Not to fret. I have plenty of spots on the property that are tillable and I have a great garden - that myself & all the wild critters enjoy. My main crop here is Ponderosa pine.
I looked at a cabbed version of my Kubota when I bought a new tractor and decided I would stay with open station. I still enjoy being out in the weather and don't do any work with a rear cutter - don't have any ground dwelling bees or hornets and have a full set of Eddie Bauer down winter clothing. At the time, a cab for my Kubota was an additional $6K to $7K. Another advantage here - whether its very hot or very cold, the humidity is always very low. The only time the humidity will be above 30 to 35% is when it rains.
