An earth levelling blade assembly for mounting on the lift arms of a loader includes a laterally extending main blade and two shoes supported at opposing ends of the main blade for sliding engagement along the ground. The shoes are supported for movement between a forward position ahead of the main blade and a rearward position behind the main blade, as well as being adjustable in height relative to a bottom cutting edge of the main blade. A coupling arrangement between a first mounting frame on the lift arms of the loader and a second mounting frame on the rear mounting face of the main blade (i) supports the second mounting frame to be freely pivotal about a forward axis relative to the first mounting frame in which the forward axis is oriented in the forward working direction of the loader and (ii) supports the second mounting frame to freely translate relative to the first mounting frame along an upright axis.

A transmission system for a machine is coupled to an engine of the machine that is adapted to generate power. The transmission system includes a hydraulic power path including a variator coupled to the engine. The transmission system also includes a mechanical power path. The mechanical power path includes a first gear arrangement including a plurality of gears. The mechanical power path also includes a second gear arrangement including a plurality of gears. The second gear arrangement is coupled with the first gear arrangement to receive the variable rotational power from the first gear arrangement. The mechanical power path further includes a first clutch assembly and a second clutch assembly. Further, the second gear arrangement directs the variable rotational power received from the first gear arrangement towards a final output member of the machine in a selected direction.

A mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

Systems and methods for implementing a machine control system within a construction machine. The machine control system may include a chassis orientation sensor configured to be mounted to a chassis of the construction machine for detecting a chassis pitch angle. The machine control system may also include an implement orientation sensor configured to be mounted to an implement of the construction machine for detecting an implement pitch angle. The machine control system may further include one or more processors configured to perform operations including receiving, from the chassis orientation sensor, the chassis pitch angle, receiving, from the implement orientation sensor, the implement pitch angle, determining a target pitch angle of the implement based on the chassis pitch angle and the implement pitch angle, and causing movement of one or more implement arms so as to set a pitch angle of the implement to the target pitch angle.

A method of calibrating a grade control system is provided. The method includes placing a smartphone on first defined calibration location of a work machine. The smartphone determines a slope of the first defined calibration location relative to gravity. The smartphone is placed on a second defined calibration location of the work machine and determines a slope of the second defined calibration location relative to gravity. The slope of the first and second defined calibration locations is automatically communicated to the grade control system and is employed for subsequent grade control.
