Hey all,
I got the 430 running a few days ago (the link belt worked for the alternator/water pump/crank pully belt), got the 60 inch deck on and it works. Though it has a couple problems: The deck/3 point hitch will only move ~1-1/2 and nothing else, maybe some kind of wrong adjustment? The other one is that the hydro is pretty jerky. If you are at ~1/2 throttle and go forward it jerks out and is kinda rough. And when you stop(no matter where the throttle is), it jerks forward a little bit. What could this be? Any input is welcome! I’m thinking it’s loose linkage, cause if you’re at half throttle and you put the hydro all the way forward, it runs smooth. Thanks

There is a height lock adjustment for the deck/3 point. From the rear of the tractor, look on the left just to the right of the left wheel (under the fender deck). Looks like a bolt with a roll pin on the end facing backward instead of a bolt head. With the deck fully raised, it should turn easily, if it does not, some WD-40 may help. You should not need to force anything, it should turn easily by hand.

If I recall correctly, turn clockwise to lock deck/3-point higher, counter clockwise for lower. It will turn several turns (maybe 10-15?).

I cannot help with the hydro, mine functions normally.

Now I know that there were 4 different versions of linkage over the 430’s production run. But I’m not sure what mine is, does it depend on year? Cause mine is a 87

I also saw that the bolts that hold the tranny to the frame can get loose. Should I jack it up to check it? I know this sounds stupid

NOT stupid, do it!! You'll be better off with tractor in the air and right rear tire off when checking linkage....kill 2 birds with 1 wrench, err, stone. Bob

I haven’t been on here for a while but wanted to cap off this thread. I found that the linkage was completely worn, so I went through it all, and also found out that the tranny flange was almost completely broken off. So I bolted and welded a 3/16” piece of angle, adjusted the linkage, and it’s good to go! Also found out the problem with the deck was that the draft arms needed adjusted. Just wanted to finish this thread, as I know it can be annoying when you never hear back.
