Section 1: Set-Up Requirements
Driveline Installation
The FMX and RMS model driveline is connected with a push-pin coupling
to the tractor and a shear bolt coupling to the implement. Refer to
Figure 1-1a Driveline with Push-Pin Coupling. The RMX uses a
push-pin coupling to the tractor and a 2-plate slip clutch to the implement.
The RMH uses a push-pin coupling to the tractor and a 4-plate slip
clutch to the implement. Refer to Figure 1-1b Driveline with Slip
Clutch Coupling.
To minimize torque on the driveline when starting up; remember to
always engage the PTO at a low engine RPM.
Note: If your Priefert implement is equipped with a friction clutch; then
it must go through a "run-in" operation prior to initial use and after long
periods of inactivity. (Refer to Slip Clutch Specifications on page 13) .
CAUTION
Tractor PTO shield and all implement guards must be in place at
all times during operation!
IMPORTANT: If you are switching tractors or going to use a quick
connect hitch then you will need to check the driveline maximum and
minimum lengths to ensure the safe operation of your equipment.
You may find it necessary to use different drivelines.
IMPORTANT: Before connecting the PTO Drivelines, clean and lubri-
cate driveline connection points. When checking PTO driveline mini-
mum length, it is important to have the tractor's PTO driveline level
with the implement's gearbox shaft. Engage the tractor's hydraulic 3-
point to raise or lower the lower arms until the implement's gearbox
shaft is level with the tractor's PTO Shaft.
DANGER
Priefert advises against the use of PTO adapters as these may
defeat the purpose of the master shield on your tractor. PTO
adapters create an unguarded shaft area between the tractor
and the driveline guards that may cause entanglement that may
result in serious injury or death.
DANGER
Do not attempt to operate your PTO driveline while it is
unguarded as this may cause entanglement that may
result in serious injury or death.
PTO Driveline:
Refer to Figures 1-2 to determine minimum and maximum operating
lengths on page 12.
The PTO driveline minimum and maximum lengths must be checked
prior to initial use or when using a different tractor or adding a quick
connect hitch and to ensure that the driveline is compatible with all
work conditions required by your Priefert implement.
When fully extended the driveline must have a minimum overlap of the
inner and outer shafts by not less than 1/3 the free length with both inner
and outer shafts being of equal length or not less than a 6" (76mm)
overlap.
Telescoping drivelines will have a variant in lengths due to changes in
o
the vertical angle of +20
due to uneven terrain or raising implement for
transport. It is very important not to operate your driveline with less
than the 1/3 free length or 6" (76mm) overlap as this may cause your
driveline to detach while in operation and pose a safety hazard to the
operator and possible damage to the tractor and implement.
1.
Attach implement to your tractor. (See "Tractor Hook-up", pg. 10)
2.
Adjust tractor top link until the implement gearbox input shaft is
level with tractor input shaft.
3.
Place tractor gear selector into park, turn engine off, set park
brake and remove key.
4.
Securely block implement in this position.
5.
Attach the PTO driveline to the implement's shaft:
For Driveline with slip clutch—secure by sliding the Slip clutch end
of driveline over the splined input shaft of the gearbox. Secure with
driveline yoke locking device. For Driveline with Shear Bolt—secure
by sliding the shear bolt end of the driveline to the implement's shaft
of the gearbox. If the driveline comes with a snap ring ensure that
this is locked into place and shear bolt is tight.
6.
Slide the opposite driveline yoke end over the tractor's splined
driveline shaft. Secure with driveline yoke locking device. The
driveline will require shortening if it is too long to fit between the
tractor and implement then continue with Driveline Adjustment.
If the PTO driveline fits the tractor and implement continue with
Slip Clutch Set-up Requirements.
7.
If the PTO driveline does not fit between the tractor and the imple-
ment continue with "Determining your operating lengths".
Determine your operating lengths:
1.Pull drive halves apart until fully extended, just before coming apart.
Record this measurement as A and subtract 6" (76mm) and record as
C measurement in your operator's manual.
2.Push the driveline halves together. Record this measurement as B
and add 1" (25.4 mm) and record as D measurement in your operator's
manual.
