Bet this is hard to steer

[RED-Z06 2,220]

Found on marketplace...418-A with a loader, bet that is a handful with a few hundred pounds in the bucket

It would be some tolerable as long as you were moving the tractor while steering. 

 

Definitely a good candidate for reduction steering.

A weight box behind the rear axle would help.

Agreed. Our backhoe is a great counterbalance.

With those "forks", it's looks like a nice lawn chair carrier.

Wish these tractors had power steering, the hydros had the auxiliary outlets, there's room for an orbital valve...and they were already priced around the cost of tractors with power steering...

@Bow_Extreme has a power steering prototype 520H.  He is very knowledgeable in the way it works!

Couldn’t agree more!

I know a little…lol.  The tractor shown would be well worth picking up.  I would opt for gear reduction steering w/swept axle and the 8” wheels.  From there I would put a set of tri-rib’s on to manage the steering that much better.  I have two steering reduction kits available and one that is complete with everything from steering wheel to front wheels.  I haven’t yet posted but I will.

There's a very old thread here, but there are some pictures of the dealer kit for power steering, as well as a couple homemade versions.

I assume these are still NLA, but they certainly feed the imagination should someone get bored.

I own the prototype 520.  They were not actually factory kits.  They were designed by a contract engineer, to Toro, on his own time.  He showed Toro but they were not interested.  He did build a number of kits and sold them to local dealers.  I know him personally and he’s a wealth of information and knowledge, regarding the tractors, decks, and other Wheel Horse items.

Regarding powersteering on a Wheel Horse (or other small vehicle for that matter) there are electric powersteering units one could use.

Some of them have a motor on the steering rack and others on the shaft that leads to the steering rack.

Seems easy enough to adapt, even to vehicles without hydraulics.

If I were going there, I'd look to a unit that leaves the current tie rods and lower steering shaft in place to preserve the geometry of the steering.

Agreed. The unit with the drive-motor on the steering shaft would also be my first pick.

Seems to be as easy as giving it 12V DC and you're off to the races.

 

Might try it on my 512-D. Sure could use it with that heavy sweeper on the nose.

Have a look at my two threads on the subject....apologies, I have tried to 'quote' them here but without success.

 

First one is:

Wheel Horse 500H Series Power Steering Conversion

This was for a 518H..ie already has hydraulic power but it would be relatively easy to add a belt driven automotive pump and tank for the manual transmission tractors.

 

Second one discusses the geometry issues @Handy Don refers to....there's a simple solution: 

Wheel Horse 500 Swept Front Axle Geometry Correction

 

 

There's really insufficient room in the dash tower for an electric system, at least, not without considerable butchery. I'm really pleased with my conversion, it has transformed the machine.

 

Hope this helps.

The power steering thread includes step by step detail. It looks complicated, but in reality, is quite straight forward.
