My brother is rebuilding the transmission and PTO end of a four wheel drive Satoh Beaver 3
tractor. This is a small 3 cylinder diesel tractor that was built by Mitsubishi in the 80s.
This particular machine spent most of its life in a barn. But the clutch often rusted to the flywheel. So we would break it loose by starting the tractor in gear, pounding on the clutch pedal, and occasionally chaining the tractor to a stump. One of those methods would eventually break it loose. But it developed a clank under the transmission.
So
Josiah started tearing it apart at the beginning of the year. He has found several gears that are missing teeth. At this point the transmission and rear end are almost completely disassembled. The following is a photo dump in case it proves useful to anyone.
