Legroom, legroom, legroom.
The CUT I use the most (smallest, FEL bucket, grading, moving trailers) has the least of it & at 6' 2" 175 lb I bet I'm not the tallest guy here, the widest, or have the biggest feet. (11 B)
btw, Just like when testing a gun's fit close your eyes and reach around for the foot controls, gearshift, range selector, joystick, etc. (I've practiced dismounting 'blind' too, .. or which side is easier to get on/off?) IMO if one could find them all in the dark that'd give them some insight into how well the machine fits & feels say when spending long hours in the seat, fatigued, barely awake, drunker 'n ol' "Cooter" Brown, etc.
