I bought the Turf Master this year. Here are my though on it.
1. Needs a bigger engine on it. Bogs down to much in wet grass or tall grass. I was warned about this at the dealer.
2. Don't have any problems on hills. It is heavy and does take a bit to get it going sometimes, but other than thatn its great on hills.
3. Its a heavy beast but once you get used to it, its not to bad. Its very balanced.
4. I use this mower and a 21 inch. This mower compared to a 21 inch, much better. We have one place we cut and its done so much faster now. Saving me time.
5. I only use the mulch so I'm not sure how the bagger/side discharge are.
Id buy another one. My only complaint is that it needs a bigger hp on it. It should bog down as easy as it does.
