Other manufacturers hang their mower decks from the lawn tractor frame. As the tractor wheels negotiate hills and holes, so does the mower deck, regardless of the terrain under the blades – resulting in potential scalping and uneven cutting. Simplicity mower decks move independently from the lawn tractor for a vastly superior cut, and they ride on top of full-width rear rollers, which constantly move up and down, allowing the blades to maintain the precise cutting height selected by the operator. As the pivoting axle and the full-width rear rollers respond to changing yard contours, so does the mower deck. The result is less scalping or unevenness. When you add in Simplicity’s computer-optimized airflow and super-sharp blades, you get the best cut on the block.
