I am working on a Troybilt (MTD) 33" Wide cut walk behind 34071(made by Garden Way). The tractor 1/2" V belt was replaced with an original MTD (1770334) per the exploded parts list part number. I routed it the way the old belt was on. When I tested it, the wheels will not clutch. Even with the clutch pulley at its loosest setting. This a non coated belt. It seems to stick really well to the v groove in the drive pulley and will not release when the clutch pulley is released. I went to the manual and saw a different routing. When I rout the belt as shown in manual there is about an extra 6 to 7 " of belt. It won't work that way. It will fall right off.
I put the old coated belt back on in the way it was routed. It seems to somewhat work. When the cluch is released it does take 3 or 4 seconds before the wheels are not driven. It seems the coated belt is the way to go ....at lease with this routing.
It seems there is an error in the parts look up documentation. Since this is about a 20 year old machine, you would think they would have corrected the part number by now. Maybe not the belt routing in the drawing but certainly the P/N as I am sure they get a lot of calls.

I may have to buy a couple of shorter belts and experiment. The routing in the diagram makes the most sense. Anyone run into this before and what belt did you eventually end up with? I am thinking a coated belt would be better. Thoughts in general? I generally find MTD to be good with documentation. Frustrating.!!!!
