On level ground and with equal "footing" under both tires the differential lock really won't do anything to improve traction since both wheels can deliver the same amount of torque to the ground. In these conditions slippage will be virtually the same on both wheels anyway so it won't do anything to save on tire wear. The benefit of the lock is when you want the wheels to pull unequally by being able to apply more torque to one over the other. When unlocked you can only deliver as much torque to both axle shafts as what the wheel with the least traction can apply to the ground. In operations like in-furrow plowing a lock is a big advantage since the more lightly loaded land wheel has less traction available and thus limits the torque potential going to the furrow wheel. The same situation would occur if one wheel is in the mud and the other on dry ground.
When running my FIL's 7230 Magnum I occasionally use it in rough conditions to help the tractor track straighter but that is about it.

It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
