These were both tangled up in the pile of parts to the B I drug home? Any idea if they actually go to it or just happened to be there. The B has electric start and I did not see a place for this crank? He said he used to have an A, I wondered if maybe the crank went to the A, but the A started on the flywheel not with a crank to my knowledge. Also got the good news that back in those woods he has a JD 2 bottom trip plow as well. Im goona go back and scope those out, try to snag them as well. I am sure I will have many other half assed questions just like this one so please dont beat me up to bad, Thanks for any input you have.

Photos look OK to me unless the middle one was supposed to be the whole piece.
I've never seen a hand crank J.D. that wasn't turned by the flywheel.
Maybe an L, or M, or an older diesel that the pony motor was cranked by hand.
I never was around one of those models except shows, and never paid attention.

I would not use that crank. There are no beveled areas to push the crank out of the engine. Maybe its a window blind crank for a overhead awning. Otherwise it is like the crank on a landing gear.
I was about to post the same thing. Not sure that's a crank handle for an engine.
No way to push it away when the engine starts. Should have an incline on one side,
or a pin that fits the groove and incline on the pulley.
Never seen a wrench like that either, will be interested to learn what it's from, if anyone knows.

My nebighor has a Ford model A and the crank that starts that car looks identical to that one that is in the first two pictures

just a thought on the crank safety - long time back one of the tank trucks I worked on had a crank handle similiar, no kick out ramps, on the aux pump motor - the shaft itself had an overrunning clutch to keep the crank from becoming a weapon when it started, although the kick back if it back fired could still really do some damage to hands and wrists

sorry can't help with identifying the pieces

About what size is the wrench?
Looks like a brake bleeder wrench from here.

there were some tractors that had a stub shaft that went through a casting in front of the crank shaft, I can't remember what make they were, not John Deere. the nut or bolt on the end of the crank had the tapered overrunning slots and the stub shaft had pins on each end . If it didnt have the floating handle, I would say that it might be used to bar the JD engine over for valve lash setting or what ever, electric start late AR s have a pin thru the end of the crankshaft that something like that could work in.

Looking close at the crank; bout 2/3 of the way back theres a hole; can't tell if its all the way through both sides, which could indicate the crank was mounted semi permanant. Is it possible the handle was used with one of the various types of lifting devices made during its time?

It is why I thought it may have been a landing gear crank. Todays cranks are bent pipe with 2 slotted plates welded on the ends.



I did see on the crank there is sufficient wear just behind the socket suggesting that the crank was operated in a hole rather than a bearing for an engine.

I was looking everything over and there is a place in the center of the flywheel to put a crank I am wondering if that crank does go to it and maybey there is a chuck that fits in the end of it. I have been looking at other handcranks and some of them are like that. My oliver hand crank is one solid piece but from what I have seen some cranks have a chuck that fits in the end. There is for sure a place for a hand crank in the center of the flywheel, tapered and all. I have a feeling Im just missing a part to this crank

Ok on my 49b and also model 70 you have two stay bolts that hold the flywheel in place; as is obvious the flywheel is designed for minimum expansion. I have built a series of wrenches to keep these tight.The ones that are on the hand start A's are 1&1/4 inch Also theres a large low torque type hex nut that fits the threads on the crank shaft of the 49b and model 70 as an added safety measure.That parts not used on the hand start B or A. Now i can see using this handle to hold the engine in place while tightening up. But without some missing parts being found no way would i use this tool to turn the engine over with any possibility of fuel in the cylinder. That is if this does turn out to be something Deere designed

There sure is some potential in what You are saying; and i'm inclined to think also if that's what it was designed for that it would be aftermarket. The two old timers that coached me on the hand starts never mentioned a tool like this. Of course while they were alive i pestered them to no end on other models. ;)

Your B can be started with a Hand Crank...thats what the extra piece is bolted to the flywheel for....its a John Deere piece. Not sure if thats the right crank handle for it though.. Most of them for the two-cylinders was a steering wheel with a stub on the end to fit piece on flywheel. The wrench looks like a flywheel wrench.
