WD-45 and PTO speed

Dfude1 · Sep 13, 2010

Due to tons of snow last winter, I am looking at getting a snowblower for my WD-45 (PTO/3 pt. hitch)as the front end loader was not much help with 10 ft. of snow piled everywhere. But, I can't figure out what the tractor is capable of taking? The shop manual says PTO speed: "RPM at 1400 of idle 548" and "RPM at high idle 1677 to 1722-656 to 674". What the heck does this mean? I have found a 1 stage blower that is rated at 1000 RPMs and seen some more rated by hp. What is crucial to know before I buy one?

The PTO on a WD45 is what is called a 540 RPM PTO. Equipment is rated at one of 2 speeds the 540 or the 1000 and the WD45 does not have a 1000rpm PTO. Also that 540 number is sort of a magic number since it is only a ball park type of thing

You need a snow blower with a rated speed of 540. What the book is telling you is that the WD45, like many older tractors, develops the standard PTO speed of 540 at a relatively slow 1400 engine RPM's(approximately)

Yep, I have a pair of notches filed into the throttle quadrant for "PTO Speed"..!

Just about 1/2 throttle, I would say..

Man, I love it when the governors fly open on that Brute..!!
