left and right back rear brakes. diff lock, are important to me!
4WD. is nice! but 2WD and above. i can get out of a good amount situations.
though i do rely on the FEL (front end loader) to push or pull my rear out of some sticky guey situations.
when all else fails, i brake the backhoe out, to drag my rear out.
when everything fails. then i end up acting like a monkey, operating FEL, Backhoe, DIFF lock, or split brakes all at once. it may take me a little time, but will get it unstuck.
=================
one thing that bugs me on some tractors. is split brakes are same foot as gas pedal. and there is not enough room to stick both feet wearing boots on. onto gas and brake pedals.
================
2WD, i prefer, more of the time, i end up over using per say the split brake pedals, for tighter turns. and controlling wheel spin.
but there are times, when trying to hit left or right brake pedals to control wheel spin is overkill. and easier to just press DIFF lock. so both rear wheels spin.
4WD, causes a larger turn, that i just do not like. though in muddy conditions if i have 4WD i will use it. so wheels are less likely to spin out.
