The Quadro M2 Plus was introduced in 2005. Danish company Bogballe uses the in-spinning way of spreading, ie the discs rotate from the outside in. This apparently gives more overlapping between the two discs and less chance of a bad spread pattern.
Working width: 12-42m
Hopper: Standard from 1,800-litre to 3,000-litre
Price tested: £13,495

CV field test: 3.7%, CV after adjustment not required
After setting the spreader according to the manual, the Bogballe had a CV of 3.7% – the lowest of all machines in the test without correction.
Y: 0.24%, CT: 16.6%
This is located on the right-hand side, with disc rotation reversed to give out-spinning spreading and the fertiliser exiting through a hole in the vanes.
The results were good, with only 0.24% of the fertiliser falling beyond the boundary.
Although the CT-score was good at 16.6%, there was a clear peak in terms of quantity applied on the right-hand side, while the left-hand side of the spreading pattern fell short. The CT-value doesn’t reflect this.
Bogballe’s Calibrator Zurf computer was introduced last year. Although it lacks a colour screen, the console itself is easy to use and clear.
On screen, there’s a lot of information, such as how many metres you have left before the hopper is empty (a little bit like the range function on your car) and area covered.
It’s equipped with a USB port and spreading chart data can be read automatically and transferred between tractor and office.
The Quadro is very easy to set. Find the name of the fertiliser either in the manufacturer-supplied tables or on the internet.
Then enter the application rate, flow factor and working width. You can also opt to analyse the spreading characteristics of the fertiliser yourself (like Vicon) and determine what setting is most appropriate by using the website.
The tilt of the spreader should be set at 4°, which you do by adjusting the top linkage. An arrow indicates the gradient.
The Quadro M2W requires the operator to use seven trays for the field tray test; three positioned to the left, three to the right and one in the middle.
The collected fertiliser is then compared with the bar graphs shown in the manual. Equal distribution indicates the spread pattern is good, however if the outer trays contain fewer granules than the inner, the discharge point above the disc has to be adjusted so that the working width increases.
If the outer trays have more, simply reduce this as the spread is too wide.
Very tidy throughout and design quality is good. At 673kg, it’s a light machine. There are no sharp edges and it’s well-painted.
Disc drives are sealed and maintenance-free and there are very few corners where dirt can linger, while mudguards protect any mud from being flung up.
All elements of the machine that have contact with fertiliser are made from stainless steel, apart from the vanes themselves, which are made from hardened steel instead.
Steps on the outside of the hopper and a set inside make it easy for the operator to gain access.
The spreader itself is mounted on a parallel subframe, on which there is one weighing cell and a reference sensor which accounts for the machine’s gradient and any shocks when operating.
The agitator is mounted so that it can both rotate and move both back and forth.
