FYI Add on electric steering......

After I added electric power steering assist to my '38 Chevy street rod I realized how easy it would be to add assist to an older tractor.All that is required is a unit from the salvage yard (This one is from a Chevy Cobalt) The unit needs to be installed between the steering wheel and the steering box so it is necessary to cut the shaft. You will need to fabricate connectors, you can use the shafts from the donor car. After the unit is installed all that you need to do is connect 2 wires to the battery including a 50 amp fuse. The third wire goes to the key switch. I paid less than $50 for everything I needed at the salvage yard. The tractor needs to be 12 V.

What a great idea! could save a lot of hydraulic plumbing issues and be retrofitted to a great many tractors or what ever you have.

I think this is neat concept, do not know how large of alternator is required to keep up, please keep posting.

50 amps x 12 Volts = 600 watts or just a little under 1 HP.
 
The 'Tractor Doc' from RedPower and Green Magazine wrote a couple of good informative articles about electric power steering for tractors.His 'prototype' was a Farmall A that his wife used as a 'lawn mower'. He even put out an informational packet outlineing and detailing the whole proccess.I ordered it,cost ten dollars. I have yet to use it,but electric power steering is in the future for me.
 
It would for sure require an alternator conversion, and a higher amp alternator is easily doable.

I think it would work on most applications that didn't require a demanding steering application. It would certainly work on most hobby tractors, mowers, etc.

But I can also see it wrecking some of the more fragile steering gears, like N Fords or T Fergusons and trying to use it with a loader. Not something you would turn loose with hired help.
 
I think the Saturn Vue was about the first car to use the electric power steering. Probably many more do now. I see one in the future for my sectioned '48 Hudson, but first, have to get rid of the 3 on the tree shifter (shift rod going down the steering column doesn't allow room for the power steering unit). Hoping to adapt a T-5 overdrive 5 speed manual with floor shifter, but if that's not possible, an overdrive automatic.
 
The steering motor draws maximum amps only when the wheel is being spun fast and the tractor stopped or moving very slowly. Under normal conditions it will draw less than 10% of maximum amps.

Your typical tractor alternator - with the battery handling brief surges - will carry the load just fine.
 
There is an outside controller available to supplement the computer in the car that varies assist with speed . You need assist when turning to park or at slow speeds but not so much on the highway. The computer in the vehicle takes care of that.......
