Well, I do not have a ton of yrs on a tractor - however, I actually have just purchased my first tractor - I too was cab vs open station, oh I was POSITIVE I would buy nothing but a cab model, after all, I would be putting a fair amount of hours in winter weather clearing snow with a snowblower (Frt mount) - been doing it for the past 10 winters on an opencab lawn-mower tractor so I knew I wanted to get rid of the blowing snow in the face situation. Well when it came down to the purchase time, low and behold I found a great deal on a used 24PTO /30ENG HP New Holland (a brand I hadn't even been looking at as the nearest dealer is in the next province (I live in New Brunswick Canada (have all the seasons too, along with tons of bugs)). So anyway, the NH came with a cab, not a factory one, but rather an aftermarket (sort of a canvass) framing and covering. My first summer of running it, I had removed the doors for the air-flow and put them back on for the winter. Thru the winter, I had been watching a vid on YouTube and the fella suggested that an open cab for a first time owner is extremely advantageous as it will allow you (and I) full view around the tractor - most specifically where the tires contact!!! He suggested that it greatly enhances our learning of the capabilities, the limits and just where it is on the ground in relation to obstacles.
I know pretty long winded - but anyway, this summer (well spring so far), I removed the cab material and left the canopy on. Within the first hour of operating the tractor in this configuration, I was sold on opencab!!! In all honesty, the open cab is a pleasure to open from, however, is it ever nice to know I have the cab to be reinstalled for the winter. So the video recommendation was certainly right (IMO) and I do not foresee "wishing" I had a cab to avoid the bugs (Watkins Bug Cream and good for 6 hours!! LOL).
If you buy a cab model, it is a lot of work to remove it (if there was a desire to) and just the opposite if you buy an opencab and get an aftermarket structure and material to cab it in for the winter - a canopy is a must as it lessens the sun beaming on ya for the hours of mowing and/or working the tractor in the rain!!
I sure hope this input/feedback helps - cheers
