A hydraulic system for a machine includes an implement pump, a valve, and an implement valve subsystem. The implement pump includes a load sensing control, and the valve controls the flow of hydraulic fluid to the implement pump. The implement valve subsystem includes one or more implement control subsystems to control movement of an implement. The valve is an electrohydraulic proportional relief valve and includes a solenoid configured to adjust the pressure of hydraulic fluid delivered to the implement pump proportionally to a current delivered through the solenoid.

A method for estimating the weight of loads carried by implements may include controlling an implement subject to actual weighing conditions to lift a load and receiving an input indicative of a sensed force associated with lifting the load. The method may further include determining a correlation value indicative of a correlation between first and second force values for lifting a given load with the implement as a function of the actual weighing conditions and as a function of nominal weighing conditions, respectively, where at least one of the actual weighing conditions differs from at least one of the nominal weighing conditions. Furthermore, the method may include determining an adjusted force value for lifting the load based at least in part on the sensed force and the correlation value. Additionally, the method may include estimating the weight of the load based at least in part on the adjusted force value.

A method for estimating load weights for a work vehicle including a boom pivotably coupled to the chassis of the work vehicle at a boom joint and an implement pivotably coupled to the boom at an implement joint may include receiving an input indicative of a tilt force associated with a tilt cylinder configured to pivot the implement about the implement joint, and an input indicative of a lift force associated with a lift cylinder configured to pivot the boom about the boom joint. The method may further include determining a torque about the implement joint caused by the load based on the tilt force and determining a torque about the boom joint caused by the load based on the lift and tilt forces. Additionally, the method may include estimating a weight of the load based on the torques about the boom and implement joints.

Systems and methods for a power machine can provide greater functionality and operator comfort. A climate control system for a power machine can include a condenser, mounted on a front frame member of the power machine. Paths for air flow to cool an engine compartment can extend along airflow passages though a fuel tank. Secondary braking systems can allow a power machine to be stopped with modulated fashion when a primary power source is unavailable. Rear-view vision systems can include a camera mounted on a front pivoting frame (e.g., near the top of an operator station) to provide improved environmental information to an operator. A tilt actuator of the power machine can be configured to operate in a float mode.

A system includes a work vehicle, user interface, and controller. The work vehicle includes a frame, boom, implement, perception sensor, and ground speed sensor. The perception sensor senses an approaching environment. The user interface includes controls and indicators. The controller is coupled to the controls, indicators, perception sensor, and ground speed sensor. The controller receives a command to move the work vehicle, drives the work vehicle, determines a distance to the container, determines the ground speed, determines a boom raising start distance from the container, receives a command to raise the boom, and activates one of the indicators if the user command to raise the boom occurs prior to the work vehicle reaching the boom raising start distance from the container.

A system includes a work vehicle, user interface, and controller. The work vehicle includes a frame, boom, implement, perception sensor, position sensor, and ground speed sensor. The perception sensor senses an approaching environment. The position sensor senses a position of the boom or implement. The user interface includes controls and indicators. The controller is coupled to the controls, indicators, perception sensor, position sensor, and ground speed sensor. The controller receives a command to move the work vehicle, drives the work vehicle, determines a distance to the container, determines the ground speed, determines the position of the boom or the implement, receives a command to raise the boom, raises the boom during travel, determines whether the distal end will reach a threshold height before the work vehicle reaches the container, and activates the indicators if the distal end will not reach the threshold height in time.

Provided is a wheel loader capable of evenly loading a target object for loading onto a target area for loading with simple operation to thus mitigate a burden on an operator. The wheel loader 100 includes a travel device 120 that causes a vehicle body to travel, a drive device 150 that actuates a lift arm and a bucket, an area detection device 160 that detects a loading area, and a control device 170. The control device 170 recognizes the loading area on the basis of a detection result of the area detection device 160 and controls the travel device 120 and the drive device 150, so that the target object for loading contained in the bucket is distributed to be loaded in a plurality of different positions of the loading area while changing the position of the vehicle body in the front-back direction.
