Electronic control for a grass cutting reel assembly of a lawn-care vehicle

摘要

A system for controlling a grass cutting reel assembly of a turf-care vehicle. The system includes: a reel cylinder motor operable to rotate a reel cylinder of a grass cutting reel assembly of a turf-care vehicle at a desired rotational rate of speed to provide a controllable frequency of clip for the reel assembly; an automated height of cut control system operable to control a position of a front roller of the reel assembly to provide a controllable height of cut for the reel assembly; and a controller system operable to control the reel cylinder motor and the height of cut control system to provide a particular frequency of clip and a particular height of cut stipulated by one of a plurality of cutting scenarios programmed into the controller system and selected via a user interface of the controller system that is accessible by an operator onboard the turf-care vehicle.

1. A control system for a grass cutting reel assembly of a turf-care vehicle, said system comprising:
a reel cylinder motor structured and operable to rotate a reel cylinder of a grass cutting reel assembly of a turf-care vehicle at a desired rotational rate of speed that is based on the terrestrial speed of the vehicle to provide a controllable frequency of clip for the reel assembly; an automated height of cut control system structured and operable to control a position of a front roller of the grass cutting reel assembly to provide a controllable height of cut for the reel assembly, wherein the automated height of cut control system comprises:
a cam shaft rotationally mounted within a reel frame of the grass cutting reel assembly; anda pair of eccentric cams mounted to opposing ends of the cam shaft and structured and operable to interact with a front roller frame pivotally connected to the reel frame and having the front roller rotationally disposed therein, such that rotation of the cams will controllably move the front roller frame and thereby control a position of the front roller relative to the reel cylinder and thereby control the height of cut; and a controller system structured and operable to, via a one-touch process, control the reel cylinder motor and the height of cut control system in accordance with a selected one of a plurality of cutting scenarios, selected via the one-touch process, wherein each cutting scenario stipulates both a particular frequency of clip and a corresponding particular height of cut to be implemented by the reel assembly, each cutting scenario programmed into the controller system and selected via the one-touch process using a user interface of the controller system that is accessible by an operator onboard the turf-care vehicle.
