I used my NH 50 to unload a full pallet, but the loader has a higher lift rating than the TYM. (NH T60TLA 2371 @ the pin; 1849 @ 500mm) Even so, the pallet of pellets was all it could lift
Before I bought this tractor, I studied Tractor Data on various models in the 35 to 50 hp range, particularly loader capacity. All of the tractors listed capacity at the pin, many also listed capacity at 500mm from the pin. As a rough average the loader capacity at 500mm (just a little shy of the pallet center) is reduced +/-25% of the at pin rating. My personal recommendation would be to remove 2 to 4 layers before unloading the pallet.
