I'm in the market for a ZTR to start the season off next year. Had never used one except for driving a friend's around a parking lot. This was the Lesco Zero-2 60". That's the only size they had as a demo. I currently have two 48" exmark walk-behinds. My original thinking was to get a 48" ZTR so I could mow with either and stripes would be the same and it wouldn't scalp like a bigger deck, but the deck did better than I expected for a 60" on some of the uneven areas. There were places where the walkbehinds dig in where this went right over and didn't even scalp. My bigger properties are around 1 acre and I saved about 15 minutes with the 60" ZTR over the 48" walk behind. I guess my next question is how much of this is because of the speed of the ZTR and how much is because of the inches. I guess I need to try a 52" and a 48" ZTR on the same properties and compare. What are your suggestions??
