A device for trimming around stationary objects is disclosed as a rotary mowing attachment with a cutting head assembly slidably coupled to a carrier assembly that is positioned by a slope control circuit and controller. The cutting head assembly has at least two counter-rotating blades, at least one rotator motor configured to rotate the cutting head assembly about a cutting head central axis, at least one blade drive motor configured to drive the at least two counter-rotating blades, and at least one lateral motion drive motor configured to move the cutting head assembly position relative to the carrier assembly.

Mowing systems include a mower and a remote control unit such as a handheld unit, between which is provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to an enable switch on the remote control unit that requires activation within a specified time before activating a drive system or PTO unit. Another aspect relates to sharing diagnostic information between the mower and remote control unit and emitting user-detectable warnings in response to the shared information. Another aspect relates to reducing a danger level of the system, e.g. disabling the PTO unit or slowing a drive speed transform function, when a proximity between the mower and the remote control unit is too small. Another aspect relates to controlling operation of the mower based on tilt angles of both the mower and the remote control unit.

A wide area mower with an open-box structure mower deck. The deck has a width from the left to right side of about 72 to 120 inches. The deck's length is about 24 to 70 inches. A left and right front wheel are positioned in front of the deck. The wide mower deck will flex, twist, or bend when one of the left or right wheels travels over uneven terrain while the rest of the mower travels over substantially level terrain. A cutting height adjustment mechanism is provided on the mower that allows an operator to raise or lower an entire left side or an entire right side of the mower deck to a selected cutting height. This is done simply by disengaging a locking mechanism and manipulating a lever on a four-bar linkage attached to each side of the deck and then re-engaging the locking mechanism.

A mower assembly adapted to be coupled to a hitch of a work machine. The mower assembly has a sub-frame with one or more hitch couplers adapted to be removably coupled to the hitch of the work machine, a mower arm having a first end and a second end, the first end being pivotally coupled to the sub-frame with a pivot pin, the mower arm is pivotable about the first end between a first position and a second position relative to the sub-frame, an arc-shaped rail positioned about the pivot pin for guiding the mower arm as the mower arm transitions between the first position and the second position, and a mower head mechanically coupled to the mower arm at the second end.

A grass mower includes a frame that extends in a front/rear direction of a machine body, a mower deck supported to/under the frame, the mower deck extending in a transverse direction of the machine body, a side edge of the mower deck protruding laterally from the machine body, a tilt detector for detecting a rolling angle of the machine body, a display device for displaying the rolling angle, a first informing device for effecting a first informing for calling attention to grass scraping by the side edge when a rolling angle detected by the tilt detector exceeds a first tilt angle and a second informing device for effecting a second informing for calling attention to traveling danger when the rolling angle detected by the tilt detector exceeds a second tilt angle.

There is configured a work machine whose engine and fuel tank will not be damaged at time of a work even when the engine and the fuel tank are arranged with offset to one side in the left/right direction of the machine body. The work machine includes a machine body that can travel with left and right front wheels and left and right rear wheels and an implement supported to the machine body. An engine driving the front wheels, the rear wheels and the implement and a fuel tank are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine body. There is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction of the fuel tank.

A cutter for use with a mower such as a front of a tractor or skid steer has at least one cutting blade disposed below a cutting deck. A first arm assembly connects at a pivot to the deck and preferably connects to an extension extending forwardly relative to a mounting plate connected to the mower. The pivot is preferably spaced by a portion of the arm assembly from a length of the mounting plate. A roller assembly may be utilized to support the cutting blades above a surface to be cut. A second arm assembly may selectively position the cutting deck at preselected angles about the pivot. The first arm assembly may have curved ribs to allow the cutting deck to be declined to a negative angle relative to the pivot.

A mower combination including an agricultural vehicle and a number of mowing units suitable for cutting standing crop, including a front mowing unit and two lateral mowing units located behind and to the sides of the front mowing unit. Each of the lateral mowing units includes a conveyor to deposit cut crop as a swath. Sensors determine the slope and lateral displacement of each conveyor. A control unit receives inputs from the sensors and compares the inputs to a predetermined set of values of slope and, as indicated by the comparison, adjusts the lateral displacement of at least one conveyor.
