Designed for a combination of conditions, Eterra Attachment’s Excavator Brush Mower can quickly adjust to sudden changes in terrain, material types, and directions. Being a flail style mover, it will clear brush from roadsides, ditches, driveways, fields — its uses are limited only by a lack of creativity. The EX-30 fits backhoes and excavators from 7,500 lbs to 14,00 lbs; the EX-40 from 9,000 lbs to 20,000 lbs; and the EX-50 from 17,000 lbs to 25,000 lbs.


With cutting capacities ranging from 4-inch to 8-inch material (depending on the attachment size) and a swing weight light enough to cut in all directions and inclines without the fear of tipping, this attachment must house only the most efficient systems. Superior balanced shaft and 2 lb blades powered by a quality Permco USA motor, Eterra upholds its commitment to using systems that have proven to be strong and reliable. 


In terms of the finer details, the cutter shaft uses a 5” DOM tubing instead of a steel pipe. This allows the shaft to be custom cut then electronically balanced to prevent shakiness during operation. Please note that DOM is a process rather than a type of steel tube: the tubing is “drawn over mandrel” and is an electric resistance welded tube tested for soundness of weld and drawn through a die and over a mandrel. By doing this, the mechanical properties of the the tubing are significantly improved from the cold working process using SAE 1020 or 1026 steel. This cold drawing process creates a uniform and precise product with improved tolerances, surface finish and tensile strength. This attachment is exceptional precisely because it is the perfect combination of the right materials and industry expertise.


“Everyone in the industry uses a schedule 80 pipe, which has an increased likelihood to bend and break. At Eterra, we use a 75,000 psi with DOM, which can take more abuse, 

is more accurate, and has no vibrations. We have engineered a proprietary machine — used exclusively by us in the industry — that electronically balances the cutter shaft. With 13 years of experience at other companies, I understand how the competitors’ machines run. This knowledge has allowed me to design machines that are structurally stronger and can withstand real life scenarios. We understand the importance of durability, as these are the machines that operators rely on day-in and day-out to put food on the table for their families.” — Cody Corfe, Product Engineer. 


All of the Excavator Brush Mowers come with a blank universal mounting plate. Because this attachment requires a case drain line that directs pressure away from the motor seals to the oil tank, it is important for the operator to select the right coupler for their excavator. However, case drains are not required for Bobcat, John Deere, Yanmar, Kubota, Caterpillar or Case Excavators.
