Skid steer loader
Fast positioning for repetitive holes
Telehandler
Reach and stability on open sites
Typical applications
Configured around the hole your project needs.
Auger diameter, ground tool and extension length can be selected according to soil condition, drilling depth and application requirements.
Fencing & posts
Holes for fence posts, signs, gates and boundary structures.
Tree planting
Ground preparation for landscaping, orchards and nurseries.
Light foundations
Drilling for selected footings and site structures.
Agriculture

Selection FAQ
Information needed before recommending a model.
Complete machine and application details help reduce compatibility risk and improve quotation accuracy.
Which carrier information should I provide?
Please provide the machine brand, model, operating weight, auxiliary hydraulic pressure, oil flow and the mounting interface or quick hitch currently used.
How do I choose the correct auger diameter?
Selection depends on hole diameter, depth, ground condition and available torque. Larger diameters and harder ground generally require a higher-torque drive.
Can the drive be used on different carrier types?
The REA range can be configured for excavators, skid steer loaders and telehandlers. Each installation requires a suitable mounting solution and verified hydraulic compatibility.
Are extension shafts available?
Extension options can be selected to increase drilling depth within the working limits of the complete drive, auger and carrier configuration.
Can brackets and product identification be customized?
Mounting arrangements and selected product identification details can be discussed during quotation. Confirm the required scope with the RAY sales team.
