tices protect you and the people around you. Make these
practices a working part of your safety program. Familiar-
ize EVERYONE who operates this equipment with the rec-
ommended operating and maintenance procedures and
ensure they follow all the safety precautions.You can pre-
vent most accidents. Do not risk injury or death by ignoring
good safety practices.
• Lockwood 472H owners must review operating instruc-
tions to operators or employees before allowing them
to operate the machine, and at least annually thereaf-
ter per OSHA (Occupational Safety and Health Admin-
istration) regulation 1928.57.
• The most important safety device on this equipment is
a SAFE operator. The operator is responsible to read
and understand ALL Safety and Operating instructions
in the manual and to follow them. You can avoid most

2.1 GENERAL SAFETY
2.2 OPERATING SAFETY
1. Install and secure all guards and shields before start-
ing or operating.
2. Clear the area of bystanders, especially small children,
before starting the tractor.
3. Place all machine controls in neutral before starting
the tractor.
4. Keep hands, feet, hair and clothing away from all mov-
ing and/or rotating parts.
5. Keep all hydraulic lines, fittings, and couplers tight and
free of leaks before and during use.
6. Clean reflectors and lights before transporting.
7. Review safety related items annually with all personnel
who will operate or maintain the harvester.
8. Be careful when operating on uneven terrain, or near
ditches to avoid the potential of overturning the ma-
chine.
9. Use only recommended tractor sizes with proper weight
and equipment for operating the machine.
10. Never stand between the tractor and the machine when
the tractor backs up for hookup.
11. Use the correct size hitch pin to prevent unhitching.
12. When backing up the machine, all persons must stand
away from the back of the unit due to the operator’s
impaired vision.
13. Be careful during field and transport operation not to
contact trees, power poles, and electrical lines with
the machine’s row marker. Electrocution can occur
without direct contact.
14. Shut the tractor off when connecting or disconnecting
the machine hydraulics.
2.3 MAINTENANCE SAFETY
1. Follow ALL the operating, maintenance, and safety in-
formation in the manual.
2. Support the machine with blocks or safety stands when
changing tires or working beneath it.
3. Follow good shop practices:
•Keep service area clean

Page 6 472H Potato Harvester Owner Operator’s Manual
2.4 HYDRAULIC SAFETY
1. Always place all tractor hydraulic controls in neutral
before disconnecting from tractor or working on the
hydraulic system.
2. Keep all components in the hydraulic system in good,
clean condition.
3. Relieve pressure before working on the hydraulic sys-
tem.
4. Replace any worn, cut, abraded, flattened or crimped
hoses.
5. Do not attempt any makeshift repairs to the hydraulic
fittings or hoses by using tape, clamps or cements.
The hydraulic system operates under extremely high-
pressure. Such repairs will fail suddenly and create a
hazardous and unsafe condi-
tion.
6. Wear proper hand and eye pro-
tection when searching for a
high-pressure hydraulic leak.
Use a piece of wood or card-
board as a backstop instead of
hands to isolate and identify a
leak.
7. If injured by a concentrated
high-pressure stream of hydrau-
lic fluid, seek medical attention
immediately. Serious infection
or toxic reaction can develop from hydraulic fluid pierc-
ing the skin surface.
8. Before applying hydraulic pressure to the system,
tighten all components and check for damaged lines,
hoses, and couplings.

shafts.
2. Be extremely careful when working around PTO
shafts, drivelines, or other rotating shafts.
3. Do not remove or
modify protective
shields or guards.
4. Do not step
across a PTO or driv-
eline or use it as a
step.
5. Keep guards and
shields in place at all
times while operating.
6. Replace all damaged or missing parts or shields with
the correct original manufacturer’s parts.
7. Grease, clean, and maintain PTO components ac-
cording to original manufacturer’s specifications and
information in this manual.
8. Operator must wear fairly tight clothing. Never wear
loose-fitting jackets, shirts, or pants when working
around the drive shafts. Tie long hair back or put un-
der a cap.
9. Keep hydraulic hoses, electric cords, chains, and
other items from contacting the drive shafts.
10. Do not clean, lu-
bricate, or adjust the
drive shafts with the
PTO engaged and the
tractor running.
