Tell me what's not included with your warranty. Failures, beyond operator damage, that will make your warranty void.
I say this because Kohler rejected a warranty on a 14 hp engine with us because internal oil channels were plugged and did not lube the top portions of the engine properly, although adequate oil was in the machine and on the proper service interval.
Since propane has additional wear issues over gasoline, please respond.
Right now, Kohler is on our reject equipment powered by list and has been since 2004.
