I have a new L5240 tractor with no cab. I plan on putting a curtis cab on next year. I have been snowblowing for a couple years with no cab. I would like to plum a 33000 btu heater and set it on the hood right in front of the steering wheel. Is this enough heat to make a difference? it seems to me it's better than nothing and would keep your hands and face warm. are there ports on the engine or do I tap into upper/lower heater hose???
