Backyard Mechanic Brains Needed

Please help. I need to put a clutch in line between an automatic transmission and a rear end in a tractor and truck pulling eliminator. When a tractor pulls me down the track, I want to stop the automatic transmission from running backwards. Is there an easy fix using something like a 12 volt electric clutch on the shaft like from a chopper head or a combine head or something from a junkyard? Thanks.

What about a four wheel drive transfer case. Will just bolt to your auto or will have to change to a 4X4 auto and transfer case. Late models are electric. Early ones use a lever. just put it in Neutral.

This may be a stretch but fire trucks (some)have a clutch to hook the drive shaft to the water pump and bypass the rear end.

Use a manual trans with cable or hyd.shift to operator platform also this will give you a reduction for soft tracks 6188304992

Thanks. All good ideas so far. What's the best way to add a short (I don't have a lot of room) four wheel drive transfer case that I can shift into neutral. It's just that I don't want the extra weight and mass to bounce around on the end of my transmission. I only want to add a neutral.

What size axles have you got under the sled? A lot of us use 2 speeds and machine one side off so you have neutral/low or high.

Will ya ever need reverse in the automatic?
If NOT, then mebbe a simple overrunning pto sprag clutch would woik?
YMMV
Void where prohibited by lawr

use a pto end out of a farmall m or something shorten down shaft and weld on what spline you need to run into trannsmission lock in or leave in newtral with simple small rod or lever to move rod on a pivot to lock it in?

Just saw the ofset case with the chain in it off and patch the hole up. While you are welding a patch on put a 3/4 pipe plug in it so you can put a little oil back in. Not pretty but will work.
