Spreader - spreading machines for tractors – Tracon l Bucher Municipal


tractor spreaders with
single auger feed system


high-value spreading machines for tractors

Available in container sizes 0.5 m³ up to 2.5 m³.

The gritting automation of the proven series Tracon and the new series Tracon plus are best suitable for assembly on tractors with three-point hydraulic due to the low container design.
The vehicle-device combination is optimally adjusted for your usage needs in the communal area.

You can choose between dry material- or wet salt spreader, one-chamber or twin-chamber design.

Reliable and performant spreaders
Reliable and performant spreaders

The gritting machines of the Tracon range are renowned for their excellent reliability, first-class service and attractive price-performance ratio. The excellent equipment finish and the use of tried-and-tested components are further proof of the great technical expertise built into our machines.

High quality and long lifetime
High quality and long lifetime

The high proportion of stainless steel ensures even the basic amenities for a long lifetime of the gritter machines (skid plates, spreading disc and all fasteners are stainless steel). The device security cover is also made of stainless material.

LED work light

The LED work light is mounted by the spreading group and provides very bright white lighting in the work area. The housing is dust- and damp-proof.

High number of stainless steel parts

The gritting machine has a special paintwork and the skid plate, spreader disc, feet sockets and all fasteners are made from stainless steel. The spreader is also available as a full stainless steel version (optional).

Equipment box

Equipment box

The equipment box offers optimum protection for the hydraulic block, the junction box and the black box. The box is made of steel and damp-proof sealing.

Closed spreading group

Closed spreading group

The spreading group of the Tracon and Tracon Plus series is a closed scattering system. The feeding of the material from the container down to the spreader disc is largely sealed against moisture. The spreader disc made of stainless steel with a special plastic cone ensures a homogeneous distribution pattern over the entire spread width 1 - 8 meters.

Spreader distributor

Spreader distributor

The spreader distributor distribute the salt on the street and is consisting of a stainless steel spreader disc with a special plastic cone and a plastic spreader cover.

Single-/Twin auger system

Single-/Twin auger system

The spreaders of Tracon and Tracon Plus series have a continuous auger (see figure). Optionally, the Tracon series can be supplied as double chamber spreader. In this case, the automatic spreader has two auger conveyors - one for salt and one for grit. In all series, the auger conveyors have different sized coils to ensure an uniformly emptying of the scattering container.

Run dry protection

Run dry protection

The run dry protection is part of the optional liquid salt equipment. The pump switches off immediately if the tank is empty and so damages will be preventing.

Sensor technology

Sensor technology

Only available together with the Ecosat control panel. This compares the set-point and actual values of the spreader disc, the auger and the liquid salt pump. The sensors are sealed to IP 67 protection rating.

Equipment safety cover

The equipment safety cover is mounted in the hopper and has a light construction made of highly resistant GFK material.

Optional liquid salt pump unit 

The liquid salt pump unit promotes the liquid salt to the spreading disc and consisting of a hydraulic pump, a large size filter, a 3-way valve and a C connector. The piping is consisting of stainless steel.


Optional liquid salt tank

The liquid salt tank is mounted on the side of the spreader and contain the liquid salt. The tanks are made from highly resistant polyethylene with filler and connection for a level sensor.

Optional folding roof 

The folding roof protects the container content from rain and snow. It consists a stainless steel frame and high-strength PVC cover.


Optional rotary beacon

The rotary beacon is available on request in various flashing and strobe lighting systems.

Optional warning signage 

The winter service warning signage is about retroreflective material for rear and side warning signage.

Optional control unit Ecosat

Control unit Ecosat

Latest generation microprocessor control systems for all kind of spreaders, with maximum flexibility in programming and visualizing the different spreading parameters: width, asymmetry and dosage depending on the vehicle speed. Six different tools in all-in-one control box.

Optional electronic spread pattern programmer 

ESBV - Electronic spread pattern programmer

A powerful servomotor and a potentiometer enable the symmetric and asymmetric setting of the spreading pattern with using the control panel. The servomotor is waterproof to IP 67 protection rating.

Optional electronic spread control 

The spread control is mounted on the disc protection. Contactless, infrared technology is used to monitor spreading. The housing is 100% waterproof to IP 67 protection rating.

Control unit Ecosat

Latest generation microprocessor control systems for all kind of spreaders, with maximum flexibility in programming and visualizing the different spreading parameters: width, asymmetry and dosage depending on the vehicle speed. Six different tools in all-in-one control box.


Ecosat has an integrated GSM/GPRS module (option) which enables operational data transmission. In case of bad coverage (e.g. tunnels) the data are logged and will be transmitted as soon as the connection is back.


Ecosat integrates (option) a multi-constellation GNSS receiver which supports GPS or GLONASS improving the localization performance in terms of accuracy, continuity, availability, and reliability.


The Ecosat stores daily operational reports and global counters which can be downloaded or printed via serial connection.


A serial connection between the infrared sensor and the Ecosat allows automatic changing of the spreading dosage based on the road temperature.


On spreaders with electrical control of asymmetry, this function provides full control of the direction of spreading. The screen display varies according to the type of asymmetry: with or without feedback. 5 pre-set positions can be selected.


In this section of the working area, it is possible to monitor the level material in the tanks, the solid quantity in the hopper and also the fuel level (only for equipment with auxiliary engine).


The vehicle speed can be simulated from 5 to 90Km/h in steps of 5. This feature is useful when there is no tachometer connection, when the connection is damaged or when the spreader has to work while the vehicle is not moving.

Alternative control unit EcoTron / EcoTron Plus

The EcoTron / EcoTron Plus control panel unit is characterised by its compact dimensions and high-resolution graphics display. The EcoTron / EcoTron Plus performs sensor-based and monitoring of distance-dependent screw conveyor speeds and pump speeds, and also saves all relevant working data. A serial USB interface port is available for easy exporting of data.


Compact dimensions: Width 175 mm, Height 115 mm, Depth 65 mm.


Two rotary knobs with precise click-in positions.


Large colour display 95 mm x 55 mm, dimmable.


Enlarged display area if the quantity to be spread or the width of spread changes.


Simple and secure adjustment of the most important spreading parameters: Metering width and asymmetry.


Backlight function keys for secure operation of the main functions even under bad lighting conditions.


User-friendly control interface which presents all the important information in a clearly structured format - optimum design based the latest best practice.


Continuous recording all working data together with the overall information can be exported to an external storage medium (UBS stick) via the serial interface port.


Distance-dependent spreading by sensor-based monitoring of the screw conveyor speeds and pump speeds.
