95101 Spreader Single Knob Blizzard Western Fisher Inbed Salter Variable Speed 1.25 Cu. Yd. ( 29246, 29247 )

This can be replaced with the new 78102 controller for the later spreaders. It would only use one one knob on that controller. 

Here is a New Single Knob Control for the 1.25 Poly Blizzard, Western Tornado, and Fisher Poly caster in-bed salter. The control is 95101. This will work with the 1.25 cubic yard spreader only - these have a rubber belt not a chain.

There is a knob to control the speed of the spinner and belt, a power button which also turns on the blast function.

Comes just as you see - control and includes the bracket. The wiring plugs right into the back with a 4 pin connector.

Fisher and western use an identical control other than label which is # 29246 Fisher and 29247 Western. 

If you need the control vehicle harness for it, that is part # 29221.
