Just bought a used 42 inch JD snowblower attachment. The gears were demolished and JD wanted 695.00 to replace gearbow as a unit. Took the gearbox apart and noted the measurements. Lo and behold it turns out that the gearbox is the same as what is in a Cub Cadet snowblower attachment. Bought both gears for 125.00
at cub- cadet dealership.
The part number for the blower is 190-303 checked website WWW.partstree.com
