I have two.
One for about 10 months and the other for about 8 months.
The Husqvarna R322T AWD is very good on steep slopes.
I have a known 19 degree slope (I measured it) and it will carry my 275 pounds up this hill in forward or in reverse with no problem.
It has plenty of power and unbelievable traction.
The two R322T mowers replaced two Wheel Horse I once had.
Often my wife and I have both R322Ts mowing at the same time.
