I was wonder if I got a good deal or not on a 1985 john deere 430 with 3450 hours with a cozy cab and plow with rusty floor pan and cab bottoms has heater wind sheid wiper radio strobe light and aux led lights on roof has 125? pound wheel weights and tire chains I think a weak hydro pump ( feels like I'm going in a different gear when going downhill) has small deseil leak and front quick connectors leak a lot of fluid other wise runs and starts good no wiring problems or anything like that. Paid $2,600

Definitely an excellent deal. you can pick up a used whole rear fender pan from a 318 to swap on instead of fixing the rust. They seem to go for $30-$100. Sometimes the linkage or bushings wear out on the hydro linkage from the dash to the transmission and that can cause it to feel weird.

I was kind of hoping someone else thought it was the linage as well not the hydro pump. If it is the pump are they swappable from a 318 to a 430?

if hydro lever has any slop, it afftects the down hill speed and makes moving it jerky

Well that why I thought it might be the hydro pump since it isn't Jerky at all as if some one replaced the dampener

Always check for play in the hydro linkages -- even if you are 'sure' it is not present from exterior observation of the linkage movement. It takes only a little bit of wear to show up in speed changes with slope/grade...

3000 plus hours is more than enough time to have linkage wear...even if it was addressed once or twice before in that total of time of operation.

Wear looks like this:
Office ruler Auto part Household hardware Fastener Metal

Well since it has a cab on it I will wait until this summer when I do a restoration on it but I would total agree that those parts have something to do with the speed changes

Well it has a all steel cozy cab on it right now otherwise I'd have the fender pan off. And my question is are 318 hydro linkages the same as 430 linkages

318 pan does not have the cut-out for the two speed rear end control lever.

My 430 was jerky when I first got it. Turned out to be every bolt that holds the rear end to the frame had worked its way loose.

I should look at that it could be loose after 3450 hours of snow plowing I think it use well taken care of since it was owned by the southwest hospital in IL since there is a sticker on the tractor, plow and cab that says (southwest hospital IL)

Yes your right. I forgot to mention the holes for the 2 speed and I believe the diff lock are missing but can easily be cut.

Now I'm convinced that it'd the hydro because when the blade is a the way up and I try to lift it it make the tractor move/jolt forward faster I'm thinking that by doing this it tries the make the pressure go to the plow but since it's already up it forces the pressure to go the Trans
