Wiley's jeep tractor

[Sheetanshu]

Hello everyone. I'm new to this forum and just wanted a bit of insight from all those that are experienced. I own a 2002 Wiley's jeep and was wondering if I could modify it and run it as a tractor. I saw a couple of videos of people in the US doing it and also found out that Wiley's themselves made a tractor jeep long ago. According to some basic calculations I did, if I add a secondary reduction after the gearbox the jeep should be able to produce enough traction. So is this possible ? Or am I missing something here a. And any idea why something like this doesn't already exist ? A car or jeep that can be used to plough and till.

Thanks in advance for your response.

A 2002 doesn't have the PTO opening in the rear of the transfer case, and the fuel tank is now in the rear where some of the 3 point hitch mechanisms fit, and it would also block the PTO shaft.

The gearing wasn't reduced in the farm Jeeps compared to others, but the axles were normally geared 5.38 to 1 in that era. About half that now.

Some had the optional 4sp truck transmissions with a very low first gear.

You can get lower gears for some modern transfer cases.

Modern frames are much stronger.

Okay thanks for the info. But I have a few queries :

1. Is it possible to use any kind of jeep effectively as a tractor ?
The farm jeep shown in the links you posted, do they work well ? And can they still be used as jeeps ?

2. Is it possible for me to just use a normal drawbar hitch instead if a 3PTH ?

3. Will the weight in the rear wheels and traction produced be enough for a 2WD jeep to plough effectively on different kinds of soil L

Thank you

No , no , and no . That is why tractors exist .

Sorry to sound like a noob. But why not ? If a jeep can put down the same amount of torque at the wheel, what's the basic differentiator ?

I hadn't noticed where you are. Jeeps (with that name on them. Some people call any utility 4x4 a jeep) may have different drive trains than USA Jeeps.

A 4x4 Jeep is probably as good as a 2wd compact tractor at pulling towed implements. I known several farmers who used them for pulling rakes, balers, harrows, and sprayers. I've never seen anyone plow or disc with a Jeep, except in ads.

A 2wd Jeep would probably tow lightweight wheeled implements on firm ground, but I wouldn't expect more.

It is often less expensive to sell what you have, then buy what you need, than to try to convert something. (as in changing a 2wd Jeep to 4wd)

You have to have BOTH torque and traction.

See this thread, in which an 18hp tractor (I believe someone said) outpulls an 850 hp tractor.

I actually own a Wiley's jeep. But I understand what you mean.

Okay I guess I see what you mean. But in case I strapped on huge *** agricultural tires on to it, would it still not be able to do it ?
I'm sorry. I just dint get why it doesn't work. The components are pretty much the same. And the value are too. There still seems to be a difference. And this is when I'm comparing a jeep tractor to let's say a 20-30 HP Tractor

Read about "doodlebug tractors" for ideas on converting 2wd cars and trucks to tractors.

Okay thanks a lot. Will do.

Another point: Weight. A lot of traction, also known as tractive effort, is a function of weight.

You can have all the torque and horsepower you need, but if you can't hook it to the ground with a combination of wheel size, tread pattern and weight, all you'll get is wheel spin.

You also need to consider the effect of the rear suspension. Tractors have no suspension other than the cushioning effect of pneumatic tires. If you have leaf springs, some of the torque that you're trying to put on the ground to do work will result in twisting the rear end in the spring mounts and "winding up" the springs.

At the least, you'll have wheel hop. At the worst, you break the springs, universal joints or driveshaft.

None of the above is a "deal killer" you just need to think about matching your load to the amount of usable tractive effort you can generate without breaking things.

Yep. We even have that problem with Jeeps and Buggies that we 4wheel with. In extreme conditions they will "axle wrap" the rear leaf springs which causes the rear pinion shaft to point upward. If it wraps far enough you spit out the rear driveshaft, right after you break the Ujoint and destroy the shaft yoke and sometimes the pinion yoke.

Kinda looks like this.




Or this.





Makes the operator have this look on his face......

Just curious...where did you find a "2002" Willys anything?

Check his location.

Check his location.

Interesting...considering that Mahindra (meaning the root company) had one of the first overseas contracts to make the Willys Jeep for the US...

A neighbor has one as /pine pictured. 3pt hitch & pto & 4WD. Very cool. I don't think you'll do much plowing with a 2WD. I remember years ago as a kid seeing jeeps used on the highways mowing. Seen them set up as ditch diggers with a rear "ditch witch" style chain, and a few other "arrangements" that were odd. I think that someone posted one here that had a loader/backhoe set up a year or so ago.

There is a member that restores/plays with those old jeeps, I had to look back to find his handle, "ihfarm".

My Dad has an old 3B in a barn, I'd love to have a 3ph for it. Wouldn't do much good until the engine is rebuilt, however.

I have a Topeka jeep bought off the county- which used a side mounted mower for mowing ditches. the lift for the mower and the mower head all operated off the front of a continetal red seal 4cyl. motor. It has dual 15 inch tires on the back and 4 wheel drive on the front. Large hyd. tank on back end and some serious counter weight hung under the left side of the frame to counter balance the mower. Way under powered for most tasks.
