We built our first turner over two decades ago to turn the unturnable - Grass seed straw. This long, clumpy and stringy, lightweight material could not be thrown clear of the old-fashioned designs of flails, knives or paddles. These devices would grab the material, wind it around the drum, and stall out, if the friction didn't catch the straw on fire first.

The founders of Frontier came up with the idea to modify the drum and paddle design so it would also act as fan. Voila, the torrents of air developed by this design blew the material behind and away from the drum solving the problem. We continued working with the US Dept. of Ag, and Oregon State University on their quest to compost this material. Our further tests proved that this same aerating action was highly beneficial in every composting operation. Because the principles of composting have not changed since the beginning of time, Frontier continues this design in every windrow turner we make from the largest to the smallest.

Because these grass seed fields were spread out all throughout the Willamette Valley of Oregon, transporting this large machine became a severe hindrance. Lowboys, permits and other restrictions made moving these machines expensive, clumsy and sometimes damaging. The only logical solution was to create a machine that would become its own trailer. To accomplish this, the frame design needed to be modified to handle the stresses that will be incurred during 65 MPH highway speeds and the grueling act of driving on uneven fields. Both the fifth wheel and rear axle assemblies had to detach and reattach in a simple and timely manner. Once the semi truck drops the turner off, it takes one man twenty minutes to take from the self-trailering mode to the windrow or from the windrow to highway mode. These detachable trailer assemblies have all the lights, brakes and axles to meet highway standards in both Canada and the US. From that day to this, Frontier's truss design has withstood the stress of bouncing down highways all over North America.

The unmatched mixing ability caught the eye of the soil bio-remediation industry from our beginning. With several process patents, the Frontier Windrow Turner, called the "Microenfractionator" has left its mark on the entire bioremediation industry.

There is very little a Frontier cannot do.


"Careful mixing of different kinds of material before building a windrow is no longer necessary; we merely layer the materials and run the Frontier windrow turner through the windrow. The paddle design not only optimizes aeration, but it assures thorough mixing. Thorough mixing is also a help in re-establishing families of microbes which may be destroyed by the high temperatures in the centers of the windrow."

"I just wanted to let you know that I got the O&M manual today. I also wanted to let you know that your turner is one serious piece of equipment. It has completely changed how we operate. We have had to change or modify about 75% of the process, simply because we are putting more product on the ground, and because of the dramatically increased efficiency of the turner. One of the best purchases we ever made. Thanks for all your help."

"Results of trials with other equipment encouraged us to use the new Frontier straddle-type windrow turner which had a dramatic effect on our process. ...the mechanical mixing prevented clods from forming. The process time to compost the material also dropped from almost seven months down to 45 - 60 days."

"We offer a product that sells for over $190.00 yd3.We take great pride and meticulous care of our material. If it weren't for the Mighty Mike's unequaled ability to mix and aerate our material this level of quality would be impossible. It is the core of our business. We have two of these turners and their trouble-free operation is a huge benefit. We do not have to fix it before we can use it. It is by far the best turner I've ever seen."

"Organix has been successfully managing compost operations on multiple dairies in the Northwest for over a decade. Our clients demand efficiency and performance. Sometimes we are making a finished product called Power Plant for retail sales, others are making bedding material, and some operations even compost all the mortalities.
Dealing with manures on any CAFO is a sensitive issue. No matter what the demand, the Frontier has always performed. One 12' tow-behind has been operating 12 – 16 hours a day every day on multiple sites for over a year. Other than routine maintenance, it has performed flawlessly. We have just ordered a second one to help handle the growing demand for our service in that same region. Rugged is an understatement for the Frontier windrow turner. These machines have become a vital part of our entire operation."
