A mower includes: driving devices respectively provided on a right side and a left side of the mower and configured to be driven independently; and one or more processors configured to: estimate a gradient of a slope on a travel path; and drive the driving devices with different driving forces on the right side and the left side based on the estimated gradient such that the mower does not slip down the slope when the mower travels in a direction crossing the slope.

A disc mower for cutting crop material includes a plurality of cutter assemblies attached to a frame. Each of the cutter assemblies includes a respective motor operatively attached to a respective disc for rotating the disc. A cutter controller is operatively coupled to the respective motor of each of the plurality of cutter assemblies for selectively controlling a respective commanded rotational speed of the respective motor of one of the cutter assemblies independently of the respective commanded rotational speed of the respective motor of another of the cutter assemblies. Each of the individual cutter assemblies may be vertically moveable relative to the frame independently of the other of the cutter assemblies.

An agricultural mowing device that includes a tongue configured for connecting to an agricultural vehicle, a trail frame, first and second trail-frame wheels, first and second lift actuators for lifting the trail frame, a trail-frame actuating mechanism operably connected in between the tongue and the trail frame and configured for rotating the trail frame, and a transport system. The transport system includes a transport frame, first and second transport wheels, and a transport actuating mechanism rotatably connecting the transport frame to the tongue. The transport actuating mechanism includes a transport actuator operably connected in between the tongue and the transport frame and configured for rotating the transport frame.

A harvesting header includes a header frame, rotary cutters carried by the header frame, a gearbox containing at least one gear coupled to each rotary cutter, and an electronic sensor to indicate an amount of oil in the gearbox. Each rotary cutter has a rotating disc with at least one blade for cutting crops. An agricultural vehicle includes a vehicle frame, at least one attached to the vehicle frame, and a harvesting header coupled to the vehicle frame by a plurality of hydraulic cylinders. A method of operating an agricultural vehicle includes adjusting at least one hydraulic cylinder to move a header frame to a known orientation, sensing a position of an oil surface in a gearbox, and determining or indicating an amount of oil in the gearbox based at least in part on the position of the oil surface.

A mower deck insert includes a first cutting chamber, a second cutting chamber, and a discharge passage extending adjacent to the first cutting chamber and the second cutting chamber. The first cutting chamber includes a first axial scroll extending about a first vertical axis. The first axial scroll includes a first upper surface having a first start region and a first end region. The second cutting chamber includes a second axial scroll extending about a second vertical axis. The second axial scroll includes a second upper surface having a second start region and a second end region. The first start region is vertically lower than the first end region, and the second start region is vertically lower than the second end region.

An agricultural machine includes a hitching support, at least one tool or group of tools that can be transferred between an operational position and a raised position, at least one support arm that is connected to the hitching support via two joints and to the tool or group of tools at an assembly location, and a safety device for performing a safety movement under the effect of pressure. At least one first safety movement phase is carried out around the first joint or around one of the two joints. The safety device includes at least one guiding device to allow for a variation in a distance between the other of the two joints and the assembly location when the rearward rotation is carried out around the first joint.

A high-efficiency cutting system for an autonomous mower provides a multiple blade tip cutting radius for a cleaner cut, and more complete mow. The system includes a spinning blade disk provided within a housing including a vertical standoff. The blade disk includes a first pair of cutting blades located between the center of the blade disk and the circumference of the blade disk, and a second pair of cutting blades located radially inward from the first pair of cutting blades. The cutting blades extend downward and away from the blade disk at an angle.

A mower which may include: an engine for driving at least first and second cutting blades, wherein the first and second cutting blades are located in first and second cutting chambers of the cutter deck structure, wherein the cutter deck structure may include an inclined surface in the first cutting chamber so that at least part of the inclined surface is located closer to the trim side of the cutter deck structure than is any cutting blade rotational axis, the inclined surface extending downwardly from an upper surface of the cutter deck structure toward at least the trim side of the cutter deck structure, wherein the inclined surface slopes downwardly from the upper surface in a direction away from the side-discharge opening; wherein the inclined surface is configured to help provide a high pressure zone within a rear portion of the cutter deck structure and a low pressure zone proximate the trim side of the cutter deck structure for helping vegetation to be cut to be pulled into the first cutting chamber.

A mowing machine has a cutterbar oriented transverse to a travel and working direction of the mowing machine and provided with first and second ends spaced apart from each other in longitudinal direction. First cutting members are rotatably mounted on a top side of the cutterbar and rotatably driven about a vertical axis by a drive assembly within the cutterbar. A joint and drive assembly is connected to the first end of the cutterbar. A lateral cutterbar section is connected to the joint and drive assembly and has a second cutting member driven by the joint and drive assembly. The joint and drive assembly has first and second holding elements mounted relative to each other such that pivoting of the lateral cutterbar section in a cutterbar plane of the cutterbar is enabled. The first and second holding elements are arranged in planes positioned at a minimal spacing above each other.
