White snowcasters from the factory were only available in 1984. That means all of them were designed to work on 3 digit tractors with the engine facing the correct way in the frame. You have a 4 digit tractor with the engine turned around to face the wrong way. :smile:dblrz143 said:Can't wait for snow. Just installed a White Snow Caster on the 4016. But do not be alarmed....I have the blade on the 446 also. Never used a snow caster, so this will be a new experience for me.
