I have finaly talked a good friend into buying a Z. The problem is that she has a very large open area, use to be a hay field, and it is not the smoothiest land. I have explained to her to demo as many units as she can and then compare to make her mind up. She had a john deere front mount dropped off and we all began to test it, but due to roughness you get beat half to death in the matter of minutes. She is planning to go with a 60" deck due to cost of a 72". Does anyone have any sugestions as to what will suit this situation best for comfort!!! She is currently mowing with a larger john deere utility mower with a 60" belly mower.
