I am new to this forum and to ZTR. Just upgraded from a John Deere GX345 to a Gravely ZT HD 60 inch. Still learning to drive it, but it is much more fun than the JD. It has cut my mowing time from 6 hours to a bit over 4. Yes, I live on a farm and have a large area to mow. Only problem had so far with the ZTR is traction. Gravely does not offer an aggressive tread tire for this model. Turf tires DO NOT work for me. Have bar treads on my JD GX345. Had to do a search on the web and it took me days to find an aggressive tread that would fit. Just received the tires yesterday and so far am very pleased with them.
