Re: (ET) How is the snow blower attachment wired?

Snowblower like all other working Elec trak devices never uses the frame as a ground. There are three wires coming off the PTO. The two "wing" ones are + and - 36 volts if I recall, and the center one is designed to allow a device to "short" the motors to positive when the PTO switch is "off". This is used to stop PM motors from spinning quickly (like a blade brake on the deck motors).
The snowblower, being a series wound motor, can't brake so it simply uses the + and - to run its series wound motor and the center wire is not used. Same for the tiller.
So you should be able to wire one of the two slanted blades to +, the other to -, and see how the blower is going. If it's going backwards, reverse and try again. Oh and use a big contactor to turn it on and off.

I would like to power my elec trac snow blower attachment using an 
accessory 36 volt pack. The snow thrower has a large 3 prong plug.  To 
wire a new receptacle for this plug, are all 3 lines to the receptacle 
coming off the positive terminal of my battery pack and I run a ground 
from the negative terminal of the pack to the frame of the snow blower?
Sorry for my lack of knowledge
