Can someone tell me what the efficiency of a mechanical transmission is compared with an hydrostatic transmission? Specifically in a wheel loader application where the mechanical transmission has a lock-up torque converter and a full powershift planetary gearbox versus an all hydrostatic drive that replaces torque converter, gearbox and drop box.
If you have a good technical reference source to quote that would be excellent too.
