Troubleshooting Toro Wheel Horse 14-38 HXL Hydrostatic Drive
I have a Toro Wheel Horse 14-38 HXL Riding Mower w/ Hydrostatic drive. Mower drives okay on flat of decline, but struggles to move on any sort of hill. I want to check and/or change the gearbox fluid, but can't seem to figure how where the drain plug is. There's a rubber hose w/ a plastic fitting on the top of housing. Any thoughts or suggestions on troubleshooting this or checking/changing the gear oil?
