Sound Pressure; Sound Power; Vibration Level - Toro 74450TE Z400 Z Master Operator's Manual

• Do not mow near drop-offs, ditches, steep banks
or water. Wheels dropping over edges can cause
rollovers, which may result in serious injury, death
or drowning.
• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding
and loss of control.
• Do not make sudden turns or rapid speed changes.
• Use a walk behind mower and/or a hand trimmer
near drop-offs, ditches, steep banks or water.
• Reduce speed and use extreme caution on slopes.
• Remove or mark obstacles such as rocks, tree limbs,
etc. from the mowing area. Tall grass can hide
obstacles.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Avoid sudden starts when mowing uphill because
the mower may tip backwards.
• Be aware that loss of traction may occur going
downhill. Weight transfer to the front wheels may
cause drive wheels to slip and cause loss of braking
and steering.
• Always avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades and
proceed slowly off the slope.
• Follow the manufacturer's recommendations for
wheel weights or counterweights to improve stability.
• Use extreme care with grass catchers or other
attachments. These can change the stability of the
machine and cause loss of control.
