I am having trouble coming up with a good safe heat source for the cab on my Agco Allis farm tractor.Whats the problem you ask, just run some hose an add a heater.Well if it was that easy thats what I would do,but this tractor is a Deutz style air cooled motor made by Sami.It has an extra alternator on it to drive an electric heater that comes factory with the cab,but it is very lame so I want to supplement it, any ideas.We have all had the laugh around the shop holding up the propane powered sunburst and saying"what about this",but the alternative needs to be safe and also controlable because the cab has little room for really hot heat sources.I ordered a 11,000btu electric heater from northern hydralic today but I am afraid it is not going to cut it,so I am looking for other ideas.
