Being turned around for extended periods wears on me and I don't even snowblow (I clear with a rear blade since we rarely get more than 10" at a time here). When I do grading or landscaping and run the box blade for hours at a time, my neck and shoulders get sore due to the amount of time I spend turned around. It does help a bit to sit cocked 45-deg in the seat so you can rotate front to back more quickly with less neck swiveling, but still I feel it in my neck.
I put in front and rear cameras -- main interest was front for precise loader work, but the rear comes in handy to let me glance at the implement without having to turn around, and it's great for backing up. However, I wouldn't want to exclusively get my rear view through the camera all the time, such as for snow blowing. It's great for monitoring the rear implement when going forward though.
As for the
L4701, it most definitely is more tractor in every way. But from what you described, nothing suggested you needed that larger frame size. If you do plan to do any skidding or logging in the woods, it will be important to get the smallest tractor that will still do what you need, as maneuverability in the woods can be a key factor. It was for me, which is why I purposely went with a smaller tractor (
B2920) when logging our property and then later moved to a larger tractor (
L3200) since I was doing more work out in the open and needed more capability. I am now looking at maybe getting an
L4060 at some point for even larger tasks out in the open, but that will be even more cumbersome in the woods. I can say with certainty that for my initial logging/skidding work, that
B2920 was a better tool than the bigger options, by a long shot. It was like a mountain goat in the woods, whereas the bigger tractors are more like elephants.
noose covered the important benefits of the 4701 well, but one of them -- four-cylinder versus three-cylinder -- is actually not a benefit, or at best a wash. Three-cylinder engines are significantly smoother than fours, and that is an inherent trait. There have been some threads about this here where some people discover this by accident, but it comes down to the inherent balance in an inline-three that you cannot get with an inline-four. So with tractors, I do not see four-cylinder as an advantage over three-cylinder. All else equal, you will be more comfortable and the engine will be more refined with three-cylinders. There comes a crossover where you have to go to four-cylinders for more power, and at that point you have no choice.
There is quite a bit more value in the Grand L models, regardless of whether you get the cab. The more advanced HST is a big one. Weight is another. And overall comfort/refinement is a third. Yes, it's a big price jump, but I feel like you do get what you pay for in the Grand L models. It comes down to how important those extras are to you and your uses as to whether it's of value to *you*.
