I got the engine mounted to the 32" Bob-Cat sunday afternoon. I got home today to start the mowing on my yard and my grandma next door. Usually takes me 4-5 hours (she has an incredible amount of obstacles and hills), Got done in 2 hours including several smoke breaks! I didn't even realize what time it was and was looking for more grass to cut! I'd been using a lawn rider and a small push for the hills. If this is any sign, a hydro WB will be even better. I used to use my smoke breaks thinking of new ways to attack the hills, now I'm thinking of ways to stripe them! The grass next to the road is the best because we got city water last year and they seeded it really good after laying the pipes. I mowed that first and could tell right away what a difference in cut this thing has. Didn't know what I was missing!
