Thanks for the reply. No I have a 1755 with a good engine. It is just that so many on other sites seem to talk badly about a 310, when what I use it for it does a good job ie.(pulling a 720 gallon sprayer and 10ft. no till drill). I am doing my best to take care of the motor with preventive maintainence and not abuseing by overreving. I was just concern if there was a weak link I need to watch for.
