From practical experience:
- 2wd GT, Carlisle Multi-Trac C/S turfs, 2-link chains, 54" wide bucket plus 5' back blade, 2250 lb gross weight,
- 4wd SCUT, Carlisle Multi-Trac C/S turfs, 47" bucket and 5' back blade, 2450 lb gross weight.
- 4wd CUT, R4s,. 53" bucket, 2600+ lb gross weight.
The GT is noticeably better in the traction department than either of the larger tractors, even with both cutting edges on the ground. The R4s can best be described as an exercise in extreme frustration.
Turf tires are a friction type tread, relying on the number of square inches, and the number of inches of tread block edge, of ground contact rubber for traction on the hard packed snow that is left when following a blower, blade, or bucket. Other types of tread rely on their ability to penetrate the snow and push it with the lugs for traction. Hard packed snow does not allow penetration.
Note that with sufficient rear end ballast, chains do not scuff concrete or asphalt because the tires don't break traction and spin when pushing reasonable depths of fresh fallen snow. My definition of a reasonable depth is 18" of 'dry' snow.
