The cab vs no cab debate totally depends on your intended uses. A cab obviously offers comfort, and some protection as well. There are downsides to a cab, though. Decreased visibility (sometimes), tighter quarters entering and exiting the tractor, and the cab is only good when the climate control works… a cab with functional AC is great… however there’s nothing worse than a cab with poor AC, or AC that quits workin altogether. The other thing people don’t usually think of is the fact that a cab invites rodents to the interior of your tractor. No matter what you do, mice will inevitably get inside the cab at some point. If they make themselves at home in your headliner or ventilation system, that awesome cab will instead become a urine stench box of hell.
For me personally, for typical jobs around the farm/homestead, an open-station ROPS tractor is the way to go. If you’re going to spend long hours mowing in summer heat or pushing snow in the winter, then maybe a cab would be worth the extra coin and hassle. But that’s your call.
