An improved vacuum device for use with a vacuum assisted post hole digger tool. The improved vacuum device includes two suction providing motors with their suction outlets connected in a parallel fashion directly to a filter box. The dual motor configuration provides significantly improved suction power over existing vacuum devices but is still able to be powered on household 120V AC power. The improved vacuum device is paired with a post hole digger apparatus which includes an elongated hollow tubular tool for transmitting vacuum to the base end of the tube. The base end of the tube further comprises a variety bore heads for breaking up soil. A variety of devices for breaking up soil or removing clogs around the bore head are included: a thrasher bar, a hammer bar and an unclogger bar. Each of these devices are designed to be activated either manually by the user by application of force at the upper end of the tool or by application of rotary force by a motor disposed at the top of the housing.

Skid-steer loader attachment assemblies configured to perform earth augering are provided. The attachment assemblies can include a pair of outriggers. Methods for performing earth augering using a skid-steer are also provided. The methods can include extending dual outriggers from a boom assembly of a skid-steer to engage substrate; and extending an earth auger into the substrate from an auger assembly that is operably engaged between the dual outriggers. Skid-steer loader and attachment assemblies configured to perform earth augering are also provided. Boring assembly coupling assemblies are also provided.

A post hole digger couples to the power take-off (PTO) shaft of a tractor and uses rotation from the PTO shaft to rotate an auger. A top support arm rotatably coupled to the top pin of the tractor's three point hitch supports the gearbox that translates rotation to the auger. A support frame extends upwardly from the right and left lift arms of the three point hitch and inwardly to support the top support arm from beneath. The support frame is shaped generally as an inverted “U,” with space created between the right and left lift arms to prevent interference with the rotating shaft that translates rotation from the PTO shaft to the gearbox. A shield coupled to the gearbox covers the moving parts of the joint between the rotating shaft and the gearbox and protects users during use of the auger.

A drill system, a machine, and a method of operating the same, are disclosed. In one aspect, a machine includes a machine frame coupled to at least one ground engaging element, a power source configured to generate a power output for driving the at least one ground engaging element, and a cabin structure coupled to the machine frame and having an overhead portion configured to provide overhead protection to an operator. The machine further including a boom coupled to the overhead portion of the cabin structure and a drill assembly moveably coupled to the boom.

A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The utility chassis has a lightweight vertical frame member with an overall center of gravity that allows for manual lift handles to be arrayed about the center of gravity for easy loading and unloading onto transportation vehicles without the need for separate heavy machinery. The utility chassis incorporates a spring-centered closed position valve for drill rotation and a three-way spring-centered retract with two open feed positions valve for increased safety. A hinged drill rod guide cap is incorporated into the drill rod guide for quick removal of the chassis from lodged or broken drill rods. The chassis is lighter, more ergonomic, and safer than prior art chasses.

An improved vacuum device for use with a vacuum assisted post hole digger tool. The improved vacuum device includes two suction providing motors with their suction outlets connected in a parallel fashion directly to a filter box. The dual motor configuration provides significantly improved suction power over existing vacuum devices but is still able to be powered on household 120V AC power. The improved vacuum device is paired with a post hole digger apparatus which includes an elongated hollow tubular tool for transmitting vacuum to the base end of the tube. The base end of the tube further comprises a variety bore heads for breaking up soil. A variety of devices for breaking up soil or removing clogs around the bore head are included: a thrasher bar, a hammer bar and an unclogger bar. Each of these devices are designed to be activated either manually by the user by application of force at the upper end of the tool or by application of rotary force by a motor disposed at the top of the housing.

A quick disconnect Kelly bar system is provided. In use, a construction attachment includes a quick disconnect mounting plate for connecting the construction attachment to a hitch of a construction machine. A pivotable coupling assembly is connected to the quick disconnect mounting plate. Additionally, an extendable mast is connected to the pivotable coupling assembly at a first end of the extendable mast, and to a headblock structure at a second end of the extendable mast. Further, a Kelly-bar assembly is connected to the headblock structure.

The disclosure provides a gear assembly, a transmission mechanism and an electric drill. The transmission mechanism includes a sun gear, a planetary gear assembly and an output shaft. The sun gear is arranged on a motor output shaft of a driving motor. The planetary gear assembly includes a planet carrier and a planetary gear. The planetary gear is arranged on one side of the planet carrier and meshing with the sun gear. A shaft hole is arranged on a gear in the planetary gear. A gear shaft is mounted in the shaft hole.
