A six foot snowblower isn't as wide as the rear end of my tractor. And after watching videos of tractors running the type of equipment I planned to use, I went with the 60 hp. I started out thinking I'd compliment my excavator with a skid loader, then arched through looking at telehandlers to tractors. With help from the folks on the Massey forum, my suspicions that a HST transmission was the way to go limited me to around 60 hp tractors. I could have purchased a Deere 5083e pimped out for about even money, or a JCB 506 for about 30K more. The problem with the small telehandlers is that they do not have high-flow hydros and since everything they do is on the front end, hi-flow was necessary. In the end, I decided a tractor offered greater flexibility and I was limited to 60 hp. I never even considered smaller tractors since they don't have the deck-over lift capability I need.
For example: Here we see a Kubota L6060 running an Agrimetal 84" wide Max Snow. The Max Snow is arguably the best two stage blower on the market, yet we see the L6060 struggle. I can only imagine how long it would take an even lower hp tractor to blow out this drift. Oh sure, a lower hp tractor can run this very Max Snow, but if you have other things to do, other places to go, time is money.
FWIW, I'm entertaining purchasing an Agrimetal MTC 3480 Max Twin.
Sorry Eric but that is a poor choice for comparison. He is running the wrong tool for the job He should have a much taller twin auger blower and his approach would need to be slower and steady. My DK40 would run that blower just as good as he is doing with his machine with no problem I run an 84" blower on my DK40 and have the pleasure of getting big ugly drifts even from the smallest snow fall so I am not just guessing here. Deep drifts you want a taller dual auger blower and lots of patients. I also must point out that I think you will be highly disappointed with the dual fan no auger blower on your tractor. I wouldn't run one of those with anything less than 100HP in a size able to tackle any serious drifts like this one pictured.
