Since there seems to be some confusion, These rules were implemented to differentiate between classes when sanctioned events are held. The all-class mandatory rules are mandatory due to safety reasons and to thwart off back-yard-bashers (BYB).

The PDF file of the forum rules will be modified in the near future so we can clear up any concerns




· Approved PPE (helmets, pants, boots, gloves, etc.)
Self-explanatory. We don't want to see you getting injured
· Tech approved muffler (no louder than [to be determined] decibels)
· USDA Forest Service approved spark arrestor
We don't want you to annoy your neighbors or start a fire with your mowchine
· Tether safety shutoff device
We don't want to see you fall off your mower, and then have it drive away and injure someone/something
· Steering must be upgraded (tech approved no-slop – see class rules)
sloppy steering + off-roading = crash
· Automatic throttle return
You don't want your engine racing at 5,000RPM when you're drying to slow down
· Upgraded on-axle brakes that will hold the mower on an [to be determined] in/decline
You need to stop, and you need to stop safely. Transaxle/transmission brakes aren't designed for what we do
· Wiring must be safe and pass tech inspection
           o All positive leads/connections must be covered
We don't want to see hack job wiring that's going to short out and leave your mower stranded, or worse; catch fire.
· Front-facing headlight and rear facing tail & brake light**
After the sun goes down, you need to see and be seen
· Every 2” lift axle must be widened 1”
Stability is a key component to a capable off-road mowchine, You don't want to roll over ever, especially on an incline.
· Front & rear bumpers with tow hooks (brush guards, skid plates & slider bars may also be used and are recommended)
You'll get stuck, and you'll need these. Trust us, it'll happen.
· Fully working clutch
You need to stop believe it or not.
· All edges must be rounded
I personally don't want to see cuts or gouges or people bleeding from a laceration due to a sharp or jagged piece of metal.
· Motor originally produced to power a ride-on mower.
This is off-road mowers, not take an ATV and put mower sheet metal on it.com (There are exceptions to this rule)
· Front axle pivot must be removed, welded, or bolted solid
Again with the stability...
· Aftermarket or custom spindles and heim ends must be used. No factory setups!
           o Limited class exempt
Ever have a steering component fail at an inopportune time? You will if you don't upgrade them.
· All wheels must be held on by a bolt, lock collar, or set screw
Ever loose a wheel? Well we don't want you to.
· Mower must have a recognizable and noticeable "tag" or sticker stating its class
           o L or Limited
           o M or Modified
           o S or SuperMod
           o X or Outlaw
This applies if you plan on running in a sanctioned event
· No tires larger than 22” with 10” rim MAX (with the exception of 26" x 12" x 12” in limited)
This is not monstermowers. 44" Super Swampers on your mower are ridiculous.
· No open differentials on 2WD machines
You'll get stuck, a lot.
· Open differential REQUIRED on the FRONT of all 4WD machines (limited slip/locker can also be used). Rear must be fully locked
If your front axle is constantly locked, you won't be able to steer - and when you try you'll brake driveline components.
