Smokeydog,
If my memory serves, the M59 has 3 modes for driving wheels. Unlocked, where I believe a single rear wheel is driven. Locking of front and back, where both front wheels are driven with a standard differential between front wheels and the existing rear wheel is engaged. Locked and manual differential lock is engaged by stepping on then both rear wheels are locked together and both front wheels are also driven but not locked together.
Consulted the Workshop Manual for clarification but was not able to find any details about driven wheels and the modes.
When the rear wheels are locked then steering is ineffective and M59 just pushes the front in straight lines UNLESS you are carrying a great deal of weight up front and tires bite instead of push.
Even though I have read that manual from cover to cover several times, each time I open it I find some new info that I missed. I prefer missed over forgot.
My M59 sadly doesn’t have a front locker.
My old M5030DT did have Detroit type locking front axle. Worked beautifully on hillside and slop. All four would spin or in a turn the outside front wheel could over sped giving good control. Stayed in 4x4 all the time on the farm. Surprisingly kind on turf even with R1 tires. Could improve with wider and heavier front tires.
