I ain't got a clue what kind of tractors you're talking about. I'm putting power steering on my old 1855 Massey Ferguson using the steering cylinder&control valve&steering shaft off of a parted out 420JD. I'd think that with a little fab work it could be done on most tractors with a hydralic system on them.

It's a Cub 982 Super Garden Tractor,17hp.Kohler,54" deck,hydrostatic. It's a hard steering tractor when moving and when sittin still it takes both hands,could be my bad shoulders,but I don't think so . My old Cub low-Boy steers really easy compared to the 982.

The power steering cylinder is off a Cub 1810,and I need to know if my 982 has outlets somewhere on the hydrostatic for the power steering hoses.

OK, you just bought this tractor and don't really know it's past. Have you raised the steering axle off the ground and tried turning to see if it turns free when unloaded? If you have any steering components that are on the verge of seizing or locking up, you will find it somewhat difficult to turn even unloaded. With the steering axle off the ground you should be able to turn the steering wheel with your little finger. With the steering axle off the ground you should be able to grasp either of the front wheels and turn the steering from lock to lock also. If you can't do either of these, you probably have some part of the steering system trying to seize. Check the king pins, tie rod ends, drag link, and the steering column bushings. It may well be necessary to separate or isolate steering components in order to confirm which component is "binding". Another thing that can (but rarely found) cause "hard" steering is a differential with locked up side gears and spider gears. Have you ever driven a farm tractor equipped with a differential lock? If you answered yes you may recall how the steering goes to blazes if the differential doesn't unlock when you let up on the actuating pedal. That condition will not affect the steering effort on a parked machine so I really doubt it is your problem since you say it is hard to turn when sitting still.

Unless this machine has some hydraulic cylinders already operating in some function on this tractor it probably CAN NOT operate hydraulic components unless it has a separate but unused hydraulic pump in place, or if one can be added. A hydrostatic drive unit is not a "tappable" hydraulic system.

The hydro transaxle IS the source of power for the two lifing cylinders on my Kubota G2160 - Plus I have a spare servo available on the transaxle for a third cylinder as some 2160's came with a power dump cylinder for the grass hopper and mine did not

That said, my machine has electronic power steering ;-)

That Kubota electric motor driven, electronically controlled P/S set-up is about the niftiest thing I've seen as to how to get it done. As to the hydrostatic drive also being able to "out source" hydraulic pressure to operate hydraulic cylinders: I'm not surprized since the tractor was designed from the beginning with hydraulic operated cylinders as part of the standard package. I would be very surprized if it was built with hydraulic outputs "available but capped off" and Kubota didn't offer anything to use them for. I wonder if Kubota's pump for the hydraulic cylinders is a separate pump from the pump for the ground drive portion of their hydrostatic transaxle but both pumps share the same oil reservoir?

This is the largest red Cub Cadet, produced by IH and later by MTD after the purchase of the CC line, but made only in late 1979 and 1980. It is a rare collector's item as few were made. It is powered with a 20 hp Onan engine. Some were sold with a hydraulic lift three point hitch, and with a power take off shaft out the back. Some were also equipped with hydraulic ports in the front and independent brake pedals for the rear wheels disk brakes. All had hydraulic lift for their 60 inch mowing deck.

They have unique steering and are the easiest to steer I have ever seen, without power steering. Correct yours and you will not need PS. I have one, as I described above. It is a joy to own and operate. In good condition it is worth $2,000 to $3,500.

The Onan has been reblaced with a KT17. It has the dual brakes and rear PTO. I will check for binding in the steering,but it has been well taken care of.Maybe it is just me!

I want to replace the engine and add 3 point.The paint is new and shines and it's a very clean tractor,the metal is all straight. I had been looking for a Red 982 at a good price. $1324.00 not bad price,right?

I have the parts breakdown on the Kubota HST and it appears there's only one pump - Shaft driven from the engine. It's an incredibly tough HST and the tractor (~1200 pounds with the mowing deck) will easily pop a wheelie if you stomp on the pedal with the engine much above an idle

The extra, unused hydraulic servo on mine was used on similar models which had a large bagger mounted on the back - They used that servo to hydraulically dump the bag

I plan to ise it as a hydraulic top link for my 3 point hitch

I'm not privy as to how the power steering actually accomplishes it's magic . . . . but it's quite a system - You can drive it all over with one finger

Well I've not had the steering drive motor assembly in my hands but the picture of it gives me the impression that it is like a "rack & pinion" steering gear but instead of having hydraulic "boost" it uses an electric motor to assist in moving the "rack" gear. It probably uses a "spring loaded to center" micro switch/sensor controller unit built into the pinion gear assembly to activate the drive motor when you turn the steering wheel. It also must have some computer control unit as Kubota says the system adjust the steering in accord with ground speed. That implies a speed sensor and at least a micro processor. It would be nice to see a technical drawing of the steering layout and components. As to the pump in the HST, even though it appears to have only one pump, is it possibly a tandem pump? That is, one pump body that actually has the characteristics of 2 separate pumps? One section for HST drive and the other section to provide hydraulic power for cylinders?

The steering rack has a large electronics box attached to it, so you're probably right that it has some 'brains' to go with it. I need to look into the centering feature because mine tends to creep one direction if you take your hands off the wheel . . . . probably just an adjustment
