General Equipment 671 Series Dig-R-Tach®

671/753 Series DIG-R-TACH®

Increase your equipment's versatility and productivity with a 671/753 Series DIG-R-TACH® earth auger attachment. Engineered to perform with skid steer loaders, small excavators, knuckleboom cranes and small backhoes, the smaller Series 16 features a two speed chain/sprocket drive system that allows it to balance smaller flow volumes to auger diameters. Results are cleaner holes with less loose soil and debris.

For higher capacity drilling, the Series 24 is designed for the larger hydraulic systems of backhoes and small excavators. Installation is simple with a dipper-stick mounting bracket.

Low speed hydraulic motors and chain reduction drives deliver smooth, efficient torque transfer to the auger drive shaft while a standard 2 inch hexagon auger drive eliminates connection wear problems. Models with a 2-9/16 inch round drive connection are also available.

A complete line of earth augers up to 36" diameter is available with Pengo® type boring heads. For additional drilling depth, full flighted auger extensions can be added.

General... the worldwide leader in portable hole digging equipment.

Hydraulic System Requirements 5 -20 GPM (19-76 lit/min) flow range. 15GPM (57 lit/min) optimum flow rate. 1500-3000 PSI (105-210 kg.cm2) auxiliary hydraulic system pressure relief valve setting range 15-25 GPM (57-95 lit/min) flow range. 20GPM (76 lit/min) optimum flow rate. 1500-3000 PSI (105-210 kg/cm2) auxiliary hydraulic system pressure relief valve setting range.
Auxiliary hydraulic system flow rate determines auger rotational speed. Auxiliary hydraulic system pressure relief valve setting determines actual digging torque produced. Minimal flow rates and relief valve settings may not produce satisfactory digging performance for specific auger diameters and soil types.

Minimum oil viscosity is 50 SSU with a minimum of .125 percent zinc antiwear additives. Hydraulic system must have sufficient heat rejection capacity to limit maximum oil temperature to 200 °F (93°C) at maximum ambient temperature.

Transmission
Drive System Auxiliary hydraulic system of carrier vehicle serves as power. Low speed, high torque hydraulic motor transfers torque to auger driveshaft though roller chain reduction. Forward and reverse auger direction controlled by auxiliary hydraulic valve foot pedal or hand control. Series 16 incorporates dual sprockets clusters that provide high/low auger speed selection.

Auger
Design Auger construction features Pengo® type, cast-steel boring heads, forged-steel teeth for maximum digging performance and versatility. Think, cross-sectioned helicoid or sectional fighting delivers strength and wear resistance. Fighting pitch is set to produce cleaner, more useable holes in sandy or granular-type soils. All boring head wear parts are field replaceable.
Lead Auger and Auger Extension Length Available in industry standard lengths and diameters. Mounted DIG-R-TACH, auger/extensions and excavated soil can result in substantial weight. Refer to carrier vehicle lift height and operational center of gravity envelope information to determine maximum allowable auger length and weight combinations.
