Don't have the mower ,so I don't know how it cuts .I do plow snow with it and it has plenty of power . when you hit a snow bank and stop, it will spin the tires on concrete with chains, in high gear , with wheel weights installed , and a 225 lb. driver .It won't stall. The wheel horse plow has a blade angle lever that you can reach from the drivers seat . very useful plowing machine.
Ive got one it has the 8 hp kohler and the 8 speed tranny its just as good as its big brother but not the big engine the one you are talking about if it has the all red hood it was sold by lowes and they were theonly ones to sell wheel horse out of all the big box stores
As far as cutting I dont cut with mine nor do I cut with any of the other wheel horses I own last count over one hundred
If we are talking Wheel Horse 300 series then yes, they cut great. I have a 416-8 which really between the 300 and 400 there isn't much difference but engine choice and deck, but my 42" 3 blade deck cuts unbelieveably well. I replaced a new Cub for an old Wheel Horse both with 42" decks and mine WH out cuts it. The difference I feel is the tall dome deck and the fact that it floats.
