You need to let some air out of those rear tires on that NH, they are upposed to squat some for better traction. We have 2 of the 1720 s with loaders and a Backhoe also. My brother uses one of them to dig out Hayleg and load a TMR mixer . Do you have any implements you could mount on back to give you more traction? I used to hang 6 100 lbs weights to the lower lift arms while using my tractor and loader. I now have a 6' snow blower on it so it is weighted good enough.
