Builder,
I really prefer the boom mounted blades. They are much longer, so you do have to keep that in mind, but you can lift the blade much higher if you are in a tight spot, so in the end, not much different than frame mount. The visability is much better also. The front end movement can be a problem with the increased leverage, but that is easily controlled because you can use your joystick to fine tune both your angle (with hydraulic angling kit) and your pitch of the blade. I have never used mine when I could not correct easily while moving if the front started a little sideways movement and this is plowing at 6-8 mph in some reasonably heavy snow. 1600' is really not all that much for such a combination to plow. If one were plowing roads, I would say a truck mount is better, but I regularly have plowed my drive, several hundred feet, and service entrance, another half mile or so, easily with a tractor mounted boom blade. If the one you are considering is anything like my JD one, you could mount your blade, plow and be done almost as quickly as just mounting a frame mount, assuming you have to remove a FEL to mount the blade. To me, in many cases tractors plow BETTER than trucks because even though they are slower in speed, they have low gearing and are very heavy and the downpressure one can apply on a blade does a much better job. I can easily tell after I am done where I plowed and where our neighborhood plowguy plows, and I can go places he would never dare to go.
