SRST 110

The SmallRotoSonic Tractor Mast (SRST 110) is a sonic drill rig that can be fitted to a tractor and work off the tractor’s power take-off.

  • Great for rough terrain
  • Small investment, big results
  • True 150 Hz
  • Tractor-mounted drill mast


The SRST 110 sonic drill rig is equipped with a True150Hz SmallRotoSonic 34K drill head. It can drill to a depth of 30-40 metres and is suitable for geotechnical sampling, mining and mineral sampling, environmental research and seismic drilling.  

This special drill rig can be mounted to your own tractor, which makes it a small investment if you want to get started with Sonic drilling. The required horse power for the tractor is 110HP and the SRST110 runs on the PTO. This combination of tractor and drill rig make it possible to work in rough terrain and easily move the rig from one job site to another.  

The SRST 110 has been proven effective in several different environments, including farmland and mining areas with many logistical movements and the requirement for 4x4 terrain capability.  

The drill head is equipped with 2 mechanically synchronised eccentrics providing 150 kN output force. The rig itself comes with a load sense hydraulic system, work lights, and a 150 litre water tank.   

Optional features include:  

  • Casing rack  
  • ManipAll 200 rod and casing handler  
  • Swivel for water-assisted drilling 
  • Double hydraulic break-out clamp
