Abstract
A high efficiency turf maintenance apparatus having low power consumption and good cutting performance is presented herein. A multi-blade blade assembly is disclosed to reduce power consumed in driving the blade assembly and enhance longevity of a dischargeable power supply. In some aspects described herein, a first blade of the multi-blade assembly can have a first length that is greater than a second length of a second blade. Further, the first blade or the second blade can be substantially bilaterally symmetric about a rotation axis of the multi-blade assembly. In alternative or additional aspects, the second blade can provide lift within a deck of the high efficiency turf maintenance apparatus to propel turf clippings from within the mow deck through a discharge opening therein.
