Q: I just received the Voltmaster PTO 15/12 generator purchased from you guys. I held off on buying the tumbling shaft until I figured out the platform that I am bolting the generator to. Is the only difference between 3421 and the other tumbling bar offered the length?
by Bryan Busch from Connecticut on February 09, 2012

A: Yes, the only difference is the length of the shaft.

Short Shaft - 37" - 50"

Standard Shaft - 57" - 67"

by Jared, Product Expert
Q: Does this drive shaft have the rubber inserts (spider) required by the generator manufacturer?
by Jim from Tennessee on February 05, 2011

A: The Voltmaster Shafts do not come with rubber inserts. There is a safety cone or shield that will cover the junction between the transmission and the shaft.

It All Works Well
I purchased the Voltmaster 12KW PTO generator and also the tumbling bar and trailer. Everything fit together perfectly and simply. It all works well.

The service and value of products from Electric Generators Direct is unbeatable. I researched extensively before my purchase and this was the best deal.

I will buy more as needed.

A Great Accessory For Our John Deere
We live in the country and depend on our own well. This model gives us enough power to run the pump and many other conveniences.

The wattage was right for us, the price was great (no need to pay for an engine), a great 3 year warranty, and it was made in the USA!

The available accessories made setup easy. We added furniture dollies to make the setup easy to move around when not attached to the tractor.

The quality of the three parts is top notch.
