I haven't a clue how they did it so. Is Case/Ingersoll setup like many other brands? The reason I ask I may be able to get a set-up from a JD 318 and was wondering if it was doable with a little fab work, or forget it and look for a Case set-up, Thanks John

I think the project is quite a bit more complex than Tom's reply suggests but it can be done. First, the available space in the dash tower is very limited so squeezing all the hoses and other components in there is tough. Second, you will need to replace the main pump so that you have additional hydraulic capacity to run the power steering unit. To the best of my knowledge all of the Case/Ingersoll tractors with power steering had at least 18 hp so doing this with 16 will diminish the power available for mowing and other tasks.

The steering cylinders are mounted on the left side of the tractor so avoid interference with the snowblower/blade lift systems so the spindles will need to be modified.

There are members on this forum who could handle this project with ease but it is definitely not a weekend project.

My 4020PS has the steering cylinder on the right side ( as seated on the tractor)

I did not say that would be a weekend project, now did I? :sidelaugh:

Bart has made some good points but I don't know if they are deal breakers or not. John hasn't revealed why he wants to add power steering. Perhaps this is for a FEL project and that would make sense. Ideally, a slightly larger pump would come in handy but there is no pressing need to go that route for the moment. Yes, the ground speed will suffer somewhat and so will any hydraulic motorized attachments that are connected to the PTO. But for FEL work, none of that matters. The existing pump will still deliver the same pressure it always did and that's what pushes the tractor into a pile of dirt that needs to be picked up.

It has been done by "others" in the past even though clearance is tight. Get everything you can from the Deere. Steering wheel, steering pump, steering cylinder, all brackets and hoses. John will have to remove his engine, battery, oil tank etc but should keep the pump in place for the moment. The existing steering wheel, shaft, gear and drag link must be removed and then the fun can begin.

Having removed the 4 STOCK hoses Sat, I will admit to using some descriptive :twisted: terms.
After you craft up some custom wrenches it becomes easier, still falls considerably short of "fun" :sidelaugh:

New parts on the way from Brian. THANKS !

Funny, it's on the right side on my 4020 PS also. Must have been thinking about my loaders when I wrote that... :sidelaugh:

John,
One of the reasons to belong to this forum, as opposed to some others out there, is that you will often get information that is complete and accurate. Had you asked about that pump you just bought off of e-Bay, my response would have been as follows.


$250.00 for a brand new OEM pump is a steal. However, you CANNOT use that pump for your project. Why? Because that pump is for a 4000 Series tractor, not a 3 digit tractor like you have. When Ingersoll created the 4 digit models, they turned the engines 180 degrees in the frames. This change meant that the engine crankshafts were rotating counter-clockwise when viewed from the operator's seat instead of clockwise. Therefore, Ingersoll was forced to redesign the mower decks and snowcasters to compensate for this direction change, hence the fact that 4 digit tractors use RH discharge decks instead of Left Hand Discharge decks as you have on your 446.

Sorry to be the bearer of bad tidings but someone had to tell you before you proceeded with this project and then discovered that your tractor wouldn't even move.

If you wish to use a larger pump, I will find one for you. If the pump you bought has not been shipped, then I suggest that you contact the Seller and see if you can work something out.

Thank you, it's better to hear it now, than like you said later. I will talk to seller and wait until the other stuff come's in. The JD stuff fell thru, so I got some parts that were on a Bolan's , and yes the reason behind this project is a FEL, Thanks again John

John,
I thought that you had already bought a power steering set up from a Bolens or I would have told you about the Danfoss units. We have manuals of those units right here on this site.

viewtopic.php?f=25&t=874
No problem, in fact I did buy the Bolens set-up( came today) and then found a new in box Danfoss valve for 149 bucks. After looking at the Bolens which is a Eaton valve with all the ports on the side, I think I will be glad that I found the Danfoss one, due to bottom fittings and especially after pulling the inspection cover in the tower area. Once I get the Danfoss in hand I will think it thru and probably do a little mix of both.

Can`t speak to your custom set-up but as I mentioned this is tight work on the stocker.
At the risk of being " Captain Obvious", it helps considerably if you remove the operators seat and mount first.
99flhr, I have four kid's,and two of them still have little hands :sidelaugh:

P.S. Since this tractor is new to me, I might just do a partial tear-down for a good cleaning & inspection which in turn would really help with space, as I want to hard pipe as much as possible at least that's the plan sitting in front of the computer :thumbup:
