I just bought a 1961 1010 and looking at all the negative talk about this model but didn't really see a list of the real problems. What are the major problems and their fixes? I've noticed a slow leak down in the Hyd system so far. I hear there is a o'ring problem on the engine sleeves. Is there no fix for this? Are the sleeves only available at the dealer? Don't see them in aftermarket supplier. I've also noticed with PTO engaged I can't shift into gear is installing an overrunning coupler the answer to this? As much info would be Great as I try to decide if I want to keep this tractor. Thanks in Advance...Mike
