Hi all... new to owning a tractor, but not new to handling equipment. I recently bought a 2018 m7060 tractor with the push button 4x4. Long story short, all indicators show I'm in 4wd but front wheels don't turn at all and about got me stuck. I checked the couplers on the front driveshaft (propeller) and they seem to be fine. Dealership said possible solenoid, but I can't find anything at all online about it or even a part number if I wanted to buy it. No schematics or anything. Can someone point me in the right direction? Would be much appreciated.
