With cutting capacities up to 6+ inch material, this mower can take anything you throw at it. Click Here for Skid Steer Boom Mounted Version.

With the lower weight and tough construction, you can easily work side hills and not fear that you might tip your machine over. Eterra uses top quality materials and innovative design to ensure you have a mower that will handle difficult jobs today, and last for years to come. Skid Steer Solutions, Inc. backs this up with with a no hassle, 1 year warranty that leads the industry.

All excavator mounted Cyclone 48" Mowers come equipped with 1/2" Flat Face Couplers.

Key Features and Benefits

All drive systems used in Eterra mowing and clearing products have been proven strong and reliable. They use premium Permco USA motors and a 9 lb. blade which is one of the heaviest in its class. The 1" thick T1 grain controlled steel blade bar design allows for heavy and continuous use, dynamic balancing, and moderate mulching capability.

Most of the competitors models use a brush hog style blade which is just a small grass cutting knife. It is not a chopping blade meant for heavy material.

Eterra's welding and machining is exceptional. The blade bar and blades are electronically balanced for the most efficient operation and longest operating life in its class. This is a product designed to put the pride back into "Made in America". 

The Eterra Cutter System 

Eterra mowers use a direct drive spindle hub which is the same hub used on the Typhoon Skid Steer Clearing Mower. Eterra does this to insure maximum impact strength when clearing heavy material. Operator safety comes first to Eterra and a reliable drive system that will never come apart is a priority. Eterra takes the safety of their mowers to another level by insisting all of the steel, machining, and drive systems are USA manufactured.


The Cyclone uses removable gates on the front and rear of the cutter so you can remove them for heavy brush clearing when you need to but still easily install them when you are in areas that you want to minimize the amount of material being ejected from the cutter. Eterra is the only manufacturer on the market that does this.

Testimonial From the Owner of Eterra Attachments

"Why are Eterra Mowers more expensive than some? You will see some mowers are less expensive than these and what you will get is a simple box with no design at all. This box has a small drive system with brush hog style blades installed. Many of these drive systems consist of a 90 degree gear box originating in China or India. This is done so the manufacturer can use a smaller motor and step up the power. This is definitely not what we are selling here. Their's are toys while Eterra products are machines built to do serious work."
