I 'was' looking at a 'garden' type tractor. The reason being is I live in the mountains, so to speak, and my 1/2 acre of mowable area needs a machine that can handle the inclines.
I have a mostly level yard with some steep areas. One area is a driveway cut through a bank from the highway. I couldn't mow it with a compact tractor and finishing mower. It would slide down the slope, and there was a ditch at the bottom. Going across the slope would have been suicide. With a push mower, even it would turn up on its side when mowing across the slope. Needless to say, this slope is well over 15 degrees. It is difficult to walk up. From construction work, I don't think of slopes in degrees, but in the rise ratio. This slope approaches a 2:1 (one foot of rise per 2 feet of horizontal distance). Cars, trucks, mowers, and tractors handle 3:1 slopes with caution.
I bought a Cub Cadet Zero Force 60" with steerable front wheels. It sits on the slope well and climbs it with no difficulty. While other zero turns might also sit and climb as well, the problem is the front wheels. On steep slopes the uphill drive wheel loses traction, and the caster wheels of most zero turn mowers "go with the flow." On the Cub, the front wheels allow me to turn with confidence up the slope without worry about losing traction. (I also slide the seat forward and tilt the steering wheel upright to put more weight on the front.)
