also in Hilly terrain and wet harvesting conditions


Brought up on a small family farm in the Angus Glens, Scotland, I persuaded my father to buy a second hand combine harvester, not just to use on our own crop, but as combines were not all that common at that time, I reckoned I could take on extra acres from some neighbouring farmers. The first combine was a Massey-Harris 726 with petrol/TVO Morris commercial engine, only 2.75 metre cut, cost £600.

In 1961 after a successful season, we purchased a Massey-Harris 780 diesel, 3 metre cut, cost £800, in order to keep up with increased demand which had taken our acreage to some 300.

In 1964 we looked to buy a new combine and we chose a Clayson M103 with 3 metre header, Ford 6 cylinder engine, cost £2,630. Combines were becoming more popular and the local dealer (James Mackintosh of Friockheim) sold 22 machines that year. It was when I was introduced to the service engineer, the late Peter Mann, that I gained what was to be a proper knowledge of how to take the maximum output from a combine harvester. His opening words were “never use first gear, turn wind to maximum, open top screen full, bottom screen 75% open, drive combine into crop to maximum capacity for 50 metres. Stop, make inspection of grain sample in tank, close bottom riddle a little if too much rubbish and keep a close watch thereafter”. It worked and proved to me that going slower does not mean a better sample.

We had the same success with John Deere combines and then in year 2000 we purchased a New Holland TX36, 6 shaker combine on the recommendation of the now retired New Holland Sales Manager (Martin Brown), who now resides at next farm to us.

It has always been my belief that many combines are very much under utilised and a further experience after meeting Stephen Wallace of Wallace Technology confirmed my theory. Stephen introduced me to the Agri-Broker power screen sieves during the Royal Highland Show in Edinburgh, 2001. He was so emphatic that the sieves would allow the combine to achieve at least an increase in capacity of 15%, he offered me a full compliment of sieves with payment at end of harvest! Needless to say, they achieved exactly that as in that season we started harvesting a 63 acre field at 3pm finishing at midnight, an average of 7 acres per hour in spring barley. We regularly can achieve, with a 6 metre header, forward travel of 6 km/h i.e. 22 tonnes of spring barley per hour. We used these sieves for nine seasons then changed them over to our current New Holland TX68+ combine and as you will see from our DVD, we continue to enjoy outputs far greater than similar machines.

To sum up, I would strongly advise that farmers and managers consider the benefits of all of the Agri-Broker products as a step to increased performance and overall cost savings. Combine manufacturers should do likewise, but of course if that were to be the case their sales would drop by 15%!

Agri-Broker Grass Seed Harvesting Specialist:
“Since 2003 we have had 98-100% combine cleaned grass seeds when using Agri-Broker Sieves, together with speed improvement and almost nil losses.

Each year we have saved approximately 4000,- pounds Sterling /80 Hectar Grass Seeds resulting in increased earnings due to the minimal cleaning costs.”

ALFA GRE Rounded Louvre Sieves and Chaffers since 1970

With narrow spacing: aggressive shaking with uplifting dirty parts exiting through fast wind resulting in instant and even sieving process.



Bottom Sieves with narrow spacing:

12 or 18 or 24mm opening with 38mm long Agri-Broker CZ5.I Louvre or 36mm long Agri-Broker GRE-Louvre

„When harvesting 3.500 - 4.000 Tons per Year only 6 Tons of residual dirty parts had to be separated before storing. Because of this extremely low residual quantity it was unnecessary to use the cleaning facility anymore.”

Note: all the threshed grain is separated and cleaned by the instant Cascade falling through the AB-Top Sieves on to the first 90-110 cm.

Summary of 12 combines monitored harvesting in the same field the same Winter Wheat:

AB - The Sieve box Top and Bottom Sieves when shaking in opposite directions act similarly to the Lung i.e. expanding and contracting ca. 35mm.

For very broad and evenly chopped straw distribution
also when wet or green – For all Combines

One set of AB High-Quality-Choppers serves up to 800 Ha

Efficient straw humification and improved field hygiene

The angled bottom part of the pairs of the premium Choppers help to produce an intensive wind which pushes the chopped straw out on both sides on to a long trajectory.
Not using Agri-Broker Airjet-Choppers leaves uneven straw distribution

When using the Agri-Broker Walker Assistant Vibrotines: "It can be clearly seen that there is a very intensive up-lifting and loosening of the straw together with an increased throughflow - also with green Oilseed Rape Straw. Visible Improvement in Chopping efficiency. Even more even distribution when swathing straw therefore enabling faster collection by the Round Bale Press.”
