changing pully sizes ?
Original Message   Jan 14, 2005 6:57 pm
hi everyone,

got a question concerning pully sizing..........over on the IH CC forum theres a person that changed a tractor mounted single stage thrower pully from 3.5 inches to 2.5 inches and shows pics of the enormous difference in distances..............is this an  accepted method of improving snowthrowers in your opinion?................i was thinking ,after seeing this ,about trying this idea out on my JD tractor mounted thrower but would be concerned about damage that could happen................

any ideas or opinions ?

thanks,

bill

Don't ever change pulleys the machine is built like that the ratio would affect power of engine and causing damage too think of it

Been changing pulley raitos all the time  with the single stage your auger has a reduction for the auger drum through the sprockets  formula is the same dia. or  # teeth on a sprocket  20 T  on driver  60T  on driven  raito  3:1 .But remember  increase in speed decrease in torque.

sorry i couldn't get back before now..........................

i would be reducing the pully on the blower itself.......................

more speed would be good for powdery snow (if we ever get any )...........

no torque for the wet stuff is what i dont like...................

maybe i'll just keep it stock , it might work well enough like that.....................

thanks for the replies , they helped alot ,
