1.0 INTRODUCTION
1.1 General Informaon
Read this manual carefully to learn how to operate and service your machine correctly. Failure to read
this manual can result in personal injury or equipment damage.
This manual is a permanent part of your machine and should remain with the machine when you sell it.
Measurements in this manual are given in both customary U.S. units and metric equivalents. Use only
correct replacement parts and fasteners. Metric and inch fasteners require appropriate tools to install.
NOTE: Right- and le-hand sides are determined by facing in the direcon the implement will travel
when moving forward.
1.2 Serial Number
Record the serial number, model number, and model year of your harvester to help trace the machine
in the event that it is stolen. Your dealer also needs these numbers for all warranty claims and for
when you order parts.
The harvester serial number is found on the serial number plate, which is located on the front of the
machine as shown in Figure 1-1.
Record your serial number, model number, and model year in the space provided below.

2.0 SAFETY
2.1 Recognizing Safety Informaon in Manual
Figure 2-1 is the safety-alert symbol. When you see this symbol on your
machine or in this manual, be alert to the potenal for personal injury.
Follow recommended precauons and safe operang pracces.
2.2 General Safety
You are responsible for the safe operaon and maintenance of your Amity implement. You and anyone
else who will operate, maintain, or work around the machine should be familiar with the operang and
maintenance procedures and safety informaon in this manual.
Safety pracces protect you and the people around you, so make them a working part of your safety
program.
Equipment owners must give operang instrucons annually to operators or employees before allow-
ing them to operate the machine, per OSHA regulaon 1928.57.
The most important element of safety for this equipment is a safe operator. It is the operator’s respon-
sibility to read and follow all safety and operang instrucons in the manual. All accidents can be avoid-
ed.
A person who has not read and understood all operang and safety instrucons is not qualied to op-
erate the machine. An untrained operator exposes himself and bystanders to serious injury or death.
Do not modify the equipment in any way. Unauthorized modicaon may impair the funcon or safety,
or both, and could alter the life and warranty of the product.
The following list is a set of safety guidelines to adhere to:
1. Read and understand the Operator’s Manual and all safety signs before operang, maintaining, or
adjusng the machine.
2. Install and properly secure all shields and guards before operang.
3. Have a rst-aid kit available and know how to use it.
4. Have a re exnguisher available and know how to use it.
5. Clear the area of people and remove foreign objects from the machine before starng and oper-
ang.
6. Shi to park, disengage PTO, lower machine to ground, relieve hydraulic pressure, stop engine, re-
move ignion key, and wait for all moving parts to stop before servicing, adjusng, repairing, or dis-
connecng.
Figure 2-1: Safety-Alert Symbol

2-2
7. Annually review safety guidelines with all operators.
8. Wear suitable ear protecon for prolonged exposure to excessive noise.
Think SAFETY! Work SAFELY!
2.3 Maintenance and Operang Safety
1. Read and understand all informaon contained in the Operator’s Manual regarding maintenance,
adjustment, and operaon of the machine.
2. Shi to park, disengage PTO, lower machine to ground, relieve hydraulic pressure, stop engine,
remove ignion key, and wait for all moving parts to stop before servicing, adjusng, repairing, or
disconnecng the machine.
3. Keep hands, feet, clothing, and hair away from all moving and/or rotang parts.
4. Ensure that all tractor controls are in neutral before starng.
5. Never wear ill-ng, baggy, or frayed clothing when working on or around the machine.
6. Make sure that all guards and shields are properly installed and secured before operang the ma-
chine.
7. Clear the area of all bystanders, especially children, when carrying out any maintenance or making
adjustments on the systems or components.
8. Place stands or blocks under the frame before working beneath the machine.
9. Do not allow riders on the implement or tractor during eld operaon or transport.
10. Never operate the machine inside a closed building.
11. Stay away from overhead obstrucons and power lines during setup and operaon. Electrocuon
can occur without direct contact.

2-3
2.4 Hydraulic Safety
1. Always place all tractor hydraulic controls in neutral before dismounng.
2. Make sure that all components in the hydraulic system are kept in good condion and are clean
and ght.
3. Replace any worn, cut, abraded, aened or crimped hoses and metal lines.
4. Do not aempt any makeshi repairs to the hydraulic lines, ngs, or hoses by using tape,
clamps, or cements. The hydraulic system operates under extremely high pressure. Such repairs
may fail suddenly, creang a hazardous and unsafe condion.
5. Wear proper hand and eye protecon when searching for a high-pressure hydraulic leak. Use a
piece of wood or cardboard as a backstop instead of hands to isolate and idenfy a leak.
6. If injured by a concentrated high pressure stream of hydraulic uid, seek medical aenon imme-
diately. Serious infecon or toxic reacon can develop from hydraulic uid piercing the skin’s sur-
face.
7. Before applying pressure to the system, make sure all components are ght and that lines, hoses,
and couplings are not damaged.
8. On self-contained hydraulic systems, make sure that shut o valves are in open posion before
engaging PTO.
2.5 Transport Safety
1. Read and understand all informaon in the Operator’s Manual regarding procedures and safety
when operang the machine in the eld or on the road.
2. Make sure the Slow Moving Vehicle (SMV) emblem and required lights and reectors are in place,
clean, and can be seen clearly by all overtaking and oncoming trac.
3. Do not allow riders on any part of the machine during either eld operaon or travel.
4. Aach the machine to the tractor using only a drawbar pin with provisions for a mechanical re-
tainer.
5. Always aach a safety chain.
6. Always use hazard warning ashers when transporng unless prohibited by law.
7. Always move all parts of the machine to transport posion when travelling on a road.
8. Stay away from overhead obstrucons, such as power lines.
9. For max transport speed on smooth roads, see secon 3.3.

2.6 Safety Decals
The types of decals on the equipment are shown in the illustraon below. Proper safety requires that
you familiarize yourself with the various safety decals, the type of warning, and the area, or parcular
funcon related to that area, that requires your safety awareness.
REMEMBER: If safety decals have been damaged or removed, become illegible, or parts are replaced
without decals, then new decals must be applied. New decals are available from your authorized deal-
er.

3.4 Hydraulic Flow Rates
Each hydraulic circuit for the harvester has a designated ow rate; approximate values are listed in
the table below.
NOTE: Values listed are a good starng point; however, ow rates should be ne-tuned to allow the
smallest ow rate possible while sll providing enough power to run harvester properly.

4.0 PREPARATION
4.1 Tractor Preparaon
4.1.1 Adjusng the Drawbar: It is recommended
that the tractor drawbar be set to the shortest
posion and be within the given range (in accord-
ance with ANSI/ASABE AD6489-3) to maintain the
integrity of the drive system. Dimensions are
shown in Figure 4-1.
IMPORTANT: Ensure the driveline remains within operang range under all condions.
4.1.2 Tire Spacing and Inaon: Tires should be inat-
ed to the manufacturer’s specicaon. See Secon 3.3,
Tracon, for more informaon. Figure 4-2 shows the
appropriate re spacing.
A = 4 * B
B = Row Spacing
C = Tire Width; must be as narrow as possible.
IMPORTANT: Tires must be narrow enough not to contact beets when driving down rows while sll
providing enough tracon to pull the harvester.
NOTE: The Front res must be aligned with the rear res.
4.1.3 Three-Point Hitch Posion: Three-point hitches cannot be
connected to the hitch when using an Amity beet harvester. It
must be fully raised or removed.
NOTE: Amity recommends removing three-point hitches.
CAUTION: Ensure the receiver and drawbar support arms clear the PTO driveline under all condi-
ons.

4.2 Harvester Preparaon
4.2.1 Lier Strut Spacing: Verify that the spacing
matches the spacing of the planted crop as shown
in Figure 4-4.
A = B/2 Center of frame to center of strut
B = Row spacing
C = Space appropriate for size of beets. (This
space is the pinch point.)
NOTE: Refer to Secon 6.9, Operang the Har-
vester, for pinch point spacing guidelines.
4.2.2 Hydraulic Tank Oil Level and Valve Posion: Re-
fer to secon 11.0, Lubricaon and Maintenance, for
the service schedule, oil type, and lter replacement
info. “Full Cold Line” on the decal should be at the di-
mension shown in Figure 4-5.
CAUTION: Valves (1 & 2) must be open prior to
engaging the PTO or system failure will occur. Valves in
Figure 4-5 are shown in the open posion.
4.2.3 Scrub Control Box Wiring and Locaon: The scrub control box must
be correctly wired and securely fastened in the tractor cab. The correct
wiring is as follows:
White or Red wire: 12V Posive
Black wire: 12V Negave
NOTE: Locate the scrub box in a safe and secure locaon away from poten-
al liquid spills.

The preferred method for aaching the con-
trol box to the tractor is to use a 12V switched
source as shown in Figure 4-7.
When a 12V switched source is not available,
an alternave way to aach the control box is
shown in Figure 4-8.
NOTE: Figure 4-7 shows the preferred method of
aachment and should be used if at all possible.
CAUTION: When using the connecon
method shown in Figure 4-8, the control must be
disconnected when not in use.
Aer wiring the control box to the tractor, the
harness on the harvester must be wired to the
actuator switch as shown in Figure 4-9.
4.2.4 Shield Placement: Before starng, be sure to secure the
shields in operang posion (closed posion).
4.2.5 Gearbox Oil Level: Check all gearbox oil levels before operang.
Refer to secon 11.0, Lubricaon and Maintenance, for oil type and ll
level informaon.

4.2.6 Greasing: Refer to secon 11.0, Lubricaon and Maintenance, for grease type and frequency re-
quirements.
IMPORTANT: Use only hand-held grease guns. Air-powered grease guns can damage your seals. Over
greasing may also damage bearing seals. If damage due to over greasing occurs, replace the damaged
seals immediately.
4.2.7 Aaching PTO to Harvester:
1. Remove the spring pin on the shield.
2. Slide the shield forward.
3. Connect the PTO to the spline sha.
4. Lock the PTO in place using two 5/8 inch bolts and nuts.
5. Slide and lock the shield into place.
4.2.8 Raising Boom: Once in the eld, follow the steps below before liing beets.
1. Raise the boom.
2. Set the boom to the desired height by locking pins to one of the 4 holes on the support struts.
3. Lower the boom onto the pins to relieve hydraulic pressure on the hydraulic cylinders.
4. Move the selector valve to the elevated posi-
on.
