You don't say the make and model of the tractor. It makes a difference. If you possibly can, get the FACTORY service manual for your tractor; it will certainly show exactly what to do.The earlier posts cover what to do pretty well. I recently split my 4 cyl Ford 4000 row crop. I followed the manual and didn't have any problems. You certainly want to do it on concrete, if at all possible. Here's the steps for my 4000: 1. Drain out the transmission, axle, and hydraulic reservoirs. 2. Shore up the front end of the tractor with some sort of cribbing so it won't fall over. 3. Put a block under the BACK end of the engine oil pan. 4. Unbolt the steering pedestal from the transmission housing. Hook an engine hoist or chain falls to the steering wheel and jack up the pedestal until its free of the transmission. 5. Put a hydraulic floor jack (with wheels) under the transmission. (You'll probably have to add some blocks to get it high enough.) 6. Disconnect anything that connected between the two halves. Electrical wires, hydraulic pump manifold, etc. 7. Take out the bolts that hold the front half to the back half, making certain that both halves are fully supported. 8. Roll the back end straight back, and your done. 9. On reassembly, the tricky part is getting the transmission shaft back into the clutch. It has to be aligned just right or it won't go.
