Introduction
The Macerator is designed to condition hay for a super
fast dry down while maintaining the maximum amount of
nutrients and color. The Macerator utilizes special steel
rolls, each running at a different speed allowing for a mea-
sured nicking of the stem for greater air exposure. The low
profi le, heavy duty pickup allows for rapid operation with
minimal leaf loss.
The roll system of the Macerator is designed to allow for the
right amount of maceration without cutting up the hay.
These operating and maintenance instructions have been
compiled from extensive fi 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 the beginning to end BE-
FORE operating your new Macerator 6620. Pay special
attention to the Safety section in this manual and the
safety cautions on your equipment. Should anyone else
operate this equipment be sure that they understand
ALL safety, operating, and maintenance information pre-
sented 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.
The photographs, illustrations, and data used in this man-
ual were current at the time of printing, but due to pos-
sible inline production changes, your machine can vary
slightly in detail. The Manufacturer reserves the right to
redesign and change the machine as necessary without
notifi cation.
WARNING
Some pictures in this manual show the machine with
shields removed to allow for a better view of the sub-
ject. The machine must never be operated with any of
the shields removed.
Congratulations, you have just purchased the new and improved AgLand Macerator 6620. To get the maximum
benefi t from your Macerator we suggest that you read this manual carefully.

Slow Moving Vehicle Emblem
The Slow Moving Vehicle (SMV) emblem
must be placed on the rear of the ma-
chine and be visible to traffi c approach-
ing the machine from the rear while
traveling on public roads. Keep the SMV
emblem clean and replace when dam-
aged or emblem materials have faded. The SMV should
only be displayed on the machine at road speeds less
than 25 MPH (40 km/h).
Safety
▪ The operator is responsible for complying with all
local regulations regarding transporting agricultural
equipment on public roads and highways.
▪ Ensure all lights and refl ectors, as required by local
law, are in place, intact, and clean before transport-
ing machine on public roads and highways.
▪ Connect electrical socket on machine wiring har-
ness to tractor receptacle.

Safety
Operating Safety
▪ Ensure that all components in the hydraulic system
are kept in good condition.
▪ Replace any worn, cut, abraded, fl attened, or
crimped hoses and/or metal lines.
▪ Do not attempt any poorly executed repairs to hy-
draulic lines, fi 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 fl uid can pierce the skin. If such
happens, seek immediate medical attention as in-
fection and toxic reaction could develop.
▪ Before applying hydraulic pressure to the system,
make sure all connections are tight and that lines,
hoses, 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
Macerator.
▪ Only use a tractor equipped with ROPS cab and seat
belt. Use caution 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 Macerator to the ground when
parking.
▪ Use transport lock pin and retainer to secure the
lift linkage of the Macerator 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.
Hydraulic Safety
▪ Make sure all hoses and bellows are kept in good
condition and are clean.
▪ Replace any damaged lines or bellows.
▪ Do not exceed 120 PSI (827 kPa) air pressure in
tank and 100 PSI (689 kPa) in air bags.

1. Raise the Macerator using the hydraulics.
2. Turn crank (A) clockwise to widen the gap or counter-
clockwise to narrow the gap. 1/2 turn = .02” (0.5
mm). For a better fi ne tune, adjust bolt (D).
3. Ensure to set the gap exactly the same on both sides,
using a gauge.
4. Put crank lock (B) in place and secure with pin (C).
5. To ensure that the rolls do not touch, the safety stop
is set by the factory at 1/32” or .8 mm.
6. If the safety stop (E) needs adjusting put the travel
pin (F) in place while unit is raised.
7. Adjust the safety stop bolt (E) as needed. Ensure the
rolls do not touch during operation.
8. Repeat steps 1–7 to fi ne tune if necessary.
Field Set Up
Use with a tractor having a minimum of 80 HP (60 kW).
Tractor should have suffi cient ground clearance for
swath to pass cleanly under it.
PTO Speed
Unless otherwise specifi ed, units are shipped with 1000
PTO speed. Units with 540 RPM PTO are also available.
Contact your dealer for more information.
The PTO should be run at approximately 1000 RPM. The
front rubber rolls run at 645 RPM and the bottom steel
roll runs at 1514 RPM at a tractor PTO speed of 1000.
The upper steel roll runs at 1372 RPM at 1000 tractor
PTO speed.
Pickup Height & Adjustment
The Macerator 6620 pickup should be adjusted so that
it will cleanly pick up all material off of the fi eld without
gouging the soil. The height may need resetting in order
to arrive at the best working height.
1. If the pickup is too low to the ground use the tractor
hydraulic cylinder control to raise the pickup.
2. Remove pin (A) and slide adjuster bar (B) to desired
height. Pushing bar in raises machine, and pulling
the bar out lowers the machine.
3. Reinsert pin and lock in place.
Gap Gap
Steel Roll Adjustment
For best results adjust the Macerator 6620 for your specif-
ic fi eld conditions. The smaller the gap between the steel
serrated rolls, the more aggressive the maceration of the
hay will be. Both the space between the rolls and the air
pressure need to be adjusted for maximum effi ciency.
