SZB Standard

The SZB’s main frame has been constructed from special steel. The Slootsmid distributor, as is the case on all Slootsmid injectors, has been placed in an elevated position. This position, together with the unique non-blocking hoses, ensures a perfect, uninterrupted flow from the distributor down to the ground. As they descend the hoses are distributed evenly across the bottom width. The dual elements are suspended by means of maintenance-free articulated hinges so that they can adjust to the contours of the ground. The discs in the elements have a diameter of 250 or 300 mm and they are placed 180 mm apart. When the injector is raised, the rubber slurry outlets are automatically closed by means of a mechanical system. A hydraulic closing system is available as an option.

SZB Standard

The SZB Standard is particularly suitable for farmers wishing to extract maximum benefit from their slurry. The SZB Standard is a robust, simple machine which ensures a professional fertilizing result. This injector is designed to be strong yet light. This means it can be placed behind most tanks. The SZB Standard’s strong points include its simplicity and durability. This gives you a machine that is cheap to run but will last you a long time.

Maximum benefit from your slurry

Because of the small disc the injector exerts very little pressure yet delivers the fertilizer very efficiently into the soil onder the most difficult of conditions. The narrow coulter makes a right-angled slit and the unique rubber slurry outlets ensures that the slit is filled properly without any spillage. In this way the fertiliser is delivered directly into the top layer of the soil where it is absorbed and used to optimal effect. 


Unique non-blocking hoses

The unique uninterrupted length of hose produces a perfect flow of slurry from the distribution unit to soil. The hoses have no constrictions along the way that could cause blockages. The new, specially shaped discharge boots ensure a perfect flow of fertilizer, even at high speeds. The discharge boots are closed by an automatic system.  

Clever design

The use of special steel and clever design have made it possible for us to construct a sturdy, reliable frame that still has the advantage of being surprisingly light. The frame is fully galvanised which guarantees its durability. The dual element with its two thin discs gives a smooth ride and is able to adjust to track and soil contours very efficiently. Its unique suspension and minimal swivel points also contribute to excellent durability, while wear and tear is reduced to a minimum. The discs rotate independently of each other and have greasable tapered bearings. The spring pressure is adjustable and the option of a hydraulic system is also available. The clever features of the dual element make pulling the injector along lighter work. This means that the machine requires less power to penetrate the soil, which in turn means less fuel consumption. 

Attention to safety

Elements shielded during transport

 The SZB has a substantial, easy-to-see lighting strip and a mechanical or hydraulic locking system for when it is being transported. When the frame arms are folded up the outer elements are automatically shielded by a safeguard mechanism. Because it’s so compact, the injector mostly does not sticks out beyond the width of the tank of tractor.


The SZB slurry injector is fitted with a variable hitch headstock in 4 point version.
