I just bought my first snow cat serial number is on frame on front right is SV301 571D. I am guessing it is a 301 ski dozer, its fully hydro-static Does anyone know what fluid goes in the high low gear box that bolts to the motor? Also, the 3 gear boxes on the back of the machine by rear axle? And what hydraulic oil it takes? I think the hydraulic is suppose to be ATF Type F and all the gear box runs 220 Is this accurate? I want to service it for the first ride i go on with it.
