The seed placement principle of the MS metering units is based on the control of the depth by the front gauge wheel and planting with shoes.
The clod remover clears the future planting line of clods or stones whilst the gauge wheel presses the soil and controls the depth.
The shoe opens the furrow (or the furrows) at a depth defined by the front gauge wheel.
The intermediate press wheel, adjustable in pressure, presses down the seeds into the bottom of the furrow for regular and rapid plant emergence (except MS versions B and D).
The scrapers (retractable if necessary) scrape fine soil over the seeds (except MS version B).
The rear wheel closes the furrow around the seed for optimal seed germination.
The MS metering unit has been specially designed for market gardening crops. Seed drop precision, regularity of depth, emergence dynamics and the simplicity of adjustment are the main assets of the MS metering unit.
The MS metering units are delivered, in standard version, with a 1,5-litre extension. If required, the units can be supplied without extension or with a 3-litre hopper.
The heavy-duty parallel linkage is mounted on interchangeable bushings. For soft ground, a relief spring is on option.
The MS metering unit head is equipped as standard with a manual row cut-off.
On MS metering units, the depth control is made with the front wheel.
The wheels mounted on ball bearings, are available in different models according to your requirements and according to the version of metering unit.The depth adjustment is made using a hand wheel. A scale enables to check the precision of depth adjustment when planting.
The MS unit shoes can be removed and have an interchangeable tip. Different models of shoes are available according to the type of planting (single line, double lines or strip) and according to the type of soil (rounded tip, short wings, long wings,….).
The MS units are equipped with intermediate press wheels for pressing the seeds down into the bottom of the furrow and also to improve the seed-to-soil contact (except MS B and D units). The pressure on the ground of this press wheel can be adjusted.
The MS units are equipped with scrapers in the standard version for closing the furrow (except on MS B units). These scrapers can be individually adjusted in height and are retractable.
Different models of wheels are proposed for closing and firming the furrow. The pressure on the ground of these wheels is adjustable.
For light, supple soils, a double adjustable relief spring helps to relieve the metering unit.
Quality planting depends first of all on a good metering system. This is why MONOSEM uses all their know-how so as to propose a precise, simple and very reliable metering system. This quality of manufacture will enable you to plant the smallest seeds with great precision.
The metering box made from bronze ensures a perfect seal with the disc without risk of the phenomenon of static electricity.
The stainless steel discs 1 mm thick are very rigid. The agitator, fixed on to the disc stiffens the unit. The changing of the discs is easily made without tools. A complete range of discs for all precision seeds is available.
The brass scraper avoids doubles. A spring on the metering box cover maintains the selector perfectly in place against the disc for optimal selection, even with small seeds.
The cover in alloy is specially designed for planting with a minimum of seeds. A fiber gasket provides a seal between the disc and cover.
The distribution system is easily accessible, for both adjustments and control. A large transparent window allows for control of the selection after the selector.
After the seeds have dropped, a jet of air removes any dust and residue of seeds that could get stuck in the holes of the discs.
The selection adjustment is made using a single lever which is easily accessible on the top of the metering boxes. The quality and the precision of the MS metering boxes enables an identical adjustment on all of the units.
