It occurs to me that it wouldn't take too much effort to convert a front mounted snow blower into a front mounted blade , using a simple flip down blade attached to the snow blower. You might have to reinforce the snow blower frame, but you could have both snow removal devices on the front of one tractor.
On another subject, in 2009 we had two heavy snowfalls within a week. There was about 20 inches of snow on my 400 foot long dirt and gravel driveway, more than my equipment could handle. I hired a guy with a 4 wheel drive Kubota tractor , with a bucket on the FEL. It wasn't an especially large tractor; about 30 to 35 hp. I'd guess. I was amazed how easily he blasted down my driveway ,using the bucket as a plow, and finishing the job in about 15 or 20 minutes. I think that 4 wheel drive made the difference. Sadly, the next year I had the same amount of snow to remove, and the guy with the Kubota subcontracted the job to two drunk guys with a Bobcat with a front mounted bucket. Yes, they cleared the snow in about an hour , but tore up my driveway and surrounding lawn badly in the process. I'm still repairing the damage 3 years later.
