I am a homeowner with 4+ acres with many banks, hills and ditch lines. After looking at several ZTRs with an emphasis on hill abilities I narrowed down my choices to Yard Shark and Country Clipper Charger. I chose the Charger because in my opinion it was more machine for less money. I wasn't able to try them both on the same hill but contrary to most comments on LawnSite.com, it appeared that the Shark was actually slightly better on hills than the Charger. The dealer took the Shark across a hill steeper than I would even attempt and the only time is slipped was on a rough section that was rocky and had little grass. But the Charger is very good on hills and more than adequate for my needs. The design of the Shark is very simple and the deck is rock solid. However the deck simply isnt deep enough in my opinion. The Charger deck has excellent discharge even in wet conditions and has a clean cut. The flip out deck is a nice design, and is quicker and easier to do than I expected. My only complaint about the deck is the deck hangers are very noisy over rough areas. My only other complaint is the seat. The Shark has a Michigan seat standard and one should be on the Charger. I havent tried every ZTR out there but of the ones I tried, the Shark and the Charger were hands down the best performers on hills. The Charger is a heavier machine with a better deck and that is why I chose the Charger.
