Currently we cut around 8 acres it is all hills and lots of trees. I bought a zero turn Lastec with a 33 hp engine. I would love this mower if I had flat grounds, the slopes just make it tough. The tires will also make more, than I like, ground disturbance shredding grass and soil leaving bare spots. How will the Ventrac do in tight circles. I would probably have the dual wheel set up. The articulated front mower would be the mower of choice. I may be forced to use two mowers one for narrow for semi trim work and the other wider cut for more open area. Can single tires be turf and then add the knobbies on for traction when double? Each corner would have one turf and one knobby. How much difference is there in ground disruption between the turf and the knobbies. Input on tight turns and gro If anyone knows of a dealer that would accept a trade in please advise, I am in southwestern Indiana.
