I'm new to the owning a tractor but have ran big deere 81-83 series for a larger farm operation. I bought a compact for my acreage. After buying the machine from a auction with 1300 hours for a good price I replaced all fluids an ordered bought a manual on ebay. And read up on my tractor started to get the feeling of the tractor. the dif lock when I press the lever down I can't tell if it engaged. Normal big tractors you engage it the way to kick it out is to tap on a brake pedel. But I only hear brakes squeak. Anyone have any thoughts or experience with a dif lock on a deere 1070
