So you're just speculating then. No actual factual information on sources of cabs.
And yes, the 2650 has AC and heat. But we weren't talking about cabs with AC on subcompact tractors. Were we? That was something you brought up, not the OP.
OP asked about factory installed cabs with heat.
Come to me with facts, not opinions. Or say, "I think... ", which is fine.
And if the FACTORY puts the cab on the tractor, isn't it a FACTORY CAB tractor? How do you KNOW each one of those cabs weren't specifically made for the specific model it is factory installed on? I mean KNOW, not speculate?
Really don't see where you're going with all this?
Not going anywhere. pointed out simple facts. Go look at Mahindra, TYM, etc at their cabs sometime and then look at others that are factory that will tell you right there. Kioti is a field cab not put on by the Factory, TYM doesnt put cabs on anything until you get to the 39 hp version, same with Mahindra. Maybe they are provided by the factory, but those red boxed cabs are clearly an after thought on those tractors in the sub compact class, which again doesnt make them bad or not as good.
Take it for what it's worth, if you want a sub compact/compact tractor under the 20 hp that has both heat and AC, installed and designed by the factory with a curved back the kubota 2650 is the only tractor to do so right now. Simple fact there. take it for what it is worth. Yes there are field cab options for a few models and brands, but they are the boxy run of the mill cabs found on anything, JD has the same things except there are curtiss and come in green or yellow.
