Disclosed is a protective wheel frame of an agricultural working vehicle and a method for mounting a protective frame on a wheel of an agricultural working vehicle. The protective frames, or line openers, are designed to prevent the wheels of working vehicles from damaging crops during their operation. The protective frame includes a segment configured to surround at least a front portion of a wheel of a working vehicle and a connection element. The protective frame may also include additional frame segments that form a structure to support a rigid covering. The method for mounting the protective frame on a working vehicle wheel includes steps for mounting and coupling segments and connecting elements of the protective frame.

A power assembly and a garden tool having the power assembly. The power assembly includes a housing, a driving unit received in the housing and a power supplying unit received in the housing for powering the driving unit. The driving unit includes a driving motor and a control panel assembly located upon the driving motor. The housing has at least one heat dissipation air duct formed therein for airflow passing through the driving unit. The heat dissipation air duct has an air inlet for air intaking and an air outlet for air flowing out, and the air outlet is located at a bottom of the housing and open towards a lateral side of the housing. So that the airflow entering the housing through the air inlet can sequentially flow through the control panel assembly and the driving motor, and finally flows out the housing through the air outlet to take away the heat generated by the driving unit, the working temperature of the driving unit can be reduced and the working efficiency of the power assembly can be improved.

The disclosure relates to a portable work apparatus. The work apparatus includes a spacer which is arranged on the front housing and has a contact region. The contact region has a maximum distance, as measured radially, with respect to the rotational axis of the output shaft, the distance being greater than the cutting radius of the cutting tool in a first, non-deformed state of the spacer. The spacer is elastically deformable. The spacer is elastically deformed in a second state in such a manner that the maximum distance of the contact region is at most the same size as the cutting radius, and the spacer is arranged completely outside the cutting plane of the cutting tool.

An agricultural baler includes: a frame; a feeder system coupled with the frame and including: a cutting assembly coupled with the frame and including: at least one knife configured for cutting a crop material; an overload protection mechanism associated with a single one of the at least one knife and including a pivot device including an engagement device including an offset configuration; and a displacement apparatus configured for selectively forcing the at least one knife to occupy a first position and for selectively forcing the at least one knife to occupy a second position, each by way of the engagement device.

A locking mechanism for a suspension assembly of a harvester, particularly those intended for the harvest of tall and stem plants, such as sugarcane and sweet sorghum, being designed to ensure that the harvester remains raised during maintenance procedures and thus avoids the risk of accidents and damage to the harvester. The locking mechanism includes a lock pivotably mounted to the chassis through a pivoting connection at a pivot end of the lock and disposed adjacent to the actuator cylinder. The lock has an opening configured to at least partially surround a fixed portion of the actuator cylinder and has a circumferential diameter smaller than a diameter of a movable portion of the actuator cylinder. The locking mechanism further includes a locking element disposed at an opposite end of the lock. The locking element is configured to interact with retaining bearings mounted on the chassis.

A lawn mower includes a main body and a power head mounted on the main body. The main body comprises a mounting shell recessed with a mounting groove. The power head comprises a motor assembly received in the mounting groove and a housing assembly covering the motor assembly. The motor assembly comprises a motor base assembled with the mounting shell and a motor fixed on the motor base. The bottom of the motor base is sealed and the side of the motor base is provided with an air outlet and a waterproof rib protruding from the air outlet for partial shielding. The installation bottom surface of the housing assembly corresponding to the air outlet at least partially overlaps the waterproof rib in an up and down direction. Compared with the prior art, the lawn mower has good waterproof performance.

An automated grain filling system including a sensor and a processor. The sensor is configured to detect at least a portion of an upper perimeter of a receiving container and at least a portion of an upper surface of a grain mound in the receiving container. The processor is configured to compare the detected portion of the upper perimeter and the detected portion of the upper surface, and direct the operation of a grain transfer element. The grain transfer element is configured to transfer grain from a supplying container to the receiving container. The directed operation of the grain transfer element is based at least in part on a result of the comparison of the detected portion of the upper perimeter and the detected portion of the upper surface.

A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.
