Two-Speed Pto Systems; Operating With Stationary P.t.o. Equipment - New Holland T7030 Operator's Manual

TWO- -SPEED P.T.O. SYSTEMS
General Information
Generally speaking, P.T.O. driven equipment not
having a high power requirement is designed to run
at 540 P.T.O. rev/min and will have a 6--spline female
coupling. A P.T.O. shaft speed of 540 rev/min is
obtained at an engine speed of 1950 rev/min.
Equipment having a high power requirement is
designed to operate at 1000 P.T.O. rev/min and will
be provided with a 21--spline female coupling. With
the 21--spline shaft installed, run the engine at 2178
rev/min to provide a P.T.O. speed of 1000 rev/min.
Tractors with 2--speed 540E/1000 P.T.O. have the
advantage of running low power 540 P.T.O. driven
equipment at a reduced engine speed by selecting
540E on the lever. See page 3--31 for P.T.O. and
engine speeds.
IMPORTANT: Implements with a high power
requirement should be operated with the 1000
rev/min. P.T.O. (21- -spline shaft). If it is necessary to
use the 6- -spline shaft (at 540 rev/min.) to operate
implements having a power requirement of more
than 75 horsepower,
recommended that the implement is fitted with a slip
clutch to avoid damage to the P.T.O. output shaft and
other tractor components.
NOTE: When required, change the P.T.O. shaft to
suit the operation and equipment in use, as
described under 'Changing the P.T.O. Output Shaft'
on page 3- -35 .

Operating with Stationary P.T.O. Equipment

Before operating static P.T.O. equipment, make sure
the tractor is safely positioned and the parking brake
is applied. Sitting in the seat, engage P.T.O. drive
and, observing the instrument panel display, set the
appropriate speed.
NOTE: On tractors fitted with Engine Speed
Management, it may be prudent to use the ESM
function to maintain a constant speed if the load on
the P.T.O. is subject to variations.
On leaving the tractor seat an intermittent alarm will
sound for approximately 5 seconds and the amber
warning light will illuminate. If the alarm sound is a
constant tone, check to ensure the parking brake is
firmly applied.
