how does this work?

how does this locker work? this is a bolens selectable locker:

That's not a locker, that's a whole dang transaxle. That said, MANY compact and fullsize tractors have a differential lock, often actuated by a pedal. There's a few different systems out there, but they all basically boil down to a mechanical coupling that overrides the differential action of the spider gears.

Parts 69 and 68 slid together, and lock axle to diff carrier.

I believe parts #11 and #8 create the locking diff. Would be a good concept for a modern transaxle!

I'm not exactly a pro at reading exploded views, but it looks like what Red said is what actuates what Stretch said.

thanks guys! I was wondering how it locked, I couldn't figure it out from the picture

When all else fails, read the manual.

The pin that Red refers to is actually the freewheeling pin. It is pulled to disengage the wheels from the transmission, and allow the tractor to be pushed. 8 and 6 are locked together with the 11 pin. 6 is the wheel hub.

Notice how it is a solid axle(53), through the diff(67)? Huh?(that's what I though anyways!) The left side hub(54) spins on that solid axle(53), and is driven by the left side spider gears. You lock the rear by locking the left hub,54 to the axle,53 that it can spin on.

Part 45 is able to be turned, and is actually an adjustable limited slip. You can tighten it, and it locks the hub and axle with friction washers. It's not actually a locker, but can be adjusted tight enough to give almost locker action.

The parts(67, 69) I was looking at lock the solid axle to the right side spider gears.

This is what doing drafting classes, and doing journeyman machine repair work gets you....

It may not be a friction washer, it may use a tapered cone to lock.

Here is the pic, with the parts listed.

that is interesting....... I wish all of the trannys where made unlimited slip like that

The correct answer to your question

"How does this work?" is....

not at all exploded like that!

Yeah, that's a great little feature! Nice top loader transaxle too. They don't make 'em like they used to!
