Removable cab toe boxes are described herein to provide increased comfort to an operator while still allowing a cab to be rotated upwards to provide access to equipment below the cab. The removable toe boxes are removably affixed to the cab and, when installed, may provide at least a partial seal to prevent or reduce the amount of dirt or dust entering the cab. When the toe boxes are removed, equipment may move through the space created from the removal of the toe boxes to allow the cab to rotate.

Removable cab toe box for a work machine

A manual input device for a machine includes an elongate handle rigidly connected at one end to a frame of a machine and configured to be engaged by a hand of an operator, and a control portion connected to a free end of the elongate handle. The control portion includes a first plurality of control surfaces and a second plurality of control surfaces associated with sensors providing control signals. The first plurality of control surfaces is positioned and oriented relative to the handle portion so it is accessible for interaction by a thumb of the hand of the operator, and the second plurality of control surfaces is positioned and oriented relative to the handle portion so it is accessible for interaction by an index finger of the hand of the operator.

Manual input device and method

A grading control system may have a lift actuator to raise or lower a work implement, and a tilt actuator to tilt the work implement. The grading control system may also have a first sensor that communicates a signal indicative of a position of the work implement, and a second sensor that communicates a signal indicative of a position of the machine frame. The grading control system may have a controller to determine a track plane of the machine and a desired grade relative to the track plane. Further, the controller may determine an orientation of the work implement relative to the track plane to maintain the desired grade based on the sensor signals. The controller may also be configured to actuate one or both of the lift and the tilt actuators to orient the work implement according to the determined orientation.

An attachment assembly configured to be removably coupled between a first jaw and a second jaw of a clamping bucket. The attachment assembly includes a pair of sidewalls spaced from each other in a first direction and at least two structural beams spaced from each other in a second direction. Each of the first sidewall and the second sidewall includes a first connection interface configured to be removably coupled between the front jaw and the rear jaw, a retention arm configured to interconnect to a back surface of the rear jaw, and a second connection interface configured to interface with a working tool. The attachment assembly can also include a reaction arm configured to be arranged adjacent a bottom surface of the front jaw of the clamping bucket.

A tank for a hydraulic fluid has a housing with opposed end walls and side walls defining an interior chamber. A primary baffle is disposed inside the housing and divides the interior chamber into an inlet chamber and an outlet chamber, with a primary gap between the primary baffle and the housing fluidly communicating between the inlet chamber and the outlet chamber. The primary baffle further defines a contact surface facing the inlet chamber and has first and second weirs which extend into the inlet chamber. A first fluid inlet fluidly communicates with the inlet chamber and is oriented along a first inlet axis that intersects the contact surface, while a fluid outlet communicates with the outlet chamber. The tank produces an interior flow that mixes and deaerates the fluid as it travels from the first fluid inlet to the fluid outlet.

A machine throttle system according to an embodiment of the present disclosure includes a power system configured to operate at different speeds. The power system is coupled to a first throttle device and a second throttle device. A control module is communicatively coupled to the power system, the first throttle device, and the second throttle device. The control module is configured to cause the power system to operate at a first speed in response to the first throttle device being set to a level. The control module is also configured to cause the power system to increase in speed in response to the second throttle device when the first throttle device level is set below a predetermined value. The control module is further configured to cause the power system to decrease in speed in response to the second throttle device when the first throttle device level is set at or above the predetermined value.

A machine includes an internal combustion engine disposed within an engine compartment and supported on a machine frame. An exhaust stack has an inlet fluidly connected to an exhaust manifold of the internal combustion engine and an outlet in fluid communication with ambient air. A diesel particulate filter is disposed along the exhaust stack. A cooling package includes at least one heat exchanger and a blower fan. The blower fan is configured to blow cooling air from the engine compartment sequentially through the at least one heat exchanger and an outlet of the cooling package. Exhaust gas exiting the exhaust stack outlet is mixed with the cooling air exiting the cooling package outlet in a high temperature zone surrounding the exhaust stack outlet to form a fluid mixture, and a temperature of the fluid mixture at a perimeter of the high temperature zone is below 200 degrees Celsius.

A skid steer machine includes an operator cage supported on a skid steer machine frame, a pair of lift arms pivotably attached to the skid steer machine frame behind the operator cage and extending longitudinally on both sides of the operator cage, and a rear mounted engine compartment supported on the skid steer machine frame. The rear mounted engine compartment includes an internal combustion engine, a diesel particulate filter fluidly connected to the internal combustion engine and positioned between the internal combustion engine and the operator cage, and a cooling package having a predominantly horizontal orientation. The cooling package is at a higher location within the rear mounted engine compartment than the diesel particulate filter.

A machine includes an internal combustion engine disposed within an engine compartment and supported on a machine frame. An exhaust stack has an inlet fluidly connected to an exhaust manifold of the internal combustion engine and an outlet in fluid communication with ambient air. A diesel particulate filter is disposed along the exhaust stack, and the machine includes an active regeneration system for regenerating the diesel particulate filter. A cooling package including at least one heat exchanger and a blower fan. The blower fan is configured to blow cooling air from the engine compartment sequentially through the at least one heat exchanger and an outlet of the cooling package. Exhaust gas exiting the exhaust stack outlet is mixed with the cooling air exiting the cooling package outlet in a high temperature zone surrounding the exhaust stack outlet to form a fluid mixture. An electronic control module is in control communication with the active regeneration system and includes a regeneration control algorithm operable to detect a speed of the blower fan.
