There seems to be some interest recently in one of my projects so I thought rather than derail someone else's thread I'd start a new one.
I have a 1945 Farmall H that I put T-20 crawler tracks on with my students back during the '05-'06 school year.
To answer some questions:
The H is complete. I could take the undercarriage off at any time, put wheels back on the axles, reinstall the steering components and have the H back as it was when I purchased it.
The tractor steers by differential braking. The original T-20 control levers are mounted to the seat frame and are linked to the brakes by 3/4" steel rods. When you pull back on a lever a brake pedal can be seen moving as the brakes activate but if you step on a brake pedal no movement is transferred back to the lever. A slot in the connection prevents this.
The 2x4's mounted on the tracks are made of HDPE plastic. There are 29 of them on each side. 4 holes were bored part way through on the bottom of each to clear the track plate bolts. 2 holes are all the way through to bolt them to the track plates and each of those holes in counter-bored for the head of a carriage bolt. 464 drilling operations in all! Actually 480 since I made 2 spare blocks with remaining material.
The blocks do help to keep the tracks from tearing up the driveway and the road but do limit some of the traction in the dirt but since it really wasn't built for pulling a plow that's ok with me.
Here's a close-up of the decals I made for it.

Today's Featured Article - My Ford Golden Jubilee - by Troy Estes. This article is about my '53 Ford Jubilee and a story that starts with taking the tractor to my brother's Starter/Alternator Rebuilding shop for a wiring fix. The generator was shot as well as all the wiring. I dropped off the tractor expecting a transformation from a 6 volt to a 12 volt system utilizing the original generator housing, and a total rewiring of the whole tractor. The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that�s wha
