I installed the UPI Inferno Cab Heater into my 2016 Gravely Atlas JSV a few weeks ago. Instructions were clear, and easy to follow. The hardest part of the entire installation process we getting the air out of the cooling system, it took me a few hours to get everything bled correctly and for the heat to start coming out. Once you have that covered, this thing will roast your face off. The cab gets nice an toasty, which is great when you live in a sh*tty winter state like Massachusetts.
