I just recently acquired a JD 322 which has a factory JD three-point hitch, and was wondering if I can convert my Model 30 hydro tiller (30" with 12" extension) to a three-point hitch configuration from the normal two-point hitch?

I saw a later-model 42" hydro tiller on a JD455 which looked as though the housing was the same as my Model 30 - model number 2697 - which had a three-point tower lift.

When I compared my 30 tiller (model 1988) with the later 42 tiller (model 2697) it looked as though the mounting flanges for the three-point lift assembly would fit my mounting areas.

Am I correct in this assumption, and would I be able to retrofit the model 2697 mounts to my model 1988 tiller?

Thanks!

Randall,
I think the mount on that 400 series will bolt right on. I did just what you are talking about. I converted the "four point" tiller mount over to a cat. 0 three point. I will look for the measurements tonight when I get back home. I think I have some pictures too. If you can weld it is easy to make. It also works very well. I did mine like three or four years ago.

Randall and Paul,

Using the 3-pt to lift the 30 tiller works out just like stock of you have the 5/8 pins on the rockshaft like that latest versions of the factory 3-pt units did. The lower mounts are a bit different for the tiller than the 3-pt, and provide some adjustment as to 'agressiveness' and 'depth' of till per the manual.

Here is a drawing and table that might be of some help:

There is a lot of useful info in Jim Briney's thread on this topic at:

Randall,

Last fall I purchased a 30 hydro with a 3 pt already installed - just what I was looking for since I intended to use other 3 pt attachments. I really can't compare to the two point configuration, but so far, I'm happy with the design. It may be an aftermarket 3 pt bracket. Others may have insight as to whether JD makes one.

Putting on the belly pump wasn't so bad, but hooking the belt to the mule drive was a pain.

I need to rig something to hold the hydro hoses off the ground - right nw, they are secured with wire ties.

JD does make one for the newer 42" Hydraulic tiller, which will bolt right onto the 30.

I am also going to have a few for sale that Im making, hopefully in the next 2 weeks.

They are out there if you dont want to make one yourself.

William,

Here is the Deere approved method for holding the belly pump hoses off the ground as they pass under the rear of the tractor:


The hook is actually a dual use -- it serves as the right hand retaining pin in the lower mount bracket. There is a full description on the operator's manual, OMM 89022, but here is a shot of the loose parts that should have shipped with the tiller when new...


Let me know if you need an excerpt of the manual where the use of this hook is described...
