Thoughts on using a JPH CT360 Windrow Turner.

To whom it may concern.
My name is Chris Cameron, I currently live in South-East Queensland, and I have been working with Biological Agriculture for over 50 years, working out how best to restore productivity to our ancient and weathered Australian soils. The problem, once understood properly, is not difficult. We lack Organic Matter, many essential minerals have been leached out over the eons, and we lack beneficial soil biology in most areas.
About 20 years ago I managed to make the jump from garden scale compost making up to paddock scale, as well-made compost, and what can be blended with it, will quickly reverse most of our problems. My first major work was done with an old end loader, slow and inefficient, but effective in the end. Output with it was very low.
Over the intervening years I have worked with six different Compost Turners of varying types, American, European, Australian Factory built, Australian “home built”, and am currently using a Queensland designed and built JPH CT360, a tractor pulled, PTO driven machine.
It is quite different in design to any of the Turners I have used previously, in that it does not have a huge counterweight and hydraulics that allow the turning mechanism to stand upright for transport. Initially I felt this may be a problem if I got “bogged” in a new windrow, but after having run through, effectively, 20K tons of material I have had absolutely no problem. Without the huge counterweight the machine is light and easy to manoeuvre, the way it folds in behind the tractor for transport is quick, easy, and effective. As there is not a huge weight of machine ever up in the air, it is also far safer to work around!
With the obvious exception of using a Loader to turn windrows, every Turner I have used in the past has had a habit of throwing heavy bits forward, causing some glass breakages on the towing tractors, and needing special screens to prevent this happening, restricting somewhat the clear view of what is happening behind.
The very different “tyne and paddle” design of the JPH machine greatly reduces this and I run safely with no screen and the tractor back window open to give me the most uninterrupted view of what is happening. This is a great development!
This same drum design and layout, which is so different from the majority of Turners, is extremely efficient in doing the 3 tasks needed of a Turner: complete inversion of the windrow, rapid reduction of particle size, and even incorporation of mineral additives, if these are used. Feedlot manure, my main feedstock, can arrive in huge chunks almost as hard as concrete and these are rapidly reduced to a fine texture.
One of the best features of this machine is its extremely low power requirement! The biggest machine I used in North Queensland a monster spanning over 5M needed over 300hp to drive it, and the tractor struggled. I am pulling this JPH CT360, with a small tractor with about 80 PTO hp and its in-cab readout reports I am using barely 30% of available power for a full-sized windrow! This is exceptional!
On the service and maintenance side, everything that needs regular service is easy to see, and access. This means that maintenance is not ignored because it is too hard to do regularly.
I am delighted with this machine and would have no hesitation in recommending it, or its “brothers”, and plan on using more in the near future.
