I have a Toro Timecutter SS4235 with a 20 hp kohler, my question is concerning the left transmission or transaxle having a stalling, grinding sound and not engaging when it gets too hot. The mower is a year old and I've read a few similar problems like this elsewhere. I've heard "Take it to a dealer" alot, but Im a small business owner and take pride in fixing my own equipment. I will if I have to but if someone that knows could plz educate me on the right course of action I would be greatful.
