3016 shuttle diff lock

[sspenst]

Anyone had similar problem like my 3016 where the diff lock lever just flops around? It seems like it's permanently engaged and no amount of turning or holding lever up or alternatively braking left and right disengages it. Makes no noise. My dealer is many hrs away. My choice on that Part. Any help will be appreciated.

Have heard some say there is occasionally something in the linkage that will bind on some models. Typical advise is to follow the linkage down under the floor pan and lube all points.

I can't remember if it is the 3016 or a different model (perhaps someone else with better knowledge of that model will chime in before long), but some the linkage will pass through the upper part of the housing because the pedal is on the left and the actual lock on the diff is on the right. It may be something as silly as a pin that has came loose on the linkage.

Are you sure the diff is actually engaged? In 2WD the tractor should try to fight the steering and continue straight even with the front wheels turned. Forcing it to drive in a circle will also cause one rear tire or the other to slip and is very hard on turf.

I'm positive it's engaged. It's a shuttle shift so the lever is on the right side. There really isn't any linkage on the lever. Lever goes up and down maybe 1/2 an inch at most. And I've tried pushing into a few bales of hay to make tires spin and they both make ruts. I've jacked the rear end up and turned by hand also. Both turn same direction. should turn oposite if lock is disengaged and tires off groud I do think.

I remember seeing other threads about this on the 3016, so maybe do a search and see if you can find them.

Solved my issue. Ended up being a sticky triangular piece under the foot lever that actually works the diff lock. Worked it back and forth a few times but still would not disenage on its own so i installed a spring into the existing hole in that plate then attached it to the seat plate and works like it should. Now whether or not theres a internal spring that came loose or broke i have no idea makes no noise internally so i figured its probably better now than before . I ordered a service manual for future use .

Could you take a photo & Post. I'd like to see what you did to fix.

I have a Max28, maybe 12 hours on it, and the darn lock is a lot sticker than I'm used to on a tractor, both to engage and release. I'm sort of scared to use it for fear it won't disengage.

Sure no problem. Ill try to remember to take a picture after work tommorow. Its not the prettiest but prob better than origional. In the mean time ill attach a pic of what actually shifts the diff lock. 3016 shuttle but prob similar on the max28...

The max28 is set up exactly the same... "super simple design" little more complex on the hydro units though. I do wish there was a bit more there for your heel to press on when engaging.

I will add a quick note:

If you high center your tractor and lose traction, or you find loss of traction while moving in low gear. It can be difficult to set the diff lock because you need to avoid/miss a tree or some other object... I frequently use the turning brakes, I keep the brakes unsecured (flip the lever that binds the pedals together) and use in the event of loss of traction- It works great and has saved me from everything from steep terrain to high centering on deep ruts.

My old 8n has taught me the advantages of using this tried and proven design.

For those out there who haven't tried using it in 2wd, idle up a bit and step on the individual brake while making a tight turn in your yard- it will turn on a dime!

I had a similar problem only mine was stuck to the floor. In following the engagement linkage, I sprayed everything I could see with Liquid Wrench hoping it would seep into things i couldn't see. Seemed to do the trick as it has not stuck again.
