Greasing The Spindles; Cleaning The Cooling Systems; Checking The Tire Pressure - Toro 74256 Operator's Manual

Where to Add Light Oil or Spray
Lubrication
Lubricate the machine in the following areas with spray
type lubricant or light oil. Lubricate every 160 hours.
Seat switch actuator.
Brake handle pivot.
Brake rod bushings.
Motion control bronze bushings.

Greasing the Spindles

The cutting unit must be lubricated weekly or every 25
hours. Refer to the Service Interval Chart on page 30.
Grease with No. 2 general purpose lithium base or
molybdenum base grease.
Important
Make sure cutting unit spindles are full of
grease weekly.
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Grease the three spindle bearings under the pulleys
until grease comes out the lower seals (Fig. 47).
4. Grease the fittings on the push arms (Fig. 47).

Cleaning the Engine Fins
Every 100 hours clean engine cylinder and cylinder head
cooling fins. Also clean around carburetor, governor
levers and linkage. This will make sure adequate cooling
to hydraulic pumps, motors and engine and will reduce the
possibility of overheating and mechanical damage.
1. Remove the panels from the engine shroud.
2. Clean the engine cooling fins.
3. Install the panels onto the engine shroud.

Checking the Tire Pressure

Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Fig. 50). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and caster wheels.
