摘要： A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

摘要： 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.

摘要： A riding mowing device includes a seat, a frame, a cutting assembly, a walking assembly, a power supply assembly, and a steering wheel assembly. The cutting assembly includes a cutting deck and a mowing element. The cutting assembly is mounted to the frame. The walking assembly is used for driving the riding mowing device to walk. The power supply assembly is used for powering at least the cutting assembly and the walking assembly and mounted to the frame. The steering wheel assembly includes a steering wheel for the user to operate and a support rod connecting the steering wheel to the frame. The riding mowing device further includes a mounting assembly including a locked position and an unlocked position, where when the mounting assembly is in the unlocked position, the steering wheel assembly is switchable between at least a first working position and a second working position.

摘要： An improved base cutter blade suited for use in a sugar cane harvester. The preferred improved blade has a generally elongated flat body with opposing longitudinal edges. A removable, replaceable knife is also provided. The knife is made to releasably engage the leading edge of the body. Thus, the knife will perform most of the cutting work and bear the brunt of the wear suffered by the blade. When the knife becomes dull, only the knife need be replaced, which can be done quickly. This will save a significant amount of time during harvest operations. It will also reduce the amount of material that is consumed in the form of worn out blades.

摘要： 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.
