Hydraulic Flow Diagrams T raction Forward The traction circuit of the hydraulic system consists of a hydrostat connected in a closed loop circuit to three or - bital vane wheel motors. Hydraulic fluid losses are de- signed to occur from case drain leakage of the traction pump (P1) and bleed of f from the right wheel motor (M1).

T raction Reverse The traction circuit operates essentially the same in re- verse as it does in forward. However , there are a few dif- ferences in operation. When the traction pedal is pressed to the reverse posi- tion, the linkage from the pedal positions the swash plate in the traction pump so oil flows out of port A.

Rev . B Sand Pro 2020/3020/5020 Hydraulic System (Rev . A) Page 4 – 16 T roubleshooting The table that follows contains information to assist in troubleshooting. There may possibly be more than one cause for a machine malfunction. Refer to the T esting section of this Chapter for precau- tions and specific test procedures.
Sand Pro 2020/3020/5020 Hydraulic System (Rev . A) Page 4 - - 17 T roubleshooting (cont.) Problem Possible Cause System operates in a jerky manner when starting. External control linkage is misadjusted, disconnected, binding, or damaged. Charge valve in hydrostat is defective.
Rev . B Sand Pro 2020/3020/5020 Hydraulic System (Rev . A) Page 4 – 18 T roubleshooting (cont.) Problem Possible Cause Attachment raises, but will not stay up. Lift cylinders leak internally . Neutral position check valves in lift valve leak. Difficult to make slight changes when raising and lowering the at- tachment (Sand Pro 2020 and 3020).
T esting The most effective method for isolating problems in the hydraulic system is by using hydraulic test equipment such as pressure gauges and flow meters in the circuits during various operational checks (See the Special T ools section in this Chapter).

Procedure for Wheel Motor Efficiency : Note: Over a period of time, a wheel motor can wear internally . A worn motor may by–pass oil causing the motor t o b e l ess ef ficient. Eventually , enough oil loss will cause the wheel motor to stall under heavy load condi - tions.
Adjustments Adjust T raction Pedal for Neutral If the machine “creeps” when the traction pedal is in the neutral position, the traction cam must be adjusted. 1. Park the machine on a level surface. Turn the en- gine off. 2. On the SP 2020/3020 , pivot seat upward and re- mov e engine shield.
Adjust T raction Pedal for Forward (SP 5020) If the jam nuts on the control rod are loosened or if the pedal is removed, adjusted traction pedal for forward. 1. Park machine on a level surface and turn engine of f. 2. Make sure pump is in neutral. 3. Loosen jam nuts on the control rod.
Sand Pro 2020/3020/5020 Hydraulic System (Rev . A) Page 4 – 30 Adjust Lift Lever (SP 2020/3020) The lift lever should be adjusted if the attachment does not float (follow ground contour) properly during opera- tion. 1. Park machine on a level surface.
Service and Repairs Check Hydraulic Lines and Hoses nozzles that eject hydraulic fluid under high pres- sure. Use paper or cardboard, not hands, to within a few hours by a doctor familiar with this W ARNING Keep body and hands away from pin hole leaks or search for leaks.
13. After the hydraulic system starts to show signs of fill, actuate lift control lever until the lift cylinder rod moves in and out several times. If the cylinder rod does not move after 10 to 15 seconds, or the pump emits abnor - mal sounds, shut the engine off immediately and deter- mine cause or problem.
Change Hydraulic System Fluid and Filter The hydraulic system filter must be changed initially af- ter the first 8 hours of operation. Thereafter , it must be changed every 400 hours of operation or yearly , which - ever comes first. Use a genuine T o ro oil filter for replace- ment.

Special T ools Order special tools from the TORO SPECIAL TOOLS Some tools may also be available from a local supplier . AND APPLICA TIONS GUIDE (COMMERCIAL PROD- UCTS) . Multimeter The meter can test electrical components and circuits for current, resistance, or voltage.
T roubleshooting CAUTION Remove all especially rings and watches, before doing any electrical trouble- cables unless the test requires battery voltage.
Starting Problems (continued) Problem Possible Causes Engine cranks, but does not start. Wiring to start circuitry (see Wiring Schematics) is loose, corroded, or damaged. 10 ampere fuse is missing or open (SP 5020). Ignition switch is faulty . Fuel solenoid is faulty .
Electrical System Quick Checks Battery T est (Open Circuit T est) Use a multimeter to measure the voltage between the battery terminals. Set multimeter to the DC volts setting. The battery should be at a temperature of 60 to 100 _ F (16 to 38 _ C). The ignition key should be off and all accessories turned off.
Component T esting For accurate resistance and/or continuity checks, elec- trically disconnect the component being tested from the circuit (e.g. unplug the ignition switch connector before doing a continuity check).
Hour Meter IMPORT ANT : Make sure to observe polarity on the meter label when testing. Damage to the meter may result from an improper connection. 1. Connect the positive (+) terminal of a 12 VDC source to the positive terminal of the hour meter . 2. Connect the negative (–) terminal of the voltage source to the other terminal of the hour meter .
Starter Solenoid NOTE: Prior to taking small resistance readings with a digital multimeter , short the test leads together . The me - ter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal re - sistance of the meter and test leads.
Service and Repairs NOTE: For more component repair information, see the Briggs and Stratton V anguard Service and Repair Manual for 4–Cycle, V–T win Cylinder , OHV Engines. Battery Storage If the machine will be stored for more than 30 days 1. Remove the battery and charge it fully (see Battery Service).
