  • Patent number: 12114597
    Abstract: A latching assembly (100?, 100?) for operably coupling a cutting deck (50) to an equipment frame (60) of a riding lawn care vehicle (10) may include a pivot arm (300, 400), and a latch member (310, 410). The pivot arm (300, 400) and the latch member (310, 410) may each be pivotally coupled to each other. The pivot arm (300, 400) and the latch member (310, 410) may also cooperate with each other to affix the cutting deck (50) to the equipment frame (60) in each of a service position and a working position.

  • Patent number: 11259461
    Abstract: A riding lawn care vehicle may include a frame to which a mobility assembly is operably coupled, an equipment frame operably coupled to the frame forward of the mobility assembly, a steering assembly operably coupled to the mobility assembly to enable an operator seated on the riding lawn care vehicle to provide steering control of the riding lawn care vehicle, a removable cutting in deck and a belt positioning system. The cutting deck includes a rotatable blade and is configured to receive power for turning the blade from an equipment drive belt of the vehicle when the equipment drive belt is operably coupled with the cutting deck. The belt positioning system is configured to enable the equipment drive belt to be automatically operably coupled between the cutting deck and the riding lawn care vehicle in response to the cutting deck being docked with the equipment frame in an operational position.
