I went ahead and bought the 1155 that I asked about earlier. But only pd 2000 for it.I asked a lot of questions.Finally decided go for it. take a gamble.The problem seems to be the priority valve.I will do some pressure testing...... If it is a "boat anchor",I'm not out much. It will go to auction in the spring.It really is a very nice tractor. My question: it has the factory taper/wedge lock hub duals. Is there a special 'jackscrew' to push the wedge from the wheel? The regular bolts are too short and do not reach the wedge.Any special tricks?I want/need to remove the duals..Thanks,Steve
