Introduction
The Matador 7900 Windrow Inverter is designed to turn
and move hay swaths for a faster dry down. The Matador
utilizes a low prole, heavy duty pickup with extra width to
allow rapid operation with minimal leaf loss.
The moldboard of the Matador 7900 Windrow Inverter is
a patented design giving a 180˚ turn to the swath when
the machine is operated correctly.
These operating and maintenance instructions have been
compiled from extensive eld experience and engineering
data. Some information is general in nature due to un-
known and varying conditions. However, through experi-
ence and these instructions, you will be able to develop
operating procedures suitable to your particular situation.
Please study this manual from beginning to end BEFORE
operating your new Matador 7900. Pay special attention
to the Safety section in this manual and the safety cau-
tions on your equipment. Should anyone else operate
this equipment be sure that they understand ALL safety,
operating and maintenance information presented in
this manual.
The terms ‘right’ and ‘left’ as used throughout this manu-
al are determined by facing the direction the machine will
travel when in use.
AgLand Industries Inc. is a Canadian owned and oper-
ated company located in central Canada, in the province
of Manitoba. AgLand was founded in 2001 by a group of

Operating Safety
▪ Ensure that all components in the hydraulic system
are kept in good condition.
▪ Replace any worn, cut, abraded, attened, or
crimped hoses and/or metal lines.
▪ Do not attempt any poorly executed repairs to hy-
draulic lines, ttings, or hoses by using tape, clamps,
or cements. The hydraulic system operates under
extremely high pressure: 1600 to 2300 PSI (11,033
to 15,859 kPa). Such repair will fail suddenly and
create unsafe conditions.
▪ Wear proper hand and face protection (e.g. face
shield) when searching for a high pressure hydraulic
leak. Use a piece of wood or cardboard as a back-
drop instead of hands. A high pressure concentrated
stream of hydraulic uid can pierce the skin. If this
should happen, seek immediate medical attention
as infection and toxic reaction could develop.
▪ Before applying hydraulic pressure to the system,
ensure all connections are tight and that lines, hos-
es, and couplings are not damaged.
Think Safety,
Work Safely!
▪ REVIEW ALL SAFETY INSTRUCTIONS with all opera-
tors before allowing them to operate the equipment.
Review instructions at least once each year.
▪ All shields and guards must be intact and in po-
sition and securely fastened before operating the
Windrow Inverter.
▪ Only use a tractor equipped with ROPS cab and seat
belt. Be careful when operating close to a road or
building, the machine can throw stones and other
objects during operation.
▪ Emphasize the importance of safety when working
around and operating the machine.
▪ Do NOT allow riders on any part of the equipment at
any time.
▪ Always keep hands, feet, and clothing away from
moving parts.
▪ Always lower the pickup to the ground when parking.
▪ Use a retainer or draw pin to secure the lifting lever
of the pickup before transporting equipment.
▪ Use safety tow chain at all times.
▪ NEVER attempt to unplug the machine when the trac-
tor is running and hydraulic system is pressurized.
▪ Keep hands, feet, and clothing away from the pickup
area when in operation to avoid entanglement haz-
ards. Do not open or remove shields or guards while
machine is running.
▪ Relieve all pressure from hydraulic lines before dis-
connecting them. Before applying pressure to the
system, make sure all connections are tight and
that hoses and lines have not been damaged.

Operation
Use with a tractor having a minimum of 50 HP (37 KW).
Tractor should have sufcient ground clearance for swath
to pass cleanly under it.
Level Inverter
When hooked up to the tractor the windrow inverter rear
frame should be parallel to the ground when measured
across upper cross tube and rear corner of moldboard
frame (A). If necessary level by changing the hitch tongue
mounting bolt locations in the main frame and/or by in-
verting the tongue in the main frame brackets (B).
The axles can also be pivoted up or down on the main
frame, in their slotted mounting holes (C).
Adjust tractor hitch if further adjustment is required.
Uneven Fields
Flotation Spring Adjustment
If pickup bounces too much due to uneven elds, release
the spring tension. First loosen off top nut (A), then turn
bottom nut (B) counter clockwise. This will put more weight
on the pickup and should help minimize the bouncing ac-
tion.
Pickup Finger Height
Gauge Wheel Adjustment
(Small Wheels)
Check pickup height when in eld position, crop should be
picked up cleanly without gouging the soil. Should adjust-
ment be required:
a. Raise or lower pickup, Figure 1.
b. Remove the nut on the bolt which holds the gauge
wheel on the pickup and place bolt in the desired lo-
cation, Figure 1. Tighten all nuts securely, ensuring
that the wheel turns freely.
Ensure both left and right hand wheels are set at the
same height.

Operation
Setting Pickup Speed
(Hydraulic Motor)
Lower the pickup to the ground. Engage the hydraulic le-
ver on the tractor, which controls the hydraulic motor on
the windrow inverter. The windrow inverter has a valve
that prevents accidentally turning the pickup backward.
The hydraulic system for operating the windrow inverter
consists of two basic components:
1. The hydraulic motor.
2. The adjustable ow control valve.
Adjustable Flow Control Valve
If your tractor has a:
CLOSED CENTRE TRACTOR HYDRAULIC SYSTEM WITH
ADJUSTABLE VALVE:
1. Set the windrow inverter ow control at maximum
setting of 10.
2. Engage the tractor hydraulic system lever.
3. Adjust the tractor ow control valve. If the oil surges
through the system, close the windrow inverter ow
control valve slowly until the surging stops.
4. Further windrow inverter valve adjustments may be
necessary to ensure smooth and complete pickup at
speed travelled.
If your tractor has an:
OPEN CENTRE HYDRAULIC SYSTEM WITHOUT AN AD-
JUSTABLE VALVE:
1. Set the windrow inverter ow control valve in the 0
position.
2. Engage the tractor hydraulic system lever.
3. Set the pickup speed with the windrow inverter ow
control valve to approximately 4 or 5.
4. Further adjustments may be necessary once you are
inverting to ensure smooth and complete pickup at
speed travelled.
Direction of Travel
Start inverting at the same location and direction as mow-
ing started, although the Matador Windrow Inverter will
generally pickup “against the grain” as well. Centre the
tractor and windrow inverter on the swath. Start gradu-
ally, and gear up smoothly, until you are operating at the
desired eld speed.
Adjust the hydraulic ow control on the tractor and/or the
windrow inverter to change the pickup speed as required.
Pickup speed should be sufcient to pickup crop cleanly.
Excessive leaf loss will occur if pickup speed is too fast.
In cereal crops or crops with an “in line” orientation, it will
be necessary to pick up the swath “head rst.”
The hydraulic pickup lift kit makes it easy to raise the
pickup over obstacles in the eld or to skip a swath which
does not need inverting.
With innite variety of crop and eld conditions, only op-
erator experience will indicate best driving, cornering and
adjustment techniques for maximizing the use of your
Matador Windrow Inverter.

chine you must:
□ Park machine on a solid level surface.
□ Disengage all power.
□ Put the tractor transmission in PARK or apply the
tractor parking brake.
□ Stop the tractor engine and remove key from the
ignition.
□ Look and listen. Make sure all moving parts have
stopped.
□ Install the cylinder safety stops, if applicable.
□ Block the inverter securely before working.
Checklist
CAUTION
Daily
□ Lubricate all items as required.
□ Remove all dirt and crop deposits from machine.
After Every 8 Hours Of Use
□ Grease gauge wheel bushings.
After The First 25 Hours Of Use
□ Check sprockets for set screw tightness.
After Every 100 Hours Of Use
□ Grease the sealed bearings on the pickup shaft
(two locations, front roll (two places) and rear roll
(four places).
At The Beginning Of Each Season
□ Review all safety instructions.
□ Carefully inspect all components for excessive wear
or hazardous conditions.
□ Lubricate the machine at all lubrication points to
force out any collected moisture.
□ Check drive chain for correct tension, replace if worn
or damaged.
□ Clean and repack or replace the wheel bearings, if
required.
□ Check tires for correct ination pressure.
□ Tighten bolts.
Setting Drive Chain Tension
1. Adjust tension with pickup pinned in raised position
(A).
2. Inspect and adjust through the access hole provided
in chain cover (B). The correct tension of the chain
should allow for approximately 1/2” (1.3 cm) of de-
ection when slight pressure is applied to the lon-
gest span of chain (C). If required move sprocket (D)
to increase or decrease tension on chain.
3. Check that the chain is not riding up on the sprocket
teeth (especially the large sprocket) as this would in-
dicate a worn out chain which requires replacement.
Regular lubrication with chain lubricant, proper ad-
justment, and replacement of worn chains will en-
sure proper function of the Matador and prolong the
life of the sprockets.

Metric Bolt Markings & Torque Values
Metric bolts are identied by the grade number stamped
on the head of the bolt or on the surface of metric nuts.
The higher the number, the greater the strength of the
bolt.

Maintenance
Note: For inch and metric bolts and nuts:
▪ These values are based on clean, dry threads. Reduce the value by 10% when a lubricant is used. Reduce
the value by 20% if new plated bolts are used.
▪ Bolts threaded into aluminum must have two diameters of thread engagement and may require 30% more
reduction in the torque.
