An agricultural system with an agricultural harvester has a terahertz sensor. The terahertz sensor includes at least one a terahertz source disposed to direct electromagnetic radiation toward a harvest material of the agricultural harvester. A terahertz detector is disposed to detect the terahertz electromagnetic radiation after the terahertz electromagnetic radiation interacts with the harvest material. A controller is operably coupled to the terahertz detector and is configured to detect a harvest-related parameter based on a signal from the terahertz detector and to perform an action based on a detected parameter.

A chopper system for a sugarcane harvester comprises a chopper and a wear indicator. The chopper comprises a first chopper drum, a second chopper drum, and a timer. The timer has an operational configuration in which a first timer portion and a second timer portion are operatively connected to one another to coordinate rotation of the first and second chopper drums and a timing-adjustment configuration in which the first and second timer portions are operatively disconnected from one another allowing relative movement between the first and second timer portions and corresponding relative rotation between the first and second chopper drums to adjust a timing of operation between blades of the first and second chopper drums. The wear indicator indicates an extent of blade wear of the chopper upon adjustment of the timing of operation via the timer in the timing-adjustment configuration.

An agricultural cutting mechanism for use with an agricultural machine has a disk rotatable about an axis of rotation, a post secured to the disk, a blade, and a yieldable blade retainer. The blade is removably secured to the disk. The blade comprises a keyhole in which the post is positioned. The blade retainer is secured to the disk to move relative thereto between a blocking position blocking radially inward movement of the blade to the replacement position so as to maintain the blade in the use position and a service position releasing the blade to move radially inward to the replacement position for replacement of the blade with another blade. A blade for use with an agricultural cutting mechanism is also disclosed.

A lift apparatus is provided for use with a vehicle comprising a first frame and a second frame. The lift apparatus comprises a spindle, a bearing, a cylinder, a snap ring, and a bearing retainer. The spindle is configured to be attached to the second frame so as to extend therefrom in spaced apart relation to the first frame. The bearing is positioned on the spindle. The cylinder is configured to be attached to the first frame and is attached to the second frame to move the first frame relative to the second frame. The cylinder is positioned on the bearing such that the bearing enables movement between the spindle and the cylinder. The snap ring is attached to the spindle. The bearing retainer is positioned on the spindle between the snap ring, and the bearing retains the bearing on the spindle.
