I built this snowblower out of an older MTD/Sears that I bought from a friend a few years ago. It was originally only 40" wide, now it is 46" to clear the rear tires. I had to build the chassis myself, I reused as much of the original drive parts that I could, so I would be able to find parts in the future.
As you can see the whole unit stays assembled and drops out together. I can drop the mower and hang the blower in about a half an hour. It takes about another hour to add the lights and trade the handles out and hook up the wiring. I wanted to make it look as if the factory built it so I painted it up Dixon Blue and black. A coworker came up with the name 'POLARBEAR 46' as Dixon names their commercial mowers after bears (ie: Grizzly and Kodiak).
The snowblower uses the same mounting locations as the mower deck. The mower lifting pedal didn't offer enough leverage, and the latch worked backwards for the snow blower, so I reworked that as well. Unbolt he stock pedal and refasten the longer pedal with a normally unlatched lock and now the blower floats without latching, but you can lock it in place by pushing down with your heel, even with snowmobile boots on.
I added electric motors to turn the chute and adjust the spout (a modified window lift arm from a Ford Taurus). The buttons to control these are mounted on the handles, I used some old snowmobile handlebars for these so they are heated as well. I made the wiring harness from low-temp extension cord wire and it all goes back to the battery to a single plug. The headlights are just little driving light assemblies that I mounted on some brackets that bolt to the front of the tractor. The wiring for these go back and plug into the harness that I installed for the headlight for mowing grass. I also added a tail light for blowing snow, but it stays on all year round.
The rear tires are ATV tires mounted on a pair of trailer rims that I drilled holes into and welded pipe fittings into so I could fill them with fluid. There is also three weights bolted to the bottom of the tractor that stay on all year. There is also a small weight box built into the end of the snowblower chassis that acts as a counter-weight to lift the blower easier. I even added wheel weights last year to help with the traction. I didn't want to use chains because I would have to move the tires out more for them to fit
All in all it works fairly well, but the chute need to be larger diameter and taller. The tractor has a single-cylinder Kohler Command 20 and seems to have enough power to run it.
So what do you guys think?

Darn fine looking outfit you made there. Look forward to seeing a video of it tossing the snow. If you wouldn't mine, can you show some close ups of your door opener mods.

Thanks guys. I can't imagine the amount of time I have in it. I think it took me three months of lunch times, and time before work to build it. I work in a body shop so I had all the tools on hand to do the work.
I'll see if I can get a video of it this winter. I'll probably need some help posting it though, I've never done that.

Wow, that is awesome! Very nice work, it looks factory built.

Framedoctor, that is an outstanding feat of engineering! It really looks like a factory design. I like the way you used the power window motors--very clever!!

That is without a doupt the coolest snowblower I've ever seen! You didn't just "make it work". It certainly looks factory. but all the little details you made, like the counterweight box, are amazing. Awesome!

Thanks guys. My plans this fall are to install a taller/larger diameter chute this year. I'll probably change the chute turn motor drive to a cable like the Deeres have. They spool cable on and off pulleys on either side of the chute. The cable wraps around the chute base so one cable pulls as the other unwinds. I think it will be faster/stronger, and the motor will be one the side of the chute instead of the back.

Great job framedoctor! I've always been skeptical about moving snow with a zeroturn because of there lack of traction, but with your agressive tires and wheel wieghts it should do fine. Now just hope it snows!:)

It could still use more traction, but I don't want to add any more weight to the rear axles. I am considering using better bearings in the front spindles.

Have you used the snowblower yet, or did you just make it? Let us know how good it works.
I used it last year but had some belt issues until the last snowfall. It works really well up to 4"-5" of snow. At that point the chute isn't large enough to evacuate the snow and it starts to clog, especially if the snow is heavier. I was hoping it would throw a little farther that it does, I'd say it goes about 20' for the lighter stuff. I hope the larger chute gains a few feet or at least lets me blow the heavier stuff. Otherwise I may have to sort out different pulleys to increase the impeller speed to keep the chute from clogging.

A wider belt from the engine to the drive pulley fixed all my speed issues. I clocked the impeller at about 1600rpm at WOT. This light snow went about 30'. The last snow was a little heavier and went about 40'

It's sure doing a great job! With the maneuverability of a ZTR I'm sure that makes quick work of snowremoval. Your pictures are quite small so I wasn't able to decifer the details-do you have tire chains on the rear tires?
