Before Operating Checking the Engine Oil The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started. Crankcase capacity is approximately 3.5 quarts (3.3 l) with the filter. Use high-quality engine oil that meets the following specifications: API Classification Level Required: CH–4, CI–4 or higher.
Filling the Fuel Tank The engine runs on No. 2 diesel fuel. The fuel tank capacity is approximately 6 gallons (22.7 l). 1. Clean the area around the fuel tank cap (Fig. 25). 1 2 Figure 25 1 Figure 26 1. Fuel tank cap 1. Radiator screen 2. Remove the fuel tank cap. The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze. Check the level of the coolant at the beginning of each day before starting the engine.
3. If the coolant is low, remove the reserve tank cap and add a 50/50 mixture of water and permanent ethylene glycol antifreeze. Do not overfill. Alternate fluid: Mobil EAL 224H This is vegetable–oil based biodegradable oil tested and approved by Toro for this model. This fluid is not as resistant to to high temperatures as standard fluid, so install an oil cooler if required by the operator manual and follow recommended fluid change intervals with this fluid.
Checking the Tire Pressure 1 The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. The correct air pressure is: 2 • Front tires: 8–12 psi • Rear tire: 8–15 psi Checking the Reel-to-Bedknife Contact Each day before operating the machine, check the reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable.
Operation Think Safety First Please carefully read all the safety instructions on pages 3 thru 7. Knowing this information could help you and others avoid injury. The use of protective equipment, such as, but not limited to, for eyes, ears, feet, and head is recommended.

Starting and Stopping the Machine Starting Important The fuel system may have to be bled if any of the following situations have occurred: • Initial start up of a new engine • The engine has ceased running due to lack of fuel. • Maintenance has been performed upon fuel system components; ie. filter replaced, etc. 1 Refer to Bleeding the Fuel System, page 27. Figure 34 1. Seat adjusting handle Important fluid. Fuel Shut-Off Valves 1.
3. Close the fuel shut-off valves before storing the machine. The safety interlock system prevents the machine from moving unless: • The parking brake is off. Bleeding the Fuel System • The operator is seated. 1. Position the machine on a level surface. Make sure the fuel tank is at least half full. • The functional control lever is in Mow or Transport. The safety interlock system prevents the reels from operating unless the functional control lever is in the Mow position. 2.
Setting the Reel Speed Preparing the Machine for Mowing To achieve a consistent, high quality–of–cut and a uniform after cut appearance, it is important that the reel speed control (located on the manifold block under seat) be correctly set. To assist in aligning the machine for successive cutting passes, it is suggested that the following be done to the No. 2 and No. 3 cutting unit baskets: Adjust the reel speed control as follows: 1. Measure in approximately 5 in. (12.
Mowing Procedures 5. Cut down on operating time and ease lineup for the next pass by momentarily turning the machine in the opposite direction, then turning in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right. This will assist in getting the machine more quickly aligned for the next pass. Follow the same procedure for turning in the opposite direction. It is a good practice to try to make as short a turn as possible.
spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation. Towing the Traction Unit In case of an emergency, the machine can be towed for a short distance (less than 1/4 mile [0.4 km]). However, we do not recommend this as a standard procedure. Important Do not tow the machine faster than 2–3 MPH (3–5 km/h) because the drive system may be damaged. If the machine must be moved a considerable distance, transport it on a truck or trailer. 1.
