Guys,
The price difference is pretty significant between the various tread patterns. The knock on the Turf Mates was that with heavy use the tires would wear out quickly. In terms of traction they generally recieved good marks unless the tread became backed with debris such as mud.
The AS model is simply a Lazer with out all the bells and whistles. Like all Exmark product it too has a lot of bang for the buck.
Thanks,
Terry
