Differential lock

[k0ua]

I agree with the locked rear making you go straight.
I grew up using the individual brakes to steer but many newer hydro tractors have the brakes and hydro peddle on the same side. Do the manufactures know most humans have only one right leg?

That is one reason I love my Kioti DK35se tractor. The split brakes are on the left side and the twin hydro pedals are on the right side. Yes it has a diffy lock, but I prefer to use the split brakes to slow down the spinning tire and give the other side something to push against and start moving. Usually just a momentary application of the spinning tires individual brake will get you moving again. Less wear and tear than the differential lock.

I see discussion of this on various threads, but what's it used for? What's the purpose? Same thing as a limited slip differential on cars? To keep one wheel from slipping causing loss of drive?

Not quite like a limited slip. When diffy lock is engaged - obviously, the rear differential is locked and power to the rear differential is sent equally to both rear tires. It should be used only under the most "slick" of conditions. Snow - ice - mud and the like. Remember the rear axle is now locked to the rear differential and the rear differential is also locked. There are only two avenues of relief for torsion build up - one or both rear tires slip - something in the rear drive train breaks and relieves the torsion.

Yeah, no friction disks or anything like that when we say differential lock, we mean LOCKED as in metal locked to metal. Both left and right axles locked to the ring gear. NOT limited slip, LOCKED like a "spool"

What's it used for? Lets say one rear tire is in the proverbial mud hole, the other tires is on concrete. The tire in the mud hole spins, the other tire does not even move. Press diferential lock, apply some power, and out of the hole the tractor comes. It has to, it has no other choice. OR you could apply some mild brake pressure to the brake on the side of the spinning tire, and then thru the differential action of the spyder gears it will apply torque to the bevel gear on the other side, and since the bevel gears are affixed to the axle, then that axle, wheel and tire will move. Out of the mud hole you come.

Using the split brakes is just another way of getting you out of that hole other than differential lock. Just another arrow in the quiver.
