Abstract: A grass mower comprising a power generator, a blade reel, a drive drum, and a power split device. The split power device can include a single power input shaft, a reel output shaft, a drum output shaft, and at least one continuously variable transmission hub operably connecting the reel output shaft and/or the drum output shaft to the power input shaft such that torque and rotational speed delivered by the power input shaft is transferrable to the reel and/or drum output shafts at any infinitely variable ratio. The power split device structured and operable to transfer the torque and rotational speed delivered by the power input shaft to both the reel and drum output shafts such that a rotational speed of the blade reel and a rotational speed of the drive drum are both generated from the power delivered by the power input shaft and are both independently controlled.

Abstract: A bi-directional drive system for turf grooming and brushing operations is provided. In various embodiments, the system includes a reel deck assembly having a reel blade assembly rotatably supported on a reel blade shaft axially rotatable in a reel blade shaft rotation direction. The system additionally includes a first positive engagement member rotatably connected to the reel deck assembly, and an attachment member releasably connected to the first positive engagement member. The attachment member is simultaneously axially rotatable in an attachment member first axial rotation direction that is the same as the reel blade shaft rotation direction, or an attachment member second axial rotation direction opposite to the reel blade shaft rotation direction. The bi-directional rotation is implemented by selective engagement of a drive system connected to the reel blade shaft.

Abstract: A bi-directional drive system for turf grooming and brushing operations includes first and second accessory attachment assemblies connected to a reel deck assembly. A first drive housing connected to the first accessory attachment assembly has a first positive engagement drive member rotatable with respect to the first drive housing. A second drive housing connected to the second accessory attachment assembly has a second positive engagement drive member rotatable with respect to the second drive housing. An attachment member is releasably connected to each of the first and second positive engagement drive members and axially rotated in either a first or an opposite second axial rotation direction. First and second fasteners individually received through one of the first or second positive engagement drive members releasably couple the attachment member to the first and second positive engagement drive members. Attachment member removal is provided by releasing only the first and second fasteners.
