Eterra EX-50 Heavy Duty Excavator Brush Mower

The Eterra EX-50 Brush Mower for mini or small excavators is ideal for clearing brush from roadsides, driveways, ditches, and much more. 

Designed for backhoes and excavators from 17000 lbs. to 25,000 lbs. The EX-50 operates efficiently on hydraulic flows from 15 - 50 GPM.

With cutting capacities up to 6 inch material, this mower ROCKS! At 778 lbs. without a mount, the EX-50 is strong enough for the toughest projects. A lot of effort has gone into using the right materials to make this mower lighter than other mowers in it's class to reduce your swing weight and keep you cutting in all conditions. Not just level and flat. With this lower weight, you can easily work side hills and not fear your going to tip your machine. But don't worry, Eterra still uses top quality materials and the finest design to insure you have a mower that will last and last. Skid Steer Solutions backs this product up with our no hassle, 1 year warranty.

  • If you want to build your own coupler, please select "Other Coupler" and we will contact you (price and warranty may vary)

All Eterra drive systems have been proven to be strong and reliable. Eterra uses a 2.25 lb. blade and premium Permco USA motors. The welding and machining is exceptional. Fit and function, OUTSTANDING! Many of these have been sold in the USA, Canada and Australia. Eterra would be happy to supply you with references upon request to Skid Steer Solutions.  Eterra customers are the company's best salesmen.

With the compact flail design, you will be able to access the smallest of properties and mow small brush, berry bushes and grass into a fine mulch which leaves you with virtually no clean-up.

The EX-50 is built from lightweight and strong materials. The cutter shaft is electronically balanced for the most efficient operation and longest operating life in it's class. If you are looking for the best in show, then Eterra mowers have it hands down.

Please note that the EX-50 comes with a blank universal mounting plate. The customer is responsible for mounting the specific coupler required for your excavator. Due to the high speed and pressures involved, a case drain line is required to operate this implement. A case drain is a low pressure line that travels from the mower head back to your oil reservoir. It allows pressure to be directed away from the motor seals and back to your oil tank. This increases your seal and motor life substantially. Check with your dealer as some newer machines including Yanmar have a return to tank setting which makes a case drain unnecessary.

The Eterra Cutter Shaft

Eterra uses 6" DOM Tubing for their cutter shafts to insure a strong and long wearing product. Ettera does not use steel pipe. Eterra cuts it themselves and constructs one of the toughest shafts available. Then it is electronically balanced so when the flail is operating, it is hard to tell. No shaking from side to side or up and down. This is just another step that Eterra adds to make their mowers much better than the competition. Eterra's goal is to produce the best possible product and deliver it to you in the most economical manner.

Drawn Over Mandrel (DOM)

Strong and well-finished DOM is an electric resistance welded tube tested for soundness of weld and drawn through a die and over a mandrel. This process imparts significantly improved mechanical properties to the tube, due to the cold working process. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel. Note that, technically DOM refers to the process by which the tube is finished after having started as an ERW tube. Technically, DOM is not a type of steel tube, but rather a process. As so often happen though - in common use the term has become accepted to mean a specific type of tubing rather than a process. In this case, when people say "DOM" they normally mean an ERW tube drawn over a mandrel at (close to) room temperature and made from SAE 1020 steel. It is normally drawn to O.D. and I.D. dimensions. Here is what the Steel Tube Institute of North America has to say about DOM:

"The manufacturing process for DOM tubing begins with coils of steel, which are slit to the proper width for the desired tube size. The strip is cold formed and passed through an electric resistance welder which joins the edges together, under pressure, to complete the tubular shape. After testing the weld's integrity, the tubing is cut to length for further processing.

The cold-drawing process creates a uniform, precision product with substantially improved tolerances, surface finish and tensile strength, increased hardness and good machinability. In this process, the tube is cleaned and annealed, and one end of each length is squeezed to a point so it can be gripped by the drawing mechanism. The tube is then drawn through one or more dies and over mandrels. This reduces the diameter of the tube and thins its walls to the required dimensions in a controlled fashion to provide the qualities desired in the finished product. Metallurgic-ally, drawing improves the tube's concentric, tensile strength, hardness and machinability. Close dimensional accuracy is achieved through tight control of both outside and inside diameters."

Note:  Every excavator is different.  Many machines (Especially older models) use only two pumps.  One to control your stick and rotation.  One for track drive and auxilliary flow (your mower).  For machines that have this type of pump arrangement, it is not possible to drive the machine forward and cut at the same time.  You will need to drive forward, stop and then sweep back and forth for cutting.  For operators with newer machines like Kubota and any Yanmar, you have three pumps so you can drive and cut at the same time.
