O.K. I guess in my case, working on the grandson's John Deeres has gotten to be sort of a Grail pursuit ! But the better they get rebuilt, the better they work. And I keep finding things to improve/upgrade/make stronger so they don't fail again. Biggest problem, even old, rusty parts cost like gold, and some things just don't exist as repair parts. So I fabricate & re-engineer as necessary. Almost done with the bottom of the 60" mower we've been working on for 3 weeks now, just about ready to flip it & start on the top side. Looking for replacement gage wheels now, even if they were still at JD in the parts counter, they'd be far overpriced. Nice thing, the old ones have the mfgr's. name on them. JD don't make a lot of things on their equipment, like everybody else, they have suppliers. All I need to do is locate them. Usually parts like the wheels can be found for about 1/4 of JD pricing ! When I get done with this one, I will drag my bike out & ride, or at leastattemptit !
