Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is ***** ***** me review the issue, and I will be more than happy to help resolve it as quickly as possible.
if both belts are new, I would check that the pulleys are working properly. check the inside grooves for smoothness and also shiny grooves as this would allows belt to be slipping in pulley. Check that the idler pulleys are all properly installed and moving when supposed to as well
I will OPT OUT as if you have new belts and all pulleys are good, belt is routed properly, there is no reason for machine to slip going up hills. Please DO NOT respond as t will lock question back to me and another expert cannot answer for you
