Hydraulic System Operation Coring Head Raise/Lower The hydraulic pump supplies hydraulic pressure for raising and lowering the coring head. The pump is belt driven. The hydraulic pump takes its suction from the hydraulic reservoir which is part of the pump assembly. During conditions of not lifting or lowering the coring head, flow from the hydraulic pump goes to the lift control valve and is by–passed directly back to the pump reservoir.
Special Tools Order these special tools from the TORO SPECIAL TOOLS AND APPLICATIONS GUIDE (COMMERCIAL PRODUCTS). Hydraulic Pressure Test Kit Part Number: TOR47009 Use to take various pressure readings for diagnostic tests. Quick disconnect fittings provided attach directly to mating fittings on machine test ports without tools. A high pressure hose is provided for remote readings. Contains one each: 1000 PSI (70 Bar), 5000 PSI (350 Bar) and 10000 PSI (700 Bar) gauges.
Troubleshooting The cause of an improperly functioning hydraulic system is best diagnosed with the use of proper testing equipment and a thorough understanding of the complete hydraulic system. A hydraulic system with an excessive increase in heat or noise has a potential for failure. Should either of these conditions be noticed, immediately stop the machine, turn off the engine, locate the cause of the trouble and correct it before allowing the machine to be used again.

Special Tools Multimeter The multimeter can test electrical components and circuits for current (amps), resistance (ohms) or voltage. NOTE: Toro recommends the use of a DIGITAL Volt– Ohm–Amp multimeter when testing electrical circuits. The high impedance (internal resistance) of a digital meter in the voltage mode will make sure that excess current is not allowed through the meter. This excess current can cause damage to circuits not designed to carry it.
Troubleshooting For effective troubleshooting and repairs, you must have a good understanding of the electrical circuits (see Chapter 9 – Electrical Diagrams) and components used on this machine. CAUTION Remove all jewelry, especially rings and watches, before doing any electrical troubleshooting or testing. Disconnect the battery cables unless the test requires battery voltage. If the machine has any interlock switches by–passed, they must be reconnected for proper troubleshooting and safety.
Starting Problems (continued) Problem Possible Causes Engine cranks, but does not start. Circuit wiring to engine magneto is grounded (see Chapter 9 – Electrical Diagrams). Circuit wiring to carburetor solenoid is loose, corroded or damaged (see Chapter 9 – Electrical Diagrams). Engine stop relay is faulty. Ignition switch is faulty. Engine or fuel system is malfunctioning (see Chapter 3 – Engine). Engine may be too cold. General Run Problems Problem Possible Causes Battery does not charge.
Electrical System Quick Checks Battery Test (Open Circuit Test) Use a multimeter to measure the voltage between the battery terminals. Voltage Measured Battery Charge Level 12.68 v (or higher) Fully charged (100%) Set the multimeter to the DC volts setting. The battery should be at a temperature of 60o to 100o F (16o to 38o C). The ignition key should be in the OFF position and all accessories turned off.
Check Operation of Safety Interlock System The Safety Interlock System of the Greens Aerator ensures the following operations: CAUTION Do not disconnect interlock switches. They are for the operator’s protection. Check operation of the switches daily to make sure the interlock system is operating correctly. If a switch is not operating properly, adjust or replace it before operating the machine. Interlock switch operation is described in the Greens Aerator Operator’s Manual.
Component Testing For accurate resistance and/or continuity checks, electrically disconnect the component being tested from the circuit (e.g. unplug the ignition switch connector before doing a continuity check). NOTE: See the appropriate engine Repair Manual located after Chapter 3 for engine component testing information. NOTE: Electrical troubleshooting of any 12 Volt power connection can be performed through voltage drop tests without disconnecting the component.
Engine Stop Relay The Greens Aerator uses a relay for grounding the engine magneto and thus, stopping the engine. This relay is located under the console (Fig. 7). Testing NOTE: Prior to taking small resistance readings with a digital multimeter, short the meter test leads together. The meter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads.
Interlock Lever Switches The two interlock lever switches are located on the handle (Fig. 9). The lever switches are normally open and close when the lever is raised to the handle. The interlock lever switches are used to permit engine operation when the coring head is lowered and also allows the traction drive lever to be retained in the engaged position. 1 Testing 1. Unplug the switch connector from the machine harness. 2.
Traction Interlock Switch The traction interlock switch is attached to the shift plate at the front of the aerator (Fig. 10). The greens aerator uses the normally open (center) and common (ground) terminals of the switch (Fig 11). 2 2 When the gear shift lever is in a gear, the switch plunger is depressed and the switch should be closed (continuity). When shifting gears, the switch plunger extends and the switch should open (no continuity).
Coring Head Switch Assembly The coring head switch assembly monitors the position of the coring head (raised or lowered) for correct aerator operation. This switch includes two (2) normally open ball switches, one (1) normally closed ball switch, a spring loaded plunger and a housing (Fig. 13). 2 1 3 6 4 The plunger in the switch assembly is extended when the coring head is lowered. In this position, the switches are in their normal states (two are open and one is closed).
Clutch Solenoid The clutch solenoid is used in conjunction with the traction interlock switch, the coring head switch assembly and the interlock lever switches in the Greens Aerator interlock system. When the clutch solenoid is energized, the solenoid plunger rotates a latch which retains the traction drive lever in the engaged position for continued traction drive operation as long as the solenoid is energized. 3 1 Testing 2 1. Make sure engine is off. Disconnect battery.
Engine Starter Solenoid The engine starter solenoid is attached to a bracket on the starter motor (Fig. 17). Testing 1. Make sure engine is off. Disconnect battery. Disconnect solenoid electrical connections. 5 2. Apply 12 VDC directly across the solenoid coil posts. The solenoid should click. Make sure resistance across the main contact posts is less than 1 ohm (continuity). 3. Remove voltage from solenoid coil posts. The solenoid should click.
Fuses The greens aerator uses two (2) fuses for circuit protection. 1 The fuses are held in individual fuse holders and have the following functions: 20 Amp Fuse: Protects main power circuit to ignition switch terminal B. The 20 Amp fuse is located behind the engine (Fig. 19). 5 Amp Fuse: Protects circuit to clutch solenoid. The 5 Amp fuse is located under the console cover (Fig. 20). Figure 19 Testing 1. 20 Amp fuse Remove fuses from the fuse holder for testing.
Diode Circuit Boards The Greens Aerator uses two (2) diode circuit boards that are located under the console cover (Fig. 21). One of these circuit boards has three (3) diodes while the other board has four (4) diodes. The three diode circuit board (Fig. 22) provides logic for the interlock system. Diode D3 on this board is not used. The four diode circuit board (Fig. 23) is used for circuit protection from voltage spikes that occur when circuit solenoids are de–energized. Diode D1 on this board is not used.
Service and Repairs NOTE: See the engine Repair Manuals located after chapter 3 for engine component repair information. Battery Storage If the machine will be stored for more than 30 days: 1. Remove the battery and charge it fully (see Battery Service). 2. Either store battery on a shelf or on the machine. 4. Store battery in a cool atmosphere to avoid quick deterioration of the battery charge. 5.
Battery Service The battery is the heart of the electrical system. With regular and proper service, battery life can be extended. Additionally, battery and electrical component failure can be prevented. 1 CAUTION 2 When working with batteries, use extreme caution to avoid splashing or spilling electrolyte. Electrolyte can destroy clothing and burn skin or eyes. Always wear safety goggles and a face shield when working with batteries. Figure 24 1.
Testing 1. To properly test a battery, perform a high–discharge test using an adjustable load tester. This is one of the most reliable means of testing a battery as it simulates the cold–cranking test. A commercial battery load tester is required to perform this test. 2. If a battery load tester is not available, the battery can be tested by conducting a hydrometer test of the battery electrolyte. IMPORTANT: Make sure the area around the cells is clean before opening the battery caps. A.
Charging To minimize possible damage to the battery and allow the battery to be fully charged, the slow charging method is presented here. This charging method can be accomplished with a constant current battery charger which is available in most shops. CAUTION Follow the manufacturer’s instructions when using a battery charger. NOTE: Using specific gravity of the battery cells is the most accurate method of determining battery condition. 1.

General Information Coring Head Operation The coring head of the Greens Aerator consists of a pivoting coring frame, two coring crank sets, tine arms with connecting rods to provide vertical tine motion, turf guards, tine holders and aerating tines. Drive for the coring head comes from the engine mounted pulley through a 3V section drive belt that is tensioned by a spring loaded idler pulley.
Coring Head Bearing Caps The Greens Aerator coring head frame includes several bearing caps used to position the power shaft and crank arms. Line boring of the coring head frame during manufacture determines location of the bearing caps. If any of the bearing caps are removed during repairs, they need to be reinstalled in the exact position that they were removed from. Matchmark bearing cap and frame location before removing a bearing cap from the coring head frame. 1 2 3 Figure 3 Coring Head 1.
