DESCRIPTION

Cat® Augers are used to drill holes for footings, fencing, sign posts, trees and shrubs in construction, agricultural and landscaping applications.Cat® Augers are used for drilling holes for footings, fencing, signs, trees and shrubs in construction, agricultural, and landscaping applications. They are designed with the right amount of speed and torque for maximum productivity in a broad range of soil types.

Application

Cat® Augers are used to drill holes for footings, fencing, sign posts, trees and shrubs in construction, agricultural and landscaping applications.

Multiple Drive Systems

Three different drive systems, all designed with the right amount of speed and torque for working in a broad range of soil types.

  • A23 feature a variable speed, bi-directional, gerotor style hydraulic motor that generates optimal bit speed and output torque for light to moderate duty work.
  • A41 features a variable speed, bi-directional, single reduction planetary drive gerotor style hydraulic motor mounted to a planetary gear box for optimal bit speed and output torque for moderate to heavy-duty applications.
  • A68 features variable speed, bi-directional, double reduction planetary drive hydraulic gear motor mounted to a planetary gear box for optimal bit speed and output torque for moderate to heavy-duty, high performance drilling requirements.

Rugged Bits for Every Application

Rugged bits are adaptable to a number of projects. Standard bits, tree bits, industrial bits and standard rock drill head bits (bolt-on) are offered to cover a wide variety of applications and ground conditions.

Bit Extensions and Adapters

Various extensions allow for digging deeper and adapting to round or hex shaft bit designs. Retention pin reduces time to auger flight changes.

Articulated Joint

Articulated joint ensures auger hangs straight, independent of machine positioning.

Mechanical Swing Stops

Mechanical swing stops protect from auger over swing.
