Lawn Mower Classifications:
(Basic differerences only)

Race mowers will only be allowed to enter and race in the class that they were built for, ie, AP in AP, SP in SP, CP in CP, BP in B, FXS in FXS, & FXT in FXT. The JP and IMOW classes are the only two that the same mower can run in both classes’ race. GPK and GP can run in both classes also, this is to allow parents or another driver to run in either class.
