What you are asking is hard to answer without knowing what all you will be doing with these machines when not plowing and what conditions are ware you will be plowing.
I have both a 975 (1200lb machine) Bobcat and a IT28 Cat tool carrier (loader).
Bobcat, + works best in tight areas, between cars, around buildings. cheapest to maintain, better fuel usage.
- Slow travel speed, rougher ride, no tunes, louder, greater tire ware, less comfortable,
IT28 + Push more snow, Faster in a large lot, Faster road speed, Better heater, Sirius radio, air ride seat, better viability,
- more expensive, higher maintenance cost, uses 2x the fuel in a day,
I started with the bobcats (2 of them) back in 1982 and they still run great but I am getting older and like the creacher comforts offered by the loaders. now a new Bobcat if they still made one that big would be much friendlier to operate would be worth a try. I still use the bobcats when working a parking lot full of cars or in tight areas. I have both a 9' and 10' wide bucket for snow removal. Also I run studded 10.00 x 20 snow tires on bud rims which makes a big difference for traction. The bobcat will load a 10yd truck with snow faster then the IT28 due to a faster loading cycle. As for the IT I use a 12' angle blade for plowing and light stacking up to 12 feet high. But have to change to a bucket when loading trucks.
If I were younger and doing small lots and not traveling far then I would stick with the bobcat. but as I am older now and like to relax a bit when working and my route is spread out over 10 miles the loader is the only way to go.
Good luck on your decision.
