General Equipmentâ„¢s 300 Series Hole Diggers

General Equipmentâ„¢s 300 Series professional hole diggers provide the performance and power needed to handle heavy-duty digging projects, from commercial fencing to upscale landscaping. 


A four-cycle, 3,600-rpm Honda GXV140 5-horsepower gasoline engine powers the series, and a Lo Tone muffler reduces operating sound. A resistor-type spark plug helps with starting. To increase operator control, a rugged and durable Magura twist-grip throttle is positioned to maximize hand and arm strength. The heavy-duty, spring-return throttle provides precise control within the operatorâ„¢s hand.


Multiple driveshaft options make the 300 Series adaptable to competitive augers so that existing inventories can easily be accommodated. The 330H auger features a 1-3/8-inch hexagon General® driveshaft auger connection. The 343H uses a 7/8-inch square Ground Hog®-type connection, and a Stihl®-type connection is used on the 357H. Numerous auger size options also are available, with diameters between 2 and 18 inches. Adding full-length, flighted auger extensions can increase the standard 3-foot drilling depth, as well.


Generalâ„¢s exclusive, patented transmission design features a totally enclosed oil-lubricated spur gear reduction. The precision machine-cut spur gears deliver unequaled torque and horsepower to the auger, pushing the unit to a maximum 190 foot-pounds. The all-metal centrifugal clutches are oil-cooled to extend service life and have been designed to slip should the machineâ„¢s capabilities become overloaded. This ability to partially disengage will prevent damage to the auger and maximize operator safety during an overload situation or upon sudden contact with buried obstructions.


General™s Pengo®-type, cast-steel boring head configuration provides the most aggressive design available for use in difficult soil conditions. Cast-steel screw bits and forged-steel teeth contribute to the auger™s versatility in a wide cross-section of soil compositions. Additionally, each auger™s flighting pitch is set to drill cleaner holes in granular soils, producing more usable holes.


Designed with operator comfort in mind, each 300 Series hole digger features ergonomically positioned Comfort-Flex handles that absorb vibration while enhancing operator control and minimizing fatigue. Additionally, the high-strength composite Comfort-Flex material helps to insulate the operator should the auger come into contact with underground power sources. An ultraviolet inhibitor built into the material minimizes sunlightâ„¢s damaging effects.


Built for long service life under heavy-duty use on construction sites, the 300 Series offers durable parts that require minimal maintenance. Thick, cross-sectioned helicoids or sectional auger flighting delivers maximum strength and wear resistance. The high capacity Timken® bearings require little maintenance, and all wear parts on the auger head are field replaceable.
