SAFETY RULES

A TTENTION! BECOME ALERT! YOUR SAFETY IS INVOL VED!

Safety is a primary concern in the design and manufacture of our products. Unfortunately , our efforts to provide
safe equipment can be erased by an operator’s single careless act. In addition, hazard control and accident
prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in
the operation, transport, maintenance and storage of equipment.

Make certain that the operator(s), prior to operating is instructed in safe and proper use and reviews and
understands the manual(s) pertaining to this machine.

Read this manual before you operate this machine. If you do not understand any part of this manual, or need
more information, contact the manufacturer or your authorized dealer .

SAFETY

Understand that your safety and the safety of other persons is measured by how you service, and operate this
machine. Know the positions and functions of all controls before you try to operate them. Make sure to check
all controls in a safe area before starting your work.

The safety information given in this manual does not replace safety codes, federal, state or local laws. Make
certain your machine has the proper equipment as designated by local laws and regulations.

A frequent cause of personal injury or death is from persons falling of f equipment and being run over. Do not
permit persons to ride on this machine.

Travel speeds should be such that complete control and machine stability is maintained at all times. Where
possible, avoid operating near ditches, embankments and holes. Reduce speed when turning, crossing slopes
and rough, slick or muddy surfaces.

Collision of high speed road traffic and slow moving machines can cause personal injury or death. On roads,
use flasher lights according to local laws. Keep slow-moving-vehicle emblem visible. Pull over to let faster
traffic pass.

Never adjust, service, clean, or lubricate running gear until all power is shut off.
Keep all safety shields in place.
Keep hands, feet, hair and clothing away from moving parts while unit is in operation.
Make sure that everyone is clear of equipment before applying power or moving the machine.
Make sure that the running gear is fastened securely to the tractor by using the proper hitch pin, clip and safety

chains.
Never overload the running gear. Overloading the running gear is dangerous and can cause extensive damage.

Do NOT exceed load limit or speeds in excess of 20 MPH. Rims, hubs and bearings are designed for heavy
loads at slow speeds. Also be sure slow moving vehicle emblem is attached to rear of wagon.

Before unhooking the running gear from the towing unit, be sure to properly block the wheels to prevent the cart
from moving.

SET-UP INSTRUCTIONS FOR RUNNING GEAR

IMPORTANT: Set-up work to be performed by qualified servicemen only.

Mount tires on the wheels and inflate per the tire manufacturer’s recommendations and instructions.

1)
Mount the wheels to the hubs and tighten the hub nuts to 80 ft. lb. torque. Check the hub nuts after

2)
the first hour of operation, then every 10 hours of operation for the first 40 hours of use. These nuts
must be kept tight at all times. Wheels that are improperly installed on the running gear , resulting in
product failure, will nullify the warranty and shift the burden of liability to the owner/operator of the
equipment.

Slide the coupling pole into the front and back assemblies, slipping the collar in the back assembly .

3)
Sp acing of the coupling pole (approximate distance between holes on the coupling pole) should be 21
1/2”. Distance from center of axle to center of axle is approximately 89”.

Attach the standards (box attachment brackets) to the running gear, unless a rocking bolster is

4)
used.

Fasten the tongue to the front assembly using the tongue bolt (remove paint from the bolt before

5)
attaching) and jam nut. Attach the tongue spring to the bracket on the tongue and hitch assembly.
Check underneath the tongue and make sure that the safety catch (7/8” x 2 1/4” bolt w/spacer) is
secure.

Make sure to properly attach the gravity box (or other equipment) to the running gear. Bolt all four

6)
corners of the gravity box runners to the running gear. (If the box is used in rough terrain and it is not
equipped with a rocking bolster, bolt a minimum of two corners and chain (or cable) the remaining
corners to allow more box flexibility).

OPERATING INSTRUCTION / MAINTENANCE

BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING EQUIPMENT .

Before equipment is put into service:
Has this manual and the operator’s manual on the gravity box been read and clearly understood by the

operator(s) of this machine?
Have all braces, bolts, nuts, lug bolts, and lug nuts been checked to ensure that they are properly fastened?
Is the running gear properly fastened to the tractor? Use a good quality hitch pin with clip and safety chain.

SAFETY CHAIN USER INSTRUCTIONS

a) Secure the safety chain by looping it around the tongue support located on the underside of the outer
tongue. Extend the chain through the support located on the underside of the inner tongue and connect to
the towing machine’s attaching bar .
b) Be sure to run the safety chain through the support on the underside of the inner tongue. This will
provide an intermediate support for the safety chain.
c) Do Not allow more slack than necessary for articulation (max. 9 inches).
d) Do Not use any intermediate support as the attaching point.
e) Store the safety chain by securing it around the tongue support s.
f) Replace the safety chain if one or more links or end fittings are broken, stretched or otherwise damaged
or deformed.

Have all danger, warning, caution and import ant signs on the equipment been read and clearly understood? If
employees or others use or are near this equipment, make sure that they also have read and understood all
danger, warning caution and important signs on the equipment and have also read the operator’s manual.

750-16 OWNER’S MANUAL

Have the wheel bearings been inspected? Repack with grease if needed. Grease both the tongue bolt and the
hitch bolt.

Do not exceed the load limit of the unit.

SYSTEM REQUIREMENTS:

Tow Loads Safely

Stopping distance increases with speed and weight of towed loads, and on slopes. Towed loads without
brakes that are too heavy for the tractor or are towed too fast can cause loss of control. Consider the total
weight of the equipment and its load.

Observe these recommended maximum road speeds, or local speed limits which may be lower:

If towed equipment does not have brakes, do not travel more than 32 km/h (20 mph) and do not tow
loads more than 1.5 times the tractor weight.

Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing loads
under adverse surface conditions, when turning, and on inclines.

IMPORT ANT:

Keep the tires properly inflated. Both under inflation and over inflation can greatly reduce tire life.
Inspect bracing and welds and repair if needed. Failure to repair could cause extensive damage and greatly

reduce the life of the unit.
Inspect tie rods and replace the bronze bushings in the steering assembly when needed.
Repack the bearings in the hub assemblies once a year or as needed. Use a good quality bearing lubricant

such as Bearing Gard MK1 or equivalent. NOTE: Grease zerks on hub caps are for between scheduled
service lubrication.
