Re: (ET) Snow Thrower Speed (added data)

Just to clear things up. This snowblower is a single stage and is built just like the GE 42 inch unit. It has a jack shaft and pulley where the GE's motor is mounted. I plan on putting wings on it to make it 42 inches wide, and mount it on my E20, then power it from the PTO plug. The motor came from an Cushman Electric Mule (industrial truck) that was scrapped out. I have the speed control resistors that I could use to slow it down if needed.

Ralph,

I checked into this before my conversion. Most augers run around 1000 RPM. The electrac has a no load speed of 3100 RPM. It is important to note the speed will drop quickly with load. I set mine to run 800 RPM no load. I wanted the increased torque for wet snow more than distance. Even with the belt drive to a two stage snowblower connected, you may see 8000 rpm from the motor.

Does anyone know the rpm of the snow thrower auger?

I am converting a 36" craftsman unit to electric. I am using a 36 volt 3 hp. 3000 rpm series wound motor to drive it. The way it is set up now the auger speed will be around 1300 rpm. It is belt driven. It has a spring loaded idler pulley, and I am hooking up a limit switch on it to shut off the PTO relay if the belt brakes. Thank you for the info on series motors not having speed regulation without a load. It came at just the right time.
