Snow Blower Conversion

[ChrisMunn]

Hey Everyone I have been a long time lurker here and have benefited from the knowledge here on numerous occasions.

I ended up buying a JD 2210 with FEL and scraper, but I have been yearning for a blower to go with it. Well today I managed to aquire a 48" blower off a smaller tractor (single stage / belt drive / front mount / mtd brand) for free. I promptly headed of the local scrap yard and aquired a $25 100hp right angle gearbox off a scrapped rotary cutter.

My question is what speed do I need to drive the single stage auger and thrower assembly?

My plan is to use the right angle gearbox to drive the input shaft of the blower. I will attach the rear pto (540rpm) of the tractor to the input of the gearbox.

The Blower seems to gear down the input shaft from 2:1.

This means with a 1:1 right angle gear box I would be running the auger at about 265 rpm. Is this enough or should I change the ratios?

You help would be greatly appreciated!


Thanks

Chris Munn

Just an Idea, Why not mount it on the FEL and run it with hydraulics off the 3 point. This way you can drive forward and not have to keep looking back over your shoulder.

It wouldn't be that hard. Just a platform with a 3 point set up. A tank and a pump driven by the pto, a valve(with a built in relief valve) and two hoses up to a motor that drives the blower. You could even get fancy and use remote 12 volt valves. I don't know your capabilities but its not as hard as you would think if you keep it simple.

Then the pump set up (if built with spare valves) could be used for other things like homemade brooms and homemade rock hammers, etc. The possibilities are endless.

I've been wanting to do this project for sometime with a cadtrac type vehicle. Got all the parts, just no time to do it.

Just my two cents. But its just an idea.

as a rough approximation, at about 2200 psi, for each gallon per minute you get one horsepower.
So, if you have 10 gallons per minute, you have a little more then 10 horsepower to drive the blower. Which is not very much.
One thing the blower guys seem interested in is the tip speed of the center thrower. If you know the diameter, and you can research the optimal tip speed, you can calculate the RPM.
