I have a .pdf of a 31-page owner's manual for the 451 from 1972 (Sperry New Holland) . It's 2.6 mb so best send me a pm with your email address. Dick B

how do you adjust the angle of the drive belt pulley on a 451 nh mower? Instead of being at 90 degrees to the frame mine is about 60. the belt isn't straight. any suggestions?:confused2:

The big pulley should be in about the same plane as the smaller one. The belt will tolerate a few degrees of misalignment - but I'd guess that even 10 degrees off would heat up and wear the belt. Sounds like something is bent, broken or missing. The whole assembly is made to pivot when the bar breaks away, but it should all rotate as a unit, with the belt still lined up in the pulleys. Could you maybe post a picture? Take care, Dick B
