rmiller, the early tractors used the AA3032R Shaft Cranking,, the later tractors used the AB 3580R Shaft Cranking/ With Key.. There was also some variants on that basic cranking shaft that were longer in length to allow hand starting with mounted equipment. Basically they work better if you have an old or extra steering wheel laying around or they would require removing your tractor's steering wheel.. They were just a short stud shaft with a machined shaft & key on one end that fit the removed steering wheel & machined angled slots on the other end that would fit the L/H end of the crankshaft or a flywheel adapter.. I remember using those when I was younger & chasing that steering wheel out across the barnyard as the tractor would fire & grab that steering wheel & spin it out like a rolling tire that fell off a car.. I have a picture here somewhere but can’t seem to locate it at the moment [will post it later if I find it] As far as compression releases, some of the later tractors have cylinder drain plugs up under the bottom on the cylinders & those plugs can be removed & petcocks installed in their place. You ask.. Quote: --“ Are there other ways to hand start them?”
--Sure, you have the option of pull starting them with a truck or other tractor, jumping them from a vehicle with a suitable voltage battery, using a battery charger on the dead battery, or a favorite of mine & that is parking the tractor on a steep hill then roll starting it when you want to use it.. Then there is always the fun option of using a flat belt & another tractor.. [lots of options].. As far as being available, yes, you can find them in the junk piles at a lot of local tractor shows, there are a few places that are making repos for sale, they come up from time to time on Ebay, & I’ll bet if you posted a wanted in the want adds here someone would respond.. Just be sure give the specifics on your tractor year & type. Clooney
