This is the set up I use to blow/throw snow:
There is no extra weight in or on the tires. Tractor has 10.50 turf tires and 2 link chains. Tractor has a manual trans (only 500 to 600 units made). Snow thrower is 44 inches wide. Tractor was new in 1996.
My blade tractor:
Rear tires are 23-8.50-12 ags that are loaded with fluid. Wheel weights are from a green tractor. Paid $35 for the set.
Once in awhile I have a traction problem.....usually on ice.
