2009 RACING SEASON

The United States Lawn Mower Racing Association (the USLMRA) is run primarily for
racing enthusiasts and their friends. Members race for the love of competition. All who
share this philosophy are welcome to join the USLMRA and participate in its activities.
These regulations, which include any supplementary regulations issued for a particular
event (collectively, the “Regulations”), are designed for the orderly conduct of lawn
mower racing in the United States and to establish minimum acceptable requirements for
such events. However promulgation of these Regulations is not an admission that the
USLMRA has the duty to warn participants of potential hazards of participation.
Moreover, these Regulations are only intended as a guide for the conduct of the sport and
are in no way a guarantee against injury to the person or property of participants,
spectators or others, nor are they a substitute for the due care which should be exercised
by participants in any event. Finally, the USLMRA assumes no liability discharging the
USLMRA from such liability.
The USLMRA reserves the right to accept, deny, suspend or revoke any membership at
any time.
The USLMRA Staff, having promulgated these Regulations, may modify,
add to, delete from or grant exceptions to these Regulations at any time. By entering and
participating in these events, all participants agree to abide by these Regulations, as may
be amended from time to time.
Notable changes to the 2009 USLMRA Rule Book

Throughout the year we have spoken to many drivers, gathered recommendations and analyzed this information. With this said the following changes have been changed or added to the 2009 USLMRA Rule Book.

Section II RULES OF THE PITS & GRID
K) No pets are allowed on the racing course. Pets in the pits must remain on a leash and owners are responsible for cleaning up after their pets

Section III Driver Eligibility:
B. Drivers must be at least 18 years of age. Drivers 16 and 17 years of age may compete with an approved parent’s consent form on file with the Race Day Chief Steward at each event. For JP drivers A Parental Consent form can be filled out by a parent or legal guardian prior to the event.  However, it must be an original, and it must be notarized.  Note that this applies to the first time you race at a facility.  Once one is signed for a particular facility, it is good for the year.
 
Section IV. DRIVER SAFETY EQUIPMENT
F) An approved, racing neck support is MANDATORY in JP, IMOW, Prepared and FX.

Section VI. TECHNICAL INSPECTION
A) Every mower entered in any USLMRA event must be approved for competition
by Technical Inspection before practicing or racing at any event. A Safety Tech/
Build Tech sticker will be issued at each race. Top five finishing machines may
be required to go directly from the track to the impound area (when provided),
and be inspected for Build Tech compliance. Failure to impound directly from
the track may be cause for automatic disqualification and loss of points. All JP’s & IMOW’S will remain on track for RPM & Air Pressure check Inspection after feature races. JP & IMOW racers may be required to check gear ratio compliance as a group, participation is mandatory.

Section VII. GENERAL MOWER REQUIREMENTS
Handlebar type grips may not be added to steering wheels in any class.

Section VIII. RACING CLASSIFICATIONS
E) FACTORY EXPERIMENTAL
16) Handle bar type grips can not be added to steering wheels!

USLMRA Points Structure:
•   If a Yellow or red flag is thrown before the lead mower completes the first lap, the race will be restarted but only once, if a second yellow/red flag is thrown before completion of the first lap, the race order will be determined by the order the mowers crossed the Start/Finish line at the start.


Racers:
As we get ready to begin the 2009 season, we all look forward to a new year of exciting, competitive, and safe racing. As we did last year we have committed ourselves to ensure that the new 2009 USLMRA Rule Book is ready for issue before the 2009 racing season kicks off. Please note that there are some minor changes to the rulebook for 2009. The 2008 version proved to be an excellent document and required just minor changes.
Most changes were created to clarify some existing issues and address safety issues where necessary.
For questions concerning these rules, we highly recommend addressing them on
the FREE Yahoo Club site at http://groups.yahoo.com/group/USLMRA, or the USLMRA Message Board site at http://www.uslmra.com/, so our members may see the questions and answers. You may also contact the designated staff members by e-mail for answers to any questions you may have.
Let us all remember that we should strive to maintain professionalism in our
appearance and conduct, and we hope to keep participation fun, affordable, safe and
competitive. For those who wish to spend time seeking loopholes in the rulebook, or
defeat the spirit of the rules, we suggest you are racing in the wrong organization.

Sincerely,

Bruce Kaufman—USLMRA President
Brooke Highline—USLMRA Vice President of Administration
Manny Torres --- USLMRA Race & Technical Director

Home of the STA-BIL Racing Series

It is the responsibility of the builder and driver to adhere to, and be

    transmission must use an axle-mounted brake system.
  
5) Body: Must be stock, without external alterations, although discrete strengthening is
    allowed. Hood must be secured. Also Hoods must be hinged or a hole in grill for
    access to spark plug wire for “RPM” checks. Minimum 4” ground clearance to frame,
    2 ½” from the ground to the bottom of deck. Footholds must be discrete, and no more
    than 2” high, made of flat or “L” stock (no rod stock), and made such that the foot can
    not become entangled in a rollover.

6) Deck: Mowers must mount steel factory decks. The deck must be at least as
      wide as either running boards or body edge whichever is wider. Decks may

    not sufficient for wheel retention and are not approved. Rear axle may use open
    differential, locked, “live” or solid axle. No single wheel drive.
Cool Steering; Front axle and steering may be reinforced, substituted or fabricated. In the
    Case of racer-fabricated axles, these will be subject to the judgment of the Technical
    Inspector as to their apparent safety for racing.

Aluminum may not be used as the material for the one-piece axle.
  
9) Wheelbase; Minimum 39" unaltered. Width; Maximum 38” sidewall to sidewall.

MODIFICATIONS NOT LISTED ARE NOT APPROVED

INTENT: To provide a safe opportunity to demonstrate the driver’s ability when
in competition with essentially identical mowers. This is a highly regulated
class to insure uniformity between JP machines. As you can see, these machines are essentially Prepared Chassis’ (AP, SP, CP, & BP) with IMOW drive trains. This allows young racers to gain race experience at IMOW speeds which will approximately reach 15-20 mph (on a USLMRA US Points Track), but with a more stable platform that can easily be upgraded into the prepared classes when the driver reaches the Minimum age.


C) IMOW. Class designation: I

IX. STA-BIL NATIONAL LAWNMOWER RACING SERIES
POINT SYSTEM
AND
AWARDS POLICY

The point system is designed to encourage and recognize participation. Points are
awarded for all STA-BIL National Lawn Mower Racing Series (aka US National
Points”) races, and the STA-BIL Keeps Gas Fresh Finals. Points are awarded and
trophies given for points winners in each class. Series point’s winners will be
announced at the conclusion of the STA-BIL Keeps Gas Fresh Finals. First through
fifth place points winners will receive prizes and/or trophies. You are still allowed to
make each and every Nationall Points Race, should you have the time, money and
desire. Your participation is always encouraged.

When figuring the points standings, USLMRA will only use your four best finishes.
On “Finals” Weekend, there will be one final points race (the STA-BIL Keeps Gas
Fresh Finals), which will also be counted toward your National Class Ranking. This
means you will have your four best STA-BIL National Point finishes plus the STA-BIL
Keeps Gas Fresh Finals being added together for your final points total.

1) The STA-BIL Keeps Gas Fresh Finals (formerly referred to as the STA-BIL
Nationals), is not an open race. Participants must qualify by class competing in
a minimum of two (2) 2009 USLMRA STA-BIL National Lawn Mower Racing Series (aka US National Points”) races.  NOTE: To compete means to complete at least one race lap under power.

2) Championship weekend will consist of a practice day (09-04-09), the STA-BIL
Keeps Gas Fresh Finals and the qualification race for the Challenge of
Champions (09-05-09), and the Challenge of Champions, (09-06-09).
   a. The STA-BIL Finals will be run Saturday, (09-05-09), to
   determine the points champions per class.
      i. The current top ten in points in each class will grid in the first ten
      starting positions with order determined by random draw.
      ii. The starting positions for the remainder of the grid will be determined
      by qualifying heat(s). If qualifying heats are not required, griddling heats
      may be substituted. The Race Day Chief Steward will make this
      determination.
   b. Drivers not qualifying for championship point trophies may race in the
   qualification race Saturday afternoon. The top ten finishers of this race will
   join the STA-BIL Finals Points championship winners and up to three
   racers-at-large, selected by the USLMRA President for the Challenge of
   Champions, to be run Sunday, (09-06-09)



USLMRA Points Structure.

   100 points each for registration, starting and finishing a point’s race
   100 points for 5th
   150 points for 4th
   200 points for 3rd
   250 points for 2nd
    300 points for 1st
   Note: Mower must cross the finish line under power to receive points for that race    unless    mechanical failure occurs on the white flag lap. (The mower can then be    pushed by the driver only across the finish line.)

•   A racer is allowed to race and receive points on an individual mower in one race class only in a race event.
•   A racer may race a legal mower in a second race class with the permission of the Race Day Chief Steward only.
•   Races officially start after the green flag drops.
•   The race is defined by the first complete lap on the lead mower.
•   If a Yellow or red flag is thrown before the lead mower completes the first lap, the race will be restarted but only once, if a second yellow/red flag is thrown before completion of the first lap, the race order will be determined by the order the mowers crossed the Start/Finish line at the start.
•  

**Racers will receive no points or race credit towards Qualifying for the Sta-Bil Nationals for any race they received a disqualification (DQ).**


Code of Conduct for USLMRA Members

The United State Lawn Mower Racing Association (USLMRA) expects its staff, Local Chapter (LC) Presidents, racers, general membership, and volunteers to always act in a courteous, professional manner for the benefit and growth of lawnmower racing.
   The USLMRA reserves the right to accept, deny, suspend or revoke the membership of any member, or place any member on probation, for any action(s) deemed detrimental to the sport of lawnmower racing.
