    Default gear box

    I need to make a reverse drive gear box for my snow blower, in a quandary as to type should I use 2 gears, or 3 sprockets and chain. Had a quote for 2 gears and almost died $2,800.00, the gears I had quoted were 10 pitch 20 and 40 tooth 1" thick 3/4" bore, any body know where I can get cheaper gears.

    Almost to your specification:
    You would have to bush the 40 tooth gear.

    http://www.mcmaster.com/#6867k82/=8oomtc

    20T, 1" face, 3/4" bore. Stock #6867K75 $46.23
    40T, 1" face, 7/8" bore. Stock #6867K82 $91.63

    These are for finished bores (keyway and set screw). Prices are about a third cheaper if you get plain bores.

    You are going to make a snow sucker?

    I know, blow is only an expression.

    With the number of snowblowers on Craigslist, why not just buy one?

    Well I have the blower already and you don't find many 48" 2 stage that mount on the front of my Kubota, well it didn't fit when I got it but it does now, ran it hydraulically last year but too much slippage and heat build up even when its 10F outside. Have a center PTO that can run up to 2,000RPM thats why I need a gear box and the PTO turns the wrong direction.
