Finally found a 451 blower!
 

Hey Guys I have finally located a Model 451 Snow Blower close by, but before I contact the seller and go make a deal I would like to know if there are any particular areas that I should be concerned with. What are the weak points on this model if any? I will be installing on my 1872.

Any guidance would be greatly appreciated.:bigthink:

Congrats! Hope to see some pics of it on the 1872 this Winter. :beerchug:

you need a 450 not a 451 the 451 is made for a 6in pto pulley the 450 is made for the 4 1/4 pulley like your 1872

Ray,
Are the gear boxes different? Or just the pulley?

the pulleys are the same its the gear boxes that are not the same

I understand that the 451 will work it will just turn slightly slower therefor not blow quite as far as if it had the larger pulley. Do you thing I can get away with it? Maybe change the pulley on the blower to match the one on the tractor?? In my area I am lucky to find the 451 let alone a 450...been on the search for more than a year now.

ok to make it work you need to put a 6in pulley on the pto clutch which I may have here just the pulley not the whole clutch

My clutch has 2 pulleys...the outer is 6"x1/2" and the inner is 4 1/2"x5/8" is it possible that is the pulley I need?

I ran a 451 blower on a 1450. I did make sure that I was actually running 3600rpm, and it did a good job for me. The guy I sold the package to said it does a good job for him too. BUT, now that I have a 1572 with the correct 450 blower, it does an amazing job. It impresses me every time I use it. Get the pulley from Ray, and be prepared to be amazed with how far you will send that snow. I am not sure about the double PTO pulley. I have never heard of that. If you use a mower deck on this tractor, you can likely switch it's double pulley for one that will work with the 6" PTO. Where in Ontario are you? I am near Brockville.

now it sounds like you have a 2 fold problem you need a pto as well never heard of a 2 groove pulley for a 1872 never saw one either
