In a perfect scenario, the rear wheels of any tractor 2wd/4wd should be doing the majority of the pushing. The rear axle is designed heavier than the front axle. That is why it is called front axle assist. The force of the rear axle is transmitted through the axle housing, transmission, bell housing, engine block, loader sub-frame, loader, bucket, and finally the cutting edge. Any part not in line with the direction of force will be subject to flexing or bending forces. Thin castings at 90 deg. to the line of force are likely to fail. Next imagine the forces generated by carrying a bucket load of dirt across a field. CNH should have a recall, where they add sub frames to all the tractors with loaders that have been sold. Spend the engineering dollars on something useful, as opposed to graphics and deluxe cup holders.
Handy said he would like to have a loader on the tractor. Most people max out the lift capacity of the loader with dirt, and then travel as fast as they can without being thrown out of the seat.
