When it comes to choosing equipment to make top-quality compost, our "manufacturer of choice" for compost windrow turners is Frontier Industrial Corporation, Oregon, USA.. See our list of reference installations. They have a comprehensive range of robust compost windrow-turners:

Frontier F Series Windrow Turners 12' - 22' wide
GreenSqDiamond     Turborator Paddle Drum - U.S.Patent 5,586,731:
This patented technology is the working heart of the Frontier. The drum and paddle design is robust, abrasion-resistant and impervious to rocks and other debris. The Turborater aerates the windrow material as it mixes - left to right - right to left - top to bottom - bottom to top and inside out. Not only does this produce particle-size-reduction without pulverizing, but it creates two CO2 purging circulating airflows, (15 cu.ft. of air for every 1 cu.ft. of material.) The combination of airflow and physical throw of the paddles shape the compost windrow into its optimum shape and porosity. The resulting OXYGENATION and MIXING, yields extreme microbial population growth, producing rapid odor-free composting. 100% mixing/100% aeration + 0% compacting = odor control.


GreenSqDiamond    Self-Trailing - U.S. Patent 5,586,731:
The only compact, self-trailering unit available, you'll spend more time on the job because it is easily moved from site to site. With no special permits required, you'll move from highway to full production in minutes. Self Trailing Compost Windrow Turner

GreenSqDiamond    Clear-View Cab:
Frontier Windrow Turner Another "Frontier first" — only Frontier provides an operator's cab that moves forward to provide a clear view to the front and each side, allowing unsurpassed visibility for accurate driver-control in any situation.

GreenSqDiamond    Four-Wheel Drive: Getting stuck is hard on equipment, frustrating for operators and loses valuable production time. Only Frontier provides positive four-wheel drive at the touch of a button.

GreenSqDiamond    Load Transfer Frame: Frame strength and design integrity that is unequaled in the industry. The main frame's 4" x 12" steel tube is configured like a bridge, transferring loads over the entire structure during self-trailing.

GreenSqDiamond    Odor Control: Odors develop as a result of poorly turned and aerated compost material. Only the Frontier completely turns and aerates all the material in one pass. Why else would you want a turner? For the science behind composting?, click here.
