MOD-X / MX / CP:
•   Engine must maintain stock outward appearance, with the exception of the air filter, air cleaner or velocity stack.
•   Crankshaft must be in original orientation and clearance hole in the frame.
•   Engine may be internally modified.
•   39” minimum wheelbase
•   Mid-engine frames not allowed
•   5” minimum front wheels, 6” minimum rear wheels
•   Crankshaft must be in original orientation


All mowers racing the FTFMR Series may utilize "Kart" tires. Understandably, minimum frame height rules will change due to tire diameter, but will be considered legal.

General Regulations

1. On Track Regulations

Any deliberate actions to circumvent 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 Local Chapter representatives and/or their board of directors. 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 starter’s 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.
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.  Driver’s 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 to a safe place at least 10 feet off course.
•   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 circumstance 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 day’s 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.
•   h.  No pets are allowed on the racing course.
•   i.  Individual tracks reserve the right to limit pit space. Campers and RV’s 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.

•   b.  Prepared class drivers (Super Stock class and above) must be at least 16 years of age. Drivers under 18 years of age must have an approved parent’s consent form on file.
•   c.  Drivers should conduct themselves in a professional, mature manner while on the track.  If a driver feels there is an issue requiring attention, he/she will bring the issue to the Chief Steward in an appropriate manner.  Failure to do so will result in removal from the remainder of the day’s racing action.

4.  Driver Safety Equipment

•   a.  Every driver must wear an automobile racing or motorcycle-type full-face helmet approved by the U. S. Department of Transportation or the Snell Foundation.
•   b.  The helmet must fit snugly and be securely buckled when driver is on the track.

5.  Mower Eligibility

•   a.  Events are open to all riding type lawn mowers and garden tractors (with tires 20” or less) that were mass-produced and commercially available to mow residential lawns.  Zero turn riders are not permitted.  The mower may be modified from its original configuration as noted in section 7 General Mower Specifications Modified Classes.
•   b. Final determination of eligibility and classification is up to the technical inspector.
•   c.  Organizers reserve the right to reject at any time any mower, which in their opinion, represents an attempt to defeat the spirit of these rule, even though it complies with the letter of them.
•   d.  A single mower may participate in multiple classes, however points will only be awarded  for the class the mower is built for.  This will be identified by using the class letters on the machine.
•   e.  Driver's owning two machines prepared for the same class may race one machine in the heat and a second mower in the feature.  Both mowers must pass through technical inspection prior to the start of the day's racing action.  If a driver utilizes a back up mower, that driver must start at the rear of the field.

6.  Technical Inspection

7.  General Mower Specifications- Modified Classes

•   a.  Cutting blades must be removed.
•   b.  Cutting decks must be securely mounted in near stock location.  Only Pro-X and Super Modified mowers may simulate a cutting deck.   Decks may extend beyond the tire sidewalls a maximum of 2”. Decks must be as wide as the body edge or running boards whichever is wider.
•   c.  Mowers must maintain a minimum of 2.5 ” ground clearance under the lowest point of the deck except Super Modified class mowers.   
•   d.  Mowers must maintain a minimum of  4” of ground clearance under the lowest point of the frame except Super Modified classes. Unused brackets and non-structural material may be removed to gain clearance.
•   e.  Exhaust design is open, but must terminate away from the driver and competitors, in a rearward and downward direction without creating a safety hazard.
•   f.  Starter and functional battery must be on board, either electric or pull rope in all classes except Pro-X.
•   g.  Rear wheels must be secured to the rear axle with shaft locks, center bolts or thru-bolts.
•   h. All non-stock mowers shall have an automatic, throttle closing device.
•   i.  Kill switch lanyard length shall be as short as necessary to effectively stop the mower as quickly as possible. Lanyard length shall not exceed 40” when fully extended. This device must be commercially available for racing and/or recreational vehicles such as ATVs, jet skis snowmobiles, etc. Homemade and/or magnetic switches are not allowed.
•   j.  Mower brakes on any Sportsman or X series mower must be upgraded to a brake system on the rear axle.
•   k.  Brakes may be hydraulic or mechanical.

•   m. The steering wheel, seat, body and frame must be centered between the right and left wheels. Offset is not permitted. See Super Modified Rules.
•   n.   Drive line may be modified from the engine pulley to the rear wheels. All classes except Pro-X and Super Modified must use a shift able lawnmower transmission or transaxle. Vari-drives may be used if originally equipped.
•   o.   No centrifugal or torque converter clutches permitted in any class except Pro-X and Super Modified.
•   p.   Rear axle may use open differential, locked, live or solid axle. No single wheel drive.  Aluminum rear axles are permitted.
•   q.   Wheels must be the same size on each axle, of any origin, but made of metal. Duel or tandem wheels are forbidden.
•   r.   Front axle and steering may be modified or fabricated.  Front axles may be pinned, bolted or welded into place.  No suspension allowed.  All modifications and fabrications are subject to the judgment of the technical inspector.
•   s.   All steering linkage must be ball-type or spherical threaded rod ends.
•   t.   Footholds and seat side boosters must be minimally designed so as not to entangle body parts.  Foot guards should be no higher than 4” from the bottom of the bar to the top and be flush with the bottom of the frame.  Bars should be 2” off of the rear tire.  With wheels turned to extreme position, there should be 2” of clearance between tire and bar.
•   u. External ignition systems and aluminum flywheels are authorized.

 It is highly recommended that there 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.   Recognizing that other sanctioning bodies are extending their implementation date for mandatory billet flywheels, we will permit drivers to continue to run their stock flywheels for the 2011 season.  By doing so, drivers assume all risks related to running said flywheel.   
•   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 alone, bent nails, hitch pins, over center pins and quick-release pins are not permitted.
•    w. Mowers may reach a maximum width of 38”sidewall to sidewall except Super Modified classes.
•    x.  Carburetors must be of lawnmower origin and from the same manufacturer as the engine block. Prepared mowers participating in the Mini-Sportsman class and above will be required to have dual return springs on the throttle.
•   y.  Mowers may only operate on pump gasoline. No additives or additions to the fuel  are allowed.  No nitrous oxide, rocket fuel, alcohol or other oxidizers are permitted.  No combustion enhancing substances may be added to the crankcase oil or air cleaner assembly.  Any attempt to circumvent 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.  Substituted 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.
•   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 Ύ”outer 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 competition.  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:
•   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.
•   Substitute 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.
•   Substituted panels must be modified to fit properly and safely.
•   Minimal under hood mounting brackets are acceptable.
•   Panel substitution is provided in order to give the opportunity for a racer to run a mower that might otherwise be sidelined.  Panels may not be substituted simply to modify or customize a mower’s appearance.  Panel substitutions that make a mower look radically different than other mowers in a class will not be allowed.
•   Fiberglass parts are permitted as substitution for metal parts when metal parts are not available.

•   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 the top 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.
•   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.
