Diff lock operation

[Trkrd]

Since owning my 240D I have only used the diff lock once or twice, mainly just use 4wd in the slippery stuff. With all the precipitation here lately things are getting quite sloppy and locking the diff would be a little extra insurance when travelling through this greasy Arkansas mud. My question is should the lock be engaged at a standstill with clutch in? or when rolling?

Standstill.

I usually engage mine when rolling, it won't easilly engage until the rear wheels turn at different speeds. It should be spring loaded to pop out when you lift your foot off of it, but it might not pop out until you take the load off of the diff.
The diff lock should be used while going straight only unless it's really sloppy, 'cause it dosen't allow the rear wheels to turn at different speeds in a turn.

Hmmm......1 vote rolling, 1 vote standstill

It won't hurt the diff either way, just don't try to engage it while spinning 1 tire in high gear and you should be fine.
You can try to engage the diff at a standstill, but it probably won't "go in" until you start moving or loose traction anyway

My vote C doesn't matter.Why would anyone want to ingage it if your moving. The only time I did I was stuck spinning.Not moving.
But for it to lock in you have to move spin the gears. Trying to move

The few times I tried it was rolling. It (the pedal) would not go all the way down at first so I babied it, keeping just a little pressure on it until it engaged. Does this sound right? I just like to have it locked in anticipation of the nastiness I'm about to go through. Better to roll through than to start spinning and get stuck. IMHO

Mine will not engage until I spin the tire just a bit. Slowly. I sheared off all the differential bolts on my JD 750 by engaging the lock whilst the tire was madly spinning. It took 19 years of this abuse but the tractor stopped moving one day in 2wd.

I suspect Danny read the manual.

I suspect theres a little more to truth than a manual.
