Diagnostic Tools That Can Keep Your Farm Equipment Moving

Feb 9, 2024 | News

Keeping farm equipment in good working condition enhances efficient and productive farming operations. If you are looking for diagnostic tools for farm equipment, you can find them at David’s Heavy Duty Tool Sales. Here are some diagnostic tools that can keep your farm machines moving:

OBD-II Scanners (On-board Diagnostics)

OBD-II (On-Board Diagnostics, version 2) is a standardized system that monitors and reports on the performance of various systems within the farm equipment. In farm machinery, OBD-II systems are integrated into the engine control module and electronic control units. These systems monitor engine speed, fuel mixture, and emissions. By tracking emission-related parameters, you can make sure your farm equipment meets environmental standards and regulations.

On-board diagnostics at David’s Heavy Duty Tool Sales generate Diagnostic Trouble Codes (DTCs) when they detect issues within tractors or harvesters. DTCs indicate a problem with fuel, ignition, or emissions control that helps to tell you what needs maintenance. Advanced OBD-II scanners log and store historical data, helping farmers and technicians track the performance of the equipment over time. Many OBD-II scanners connect to smartphones or tablets via Bluetooth or Wi-Fi, enabling users to view and analyze data using mobile apps.


Oscilloscopes are valuable diagnostic tools for farm equipment for identifying issues related to sensors, actuators, and ignition systems. This tool examines the waveform emanating from the ignition coil, spark plugs, and other ignition system components. Oscilloscopes help in analyzing the quality of electrical power supplied to farm equipment. They can detect voltage fluctuations, spikes, or irregularities in the waveform, allowing farmers to implement measures to protect sensitive electronic components from damage.

Choose digital storage oscilloscopes from our collection that allow technicians to capture, save, and recall waveforms for later analysis. These tools have a digital display that provides a clear and detailed view of waveforms. The user interface is often intuitive and user-friendly, with on-screen menus and controls for easy configuration. Digital storage oscilloscopes come with USB ports, LAN connectivity, or other interfaces for data transfer and remote control.

Digital Multimeters

Digital multimeters (DMMs) are handheld tools for measuring electrical properties, such as voltage, current, frequency, resistance, continuity, and capacitance in farm machinery. Technicians can use DMMs to assess the condition of batteries in farm equipment. They can measure the voltage of the battery and check its internal resistance. Low voltage or high internal resistance may indicate a weak or failing battery needing replacement.

Digital multimeters help diagnose sensor issues by checking the electrical signals they generate. Technicians can identify sensors requiring replacement or adjustment by comparing actual sensor readings with expected values. The DMMs can measure alternating and direct currents that show the current flow in different parts of the electrical system. Excessive or insufficient current can indicate problems, such as a malfunctioning component drawing too much current or a break in the circuit causing a loss of current.

Pressure Gauges

Pressure gauges measure fluid or gas pressure within a closed system. They provide a visual indication of the force exerted by the fluid on the walls of the container. Digital pressure gauges provide a numerical readout of the pressure level. They may offer additional features such as data logging, customizable units, and alarms for irregular pressure conditions.

These diagnostic tools help to monitor the health of hydraulic and pneumatic systems. Sudden drops or fluctuations in pressure can indicate problems such as leaks, clogs, or failing components. Continuous monitoring lets operators and maintenance personnel detect issues early, preventing equipment damage and downtime. Our kits include a set of hoses and adapters to connect the pressure gauge to the fuel system. These components can fit various fuel system configurations, making the kit compatible with multiple farm machines.

Video Inspection Scopes

Video inspection scopes, also known as borescopes or inspection cameras, are tools for examining hard-to-reach areas within farm machinery. They consist of a flexible or rigid tube with a camera at the end, allowing technicians to visually inspect components, identify potential issues, and perform maintenance. Our video inspection scopes contain adjustable LED lights on the camera head to help illuminate dark spaces during inspections.

The camera has waterproof features to manage damages from liquid or moisture exposure. Digital video scopes come with articulating tips, allowing the user to steer the camera in different directions. The articulation feature is useful for inspecting complex and hard-to-reach areas. When choosing video inspection scopes, check the battery life and buy one with rechargeable batteries.
