I have operated both cabbed and open station tractors. I much prefer an open station tractor for a general chore tractor.
- Visibility is much better on an open station tractor, particularly visibility of things right next to the tractor. This makes an open station much better if you are working close next to tall things like mowing along a fenceline, trees, buildings, utility poles, etc. It also makes it easier to back up to implements to hook up.
- You don't have to continually go dust off the windows on an open station tractor to be able to see when operating in a dusty situation. Likewise, you will never have fogged up windows in cool weather with an open station tractor.
- You don't have to go clean out the cab intake air filters every day or two if you are operating in a dusty situation.
- The cab will strike low-hanging objects and makes it difficult or impossible to work close to trees, enter into buildings such as barns with relatively low clearance, and similar situations. You can fold down a ROPS to make the tractor much shorter, but you can't do that to a cab.
- Much easier to get on and off of an open station tractor. This makes hooking up implements much easier as well.
- You can hear your implements working and can tell much more quickly that something is not quite right and correct the condition before you mess up the equipment, compared to if you run a cabbed tractor. Slip clutch equipped rotary cutters are a notable example here, better to raise the cutter or slow down when the clutch just starts to slip in a patch or thick stuff rather than keep going on until you see smoke billowing from the clutch.
- The inside of a cabbed tractor is generally dirtier than that of an open station tractor as the stuff you track in there stays in there. You also have to clean it with a vacuum like you would a car, you can't hose it off or use a leaf blower like you can an open station tractor.
- It is a whole lot easier to work on the rear half of an open station tractor than a cabbed tractor as components are much easier to access.
- Air conditioners seem to be a fairly common item to fail/require expensive repairs on cabbed tractors. A cabbed machine with a broken A/C is miserable, even with the doors open.
- Getting a tractor with a cab where that model is available in either open station or cabbed often mandates other options as well, which you may or may not want or need.
- You are actually outdoors when you are running an open station tractor while you are inside when you are running a cabbed tractor. Much of the appeal of having property is being outdoors, so why would I want to go inside of a cabbed tractor?
