STRAUTMANN Primus: What Sets It Apart

Innodur® technology

The optional INNODUR® abrasion-resistant elements significantly extend the life of the IMS mixing screw. These 5 mm thick and 100 mm wide stainless steel elements are attached to the screw coils by overlapping screws and can be retrofitted if required.

New-Generation Smart Feed Cab

The new Smart Feed Cab is designed to give the operator a clear view of the entire work area and the machine’s key components. The large glass area, heated windshield, ergonomic controls, and integrated control terminal make the cab a comfortable workspace, even during long work shifts.

High-Quality Feed Preparation

Two IMS (Intensive Mix System) mixing augers with a patented blade adjustment system can be adapted to different feed rations. This enables fast, uniform mixing that preserves the feed structure, while reducing power requirements and mixing time.

Exceptional maneuverability in tight barns

The standard 4-wheel steering system, crab steering mode, and rear-end swing control ensure excellent maneuverability even in narrow farm aisles. Its compact design allows for comfortable operation in areas where larger machinery struggles.

Universal helper – IMS (Intensive Mix System) mixing auger

IMS mixing screw – Versatility and durability for any job. Thanks to the patented IMS blade adjustment system, the mixing auger can be precisely adapted to specific operating conditions. The robust and low-maintenance angular drive ensures a long service life even under demanding operating conditions.

Low energy consumption
Preservation of feed structure
Homogeneous mixing
Energy-saving short mixing time

Adjustable front auger tip/scraper

Thanks to the adjustable scraper belts, even the smallest ingredients are reliably collected from the ground and mixed evenly.

Solid foundation

The IMS mixing screw is based on a very robust and durable gearbox. Stability and long maintenance intervals are ensured by large tapered roller bearings, double sealing and a capacious oil chamber.

Efficient mixing

Ideally matched mixing screw geometry and distance to the tank wall – for fast and uniform mixing.

Innodur® technology

The optional INNODUR® abrasion-resistant elements significantly extend the life of the IMS mixing screw.

Stainless steel elements with a thickness of 5 mm and a width of 100 mm.
Screwed to the propeller strands with overlap.
Can be installed at a later date.

A reinforced version of the IMS mixing screw with 20 mm thick coils is available on request, providing a 50 % longer lifetime (which means 50 % less wear and tear).

Different knife options

Individual chopping knife options for different feeds
Easy to put on.
Straw chopping knife.
Scraper: provides additional mixing effect and improves feed movement.
Roll shredding knife: excellent for shredding rolls.
Root vegetable shredding blade: additional shredding of beets or potatoes.

Magnet system

Highly efficient separation of metallic foreign bodies.
Optimal health protection of the cattle herd.
High efficiency due to direct and close contact with the mixed feed.

Stainless steel finish

In diets with a high corn content (>75% of dry matter in the total diet), the amount of aggressive lactic acid increases significantly. This acid corrodes the tank material and promotes the formation of rust layers. The stainless steel finish effectively protects the tank from this damage.

Stainless steel elements
1.5 mm thick and 90 cm high side wall elements
3 mm thick bottom plate
Optional 3 mm thick side wall elements are also available

Increased safety – rear overhang control

With rear-end lateral protrusion control

First, the axes are activated synchronously to prevent swaying
Automatic switch to four-wheel steering system
Ensures safe movement away from, for example, silo walls

Without rear-end lateral protrusion control

Collision hazard

Constantly monitor feeding with the Strautmann Data System (SDS)

Strautmann Data System (SDS) – is a new platform for all data flows generated by machinery – with its help or within it. One of the main SDS modules for self-propelled feed mixers – feeding software.

SDS allows you to create recipes and set unloading points. A clear and user-friendly component and recipe management system can be operated from both a computer and a mobile device. One or more users can access the recipes and perform feeding exactly as instructed. The system can be used by multiple users simultaneously to perform mixing and feeding according to specific requirements.

First feed dispensers records all important technical and weighing data and synchronizes them with this system. This allows you to easily analyze, evaluate and adjust the feeding process. SDS is a valuable tool that helps optimize feeding, improve animal productivity and health, while reducing resource consumption.

A special advantage for farms with multiple locations is the SDS Premium version:

This option allows you to create, manage and analyze data for multiple farms separately and use more recipes. It provides the ability to compare planned and actual indicators, as well as record the working time of each employee and each farm - which helps ensure clear documentation and more accurate billing.

In the future, the functionality of SDS will be further expanded - it is planned to integrate maintenance interval management, as well as provide more transparency to customers, for example, in the area of warehouse management.
