OK, I demoed a Gravely 260Z and a Similar Toro ZTR. I really liked the Gravely. Now as I ponder my options, I see and demo a GD Super Surfer. It was amazing. I really liked how quick and agile it was. I have mostly large lots to mow. But several of them have lots of trees(one has a small orchard) By large I mean 1.5 acre residentials. I am also going to be bidding 4 apt complexs with large steep hills unknown degree on hills. Walk behind will do them just fine. However I would like to find a good overall mower. Which mower would you guys buy. Any questions, just ask. Not sure if I have you all enough info.
