An agricultural machine including at least one working tool which can be driven by a drive mechanism which can have a variable drive speed, at least one movable shield which can be moved at least between operational and non-operational positions, and a device for moving the at least one shield, including at least one adjusting actuator and a device for locking the shield. The movement device includes a circuit for controlling the actuator which includes the locking device, which circuit automatically converts a variable input quantity into a control quantity which can adopt a first control value used to prevent the adjusting actuator from being moved out of a first configuration, the input quantity being a value which is a function of or dependent on the drive speed of the drive mechanism or on the working speed of the at least one tool.

The invention comprises a chassis rail comprising an elongate frame member having a first end for mounting a head pulley and a second end for mounting a tail pulley; a first plurality of spaced-apart apertures to allow visual inspection of a plurality of bed rollers; and a second plurality of spaced-apart apertures to allow visual inspection of a plurality of return rollers.

A cutting unit for a disc harrow and/or a seed coulter. The cutting unit includes a cutting blade rotatably mounted about a rotation axis, and a stripping device for stripping earth accumulated on the cutting blade, wherein the stripping device has at least one stripping arm rotatably mounted about the rotation axis.

A leaf screen cleaner system to remove crop material such as leaves and stalks from one or more leaf screens of a combine harvester, the system including a slotted carriage movable in opposing directions, a screen having plural members, each of the plural members disposed in a respective slot of the carriage. A pulley assembly is coupled to the carriage and a feeder house is coupled to the pulley assembly. Based on pivotal motion of the feeder house, the carriage moves relative to the screen along the plural members.

An agricultural tillage implement has a disk frame assembly connected to a pull hitch extending in a travel direction with frame members extending generally laterally with respect to the travel direction. At least one disk blade is connected to and supported by the frame members to till soil over which the agricultural tillage implement traverses. A disk scraper mounting member is connected to at least one frame member. A channel shaped disk scraper is connected to the disk scraper mounting member using a bolted joint connection. The channel shaped disk scraper has a square mounting end adjoining an inner perpendicular surface of the disk scraper mounting member. The channel shaped disk scraper is operable to scrape residue from the at least one disk blade and deflect it away from the travel direction.

A system for detecting material accumulation relative to basket assemblies of an agricultural implement includes a frame assembly, and a basket assembly configured to be supported by the frame assembly relative to a surface of a field. The system also includes a load sensor configured to detect a load indicative of a draft load associated with the basket assembly, and a computing system communicatively coupled to the load sensor. The computing system is configured to monitor the load based on data provided by the load sensor, compare the monitored load to a load threshold, and determine that field materials have accumulated relative to the basket assembly when the monitored load differs from the load threshold.

A safety guard for a power take off (PTO) shaft including a guard body for positioning over the PTO shaft, and a U-shaped locking clip. The clip is slidable in a radial direction with respect to the PTO shaft, between the locked and unlocked positions. The locking clip includes a pair of locking portions that each extend into an annular groove present on the PTO shaft or present on a guard bearing member mounted to the PTO shaft when the locking member is in the locked position to prevent axial displacement of the guard body relative to the PTO shaft.
