Abstract: A high efficiency turf maintenance apparatus having low power consumption and good cutting performance is presented herein. A blade configuration is disclosed to provide lift and to propel turf clippings from within a mow deck through a discharge opening therein. A discharge body can receive turf clippings at an input and direct the turf clippings to an output. A bagging apparatus can be coupled to the discharge body output for a bagging mode, a side-rear diverter can be coupled to the discharge body output for a discharge mode, and a mulching plug can cover the discharge body output for a mulching mode.

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.
