A vacuum-assisted hole digger includes a central vacuum tube extending at an upper end from a handle assembly to a digger head assembly attached at a lower end, the digger head including a scraper blade assembly within a housing formed of an orifice plate and saw blade. The orifice plate attaches to the central vacuum tube, an extraction aperture formed in the orifice plate opening into the tube. Air entry apertures formed in the orifice plate outside of the vacuum tube have a total area smaller than the area of the evacuation aperture, which obtains enhanced airflow rates through the digger housing upon connection of the upper vacuum tube opening with a vacuum source. The blade edges of the scraper blade assembly abrasively engage the soil face when digging in a manner that obtains reduction in soil particle size and enhances soil particle airflow entrainment.

A handheld trenching apparatus and method of forming a trench in ground using the apparatus. The apparatus has a frame, a cutting head, and a drive. The cutting head has a ground penetrating portion with a plurality of cutting members that are caused to be moved in a controlled path by the drive. The frame has an elongate frame part with the cutting head at one frame part end. The frame further has at least one graspable region spaced lengthwise of the elongate frame part from the first elongate frame part end. The ground penetrating portion is directed into the ground and while engaging the at least one graspable region the ground penetrating portion is moved in a trench forming direction as the drive is operated to thereby form a trench.

An electrical handheld shovel system includes a handheld shovel with an auger bit. The shovel includes a motor configured to rotate the auger bit and a portable power source configured to power the motor. The shovel includes an input/output (I/O) device and a controller to control rotation of the auger bit. The shovel has a handle and a shovel portion. In one example, the power source is integrated into the handle, and in another example, the power source is detachably coupled to the handle. The shovel has a gearbox coupled to the motor. The shovel portion includes a blade positioned proximal to the auger bit to retain debris from the auger bit. The auger bit has a flute that is partially covered by the blade, and the blade defines a discharge opening configured to discharge at least some of the debris.

A wheel loader includes a console box, a link rod, and a shutoff valve. The console box is disposed on the side of an operator's seat, is able to rotate in the forward and backward direction between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position, and has a slot. The link rod is connected at one end to the slot and transmits the rotation of the console box. The link rod is able to rotate a shaft to switch between an open position in which an actuator drive-use hydraulic circuit can be actuated, and a closed position in which the actuator drive-use hydraulic circuit cannot be actuated. A second end of the link rod is linked to the shaft.

An adjustable guided rake apparatus and method, which enable an adjustable guided rake user to configure an adjustable rake guide to a specified height in relation to a secondary surface, which will then define the height of the grading edge of the grading rake head in relation to a primary surface. The adjustable guided rake user is able to move the grading rake head along a primary surface, in order to shift material along the surface, while the adjustable rake guide runs along the secondary surface, guiding the grading rake head.

A digging implement including: a digging head (16); a substantially elongated main shaft (12) extending from the digging head (16); a main handle (14) secured to the main shaft (12) substantially opposed to the digging head (16); and an auxiliary handle assembly (140) and a footplate assembly (160) both mounted to the main shaft (12) between the digging head (16) and the main handle (14), the auxiliary handle assembly (140) and foot plate assembly (160) being each mountable to the main shaft (12) at different longitudinally spaced apart positions therealong.

A trenching tool including an elongated pole having a bottom end connected to an elbow construction. A hollow cylindrical tube is movably mounted to the bottom end of the elbow construction. The tube is opened on both ends allowing loading of and emptying material scooped from the trench. An adjustable connection secures the tube to the elbow construction.
