pto rpm on ford 8n

Wanting to get a snow blower was wondering if
if anyone could tell me the rpms that the pto runs at.I have an 8n with the sherman 2 speed trans.

Assuming you have the more common Sherman Step-Up transmission (vs the less common Step-Down) then PTO speeds are 545 RPM at 1500 engine RPM in straight through, and 817 RPM at 1500 RPM in step-up mode.

If you'll listen to the voice of experience, I'll gently suggest that you not do this. My Dad had a similar tractor back in the late 1960s. He bought a single-stage Vee-type snowblower to run on a 2N tractor with a Sherman step-up.

The lack of live PTO makes this pretty impractical. The 8N doesn't have enough power to really throw the snow unless you creep along slowly at nearly full throttle. But you can't. The transmission/axle ratios are such that your minimum travel speed is 3MPH or more.

The lack of a live PTO means the speed of the PTO shaft is tied to the speed of the rear wheels. In Step-UP mode the PTO spins faster, but so do the wheels, so the blower is fed too quickly and clogs.

And then there are issues about getting covered from head to foot with a fine dusting of snow, or getting a crick in your neck from backing up. After a month of pretty unsatisfactory results, we sold the blower and bought a blade for the 4WD pickup truck. You can plow in shirtsleeves with the heater and radio going, and the rig moves the snow a lot better than the 9N ever did.

A stronger tractor with a live PTO, something like an MF135, or Ford 4000 might push a snow blower OK. But the 8N won't cut it. And I do like the N-series, having learned to drive on my Dad's tractor 40 years ago, and I also own one today.

540 rpm, same as any other tractor with a 6 spline shaft

Some of those funnel blowers are reversable so you can pull them. (the funnel is open to the tractor and you drive forward) First is slower than reverse so it works better, not ideal, but better than the backup tecnique.
