Need advice from anyone.Don't know much about John Deeres. Found a 420U (SERIAL # 81421)with a "Henry TS4" loader with 3 ft. bucket downward pressure and power steering. Power steering does not work. What could be problem? Tractor looked like it only had three forward and one reverse gear. Is the power steering and loader legitimate equipmment or is this a homemade special? Would this tractor be a decent all around the hobby farm on rocky hilly new england slopes? What's it worth? Thanks for any comment or help.

Check out htis and see how it compares. This is a 420W which has the final reduction drives inboard.

If you don't want it, let me know. I have a 420U with a Lord loader, but no power steering and would like to find a tractor with the power steering option. I have a 6 foot snow bucket on mine and use it all the time around the place to move my snow (New Hampshire) carry my firewood, lift heavy stones and as all around strong helper that doesn�t complain. I also have a 40C with a Lord loader so am partial to the 2 cylinder verticals. The are easy to work on, parts are in good supply and they run good.

Some advice: Check the tires and tire size. 26� tires are almost impossible to find, either new or used so replacements can be a problem. The electrical system is six-volt and works great, if everything is in good shape. Mine will start to well below zero. I did change the pulley on the generator to a �� smaller size to increase the RPM and charging rate. I run double ring chains with loaded tires and most of the time carry a heavy weight box on the three point hitch. Also have a Woods 5� chipper that runs off the PTO and works great.

Value wise, if it runs good and is in good shape, they go for at least $2500 around my area. I would pay that or more for a decent one. Check the loader for cracks and make sure that it is not bent.

If you go any combine junk yard you can find
26" tires cheap.They were once a standard size
on combines.I've seen whole combines with almost
new 26" rubber go for under $100.00.They used 3
types of PS on 420 tractors.The first used tractor
hydraulic,the second had a seperate PS pump,with
a round reserve tank,and the late style used a PS pump,much like a car.A car pump will fit and work on these.

Need your opinion. Turns out the power steering on the 1956 "all green" 420U I'm thinking of buying is internal, using tractor hydraulics. no external pump. Dealer says problem with power steering is relief valve (the wrong one was in it) and he's ordering another one. Does that sound right? Is that kind of power steerring better or worse in terms of lasting and use? Is a Henry loader decent?
Thanks for your help. I'nm going Friday to look the tractor over.

Ray,
Do you mean a car pump could replace the existing power steering on ALL three kinds of 420 setups or just on the latest models. The one I am looking at is the second kind (the kind with the round reserve tank.
Thanks.

Yes, a car pump can be adapted to the one's with
a seperate pump.They actually work a lot better
than the JD pump.

thanks for your advice. will let you know if I don't buy it. It does have 26" tires. would that be a deal breaker for you?
do you know if there are after market power steering parts? any place I could call?
I'll know this weekend ...they want 3500 with loader.

BTW parts interchangability between 40/420/430 is good and even some "M" parts fit. Mine does not have a serial number tag, but it is either a first year 420 or a 40 with a 420 motor. I have checked several so indicators and all says first year 420. but the motor is later as it has the oikl fill and dip stick in the same hole. I am always looking for clues and would welcome any more hints as to how to date exact year/model on a machine without the tag.

CPeter,

If you have Delco-Remy electrical components and you believe them to be original, post the serial number and I can decipher for you (it is actually a date code). It won't tell you when the tractor was made, but it had to be made sometime after these components.

Don't know about PS parts. I have visions of adapting a pickup truck unit to mine. Price is high unless the loader is in real good shape and the tires and all else are above average. Have seen several on EBAY for under $3000 recently. New rear tires and tubes will run $800 plus mounting, so keep that in mind. This is as nice a JD in this size for you needs as you will find. The "U" series has the final drives turned 90 degrees to the rear to lower the center of gravity and extend the wheelbase. This makes it a very stable machine, especially if you put the rear wheels out to the maximum width.

All this just confuses the issue. BTW this is a 29 HP tractor and has good pulling power at low speeds. Second and reverse are opposite each other in the shift pattern and you can use them like a shuttle as they are geared about the same.

CPeter, I have a 430 with JD loader and wide bucket like yours and also no PS. Not sure how you are thinking about using the pickup ps unit, would be interested to know. I have noticed that the 95 combines with ps used a "actuator" in the tie rod to activate the power steering, think that could be adapted to one of these tractors. Early 50s fords used the same type system but trying to find one of them would be like trying to find a used ps unit for one of these tractors. If your part of the country has old 95 combines you might take a look at one with ps and see what you think.

Thanks. called JD dealer' they don't make the PS pump or cylinder anymore. Called two east coast junkyards-struck out. Both are not aware of aftermarket possiblities. tires are 60percent and loader is good condition. tractor is actually in connecticuit. So I guess the power steering is the main question as to buying it. without the power steering I could hardly turn the wheels. Thanks for the support and I'll let you know what happens.

I have the whole tie rod PS setup off an early Ford Mustang that I was going to try and adapt to this tractor. I could never quite figure out how to fit it in place. This unit includes the pump and cylinder assembly. Not many combines in northern New England, so the tire issue is still a problem.I checked with with Nash's in Colebrook, NH(on the Canadian Border) and he did have a mismatched pair, but the 400 mile round trip to look at them wasn't in my plans.

On the PS unit. I thought about fabricating a new pedestal to hold a truck steering box and save the original unit so I could put it back if I wanted. Only issue is a shaft extension to go down to the pitman arm.

The 420U you describe is a 1956 and is an all-green, it has no yellow stripe. Chances are it's a 4 speed...4 forward with 1 reverse. The later versions had the 5 speed with a yellow stripe. I have no idea about the bucket. The utility would make a great hobby tractor. They are easy to get on and off and are universal. As Brandon mentioned, the early model 420 is alittle more valuable than the other 420's because of the numbers produced.

BMeyer is right, it is a 1956 model-the first year of production.

I'll try not to type when tired!

Power Steering was an option for the 420s, I think I've heard that getting power steering parts is a problem, but I've never had to look myself.

Henry backhoes and loaders are pretty common on the small Deeres, they are from an outside company (although, they may have been approved by Deere, don't know).

That 420 is from 1958, an "all green" model with no yellow stripe. They are more valuable than other 420s, but I don't really know how much. You should have more than three speeds, but I don't know much about the 420s to say if it is just cobbled up or something else.

Good luck,
Brandon
