Homemade tractor

I have an Isuzu 4x4 small pickup that is no longer roadworthy. Anybody got any ideas about making it into some kind of a tractor/woodsbuggy? Low range is really slow so bigger wheels for clearance might be a start.
 
The options are many. Tractors are much harder, They must do things and be regulated in speed. Suspensions are not allowed, and do not work well.
Make a buggy out of it.
Ridged schedual 40 pipe. Measure everything while it is still whole.
Plann for adapting as much as possible. use the floor pan and pedal systems to simplify setup. Make a roll bar, and seatbelt!!! JimN
 
You could add a governor. They make a belt driven governor for such purposes. One of my tractors has a foot throttle and a hand throttle. The hand throttle uses the governor, the foot throttle does not. Both are handy at different times and tasks.

As for tractors not allowed to have suspensions, many a European tractors and several top end US makes DO have suspensions for better and faster riding.

You are correct they are high end, and engineered. They also have traction. To do a real tractor job, it will require massive reengineering. Buy a tractor make a toy. JimN
 
The person welding it together, I am no purist, nothing Further from the truth. It is just easier to make a dootle Bug than a usable tractor. I have had many of each. including what many consider a vehicle tractor CJ3B and even it is not stock. JimN
 
And in some situations they get better traction because of the suspensions, especially at 30 mph while spraying or moving from field to field. Otherwise a tractor with no suspension components depends on the flexibility of the tires and they aren't so well controlled.

Back about 1950 my dad too pieces of a Model A Ford and a new Wards/Wisconsin engine and built a garden tractor. It mowed well, plowed, and harrowed decently and pulled a jeep trailer for hauling leaves and grass clippings for a good 50 years. I have it now.

The parts of a 4x4 would work there too, though at the low speeds for a tractor, the engine wouldn't be heavily used.

An uncle of mine about that some era built a walk behind tractor with a 4 cylinder motor cycle engine for power. It was hard on him using it but he has survived it.

There is a huge thread by a guy on Tractorbynet.com that's been goink on for over a year. It' like 20 pages long. He took a small 4x4, I think a Suzuki and is working on converting it. I stopped reading it as it got too long. But it's full of useful information. Here's a link to it:

Hope this helps some.
 
What do you mean, no suspension allowed. Is this a federal law? I think I saw a new JD the other day with hyd front suspension. Wasn't a lot of new tractors homemade-homebrew. Don't Euro tractors have suspension?
 
I later thought likely that is what you meant. As mentioned, many good SP sprayers have been made out of truck or even car components. Often, whether you choose to call the finished product a "tractor" is the question. Usually the best of these units are built by someone with lots of time (and no worries about getting paid for it). Mostly need some after fabrication tweaking and no two end up the same.
 
Something I'd like to try myself someday.

I would leave the suspension. Might want to shorten up the wheelbase to make it more maneuver. Skid plates in critical areas and shields of some sort to keep grass and such from wrapping around the driveshafts would be a good idea. You'll probably need to add weight for traction.

I wouldn't worry about adding some sort of PTO, leave that work for a real tractor, but a hydraulic system with remotes and 3pt hitch on each end would make it a real handy light duty chore "tractor".
 
Bernie, I am in the same situation...I have a deisel isuzu 4x4 that I was going to use to repower my Satoh but then started thinking along the same lines. issues- Independent front axles suspended by torsion bars. If this thing had a straight axle on leaf springs I'd chop it up in a minute. Mine has huge frame rot, so simply shortening the existing frame won't work for me. Come up with a work around for the front axles and you're in business
