TRACTOR SET UP
There are a few things that can be done with the tractor set up to ensure the smooth efficient operation of
the Twin merger. The drawbar should be set up at least 17 inches off the ground. This may require the
drawbar to be “flipped”. This gives more clearance between the pole and left head wind gurad for opening
and closing. Also the drawbar should be extended in the farthest position to allow for easier turning. The
three point arms should be taken off the tractor to keep them from hitting the hydraulic shut-off valve
located at the front of the pole. The tractor must be equipped with a 1000 RPM 1-3/8” 21 spline PTO
shaft. The tractor should have a seven pin electric plug.
PRE-OPERATION
While in the transport position, check entire unit carefully before first operation. Tighten bolts, set screws,
and chains that might have come loose in handling. Lubricate as explained in the lubrication guide.
Install drawbar extension on drawbar. Install hitch pin (B) and rotate pin lock (C) over hitch pin. Tighten
3/4” nuts to 150 ft. lbs. (204N-m). Nuts will secure pin lock and hold extension tight to the drawbar.
Dimension “A” should be the same on each side as shown.
Attach Merger to tractor using 1” hitch pin (D) provided and install safety-locking device.

PRE-OPERATION (Continued)
Slide pump on receiver and secure with pin (E) provided and install safety-locking device.
Slide spring loaded locking collar (F) on PTO yoke rearward, and slide yoke onto the tractor PTO shaft.
Release spring loaded collar. Be sure the pins fall into the grove of the tractor PTO shaft and collar
snaps forward into position. CAUTION: Do not use steel hammer to aid in joining PTO parts.
Remove weight from lift jack and place in storage position (G).
Connect four hydraulic hoses to the tractor (9’ pickups). Two hoses open and close the machine and the
other two supply oil to the electric/hydraulic solenoid valve for pickup heads.
Connect six hydraulic hoses to the tractor (12’ pickups). Two hoses open and close the machine, two
hoses raise and lower the left hand head and two hoses raise and lower the right hand head.

HYDRAULICS
The tractor hydraulic system should have a minimum flow of 5 GPM and a minimum pressure of 2000 PSI.
This system is used to operate the pole cylinders and the cylinders controlling pickup heads. The PTO
driven self-contained hydraulic system on the Merger provides oil to the hydraulic motors operating the
pickup belts and cross conveyor belts. The Merger pole is the hydraulic reservoir. In case of a blown
suction hose, shut off tractor PTO and turn off valve located at the front of the pole. The fans for the oil
cooler radiators are located on the merger pole must be turning properly to keep oil cool during merger
operation. The oil filter should be replaced once a year and the oil should be replaced every other year or
when the oil becomes discolored.
-12-
PRE-OPERATION (Continued)
Plug the joy stick control box cord into the main wiring harness on pole (9’ head). Attach control box to
a convenient place on the tractor. The tractor hydraulic circuit must now be locked in the open position
to provide oil flow to the electric valve on merger. Operation of joysticks will now control raising/lowering
and sliding of pickup heads. * Connect plug for cross conveyor reversing / shut-off valves.
Run pickup and conveyor for several minutes to ensure proper assembly and lubrication. Successful
operation will be achieved by periodic adjustments and experience of the operator. Make sure to read
and understand the adjustments.
Check tires and inflate to recommended pressure. The front two tires (H) should be inflated to 90 PSI,
the gauge wheel tires (I) should be inflated to 50 PSI. The rear tires (J) should be inflated to 36 PSI.

OPEN/CLOSED CENTER SYSTEM
VALVE CONVERSION (9’ HEAD)
The valve is supplied in a closed center configuration
suitable for use in circuits utilizing pressure compensated
pumps. For use in gear pumps (open center) circuits, a
conversion is required. The valve outlet section has a “T”
port, as shown in Fig. 1 with the tank return line plumbed into
it. This internal plug must be removed for open center
operation. The tank return line may then be plumbed into the
port. Be sure to save the hex plug for possible future use.
OPERATION
LOAD LEVELER
After engaging the PTO, the Load Leveler (B)
automatically transfers a portion of the machine
weight to the rear carry wheels, and to the
tractor drawbar.
B
CROSS CONVEYOR
TheTwin Merger can be set up to merge hay to the
right, left, or right and left.This can be done by
moving the toggle switches on the control box.
These switches can not be moved from one direction
to the other in one continuous motion. They are
designed to stop in the center position. Momentarily
relieving pressure on the switch will allow it to then
be moved in the other direction. Bringing both
switches to the center position will stop both cross
conveyors. The pick up heads will still be operating.
When both cross conveyors are stopped, this allows
the operator to pick up small amounts of hay and store
it in the cross conveyor. The operator can then
go back to a windrow and select the direction of
travel and resume merging. The pickup head and
cross conveyor speed should be controlled by
adjusting the tractor throttle. By controling the speed
this way, the hydraulics will run at a cooler
temperature. Opening and closing should be done
on level ground and not while moving.
Fig. 1

ADJUSTMENTS
TAIL WHEEL
The tail wheels are located at the rear of the merger.
Located on each tail wheel pivot spindle is an
adjustable brake assembly. Adjust the brakes by
tightening bolt (A). The brakes should have enough
tension to prevent zig-zag motion, but still allow the
wheel to pivot when making corners. Improper
adjustment will cause severe tire wear and damage
to merger.
OPERATION (Continued)
-14-
TRANSPORT LOCKS
There are three transport locks on the merger. All locks should be used when transporting the unit, and
must be in the open or storage position when operating the merger. The transport locks (ball valves) (C)
for the heads are located at the cylinders that are used to raise and lower the heads. These cylinders are
located to the “inside” of the heads. The pole transport lock is located near the bend in the pole (D).
Transport speed should not exceed 20 M.P.H.
FRAME GAUGE WHEELS
There are two frame gauge wheels used on each
Twin Merger. Their sole purpose is to keep the
frame from contacting the ground in uneven
terrain. The picture to the right shows the frame
gauge wheels in the working position. The gauge
wheels must be raised to transport merger.
Failure to do so may cause damage to the frame
gauge wheel assembly. To raise gauge wheels
remove pin (E) raise wheel and insert pin back
into the same hole.

-15-
PICKUP ADJUSTMENT
Pickup belts may be adjusted by tightening the take up bolt (B) located on both ends of the pickup. The
flange bearing bracket bolts (C) must be loosened before adjustment, and tightened after the desired belt
tension is attained. Proper belt tension will be achieved when 1-1/2” of slack can be pulled in the center of
the two outside belts with minimal resistance. DO NOT tighten pickup belts excessively. Over tightening
may cause damage to belts or rollers. Loose belts will cause unnecessary tooth wear and breakage.
Pickup height may be adjusted by adjusting the
gauge wheels located at both ends of the heads.
Pull pins (D) and rotate gauge wheels until proper
adjustment is achieved. Proper adjustment will allow
teeth to run 1/2” above the ground. Excessive tooth
wear and breakage will occur if teeth are touching
the ground. Adjust both sides equally.
WIND DEFLECTOR ADJUSTMENT
The wind deflector can be raised for heavy crop
conditions, or lowered for lighter crops. The
adjustment is made by repositioning the pins
located on each end, in the front of each pickup
head as shown (E). Overall transport width can be
made considerable narrower, by removing pins
(E) at each end of the pickup head.
The entire wind deflector can be pivoted
backward, toward the cross conveyor. To lock into
transport position, reinsert pin (E) into hole
(F) shown.

ADJUSTMENTS (Continued)
CONVEYOR ADJUSTMENTS
The cross conveyor belt tension can be adjusted
by tightening the take up bolts (G) located on the
two rollers located at the center of the machine.
Proper tension may be achieved by compressing
the springs to 3-1/4”.
OPTIONAL ACCELERATOR ADJUSTMENTS
Adjust cam (H) evenly on both sides of the
accelerator to tighten chain and square accelerator
to frame. Improper adjustment will cause excessive
chain wear.

OPTIONAL EQUIPMENT
The optional cross conveyor stop was designed
to allow the operator to stop both cross conveyors
and still have the pickup heads operate. This
allows the operator to pick up small amounts of
crop and store this crop on the cross conveyor to
later discharge onto a windrow.
The optional accelerator is a attachment that is
needed when merging windrow cuts larger than
16’. The accelerator gently moves the crop over
the additional distance needed for the larger
windrow cuts.

LUBRICATION
There are 42 grease fittings on your base merger. There are two zerks on the optional accelerator. If these
are lubricated properly and often enough, it will prolong the life of the merger. Grease daily during normal
use and before and after storage and after power washing. Use a good grade of high quality grease.
Make sure grease comes out around the shaft on the sleeve type bearings. On the sealed ball bearings,
grease should be added slowly until a slight bead forms at the seals indicating the correct amount of
lubricant. Wipe off excess grease to prevent accumulation of grit around the bearings. During normal use,
oil roller chains daily (Optional accelerator only).
(8) Cross Conveyors - one on each pillow block
bearing (2 each on ends, 4 in the center
