What kind of oil goes in a hydrostatic transmission?
The fluid recommended for Hydro-Gear transmissions and pumps is a 20W-50 motor oil or 15W-50 synthetic motor oil If the machine has oil reservoirs, they are mounted to the frame behind the seat, for easy access and oil level check accessibility
How long should a riding lawn mower last?
