2.0 SAFETY
2.1 Recognizing Safety Informaon in Manual
Figure 2 is the safety-alert symbol. When you see this symbol on your ma-
chine 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 Harvester Safety
You are responsible for the safe operaon and maintenance of your Amity beet harvester. You and any-
one else, who will operate, maintain, or work around the harvester should be familiar with the oper-
a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.
Harvester owners must give operang instrucons annually to operators or employees before allowing
them to operate the harvester per OSHA regulaon 1928.57.
The most important safety device on this equipment is a safe operator. It is the operator’s responsibil-
ity to read and follow all safety and operang instrucons in the manual. All accidents can be avoided.
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 and/or
safety and could alter the life and warranty of the product.
The following list is a set of safety guide lines to adhere to:
1. Read and understand the Operator’s Manual and all safety signs before operang, maintaining, or
adjusng the harvester.
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.

6. 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.
7. Review safety related items with all operators annually.
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 mainte-
nance, adjustment, and operaon of the harvester.
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.
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 harvester.
6. Make sure that all guards and shields are properly installed and secured before operang the har-
vester.
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 harvester or tractor during eld operaon or transport.
10. Never operate the harvester inside a closed building.
11. Stay away from overhead obstrucons and power lines during set up and operaon. Electrocuon
can occur without direct contact.
Figure 3: Maintenance and Operaon Safety Symbols

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 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.
Figure 5: Hydraulic Safety Symbols
2.5 Transport Safety
1. Read and understand all informaon in the Operator’s Manual regarding procedures and safety
when operang the harvester 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 harvester during either eld operaon or travel.
4. Aach to the tractor using only a drawbar pin with provisions for a mechanical retainer.
5. Always aach a safety chain.
6. Always use hazard warning ashers when transporng unless prohibited by law.

11
7. Always lower elevator boom when transporng harvester.
8. Stay away from overhead obstrucons such as power lines.
9. For max transport speed on smooth roads see secon 3.2.
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, removed, become illegible, or parts are replaced
without decals, new decals must be applied. New decals are available from your authorized dealer.

4.0 PREPARATION
4.1 Tractor Preparaon
4.1.1 Adjusng the Drawbar: The tractor
drawbar must be set within the given
range to maintain the integrity of the drive
system. The range is shown in Figure 6.
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 Ta-
ble 2: Tire Size and Pressure on page 7 for more infor-
maon. Figure 7 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 con-
tact 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 the spacing
matches the spacing of the planted crop as shown
in Figure 9.
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 Operang the Harvester secon
6.9.1 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 and oil type. “Full Cold Line” on
the decal should be at the dimension shown in Figure
10.
CAUTION: Valves (1 & 2) must be open prior to
engaging the PTO, or system failure will occur. Valves in
Figure 9 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 12.
When a 12V switched source is not available,
an alternave way to aach the control box is
shown in Figure 13.
NOTE: Figure 12 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 13, 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 14.
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
requirements.
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 2- 5/8 in. bolts and nuts.
5. Slide and lock the shield into place.
4.2.8 Raising Boom: Once in the eld, follow these steps 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 elevated posion.

5.0 ATTACHING AND DETACHING
5.1 Aaching Hydraulic and Electrical Systems
Harvesters are available with ISO couplers or metric adapters. If
the hydraulic aachments on your harvester do not t the tractor,
contact your Amity dealer.
CAUTION: To avoid injury from escaping uid under pressure,
relieve the pressure in the system before disconnecng or con-
necng hydraulic or other lines. Tighten all connecons before ap-
plying pressure.
1. Connect all hydraulic lines to tractor as shown in Figure 18.
2. Connect the harvester warning light harness to the tractor.
Make sure the harvester warning lights operate with the trac-
tor warning lights and turn signals.
3. Connect the control monitor or switchbox to the harness routed into the tractor cab.
5.2 Aaching Harvester to Tractor Drawbar
1. Adjust the tractor drawbar (see Tractor Prepara-
on, secon 4.1.1)
2. Remove the tractor hitch pin.
3. Install required bushings into pull plate.
4. Adjust the hitch height.
5. Shi to park, shut o the engine, and remove the
ignion key before geng out of tractor.
6. Line up the pull plate with the drawbar.
7. Place hardened washer (A) between the drawbar
and pull plate, and install shims as necessary (B).
