What does this belt pulley fit?

[Peter C]

Hi, does anyone have an idea of what this fits on? It's 14 inch diameter with a 4 1/8 inch center hole and mount holes spaced 3 3/4 inches around the center.
Letters say Rockwood and This side out.

Thanks
Pete

Hmmmmm...not sure.....need to see the bolt pattern on my H........

side mounted PTO pulley maybe an H model?

[Gary Dotson]

I know that different sizes were available but I don’t think I’ve seen an H with one that large. F-12 had a pretty large one.

[Jim Becker]

I could be wrong, but I recall the H/M pulleys having a large offset. If you tried to put this one on, it might run into the transmission housing.

[Peter C]

Thank you for the replies. As far as the offsets goes the hub is centered and 3 1/4 inches in from each side.

Bear in mind, during the early days of mechanization, most industrial machinery was driven from a central power source through a system of jack shafts, pulleys and belts. This pulley may not necessarily be from a tractor.

[Peter C]

Yes, I hadn't thought of that. I just saw the red paint and thought of tractors. I'm only familiar with Cub tractors.
Thanks
