I have had several ATVs over the years for our small farm; Polaris 500, Yamaha 750 Griz and 550 Griz.
Presently have a 09 Yamaha Grizzly 550. Plenty of power for snow plowing and hauling. Also has power assist steering and is very easy to turn the handle bars, especially helpful for the wife.
I downgraded from the 750cc to the 550cc as I wanted the power assist and, for my purposes, do not miss the extra power of the 750.
We use the ATV every single day of the year. Some of the chores it handles: haul hay bales to the horses, pull muck wagon, pull manure spreader, pull heavy harrow to level gravel and dirt, pull log wagon, ride to the mail box, plow snow.
I don't think you could go wrong with any of 'em, Yamaha, Honda, Suzuki, Polaris, Kawasaki etc. Good luck with your choice.
Yamaha does not make a 750, wish they did, but for now 700 is as big as you can get.
I have a 2009 Grizzly 700 with power steering, and absolutely love it. It has plenty of power, and the EPS is great for those long days on the trail.
