This is Eterra's classic flail mower, the best-selling EX-30! Featuring 20 2.25 lb Y-Knife flail blades powered by a Permco gear drive motor, this little beast can easily cut through grass, brush, and small trees! With a 500-hour blade life, strong construction, and a 1-year Eterra warranty, this mower will be serving you for a long time!

Eterra has conducted extensive research and development to find the right materials to make this mower lighter than other mowers in its class to keep it cutting in all conditions, including side hills and uneven terrain, without it becoming unstable. Eterra is able to use top-quality steel in these mowers while keeping them lightweight at the same time. The welding and machining are second to none.

Eterra uses premium Permco USA motors and a 2 lb blade. The cutter shaft is electronically balanced for the most efficient operation and longest operating life in its class.

A blank universal mounting plate is included with the EX-30. Each customer is responsible for mounting the coupler necessary for their excavator. This implementation requires a case drain line due to the high speeds and pressures involved. 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. Some newer machines like Yanmar have a return-to-tank setting, which eliminates the need to drain the case.

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. Metallurgically, 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 auxiliary 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.
