hydrostatic drive

[patrician12]

Just bought a used tractor with a snowblade and no manual.It has hydrostatic drive.All my other 6 tractor have manual gearboxes.So,I have a few questions.When plowing and it hits a lot of resistance the wheels stop turning without any unusual noise.I assume therefore that no damage is happening.Is this normal?Secondly,it is much slower than standard gearbox.Isthis normal?Finally,what type of oil does it take?

Keith What make and model tractor is it? No it is not normal. First thing to try is change the hydro fluid and filter. It probaably never has been changed. The fluid is ATF dextron mircon will work. Top speed should be around 7mph.
