Owners of Great Plains’ Simba cultivators are better placed than owners of other brands this spring because they own machines which are more adjustable than their competitors, says Adrian Hartley, Chief Design Engineer.
But before they get any machine out of the shed for spring field work he suggests they use a spade to examine the soil and determine just how much cultivation they should do.
His message is especially relevant for those farmers who had to abandon cultivations last autumn and may be working in the spring for the first time in a number of years:
“The water that has been lying in the fields this winter is proof of widespread structural problems and compaction.
“Farmers must find out how deep this is before trying to repair it. And once they have repaired it they need to work in a way that minimises the risk of causing fresh problems.
“This spring the complete adjustability of Simba machines will come into its own.
“Being able to adjust the working angle of the cultivation discs; the relative working depths of discs and restructuring legs; and being able to fit different styles of legs and wings means our machines are the most flexible and capable on the market.
“The important thing to remember when trying to restructure damaged soils is to detect how deep the problem is and set the machine to the correct depth to remove it while avoiding working below the critical depth.
“Users are likely to have to run the working discs at narrower angles than they might have done in the autumn, because the soil may be wetter than it is normally and they do not want to over-work it.
“That narrower angle will increase the discs’ chopping action, which will be a benefit if the stubble and trash has been laid on the surface over the winter”.
