It's a Bison NB 80-120 with Hydraulic angle and off set 815# Do you think a L4060 can pull a 96" blade?
Typically I think of that size tractor making better use of an 84" unit. But there are some people on various forums that seem to have good luck using a 96" blade with that size machine.
My 2 recommendations would be to get the skid shoes for ANY rear blade that you get. They just make life easier.
Fill the rear tires, it helps out when actually working the tractor.
On a side note, this is a cat 2 hitch on the blade, is it not? Is your cat 1 hitch going to be compatible?
Sorry, still don't see that model. How about an NB80-210?
Pictures please when you get the blade.
