To turn your starter, electricity flows from the battery, through the ignition switch, and to the small terminals on the starter solenoid. This electricity causes an electromagnet inside the starter solenoid to connect the two heavy gauge wires and form a complete circuit. High amperage electric flow then goes through your starter, turning your engine’s flywheel.
The reservoir holds the fluid; in the case of our garden tractors, oil. The pump moves oil throughout the entire system. The valve directs oil to different hydraulic cylinders or motors. The Piston or Motor is where the final work is performed. A piston will move loads up and down, and a motor will rotate. All of the components are connected by hydraulic hoses or lines.
Measuring resistance can indicate the health of a component. For example we can determine if an ignition coil is healthy or not by measuring the resistance of its windings. To measure resistance, set your meter to Ω ohms resistance. If you need to select a range, select the smallest range normally 200 ohms. Place the red probe onto one of the small terminals of the ignition coil, and the black one on the remaining small terminal. Your resistance will then display. A normal ignition coil should read about 3.5 to 4 ohms. If your meter reads a much higher resistance it means your ignition coil may have a short and is faulty.
A hydraulic system is a simple, space efficient way of multiplying and transferring your engine’s power to multiple applications for your tractor. By utilizing hydraulics you can build a front end loader, backhoe, 3 point hitch, 3 way plow, a dump trailer and much more. The limits are in your imagination.
