Without a shop manual I wouldn't be able to figure it out. The next time I go to "the big city" I will stop in at the tractor dealer and talk to them about the issue. Maybe they can help me with some info. Maybe copy a few pages from the shop manual, or I might have to bite the bullet and buy one. Last time I checked, the shop manual was around $450 US, before shipping, duty and taxes. That would make it close to $700 Canadian without duty or shipping charges. I found sites that will email a copy for $20 but after some research I found some of those sources are not trustworthy.
