Designed to Withstand Tough Conditions

Main Gearbox & Driveline
All MDS spreaders utilize a simple 540 rpm PTO drive. Contained within the cast-iron case are the components to drive the spreading discs and hopper agitator. This drive system has been designed for long life with minimal maintenance, as the gearbox oil only requires changing every 10 years under normal operating conditions.

High-Quality Finish
All KUHN mounted fertilizer spreaders go through a proven multi-step finishing process that includes mechanical and chemical cleaning followed by a top-quality powder-paint application and baking. This ensures optimal corrosion and scratch resistance, fading resistance, acid resistance, and increased abrasion durability.


Improved Material Flow

Hopper Design
The hopper on the MDS .2 features an octagonal design. Similar to the design of our larger Axis fertilizer spreaders, the angles improve material flow to the centrally located metering outlets. This reduces bridging and promotes complete hopper emptying with all types of granular materials and seeds. A rotating agitator at the bottom of the hopper also helps to keep material flowing freely. Optional agitators are available for special applications such as grass seed, powdery materials, or sticky materials.

Direct Flow Control (DFC) System
All MDS spreaders utilize the Direct Flow Control (DFC) system for rate control. For a given working width and ground speed, changing the opening of the metering slides by a given percentage will change the application rate by the same percentage. On the .2 and .2 W models, the metering slide opening scales are mounted on the front of the spreader to keep them cleaner and for comfortable viewing from the operator’s seat.


Tailored to Meet Your Operation's Needs

MDS .2 Metering Outlet Controls
Hydraulic Outlet Control
Precision control of the metering outlets is essential to ensure that the right rate of fertilizer or seed is applied to the field. Each outlet is controlled by its own dual-acting hydraulic cylinder connected to the tractor’s SCVs. The size of each outlet opening can easily be monitored on the indicators visible from the operator’s seat.
E-Click Outlet Control
For enhanced control, choose this electric metering outlet control option. One actuator for each outlet ensures reliability and precision, all controlled through the simple E-Click control box. Just like the hydraulic version, convenient indicators for monitoring the outlets are visible from the operator’s seat.

Spreading Discs
MDS spreaders can spread up to 80’ (pass-to-pass working width) depending on disc selection and the properties of the material. In general, oddly shaped and/or less-dense granules will be restricted to narrower patterns.

Adjusting the length and position of the paddles on the discs creates the ideal spread pattern for each material. M1C discs come standard and are designed for working widths up to 59’. Optional M2 discs feature redesigned paddles optimized for 60’-80’ spread patterns. Both disc types offer the option of VXR hard-coated paddles for even greater durability.

MDS .2 W Weighing System
The hitch and main frame of the MDS .2 W are connected by a pair of electronic weigh cells. These weigh cells measure the weight of the product leaving the hopper at a rate of 100 times per second, which allows the Quantron controller to adjust the flow factor and change the application rate every two seconds. The weigh cells also eliminate the need to perform a calibration test to establish a baseline flow factor prior to startup. Finally, the weigh cells inform the operator of the amount of product remaining in the hopper to optimize reloading cycles.

MDS .2 W Quantron A Controller
Standard on all MDS .2 W models is the proven Quantron A controller. A color screen displays all the main machine functions, including application rate, ground speed, load remaining, area counter, and more. The physical buttons are easy to operate when bouncing over rough ground. To provide accurate variable rate control, the Quantron can hook up to a GPS receiver using cables offered as optional equipment.
