The dual applicator machine may also include a dry product tank and a dry product meter system in fluid communication with both the dry product tank and a dry product delivery tube.

An apparatus for facilitating maintaining of lawns. The apparatus comprises a body, wheel assemblies, and a material spreading assembly. Further, the material spreading assembly comprises a bottom container, a top container, a control mechanism, and a spreading mechanism. Further, the bottom container defines a bottom chamber including a first inlet and a first outlet. Further, the top container defines a top chamber including a second inlet and a second outlet. Further, the top container transfers a material received into the top chamber to the bottom chamber. Further, the bottom container dispenses the material received in the bottom chamber through the first outlet. Further, the control mechanism is coupled with the top chamber and allows the transferring of the material with a transferring rate. Further, the spreading mechanism is disposed in the bottom chamber for dispensing the material received in the bottom chamber through the first outlet in a dispensing area.

A control system is operable to control an autonomous machine for autonomously applying one or more products to a jobsite in accordance with a set of operation instructions. The products are stored in one or more interchangeable containers which are initially located on a station. The control system broadly includes an alignment sensor and a machine processor. The alignment sensor is configured to sense and generate alignment data regarding a relative position of the station and a particular container that contains a particular product. The machine processor is configured to align the autonomous machine with the station and the particular container based on the alignment data from the alignment sensor, and transfer the particular container from the station to the autonomous machine; move the autonomous machine over the jobsite and apply the particular product from the particular container in accordance with the set of operation instructions; and align the autonomous machine with the station based on the alignment data from the alignment sensor, and transfer the particular container from the autonomous machine to the station.

An agricultural vehicle includes: a chassis; a tank carried by the chassis; at least one meter module coupled to the tank, the at least one meter module having at least one gate; a gate control link coupled with the at least one gate of the at least one meter module; a control rod carried by the chassis; and a connector coupling the control rod to the gate control link at a connection interface such that movement of the control rod controls an open state of the at least one gate of the at least one meter module, the connector having a frangible portion adjacent the connection interface, the control rod and the gate control link uncoupling from one another upon a breaking force causing the frangible portion to break.

A clutch assembly configured to selectively engage and disengage a power source and a transmission includes an input member configured for coupling to the power source and an output member configured for coupling to the transmission. A clutch pack is engaged with the input member for co-rotation about an axis. A housing is engaged with the output member and with the clutch pack and is further configured to move in a first direction along the axis and in a second direction opposite to the first direction. The clutch assembly includes a cover and a ring member positioned along the axis from the cover such that the cover and the ring member define a movable chamber therebetween configured to receive a hydraulic fluid. The clutch pack is operable to decouple the input member from the output member in response to a pressure of the hydraulic fluid within the chamber.

A seed cart coupler system for providing efficient connection of air seeder hoses between a seed cart and air seeder with a corrosion resistant coupler. The seed cart coupler system generally includes a first connector adapted to be removably connected to a second connector. The first connector includes a plurality of tubes that fluidly connect to corresponding seed hoses of a seed cart and the second connector includes a plurality of tubes that fluidly connect to corresponding seed hoses of an air seeder. The first connector and the second connector fluidly connect the seed tubes of the seed cart and the air seeder when connected together. The first connector and the second connector are preferably constructed of a material that is not corroded by fertilizer.

The disclosed apparatus, systems and methods relate to fluid distribution systems. The fluid distribution systems being made up of a plurality of positive displacement pumps disposed on a fluid distribution manifold and proximate to the tank and the point of product discharge. The system optionally has a valve system for precision control of fluid discharge.

An agricultural machine, in particular self-propelled and/or towed agricultural machine and methods for proactively controlling an agricultural machine to maintain a positioning of a boom coupled to the machine over uneven terrain are described. The agricultural machine includes a chassis that bears components of the agricultural machine, a data processing apparatus, a sensor unit for detecting an inclination angle of the chassis relative to a reference plane, and a detection apparatus for detecting a travel speed and/or a travelled route, per time unit. Proactive control of the machine is achieved using the data processing apparatus which is configured to calculate a travelled route, in particular per time unit, using a travel speed and/or to calculate a terrain relief using a travelled route, per time unit, and using an inclination angle of the chassis which changes or remains constant along the route.
