<font color="red"> If you're just using it for mowing I'll second the ZTR opinion.
<font color="blue"> Unless your yard is basically like golf course smooth, you really don't gain anything with a ZTR mower. If the yard is bumpy, pitted etc. your better off with a rider.

There is fact that if you respect your body, you'll probably never run the ZTR any faster than a tractor. But I'll still maintain the number of obstacles is the deciding factor for a ZTR [ZT around obstacles means much less time on those areas] and pull behind implements the deciding factor for a garden tractor. Of course, if you don't have many obstacles and no implements, the lawn tractors are economical.
BTW I recently tried mowing at 9+mph with a ZTR over some rough areas....my body may not agree, but it sure was fun! /forums/images/graemlins/smile.gif
