I now have 3.5 hours on mine. I LOVE it. I have 5.5 acres of mostly woods. I have been reclaiming areas. I have cut brambles, scrub brush weeds etc. It works great, it also does a great job on my lawn! I have one area with a steep slope, and it also works far better there than I would have guessed.
It seemed far faster than I needed the 1st hour of operation, and very quick for the 2nd... Now at hour 3.5 I could handle another 2 mph.. I can cut more in an hour or 2 than I could in 6 with my DR. There are still a few places I will use the DR to I can get the tractor in and smooth them out but the DR will be getting far less use.
The suspension really does make rough ground comfortable. I am very pleased with the mower. I did throw the idler spring yesterday for the belt to the hydro pumps, but it was an easy fix. I think the dealer had it a bit too loose. I will probably get the solid front tires as well as I lost air in one, but I am not babying it.
I test drove a number of machines and for the terrain I have I am sure I got the right machine. I have the 52 inch deck.
