YM240 Diff Lock Repair Question

[Maynah13]

Ahh, that sounds like a possibility. There's no spring on the outside. Am I correct that I must remove the ROPS and PTO to get to this?

Thanks,
Robert

When I raise my pedal up . It bounces back down against a pin that sticks out just a little.Can you see the pin that the pedal would rest against in the down position ?? Like I said mine isn's spring loaded it just lays there waiting for the foot to press it

I recently bought another tractor, a John Deere 750, that also has a differential lock. As a matter of fact, that tractor was made by Yanmar also. It's diff lock pedal stays up unless I push it down. Then it's like pushing on a spring. If I let go, it springs back up. I assume the YM240 is supposed to operate in the same way? The JD has a stop screw to prevent it from being pushed down too far, but the shaft on the Yanmar doesn't. I took a photo but have to find a way to post it...

Here's a photo of the lever:

Mine looks identical to your photo, except it springs back up.

From what I'm seeing, the design evolved over time, to lessen the chance of catastrophic failure if used incorrectly. Mine is the early design. It's difficult to say for sure but I believe mine was built around 1977 (S# 000723)

I'm still hoping someone buys it as is, but if I can't get a reasonable price for it, I may have to repair it. Even then, I just had one buyer tell me he couldn't get financing because the bank said it was only worth $3500, and that was only if it was in perfect condition. I see YM240's going for way more than that and many don't have the ROPS I had installed. I'm asking about $500 more than that, BTW. I just put a lot into it- radiator repair, hoses, filters, belt, etc., and everything is in good condition, except for the diff lock. I wonder if I'm still asking too much. I'm already going to take a big loss on what I have invested and spending the time to tear it down will just put me further in the hole.

*UPDATE* I sold the tractor today, so it's now a moot issue. I did pass on what I've discovered to the new owner.

Thanks to everybody for your input!

P.S.- I'm going to be VERY careful if I use the diff lock on my JD 750!

I use my differential lock quite a bit and I've never had a problem. I could be wrong but I wouldn't worry about babying it.
