Robotics & Automation

Innovate UK offers funding for Robotics and Automation projects in Agriculture and Horticulture (Registration closes 15/03/2023)


Electromechanical linear actuator rams are used on farm machines such as combines. We may be able to repair failed linear actuators.


Electrohydraulic solenoids are used on many agricultural machines to activate hydraulic circuits controlling hydraulic oil flow to hydraulic rams and motors. Proportional solenoids may be electrically controlled by a pulse width modulated (pwm) signal from a controller. Solenoid on/off time may be controlled by the electrical pulse width and duty cycle. PWM signals may be checked using diagnostic equipment such as an oscilloscope to measure voltage / current over time.

Electric linear actuators

Electric linear actuators are used to position and move other components, a typical example used in agriculture would be an electric actuator used to open and close a slide chute to control flow of materials.

Visual Imaging Systems

Visual imaging systems for the agricultural industry fall into several categories including close circuit television (CCTV) camera systems used to monitor harvesting operations, security, and animal welfare. Due to difficulties with colour image detection, robotic imaging systems may recognise different shades of grey to build up image patterns.

Starter Motors

We supply and repair a wide range of starter motors to fit agricultural tractors and engine driven machines. We have sourced some of the harder to locate starter motors by cross reference based on dimensions. We supply parts for starter motors such as solenoids, armatures, starter drives, and brushes.

Alternator - Dynamo - Electrical Charging System Components

We supply a wide range of alternators , dynamos , and autoelectrical repair parts to fit agricultural machinery.
A common problem affecting farm machinery alternators is build up of debris such as chaff and dust drawn into the alternator causing premature failure. Older machinery can suffer from worn out alternator brushes and rotor bearings. We can supply engineers with a range of alternator voltage regulators, diode packs, rotors, and bearings to enable repair of alternators. Correct component location will require oem alternator manufacturers part numbers from the label on your old alternator.

Older farm tractors may be fitted with dynamo type charging system and current / voltage regulator.

Farm Trailer Lights

We supply a wide range of aftermarket farm trailer lights including
Tail light units
Front rear & side marker lamps
Single core and multicore cables
Wiring junction boxes
Wiring plugs and sockets.

Most 12 volt farm trailer lights are wired using a 12N wiring system however we often find variations on agrimachines.

12N Wiring Colour Code

Pin 1 Yellow wire Left hand indicator
Pin 2 Blue wire Rear Fog light (if fitted)
Pin 3 White wire Common Return (often chassis ground)
Pin 4 Green wire Right hand indicator
Pin 5 Brown wire RH tail lamps, RH side markers,
Pin 6 Red wire Brake lights stop lamps
Pin 7 Black wire LH tail lamps, LH sidemarker lamps, Number plate lamps.

Some vehicles are manufactured with light duty wiring to rear lamps and canbus wiring systems. Such vehicles may require fitment of a seven way bypass relay if installing trailer towing electrics.
