Zetor HORTUS HS Series Operator's Manual page 50

The PTO shaft will not rotate if either of the two switches is in ''OFF'' position. The following table explains
how the PTO operates at the two different (Manual & Auto) positions of the PTO control switch with the PTO
''On / Off'' switch in the on position.
First select the specified speed for the PTO by using the PTO shifter on the LHS, below the driver seat.

The table above shows the PTO safety features. When the indicator light on the dashboard is blinking,

it indicates to the operator that the PTO is in the 'ON' position, but does not temporarily rotate either
because the clutch pedal is depressed or because the implement is lifted off the ground, or both. The
PTO starts to rotate immediately when the clutch pedal is released and / or the implement is lowered
to the ground.
The operator must ensure that there are no people in the area around the tractor when the indicator

light is blinking, as rotating parts of some of the implements can cause injury to persons standing near
the tractor.
Stopping the PTO, when lifting the implement from the ground together with a position check,

prevents damage to the implement or PTO.
WARNING: If the PTO control switch is in the manual position, the PTO does not stop even
when the clutch pedal is pressed. When working with a rotary implement on hard ground, the 'PTO
ON / OFF' switch must be set to the 'off' position to stop the PTO. If it is not in the 'off' position, the
rotating blades of the implement leaning against the hard surface can set the tractor into motion, so
that an accident may occur, which can result in serious injuries or death.
Warning:
Extra precaution must be taken to clear the area of bystanders / onlookers when using PTO

driven implements. The rotating blades of the implements can cause serious injuries on
contact. The warning that is indicated by the blinking PTO monitor is to make the operator
aware that the PTO is in on position and will instantly start rotating if the clutch pedal is
released or implement is lowered or both.
In no case the specified rotating speeds indicated by the implement manufacturer be crossed

as the same can lead to serious damage to the tractor / equipment and can lead to serious
injuries to persons around.
