Terra Xtreme


The Terra XTREME is a cutting edge mobile soil pulverizer, featuring a continually refined and updated design, yet is simple to use and easy to maintain.  Our pulverizers are the result of decades of field use, and results driven engineering alterations. We take pride in our ability to customize each of our machines to best fit an individual customer’s needs. Each is hand built in our manufacturing facility in Oklahoma City. A Terra XTREME can help to reduce the amount of equipment on your yard. It is a flexible workhorse that can be operated by one man and can be loaded and transported with relatively basic supporting machinery. The machines are easy to maneuver around a worksite. All models are road legal, include high visibility badging, and are as stable to tow as a large mobile home or boat. Our machines are designed to be simple to use and maintain. All controls are visible and labeled. One person trained in the operations can run and monitor the machine, as well as load the material. Maintenance is also designed to be very simple, and as easy as possible. The number of moving parts has been designed down to a working minimum, with friction leading to most wear and tear of an acceptably maintained machine. Monitoring gear lubricant, engine condition, tire tread, conveyor condition, upper knives, hammers & hammer-rods, and hammer-mill disks are the primary maintenance needs. The Terra XTREME is available with the following power packages: Tier III Diesel engine, Tier 4 Final Diesel engine, and Electric motors. The Terra XTREME is available for international sales.
