Does anyone have any firsthand experience with Gravely or Ariens rear engine riders? I am looking to replace my Husqvarna 155 Rider (articulated) with something other than a commercial ZTR. I am looking at the Gravely 1440 Hydro RER model with the 40" deck. My total lawn area is between 3/4 and one acre. I use a New Holland tractor and a Bush Hog finishing mower in the pastures but it is too heavy and cumbersome for my lawn areas. BTW -- the Husqvarna rider is most certainly not engineered to handle US lawns. Way too fragile and unreliable. Thank you.
