In accordance with one aspect of the present disclose, a lift apparatus for a work machine is provided. The lift apparatus may have a horizontally disposed lift frame that has a mount on its top surface. The lift apparatus may further include a first elongated member having a first end and a second end. The first elongated member is vertically disposed and attached to a first side of the lift frame at the first end, and the second end includes a first attachment point for attaching to the work machine. The lift apparatus further includes a second elongated member that has a first end and a second end, the second elongated member is vertically disposed and attached to a second side of the lift frame at the first end, and the second end includes a second attachment point for attaching to the work machine.

A device for the deaeration of a hydraulic fluid of a hydraulic system has at least one hydraulic motor arrangement and a hydraulic fluid storage which is hydraulically coupled with this hydraulic motor arrangement. A suction device for sucking out the hydraulic fluid is associated with the at least one hydraulic motor arrangement such that the suction device guides hydraulic fluid out of the hydraulic motor arrangement into the hydraulic fluid storage by means of vacuum pressure (Δp). The suction device is constructed as a jet pump and is integrated in the return line between the hydraulic motor arrangement and hydraulic fluid storage.

A work vehicle includes a vehicle body, a work implement including an attachment, an operating device and a controller. The operating device can be operated to a dump side and a tilt side to cause the attachment to dump and tilt. The controller executes an automatic drive control in which the attachment is caused to dump as far as a predetermined dumping position when the operating device is operated by a first dump operation amount or greater to the dump side, or to tilt as far as a predetermined tilt position when the operating device is operated by a first tilt operation amount or greater to the tilt side. The controller disables the automatic drive control when a switching time period required for the operating device to be switched between the tilt and dump sides is at least a predetermined disabling time period.

An electric loader is provided with a plurality of independently driven wheels. For example, a four-wheeled electric loader includes four independently operated wheels, each directly coupled to a dedicated electric motor. A fifth independent electrical motor powers the lift arm and/or any attachments coupled to an auxiliary hydraulic. A central forced-air system supplies pressurized air to each independent electric motor to cool the electric motor during operation. In some embodiments, the auxiliary electric motor powers the fan and/or air conditioner of the central forced-air system. A lever and/or electric brake may be applied to an axle of the electric motors. In some embodiments, a rotating or pivotable battery panel locks a plurality of battery cells to provide a central source of power, counter-weight the loader arm, and rotate away to provide the operator access to an internal cavity of the cab.

A method for depositing material at a target location with a work vehicle includes receiving an input associated with a target weight of the material to be deposited at the target location. Additionally, the method includes controlling an operation of the vehicle such that an implement of the vehicle obtains a quantity of the material. Furthermore, the method includes controlling the operation of the vehicle such that the implement is raised from a first to a second position. Moreover, the method includes determining a weight of the currently obtained quantity of the material as the implement is raised from the first to the second position. In addition, the method includes controlling the operation of the vehicle such that the currently obtained quantity of the material is deposited at the target location. Further, the method includes initiating display of a current total weight of the material deposited at the target location.

A multiple mode operational system for a work machine may comprise a frame, a ground-engaging mechanism coupled to the frame, an attachment, an object detector, and a multiple mode control system. The multiple mode control system may include a control device and a controller receiving a signal from the control device. The controller may have a first operational mode and a second operational mode. The first operational mode may enable a first sensitivity response to the control device and the second operational mode may enable a second sensitivity response to the control device. The controller may be configured to receive an object signal from the object detector and modify the operational mode of the controller based on a detected distance of the object from a reference point.

Provided is a work machine capable of notifying that maintenance is necessary due to continuation of clogging in a cooling device or decrease in cooling performance. A wheel loader 1 including a radiator 31 and an oil cooler 32 comprises a controller 5, 5A configured to determine a clogging continuation state of the radiator 31 or the oil cooler 32. The controller 5, 5A determines whether clogging is occurring in the radiator 31 or the oil cooler 32 based on outside air temperature AW and cooling water temperature CW or hydraulic oil temperature HW, determines whether the clogging continues based on a clogging occurrence ratio R1, R2 while an engine 30 is operating, and outputs a notification command signal for providing the alarm buzzer 61 and the user management system 62 with a command to notify that maintenance is necessary when it is determined that the clogging continues.

A hydraulic system for controlling an implement on a work machine may include a hydraulic reservoir, a hydraulic pump in fluid communication with the reservoir, a central valve in fluid communication with the pump and configured for controlling the implement, a load sense pressure relief system, and a controller. The controller may be configured for controlling the central valve and the load sense pressure relief system and selecting between operating the hydraulic system at a first pressure and a second pressure based on a factor relating to implement position.

A working machine has a frame, a ground engaging propulsion system, a drive arrangement for providing motive power to the ground engaging propulsion system, an operator platform pivotally connected to the frame and moveable between a deployed position for supporting an operator thereon and a stowed position; and a sensor arrangement configured to sense when an external force is applied to the operator platform when said operator platform is in the deployed position. The machine prevents movement of the ground engaging propulsion system when the sensor arrangement does not sense an external force applied to the operator platform when said operator platform is in the deployed positon.
