An agricultural device associated with reduced tillage techniques in a field includes a frame and at least one mower module supported by the frame, the at least one mower module positionable to cut plant matter between adjacent crop rows in the field. The plant matter has penetrated a previously formed mat of at least partially crushed residual plant matter.

A slope mower includes a mower body, drive wheels, left and right mower decks and left and right support wheels mounted on support arms pivotally mounted to the mower body with hydraulic actuators acting on the left and right support arms to maintain the mower body vertical. An inclinometer measures the tilt angle of the mower body and a controller reads the angle and controls a leveling valve to supply hydraulic fluid from a supply line to the leveling actuator toward which the inclinometer indicates the mower body is leaning to move the mower body back to vertical. The system can be programmed to actuate a leveling actuator only when the detected tilt angle exceeds a minimum angle. Lockout valves can be actuated by the controller to block the flow of hydraulic fluid to or from both actuators if a maximum allowed tilt angle is exceeded.

Electric powered mower unit (1) comprising a frame (13) provided with connecting points (132) arranged for attaching the mower unit (1) to a tool-carrier (3) provided with an electric power unit (31), several cutting modules (11), each cutting module (11) being suspended vertically displacea-ble and non-rotatable in a cutting module guide (122) provided in the frame (13), charac-5 tensed in that each cutting module (11) comprises a cutting disc (111) and an elec-tric motor (112) powered by the electrical power unit (31), said cutting disc (111) being attached to a motor driving shaft (1121), and a actuator (121) forming a link between the cutting module (11) and the frame (13).

A mower assembly is provided for cutting around a post. A support structure supports the mower assembly in cantilever fashion. The mower assembly includes a plurality of mower units with each mower unit having a rotary blade. Two or more mower units cooperate to engage and cut around a post and, during the process, the entire mower assembly rotates about an axis enabling the mower units to encircle and efficiently cut grass and other vegetation about the post.

A mower for turf or lawn includes a frame for use on a tractor, or to form a structure of a trailer, and a plurality of cutting units, at least six, generally disposed side by side, each cutting unit including at least one roller for rolling on the ground. The mower includes lift means linking the cutting units to the frame and configured for articulating the cutting units between a mowing position and a non-mowing position. In the mowing position, the lift means are configured for pressing the cutting units against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers of the cutting units. The mower includes lateral articulated beams linking the cutting units. The beams are foldable inwardly and forwardly.

Methods of using a mower are provided. The methods include providing a mower having a plurality of cutting heads, a first driven wheel supported at a first end of the plurality of cutting heads, and a second driven wheel supported at a second end of the length of the plurality of cutting heads. In some methods, each cutting head of the plurality of cutting heads is at least one of pivotably connected or translatably connected to at least one other cutting head of the plurality of cutting heads. Some methods include driving the first driven wheel such that the mower pivots about the second driven wheel.

A radio-controlled mower has a frame, an engine unit, rolling bodies configured to move the frame over an area of ground, a central cutting unit, and side cutting units. The frame and the side cutting units are mutually movable.

A mower includes a frame, at least one cutting unit, and a lifting unit. The lifting unit is connected to the at least one cutting unit and includes a yoke assembly, a first arm assembly, a second arm assembly, and a third arm assembly. The yoke assembly is connected to the cutting unit. The first arm assembly is pivotably mounted to the vehicle frame about a first pivot axis. The second arm assembly is pivotably mounted to the first arm assembly about a second pivot axis and to the yoke assembly about a third pivot axis with the second pivot axis and third pivot axis being non-parallel to the first pivot axis. The third arm assembly includes a first end pivotally connected to the frame and a second end pivotally connected to the second arm assembly.

A pair of reel mower cutting unit steering limiters including a pair of pivoting members that may be independently pivoted between an engaged position providing a full range of steering of a reel mower cutting unit in a first direction on a vertical yaw axis, and a disengaged position reducing the steering of the reel mower cutting unit in the first direction. The maximum steering angle may be independently adjustable in each direction.
