There are included front and back slope portions attachable to and detachable from storage positions and use positions, front and back holding portions capable of engaging with engagement portions of the front and back slope portions as attached to the storage positions and holding the front and back slope portions at the storage positions, and a disengaging operation tool capable of being manually operated to a disengaging position at which the front holding portion and the back holding portion are releasable from the engagement portions of the front and back slope portions and at which the slope portions are detachable from the storage positions.

A lawnmower cutter assembly (22) comprises a knife carrier arrangement (26) and a skid plate arrangement (30), which are axially held between an axial stop shoulder (60) of the cutter drive shaft (34) and an end piece (54) rigidly connected to the cutter drive shaft (34), the end piece (54) thereby vertically carrying the skid plate arrangement (30) and the knife carrier arrangement (26). The cutter assembly (22) may be attached to a lawnmower, which may be a robotic lawnmower, by positioning the knife carrier arrangement (26) and the skid plate arrangement (30) on the cutter drive shaft (34); and thereafter, axially locking the axial position of the knife carrier arrangement (26) and the skid plate arrangement (30) in relation to the cutter drive shaft (34).

A lawn mowing apparatus may include sensors that are fastened to both its mower deck and its chassis. The sensors may sense a position of the mower deck in relation to the chassis. The sensed position of the mower deck may be presented to the operator via a dashboard display of the lawn tractor or transmitted via a wireless signal to another device. Based on such sensed position, an operator of the lawn tractor may manually adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable operating range. In some embodiments, servomotors may used to adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable range.

A grass mowing machine includes a vehicle body frame, a mower deck incorporating a rotary cutter blade, a coupling mechanism for coupling the mower deck to the vehicle body frame with allowing a lateral displacement of the mower deck in a vehicle body transverse direction, a mower electric motor attached to the mower deck and configured to feed rotary power to the rotary cutter blade and a displacement operation mechanism MV for laterally displacing the mower deck in the vehicle body transverse direction in operative association with the coupling mechanism.

There are included a passage portion provided at an upper surface portion of a mower deck, front and back slope portions and provided at front and back portions of the passage portion, front and back supporting portions supporting the slope portions in such a manner that the slope portions are movable in the front-back direction and swingable in the up-down direction, and front and back linking portions that are supported in such a manner as to be swingable in the front-back direction about axes extending in the left-right direction and that are connected with the slope portions. Operating the front and back linking portions in the front-back direction causes the front and back slope portions to be operated to the storage and use positions.

A grounds maintenance vehicle has a vehicle frame defining a column opening having a first end and a second end. An implement is coupled to the vehicle frame. A height adjustment column has a base and distal end, where the base is fixed to the implement. The distal end of the height adjustment column extends through the column opening from the first end beyond the second end. The height adjustment column defines a first locking structure and a plurality of height setting locations. A height selection tool is couplable to the height adjustment column and is translatable to each of the plurality of height setting locations. A second locking structure is coupled to the vehicle frame, where the second locking structure is configured to releasably engage the first locking structure such that the plurality of height setting locations are positioned beyond the second end of the column opening.

A mowing machine may include a central cutting deck generally disposed in a neutral mowing plane and a wing cutting deck pivotable with respect to the central cutting deck. A main gearbox may be connected to a wing gearbox by a wing driveline. The main gearbox may be disposed a sufficient distance forward of the central cutting deck and the wing cutting deck to permit the wing cutting deck to pivot about a hinge in a range of motion without disconnecting the wing driveline from either the main gearbox or the wing gearbox.

A mounting mechanism (100), to enable hitching a tool (101) with the frame of a utility vehicle, comprises front hooks (102), a locking mechanism (104), a lifting cradle assembly (106), and a frame attachment mechanism (108). The front hooks (102) and the locking mechanism is configured to detachably engage the front and the rear portion of the tool (101) respectively. The cradle assembly (106) is configured to be operatively engaged with the front hooks (102) and the locking mechanism (104). The frame attachment mechanism (108) is configured to be pivotally coupled to the lifting cradle assembly (106). The locking mechanism (104) is configured to be operated by lifting the cradle assembly (106) via pivotal motion between the cradle and the frame attachment mechanism (108) under force generated by the vehicle (1000) to hitch and lock the tool (101) with the frame of the vehicle (1000).

The present disclosure relates to a robotic lawnmower cutting deck (130) comprising a cutting system (131) which in turn comprises at least two cutters (132a, 132b, 132c), with a cutting disc (133a, 133b, 133c) and cutter motor (134a, 134b, 134c). The cutters (132a, 132b, 132c) are supported by a cutter support beam (135) which has a longitudinal beam extension (L1) and in turn is supported at respective supporting positions (135a, 135b) by a corresponding first link arm (136a, 136b) and a corresponding second link arm (137a, 137b). At each supporting position (135a, 135b): the link arms (136a, 136b; 137a, 137b) are pivotingly attached to the cutter support beam (135) with a corresponding first pivot pin (138a, 138b) and second pivot pin (139a, 139b) that are fixed relative each other, the link arms (136a, 136b; 137a, 137b) are pivotingly attached to a frame part (140a, 140b) with a corresponding third pivot pin (141a, 141b) and fourth pivot pin (142a, 142b), the third pivot pin (141a, 141b) and fourth pivot pin (142a, 142b) have an adjustable relation relative each other such that the cutter support beam (135) is rotated (R) around the longitudinal beam extension (L1) when the relation between the third pivot pin (141a, 141b) and fourth pivot pin (142a, 142b) is adjusted.
