I mow about 2.5 acres and it is also pretty rough (not country club) mowing. This is the best machine that I have ever been on even in the wet seasons. As we have stated here, there is no 4wd in reverse so you have to be careful not to nose into a mud pit with an obstacle in your way. The State of NY uses these machines in their parks and some of those are pretty rough terrain.
I found mine on Craigs List, a High School in Newark NY was trading up and I bought one of two that they had.
As a point of reference I bought mine, (a 2006 with 1200 hrs.) in 2015, they wanted $6,500 and I got it for $5,500. There are individuals asking crazy money for these but, you can find deals if you have patience. I like buying from an institution since money seems to be no object when it comes to maintenance, actually most of these are not in private hands anyways.
These have no suspension except for the seat and will bounce a bit in the rough stuff but, they have quite a bit of weight to temper the bumps and they do not rock back/forth like a zero turn.....Mike.
PS these also come in 2wd so look for the hoses to the rear wheels if you want 4wd.
