rule changes may be implemented as
needed. Please monitor the National websitewww.

BTMRA forum for changes
The
American Racing Mower Association (ARMA) /
Bama-Tenn Mower Racing Assn. (BTMRA) is an organization designed for lawn mower racers by lawn
mower racers. This sport provides racers, their families and friends the opportunity to get involved with
compe:censored:ive racing that is affordable.
This rulebook provides the standards that regulate the operations within ARMA/BTMRA. Maintaining safe, compe:censored:ive
racing is the primary purpose of this do:censored:ent and with the cooperation of all members, we can collectively
keep this sport as it was intended, FUN.
A lot of time, money, and energy have been spent on mower fabrication, engine building, and traveling to and
from race venues. Keep that in mind when racing and race clean and safe. Although mishaps will happen from
time to time on the track, lets look out for each other and keep ourselves and our mowers in the same
conditions when we started the race as when we leave.
General Regulations
1. On Track Regulations
Any deliberate actions to cir:censored:vent the safety features of a mower at either a Local Chapter or National Points
Series race will result in sanctions for the driver. These sanctions will include a minimum of the following:
Total loss of points for said event
Suspension from 2 race events immediately following the incident
Based upon the severity of the incident sanctions may be increased at the discretion of the BTMRA staff or the ARMA National Board of Directors (dependent upon
where the incident occurred).
Actions to deliberately violate the rules for any mower class will result in the same
sanctions found above.
No alcoholic beverages or illegal drugs are allowed within the controlled area of the racing activity,
including the pit area.
a. Any person who is actively participating in a race event (at any level) who has consumed alcoholic
beverages, illegal drugs, or controlled substances that is mind and/or motor skills altering may not
participate in any capacity.
b. Completing a safe pass is the responsibility of the overtaking driver. No bumping will be tolerated.
This means if you initiate a pass and during execution you realize you cannot complete the pass in a safe
manner then it is up to the overtaking driver to return to a safe position on the track while avoiding
contact with other racers. You will gain more respect by taking yourself out then placing the other racers
in an unsafe situation causing personal injury and mower damage.
c. If you are being overtaken by another racer and it is clear that they are faster make room for the
overtaking racer and let them pass.
d. Multiple mower blocking is not permitted.
e. The racer that causes an incident will restart the race at the end of the field. This will be determined
by the track officials.
f. Flags will be used to communicate to the racers the following on track conditions:
Green: The race/practice is underway when displayed.
Yellow: CAUTION, DANGER. No passing on the entire track and the drivers will form a single line at a
safe pace speed and close up to the leader and follow the starters directions.
Yellow & White: The field is not bunched up for restart. If this is displayed, close it up.
Red: Stop all racing action immediately and shut off your engine. This flag is used in emergency
situations where personal injury has occurred or the track is blocked.
Blue with Yellow Stripe: Faster mowers are approaching, drivers should yield track position to race
leaders.Black: This for driver or equipment infractions. The driver must safely exit the track and consult with the
Chief Steward. A furled black flag is a warning to a driver to clean up his/her act or receive the full
black flag indicating he/she needs to exit the track.
White: One lap to go. Crossed white and green indicates race is halfway complete.
Checkered: End of race or practice session. Winner may choose to make a victory lap with the checkered
flag. The remaining drivers will complete the lap and safely exit the track to the pit area.
g. Driver must keep both hands on the steering wheel, except to momentarily operate other controls.
Drivers body may not be intentionally positioned out of the mower seat onto or over the mower fender.
h. If you leave the course during the race re-enter the track as close as possible to the exiting point.
Exiting the course and reentering in order to gain position will result in the driver being placed at the
rear of the field.
i. If the mower stalls move the mower off the track to a safe place at least 10 feet off course.
Mowers
may not be moved to the infield. j. Anyone dismounting a mower in anger will be removed immediately from that race. Anyone
touching another racer or track official in anger will be removed from the property where the race is
being held.
k. Unsafe off track driving will not be tolerated.
l. Drivers must attend all drivers meetings. If an unforeseen cir:censored:stance forces a driver to miss the
meeting they shall begin at the rear of the field after meeting with the Chief Steward for a briefing on the
days racing information.
m. Starting positions will be determined by random draw for a rolling start.
2. Pit Area and Track Regulations
a. Mower pit speed is 5 MPH maximum.
b. Long pants, closed shoes and shirts are required in the track area.
c. Refueling: Driver must dismount and engine must be shut off when fuel is added. A fire extinguisher
(Liquid Fire Rated) must be in the hands of a crew member any time fuel is added to a hot machine.
d. Mower must be completely stopped before driver dismounts.
e. Track crews are under the direction of the Track Steward at all times.
f. The driver is responsible for the conduct of his/her guests and crew, even while on the track.
g. Only authorized personnel and drivers shall enter the racing course during racing activity. All
individuals entering the pit area, including crew members and guests, must sign a release discharging
ARMA from liability. All individuals entering the track area must have a wrist band.
h. No pets are allowed on the racing course.
i. ARMA reserves the right to limit pit space. Campers and RVs may be permitted on race day only if
space permits.
j. No vehicles other than racing mowers and official vehicles such as tow mowers shall be on or near the
track.

IMPORTANT SAFETY NOTE
There may be no alterations to a stock flywheel. This is to include removing the magnets and/or
removing metal from the flywheel in various locations. Altered flywheels are not tested under any
standards for safety and may not withstand high rpms. Billet flywheels are required in any
ungoverned class. v. All steering and wheel retention fasteners must terminate with locking nuts, castellated nuts with
cotter pins, washers with new cotter pins, shaft locks, or locking bolts. Cotter pins, E-rings and C-rings

commercially available race fuel- maximum 114
octane. The addition of nitrous oxide, rocket fuel, alcohol or other oxidizers
by a racer is not
permitted. No combustion enhancing substances may be added to the crankcase oil or air cleaner
assembly. Any attempt to cir:censored:vent this rule will result in disqualification from the event. No electric
fuel pumps.
z. All engines must be naturally aspirated. Blowers, turbochargers, and water injection systems are not
allowed.
aa. Tires must be lawn tractor tires in all classes except Pro-X and Super Modified.
bb. Subs:censored:uted steering wheels are permitted. They may not be mounted offset unless originally
mounted offset. Steering wheel consists of a 360 degree circular device. This wheel may not be
pegged or have steering devices attached to them. Hand throttle and brake controls are permitted.
cc. All positively charged terminals must be insulated with a cover or heavy tape. Battery must be well
secured on the mower.
Any battery mounted outside of the frame must have the sides encased in
steel a minimum of 1/8 thick 2/3 of the way up the sides of the battery and must include an
additional hold down support. dd. All mowers must be safe and complete with all parts and panels in places with no missing fasteners.
Machines that have been involved in a on-track incident resulting in removal of body parts will only be
allowed back on the track after the mower has been inspected to determine if its return would present a
safety issue.
ee. All exposed sprockets, chains, rotating shafts and pulleys must be fitted with metal guards 1/8 inch
thick minimum deflecting a broken chain downward and preventing entanglement with mower parts.
ff. Mowers must be free of sharp edges, projections and protrusions.
gg. A rear bumper is highly recommended and should be no wider than the rear tire width, fabricated
from either 1 or Ύouter diameter tubing with radius bends and installed a maximum of 2 from closest
surface of the rear tire. Recommended height of no higher than 8. The bumper should be centered on
the rear axle. The intent of the bumper is to prevent mowers from climbing the rear tires and making
contact with a driver. No other bumpers are permitted, even those offered as factory options.
hh. Seats must be present and of lawn mower origin except Super Modified classes. Seat is defined as
being a separately attached device on which the driver will place his body during racing compe:censored:ion.
They should be securely mounted to the mower, on the center of the frame. Seats may be adjusted more
towards the front or rear of the mower along the center line to help achieve better weight balance for
handling.
ii. The lowest portion of the seat pan should not be mounted lower than the top of the rear tires except in
Super Modified classes.
jj. Sheet metal should be as delivered from the factory with the following exceptions:
Subs:censored:utions:
Where original factory sheet metal is not available or is damaged in a way that renders it unsafe
or unusable sheet metal from another similar model mower that would otherwise be eligible to
race may be used.
Replacement sheet metal must fit properly and be as close in shape to the factory panel as
possible.
Subs:censored:ute sheet metal should be attached to the frame in as close to the original position as
possible.
All panels must be securely fastened so as not to create a safety hazard.
Subs:censored:uted panels must be modified to fit properly and safely.
Minimal under hood mounting brackets are acceptable.
Panel subs:censored:ution is provided in order to give the opportunity for a racer to run a mower that
might otherwise be sidelined. Panels may not be subs:censored:uted simply to modify or customize a
mowers appearance. Panel subs:censored:utions that make a mower look radically different than other
mowers in a class will not be allowed.
Fiberglass parts are permitted as subs:censored:ution for metal parts when metal parts are not available.
Modification:
The hood and/or its components may be modified to provide clearance to allow tires to turn and
steer without contact with sheet metal.
Sheet metal maybe bent or cut to allow for clearance of modifications otherwise allowed such as
air cleaners, exhaust, brakes, clutches or other controls.
Openings cut in sheet metal shall not be more than 2 inches from the obstruction.
Fenders may be modified to allow for tire clearance issues due to chassis lowering as well as for
handling purposes. Allowable modifications include:
Trimming fenders such that there remains ½ of clearance between the fender edge and
all
sides of the tire.
Flaring of the fender such that there remains ½ of clearance between the fender edge and the
top of the tire.
1 of vertical material must remain on the fender. This will ensure the structural integrity of
the fender.
Fender trimming should follow the contour line of the fender, not merely remove sheet metal
in the immediate area.
Fender trimming or flaring that results in sharp edges will not be permitted.
Removal: Any sheet metal originally on a mower may not simply be removed. A mower originally
delivered with fenders must have fenders. A mower originally delivered with a hood must have a hood.
ll. Race numbers should be a minimum of 3 high and of a sharply contrasting color from its
background, and be visible from all four sides of the mower including the rear . Mowers without
numbers or mower with same number will be assigned one during registration. Mowers will also have
class designation letters of the same size. See individual rules for class abbreviations.
mm. All mowers must have a functioning mechanical clutch. No chain drive from engine to
transmission is allowed.
nn. Mowers must present a neat and clean appearance. No written profanity is allowed.

ARMA Point Structure
Drivers participating in ARMA sanctioned national points races will receive points for their participation and
finishing position. These points will be recorded with the national office on a database that covers all ARMA
racers. Points will ac:censored:ulate through the racing season. The United States is divided into four regions.
Racers living in Maine, New Hampshire, Connecticut, Rhode Island, New York, Maryland, Delaware,
Pennsylvania, New Jersey, West Virginia are competing in the Northern Region. Racers living in
Virginia,
North Carolina, South Carolina, Georgia, Tennessee, Alabama, and Florida are competing in the Southern
Region. Mid-west Region drivers are designated as those living in Michigan, Ohio, Indiana, Illinois,
Wisconsin, North and South Dakota, etc.
West region drivers are identified as those living west of the
Dakotas, Nebraska, Kansas, Oaklahoma, and Texas.At the end of the season, drivers are awarded full points for their top 5 National Points Series races. These
points are be used to identify a Northern, Southern, Mid-West and West Series points champion (also second
through fifth place drivers) in each class. This enables points winners in the top 5 positions from each class in
all three regions to go to finals and race it out to determine an overall champion, second and third in each
class. Drivers competing at finals will bring with them points based upon their final ranking for the year- 400
for 1st, 350 for 2nd, 300 for 3rd, 250 for 4th and 200 for 5th. At the finals the top twenty drivers in each class (5
Northern series drivers , 5 Southern series drivers, 5 Mid-West, 5 West) will have starting positions secured in
the front of the grid. The top twenty drivers will draw for positions 1-20 on the grid for their class (number
may change if less than all eligible drivers travel to compete in finals.) Other drivers in the same class will
draw for the remaining positions. Finishing points will be awarded just as in any other National Points Series
races. The regional driver with the highest point value for the day in each class will be designated as the
champion. Second place through fifth place national points series winners would be identified in the same
way. Ties will be broken using the following criteria- greater number of wins regionally, greater number of
national points races attended, third criteria tbd (if necessary) by the ARMA Board of Directors.
In order for a mower class (and its drivers) to be eligible for regional championship level recognition
there must have been a minimum of three mowers competing in the class at a minimum of three national
point series races.Point Values:
50 points for registration

TRACK PROCEDURES FOR 2012
The Track Steward position will be carried forth as a service for the racers of ARMA. This position is in place
to improve track safety and the accuracy of decision making. We will try to have at least four radios in place at
each event. The Track Steward along with the Head Flagger and two Corner Flaggers will when possible be
wearing head sets. The event announcer will have a radio with an external mike so he/she can listen in and be
another pair of eyes when needed. Our goal is make the race safe, fair and enjoyable for all. Below is a list of
operating procedures.:
1. Whenever possible the track will be set up with Head Flag Person located at the entry to the track.
2. The Track Steward will be the last communication with the Head Flagger who will declare the race
ready to begin.
3. Gridding for the next class will be outside of, but nearby the entry point. After the previous race is over
and all racers have exited the track, racers will then be invited onto the track. Once the starting grid for
a class is on the track, the entry will be closed and a red cone placed at this point. If a driver misses line
up, they will pull up to the cone and WAIT to be invited onto the track by the Track Steward. Every
attempt will be made to permit the driver to race. If during ANY racing activity you leave the track, do
not reenter the track until you are invited by one of the flaggers or Track Steward. Any unauthorized
entry will be black flagged.
4. Incidents such as bumping, cutting racers off and other unsportsmanlike behaviors will be monitored by
the track personnel. The flagger who has the best view of an incident will contact the Track Steward
through his/her radio. Input from all flaggers will be considered, but ultimately the final decision will
be by the Track Steward. In order to maintain the greatest degree of fairness the decision rendered will,
whenever possible, be by more than one person. Drivers are urged to keep in mind that the track
personnel are located at key points around the track and therefore are most of the time better able to
view incidents than anyone else
5. When a call is made regarding a line up or a driver is sent to the rear, no discussion about the call will
transpire on the track or from the pits. All calls are final, not responding to a call will result in a black
flag to the driver.
6. Races will begin with a side-by-side rolling start. Two attempts (including the original start) will be
made to start the race. If after two attempts a flag is thrown, the line up will be single file. The driver
causing the restart will move to the back of the pack. At that point everyone will simply move up one
spot (if the person in front of you caused the flag he/she goes to the back and you move up, same with
the person on your side.)
7.
Any mower involved in an accident will be inspected and approved by an ARMA / BTMRA staff member before
being permitted to return to the track and compe:censored:ion.8. Anyone who dismounts a mower in anger will be removed from the track for that race. Anyone
touching another driver or official in anger will be removed from the property where the race is being
held.
9. Know your flags! Red means stop as soon as it is safe to do so, not slow down. Drivers will be given
one warning for an on track incident. They will be shown the black flag in a rolled up position. If a
driver is shown it a second time in the unfurled position, they must exit the track.
10. Drivers breaking down on the track will be provided two caution laps to make repairs. Once the mower
is repaired it will be placed at the rear of the field. If after two laps repairs will not permit the mower to
continue it must leave the track (racing area). When drivers see a yellow flag flown they should raise
their hand so others know mowers are slowing down. Drivers should use the same sign anytime they
leave the track.
11. When the race is over take a cool down lap and then exit the track at a safe speed, maintaining
appropriate speed in the pit area.
12. When the Super Stock/JP drivers are finished they should exit the track, stopping as close to the track
as is safe to wait to have their RPM and gear ratio checked. NO ONE WILL BE CHECKED ON THE
TRACK. If a hood needs to be removed, it must be off when the tech inspector arrives to check the
rpms. There must be clear access to the spark plug wire in order for the mower to be checked. It will
be up to the tech inspector if he/she feels able to safely tach the machine.
13. We apologize if you encounter a situation where you feel that you received what you perceive to be a
bad call. We will do our best to ensure that this does not happen. But, in the event it does, please do
not stop the race. After the race is over any concern you may have will gladly be discussed.
Flaggers: As we do not have designated flaggers, we welcome anyone who wants to help. However, we ask that
you conduct yourself in a professional manner and stay off the main track and behind the bales/barriers. Please
only go on the track to assist someone under yellow, black or red flag.
ONLY designated flaggers are allowed on the track, no further assistance is needed. Due to insurance
regulations no persons except track personnel are allowed onto the track.
When you decide a flag is warranted, throw it quickly and with authority. If you slip part way through your
decision to throw the flag-throw it anyway! A half thrown flag could cause a wreck. Restarting the race is not a
problem.
Remember that we race for fun, friendship, trophies and very often to help deserving charities. No one wants
their hobby to land them in a hospital. Keep this in mind as you race in a safe, respectful, professional manner.
