Have a toroLX500 my question is that when it is cold and you start to cut grass all is well. After it warms up and gets hot, tractor will not move. You push in pedal and goes no where. Then it catches and moves forward. Only does this when Tractor is hot. Have had it to a few people and can't seem to find answer. I ask them to let it run for awhile and nobody has time to do this. Does it have to do with some cable that gets hot or a adjustment of some sort. get called ever time she cuts grass
