Not only had to be a more effective way of establishing a winter grain crop that simply broadcasting seeds in the ground and then the plow, reasoned Andrew Metson.
"I felt so useless in terms of manpower, fuel and machinery to make a pass with an air drill and then have two tractors pulling plows to set seed underground," he says.
Based near Ongar, Essex, Mr Metson farms not only in their own right but also offers a steel fabrication and welding. Two years ago was devoted to the construction of a bean drill could operate directly on the seed rather than stubble, to the required depth and leave a flat surface - all in one pass.

For the element of culture we chose to use a semi-mounted Sumo Trio 4 million, which was equipped with seven legs and had two rows of discs and a subsequent press.
"The idea was to use the legs as the blades and seed-eating tire steel tubes welded to the back of the teeth," he explains. "I aim to place the seed at a depth of about 18 cm."
A deposit of seed metering unit and fan, was obtained from a pneumatic drill and this was rejected Vicon mounted on the rear end of the Sumo Trio. A PTO hydraulic drive, which once powered a sprinkler Chaviot, was brought to power the fan unit.
"One of the biggest challenges was to decide how to handle the measurement system in his previous life had depended on a set of wheels of the land," says Mr. Metson. "With the hopper mounted now much higher, running on a wheel on the ground and it was not practical. Instead, I decided to take a walk outside the friction of the press."
This agreement was not without its problems, however, due to the fact that the drive wheel was turning in the opposite direction - a problem to be solved by tying the string to a second pinion to reverse the rotation.
"Having done all this, I was very concerned that the jockey wheel does not find enough grip on the press conference and the accuracy of the measurement system suffering as a result," he says. "I considered some solder terminals to the press and even fill the water wheel to increase weight, but seems to be working fine as is."
And then, with everything arranged in the measuring department of the seed, he realized that the positioning of the drive wheel meant he would be crushed when the attachment is folded for transport.
"Now I had to put traction on a telescoping shaft using a hydraulic press to pull it toward the center so that the wings could rise" he says. "It was a bit complicated but it works."
Hopper capacity increased capacity from 0.5T 1.25T quite low for a more viable by adding an extra 50 cm (20 inches) stockboard to him, along with a flip-over.
The entire drill unit was designed to be a removable drive attached to the frame grower to only four points - two at tensioning hydraulic jacks. Mr. Metson said to last approximately one hour to remove about two hours and stick to - the largest assembly time required to try to remember how it all fits together, he insists.
In the first design, the seed is blown through a tube of diameter 15 cm (6 inches) to a distribution point in the front of the application. From here, 5 cm (2 inches) of pipe feeds the seed of the seven bars.
"I took the head of the score distribution using two disks that were once used by the drill Vicon" he explains. "Portfolio separated by a strip of metal welded to create a circular cavity, all you needed was for seven wells to be drilled in the base at regular intervals and the tubes connected."
It was not a major problem and although everything appeared to be 20 feet of pipe of the measuring system at the head of distribution. When the exercise was raised at the end, the hydraulic system pressure also extended a small ram drive wheel up to the seed meter off the press - so the seed flow stopped during the spin .
The reduction of the bit in the work of connecting the unit and the seed began to be measured in the feeding tube again, but the problem was that I was taking a big measurable amount of time to go to the bars and on the While there, the drill is well on its way to the field. Similarly, to reach the ropes, the seeds continued to flow for some time after drilling had been raised.
"It was a real problem for me and one that taxes the brain in the early hours," he says.
Eventually, however, the solution came to him. I was going to use a system that provides a constant source of seed measured in the front of the cutter, and when the drill was in the headers and the seed was not necessary to be able to shift back to the hopper.
"Even if I say so myself, it was a beautiful solution that meant the seed metering unit did not have to be stopped and all I needed was a deviation flap was removed - a rope - through when the drill increased to make the seeds of reflux over a return pipe to the hopper. "
With this new agreement, the time from seed to reach the gates was such that the exercise can raise and lower the top brand rather than a few feet before or after it.
So how do the exercise in the field? Working the clay medium but reasonably dry, clearly had the potential to offer some of the challenges in wetter conditions, the drill passed through the land with some vigor with each of the 360 ​​hp provided by a Fendt 936. To run at a depth of about 20 centimeters (8 inches), the operating speed was 12kph.

Seed placement was good - 170kg/ha seeding rate clearly finds its mark and the finished surface, but not a table, was the level necessary to go further with sprayers and fertilizer spreaders. It was surprisingly quick tip despite the extra length of practice and, with the Fendt Auto-orientation and headland management systems, operator input was relatively low.
Mr. Metson acknowledge that you have achieved what you set out to do, which was to reduce the costs of implementing a crop that needs to be used for three tractors, two plows, a 6 meter drill three operators to achieve.
The Bean Machine in action. Based on Sumo Trio 4m, used an air system Vicon drilling waste - and no little ingenuity, in the name of its designer.

Andrew Metson with the latest update of your drill - a system that reduces the time required for seeds to be delivered to the bars when drilling resumes after a headland turn.
Unit for the unit of measurement of the seed is taken from a friction in the press. There was concern whether it would be sufficient grip, but all is well, the reports of Mr. Metson.
The seed is done through a tube welded to the back of the leg that places the seed grower at a depth of about 20 centimeters (8 inches).
