I had the same dilemma last year and finally decided on the rear mount blower. Reasoning: The front mount pretty much dictates that your tractor for the time the blower is on it, is ONLY dedicated to snow removal, and it is no slight task to take the front blower off. I've got a mile of dirt driveway to do in Lake Tahoe. So, as long as the snow on the sides of the road is less than 24" high, I use my back blade to do the driveway. It's quick and I literally drive down the road at 15 mph and in less than an hour I am done. This leave the front blade to be used to push piles of snow out of the way when needed. When the snow gets deeper than 24", I take the rear blade off and add the 84" snowblower. I then use the front articulating blade to quickly do the driveway (it doesn't do as nice of a job as the rear blade, but it is still fast) and when I encounter either my driveway or my neighbor's I turn the tractor around and use the blower. Only on pretty rare occasions, do I need to do the main driveway to blow the edges, and that ends up being much slower. Overall- for me- this seems to be the best solution.
