Powered Snow Blower Chute Control

[wallfish 16,986]

So the worm gear setup on the blower worked OK with a motor turning it but once in a while a chunk of ice could bind it. Turns out it wasn't totally all the worm gear's fault for questionable performance as I found a dimpled out part of the sheet metal which was affecting the smooth travel of the plastic chute guides. Of coarse that was discovered after making and attaching the new 85 tooth gear so decided to just go forward with the chain drive after fixing that. It still needs a little tweaking but so far so good. Strong and powerful so it should just crush any ice chunks, hopefully. Thinking about attaching a plastic guard to cover the entire chain and motor gear. No modifications to the blower itself except for enlarging the holes on the chute itself so it can always be changed back to the worm gear set up using a motor or handle. The thing about the chain drive is it will be nice to shoot snow 45-60 deg backwards instead of turning the tractor around. BTW, the notches on the chute for the worm gear drive perfectly fit #35 chain so grinding in new teeth all the way around on that plate would have worked too.

Also making new windows for the snow cab using clear 20 mil marine vinyl and aluminum frames. Covering the vinyl of the cab with clear Flexseal out of a can with a brush turned out to be a successful experiment. I covered a big portion of the cab already and it sticks VERY well and turns the vinyl cover into a nice pliable sheet of rubber. Very happy with the results of that so far! Bought a couple spray cans of the red which I may spray on over the clear after some testing.

Added new rubber paddles too as the old were worn down some and a new front gearbox support.
