Electric Clutch Operation
The 3PYPA Planter has two or three clutches in the seed
meter drive system:
•
Hydraulic drive planters have 2 clutches.
•
Ground drive planters have 3 clutches.
A clutch enables or disables groups of row units. The
information in the table on the next page is normally
preset at the factory for your planter configuration.
Refer to Figure 55 (depicting the left group shut off)
The switches Left
/ Center
/ Right
correspond to
the left wing row units, center section row units and right
wing row units respectively. The Center switch has no
function on hydraulic drive planters.
The Master
switch controls all row units, regardless of
drive type. For all switches, “OFF” (down) removes
power from the clutch, disengaging that set of row units.
When any switch (plus Master) is ON, the LED for that
switch illuminates steadily.
Electric Clutch Lock-Up
In case of electric clutch failure, an electric clutch can be
mechanically engaged.
Refer to Figure 56 and Figure 57
1. Remove the rubber plugs
from the oil shield
disc
to allow access to the lock-up holes. Plugs
simply push out away from the clutch side.
2. Align the cutouts
with the holes
.
3. Insert the M8-1.25 x 14mm long metric bolts
.
If you observe half the hole obstructed by a metal
disc
, you are not at a cutout.
If the entire hole is obstructed by a metal disc
, you are
not at a cutout.
When at a cutout, the bolt will screw in with minimal
resistance until the bolt head reaches the clutch face.
4. Reinstall the plugs so they are not lost.
Use only the provided 14 mm length bolts. Longer
bolts will damage the clutch. Shorter bolts may not
effect a lock-up.
