I have an early Super A that I just bought a front blade for. After hooking everything up I was excited to push something, but the lift doesn"t have enough power to get it off the ground unless I helped it with a six foot rock bar. It seems to have plenty of down pressure. I have a 3-point finish mower that I used last year and if I remember right, it had problems lifting it also, but had enough power to bend the rod that connects the 3-point to the lift. I have never done anything to the tractor except oil change, grease, and some electrical. Where do you start looking? The manual lists the oil in the Touch Control system to be SAE10W. What modern fluid is recommended to replace it with. I have only had the tractor for a two years and I don"t know what fluid is in there now and I don"t want to mix types.
