I care for one large estate with moderately sloping land. I have been using a lawn tractor (46" deck) and mowing some slopes. The lawn tractor just bit the dust. Now I want to upgrade to small zero turn mower. Is the Ferris 1500 (48" deck) a good choice for stepping up. The suspension system would be nice as I hit some rough ground. Realistically, what kind of time savings should I expect and how much trouble will I have holding a stripe along a slope while I get used to hand controls. Anyone out there use a Dixie Chopper? How do they compare. I have good dealerships locally for Gravely, Ferris, John Deere and a smaller shop selling Dixie Chopper. The boss told me to find something around $5000. Any thoughts?
