Bought a $100.00 golf cart cloth / plastic cab cover from Northern Hyadraulic Tools - worked fine at keeping the wind and snow off. Had to wear the usual heavy clothing for warmth. But no biting wind of blowing snow to deal with.
.
Since replaced the cover with home made lexan side panels and door for about $250.00 and installed a heater core from the junk yard to bypass some returning engine coolant through the cab. Hooked the heater blower motor up to blow on the inside of the windscreen, Have to run the engine a little faster to get the necessary lift from the water pump.
.
But that cloth golf club enclosure was a swell quick first fix.
