A grounds maintenance system comprising: a robot tractor comprising; a robot body; a drive system including one or more motorized drive wheels to propel the robot body; a control system coupled to the drive system, the control system configurable to store a mow plan that specifies a set of paths to be traversed for a grounds maintenance operation and control the drive system to autonomously traverse the set of paths to implement the mow plan; a battery system comprising one or more batteries housed in the robot body; and a low-profile mowing deck coupled to the robot body, the mowing deck adapted to tilt and lift relative to the robot body, wherein the control system is configured to control tilting and lifting of the mowing deck and cutting by the mowing deck.

Aspects relate to an autonomous ground working vehicle. The vehicle has a chassis, wheels coupled to the chassis, a motor housing coupled to the chassis, a tool motor, and a tool. The motor housing defines a motor cavity extending in an axial direction and has a first inner housing portion having a first helical thread about the motor cavity and a second inner housing portion having a second helical thread about the motor cavity that engages the first helical thread. The first inner housing portion has a motor mounting surface and is axially translatable relative to the chassis and rotatably fixed relative to the chassis. The second inner housing portion is rotatable relative to the chassis and axially fixed relative to the chassis. The tool motor is fixed to the motor mounting surface and has an output shaft extending in a first direction. The tool is fixed to the output shaft.

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 mower conditioner implement includes a cutting system for cutting crop material, and a crop conditioning system for receiving the cut crop material from the cutting system and conditioning the cut crop material to facilitate drying. An image sensor senses an image of the cut crop material. The image includes a color spectrum of the cut crop material from reflected light emitted from a light source. A computing device compares the color spectrum of the image to a calibrated color measurement to determine an ash content in the cut crop material, and/or a degree of stem conditioning of the cut crop material. The computing device may then communicate the results to an operator, and/or adjust the cutting system or the crop conditioning system based on the ash content or the degree of stem conditioning.

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.

Outdoor power equipment includes a frame, a power head, a hydrostatic transmission, a pair of rear drive wheels, a drive chain, and a wheel height adjustment mechanism. The hydrostatic transmission includes a drive gear configured to rotate about a first axis. The pair of rear drive wheels are coupled at respective ends of a rear drive axle, wherein the rear drive axle is operably coupled to a driven gear. The pair of rear drive wheels, the rear drive axle, and the driven gear are configured to rotate about a second axis. The drive chain is operably coupled to both the drive gear and the driven gear. The wheel height adjustment mechanism includes a first bell crank pivotally coupled to the frame about the first axis, with a first end of the first bell crank being coupled to the rear drive axle.
