This afternoon I fired up the diesel heater and the B2601 and went out and blew snow at the shop it was -7*F and the wind was blowing 15 to 20 mph I was out for .6 hrs and it was comfortable in the cab, heater was set on H6 had my vest and Wrangler storm Rider jacket and a set of insulated gloves. The other day I installed an extension on the hydro reverse pedal, well I don't like that so when I got back in the shop I removed it. I think I'll get use to it as original, also installed a outside temp gauge but its to dark in the cab to read it will have to figure something out for that. I did add a shot of Polar Power to the fuel to prevent gelling I don't think I really need it as I have artic blend fuel in the tank but it can't hurt anything
