Gotta love finding a forum on John Deere tractors, this is great.
We have an '89 265 Hydrostatic with the 17 HP Kaw engine, mower deck and we used to plow with it then we purchased a Grizzly to take that chore as we get quite a bit of snow… I still keep a plow on it but just to clean up vs. doing the primary duty. Wheel weights and chains, sweet rig.
My Wife actually bought it for me new for Christmas in ‘89. What a girl..!
I did not even mount the mower for several years, I wanna say maybe more than ten years before I hooked it up and it has really seen little use…
I will try to make this a short story but the issue is complicated.
Well, last year it tossed a mower drive belt at the end of the year so I took the deck off and really did not think much of it until this Spring when I went to put a new belt on.
I put a new belt on it and it tossed another one. That is when I discovered what caused the belt to be spit out…
This time the rear dual pulley crashed into the front of the hydro unit and bent the channel for the belt rendering it unusable. Those are spendy huh…?
The entire deck looks to be set rearward enough (Duh, hence the crash..) to drive that pulley hard into that housing. But why…?
Well, I measured and looked under the tractor and measured some more on the deck, bought new rear hanger brackets and front adjustable tie bars and that read dual pulley. The rear bracket bushings were a little warn but nothing that would cause that much movement.
When I installed the new front bars I adjusted them tighter as to pull the deck forward and the pulley Still hits that hydro housing.
The only other thing that I see is that the mounting points of the rear hangers may be slightly tilted forward which, in my limited knowledge of trigonometry suggests that there might be the issue. However, there is no way that those mounts have been bent, they are ¼ angle and the welds do not appear to have been comprised. There are no other signs of the deck being bent
I am not going to put the new belt on just to trash it until I figure this out but I am out of ideas here.
Any advise or ideas what could be causing this alignment issue is most welcomed. I can post photos if need be… In fact I will go out and shoot some right now.
My most sincere apologies for such a long winded first post.
Thanks very much,
