Depends entirely on what hump you are straddling........:laughing:
If, in fact, the floor or seat based is humped is about engineering for drive train components. Thats it.
It's there for a reason...... component clearance.....:confused2:
All the large frame tractors are flat floor/flat seat pan with industry standard seat mount bosses (I know, I just changed to an air ride seat base on my M and 105.....)
