There seems to be so much interest in the M602 Cab that i'll fill in the story. My Dad had a welder,torch,grinder,and an electric drill and built about everything he could especially when they had no money. We had a couple Heat-Housers over the years but he built 4 cabs starting with a open back cab on a Allis WD in the late 50's. It was pretty crude with paned house windows in front & sides.
He Built a Cab on a Gleaner E combine that looked about like a factory cab and then a U302 MM with a Roomy cab that was as wide as the outside of the fenders.Since it was so big he used Plexiglas for windows and you could not see thru it plus what ever heat came from the engine was gone.
This 602Cab is maybe tall enough for a 6 ft person to stand up(not me at6'4")but I think it is narrow because he installed actual safety glass windows that open. At least a person does not bump your head getting in. Even without floor mats it is somewhat comfortable with engine-gear-body and sun heat without a heater. All of his cabs were made heavy enough to be roll cages plus this one the top above the windows can lift off on the occasion the hydralics need attention or other maintenance.
We sold the tractor in 2000 on a farm auction for about $750.00 including the Duals and the guy that bought it left it parked outside by a building for 10 years without anything on the stak.(Cab protected the gages&interior) It was a good thing because all his restored-nice tractors
inside burned up with a heat lamp fire. I bought it back(about the same amount) and had planned on discarding the cab or trying to modify it to look like a factory cab since it is kind of eye sore.
I been moving implements & buildings over the road this fall& winter and could not be prouder of the Ole Man and his odd looking cab.It needs some TLC and I would like to make it look more "factory" but it does have some character that you are not going to see anywhere else. I appreciate you folk saying "interesting" instead of what you could say as "it is what it is"
