I think the final gear ratio is a little higher in the eMax than the Max. Spec wise they are pretty close, but the Max is built like a conventional 50HP farm tractor, just smaller. The eMax is built like a BX sub-compact with a ladder frame and rubber mounted engine. I think that makes the eMax lighter which is perhaps good for mowing and other chores. Neither design method is good or bad in itself and most manufacturers have tractors built both ways.
I prefer the Mitsu built Max with the conventional big tractor design, but obviously a ladder frame sub-cut works well since Kubota sells boatloads of BX's every year and folks are quite pleased with them.
MahindraDon, glad to see you back.
