With Manual Locking Differental pedal do you step on it befor letting out the clutch or while one tire is slipping. This is on a Massey 135 Tractor. Thanks, Mark H.

I don't know if all this will fit on here, but this is what my 2135 owner's manual says:

"DIFFERENTIAL LOCK (Optional) The Differential lock pedal, No.2, Fig. 2, is located to the rear of the right step plate and is the tip-up type, wjocj provides additional foot-space when pedal is not in use. Differential lock is especailly advantageous where traction is poor. By deressing the differential lock pedal, the rear axles are locked together so that both rear wheels pull simultaneously, providing greater traction and preventing needless tire wear.

IMPORTANT: FOR BEST RESULTS, ENGAGE DIFFERENTIAL LOCK BEFORE EXCESSIVE SLIPPAGE OCCURS. DO NOT ENGAGE DIFFERENTIAL LOCK WITH ONE WHEEL SPINNING. IF THIS CONDITION OCCURS, DEPRESS CLUTCH PEDAL AND, THEN, ENGAGE DIFFERENTIAL LOCK. THE DIFFERENTAIL LOCK CAN BE DISENGAGED IN SEVERAL WAYS. FIRST, RELEASE THE PEDAL, THEN, (1) DECLUTCH THE TRACTOR, (2) TURN TO THE RIGHT OR LEFT, (3) LIGHTLY DEPRESS THE RIGHT BRAKE PEDAL."

The caps were actually italics Except for "DO NOT ENGAGE THE DIFFERENTIAL LOCK WITH ONE WHEEL SPINNING."

This seems to say to me that if you get into a spot where you start spinning one tire, just clutch and engage the lock and unclutch. It should disengage itself before you do any damage to the differential. I usually do all three of those things just to be fer sure fer sure.

Actually, this thread has been most informative for me, putting to lie the posting about this site being stale:)

Well thank you! Now that I have a Massey 135 I will be posting to learn about this new tractor I have. I do like to know about what I own. Hate to see a Board go stale. Mark H.

My 2 cents is to purchase the Operator's Manual and follow the instructions which it gives. While you are at it, buy the Repair Manual and the Parts Manual. Owning a tractor without these three manuals is a very risky way to go.

I have a opperators Original manual but I did not notice it saying how to you it. I will read it again and see. I do want to get the repair manuals and Big Deans CD disk on the Massey 100 series too. Mark H.

The differential lock is designed to be engaged while moving straight and in slippery conditions only. The differential lock will only engage once the gears are lined up with each other, which is the reason for forward movement. You will also notice that the differential lock will usually not engage unless one tire is turning faster than the other such as in mud. Note - Do not engage the differential lock if one tire is spinning out of control and the other tire is almost stopped because you can break something.

Willy is right... Do not engage the differential lock when the clutch is engaged. It will break the differential gears.....I know cause I did it last year. I had to completely rebuild the rear differential and that costs some major $$$.

So just make sure your stopped and the clutch is not engaged when you use it.

I had the same experience as Mike. But the damage was done BEFORE I bought the tractor. All the teeth were sheared off the differential lock gear. Some of the teeth found their way into the wheel bearing, and trashed them. Don't remember the exact repair bill, but it was in the neighborhood of $1,500 or so.

Hey Mark, Not sure about this type/model tractor but the payloader I drive at the salvage yard has a differential lock and the manual says "DO NOT ENGUAGE WHILE TIRES ARE SPINING", makes sense, kind'a like shifting without a clutch "Grind,grind".

later,dave

Thanks Dave that what I thought, I engaged it once while the tires were spinning and I did not like the way it felt doing it so I thougt maybe you need to push the clutch in first. Just checking, do to I did not want to bust nothing. Mark H.

Mark I have always been told when using the diff. lock is to push down before letting out the clutch and to only use it going forward that you could break a axle while turning the wheels when locked in. That is the way i use my 65 massey Not because i have one but i think that it is the greatest tractor, not to big, not to little. p.s. Your 135 massey is a great tractor too Have fun.
