SAFETY RULES

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

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, judgment, 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. Also make certain that the operator(s) reviews and
understands the operator’s manual of the grain cart and the tractor.

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 are measured by how you service, and
operate this machine.

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.

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. If a ditch must be crossed, do so
at an angle. Avoid sharp turns to maximize the stability of the road. Reduce speed when turning,
crossing slopes and rough, slick or muddy surfaces. Avoid running over hard objects protruding above
the ground surface, if possible. Damage to the understructure or load may result. If the object is
unavoidable, reduce speed.

Never adjust, service, clean, or lubricate track system until all power is shut off. Keep all safety shields in
place. Support equipment and attachments properly when working beneath them. Do not depend on
hydraulic cylinders to hold them up. An attachment can fail if a control is moved, or if a hydraulic line
breaks. Wear protective glasses when servicing equipment.

SET-UP INSTRUCTIONS

Your Storm Tracker Track System is shipped partially assembled with a Left and Right Side Complete
Track and Belt Unit and a center Cross Beam Axle. IMPORTANT: Be sure the air-bag located on each
Complete Belt Unit is positioned toward the front of the track assembly. To install partially assembled
items, follow the instructions below:

1) Insert the 6” x 27 3/4” Shaft (#50) into each
end of the Cross Beam Axle (#51) and secure
using two 1” x 9” Grade 8 Bolts (#52) and two

INSTALLING AN ELECTRONIC WEIGH SCALE SYSTEM

Installing the Weigh Bars to the Cross Beam Axle

1. Before separating the grain cart from the track system, be sure the grain cart hitch is lowered to the
ground with a forklift.

2. Position the forks of the forklift underneath the A-frame tubing directly behind the rear legs of the grain
cart. For greater stability, be sure the forks are spread out as wide as possible. The grain cart is secured
to the cross beam axle of the track system with eight 1” x 3” grade 5 bolts and lock nuts. Remove the 1” x
3” grade 5 bolts and slightly lift the grain cart off the cross beam axle. IMPORTANT: Be sure the grain

cart and forklift are secured and free from falling to prevent serious injury or death. Always
maintain a safe working environment. Never place yourself between the grain cart and the track
system.

3. There are four weigh bar sleeves located on the track Cross Beam Axle (two at each end, one on the
front and one on the rear of the axle). Slide one 2 7/8” weigh bar weldment into each sleeve and secure
using one 3/4” x 6” grade 5 bolt with lock nut. NOTE: Be sure the hitch weigh bar is secured in the

UP POSITION as indicated by the decal on the weigh bar. The weigh bar will not read correctly
unless the sensor is positioned correctly.

4. Attach the Track Mounting Plate to the opposite end of the each weigh bar using one 1” x 4 1/2” grade
5 bolt and lock nut.

5. Slowly lower the grain cart until the attaching plate on the grain cart A-frame meets the track mounting
plates on each of the four weigh bars and the holes are aligned. Secure the track mounting plates to the
grain cart using sixteen 1” x 3” grade 5 bolts and lock nuts.

Attaching the Hitch Weigh Bar

6. Remove the 1” x 4 1/2” grade 5 bolt and lock nut
that attaches the rear collar of the hitch assembly to
the 2 1/2” x 13 1/4” shaft. Remove the hitch and shaft
assembly from the front of the grain cart.

7. Remove the eight 3/4” x 3” grade 8 bolts from the
Hitch Spool Plate Support located on the front of the
A-Frame. Bolt the 2 7/8” Weigh Bar Weldment to the
threaded holes located on the rear of the A-Frame
using four 3/4” x 3” grade 8 bolts.

9. Reuse the 1” x 5 1/2” grade 5 bolt and locknut to
secure the hitch weigh bar to the 2 7/8” hitch. Before
installing the Hitch Weigh Bar, feed the wire through
the left side of the A-Frame tubing and exit the frame
through the grommet located directly behind the front
leg of the grain cart. Slide the rear of the Hitch Weigh
Bar through the 2 7/8” Weigh Bar Weldment and
secure using the 1” x 4 1/2” grade 5 bolt and locknut.

NOTE: Be sure the hitch weigh bar is secured in
the UP POSITION as indicated by the decal on the
weigh bar. The weigh bar will not read correctly
unless the sensor is positioned correctly.

Mounting the Junction Box

10. Using the Junction Box as a template, mark and drill
holes on the inside face of the front left side leg of the
grain cart. The Junction Box should be positioned
approximately 23” above the tubing of the A-Frame.
After the holes have been drilled, secure the Junction
Box to the inside of the front leg of the grain cart using
four #10 bolts and nuts.

11. Remove the cover from the Junction Box. Insert the
Hitch Weigh Bar wire through the center port and
connect to the center terminal of the Junction Box by
matching the colored wires. Repeat for the two left and
two right side weigh bars located on the track Cross
Beam Axle.

12. Connect the J-Box cable between the center
terminal and the indicator located on the front of the
grain cart leg. Replace the cover on the Junction Box.

Mounting the Indicator

13. A mounting bracket is included to mount the
indicator to the front leg of the grain cart. Using the
mounting bracket as a template, mark and drill 7/16”
holes on the front leg of the grain cart approximately 33”
above the A-Frame.

14. Secure the mounting bracket to the front leg using
two 3/8” x 1” flange bolts and nuts. Slide the Indicator
across the top of the mounting bracket and secure using
two #10 bolts and nuts. (NOTE: An extension cord
between the J-Box cable and the Indicator is available to
mount the indicator in the tractor cab.) Connect the J­Box cable to the port on the bottom of the indicator.

Mounting the Battery Box

15. Using the Battery Box as a template, mark and drill
two 7/16” holes on the inside of the front leg
approximately 16” above the A-Frame. Secure the
Battery Box to the leg of the grain cart using two 3/8” x
1” flange bolts and nuts. (12 Volt Lawn and Garden
Battery is not included.)

Connecting the Power Cord

16. To connect the Power Cord to the Indicator Box, attach the screw plug end of the power cord into the
power port of the Indicator Box. To connect to the battery, secure the red wire of the power cord to the
positive terminal of the battery and the black wire to the negative terminal. Be sure any additional wires
provided by the power cord are properly stored and secured.

OPERATING INSTRUCTIONS

IMPORTANT: To maximize the life of your track system, it is recommended that wide turns be
consistently made whenever possible. Turning a circle that is THREE TIMES the overall length of the
tractor and track unit will reduce premature wear on the belt and undercarriage.

LUBRICATION SERVICE SCHEDULE

IMPORTANT: Your Track System has grease fittings at all critical points. These should be serviced
before the track is put into operation. BE SURE THAT ALL POWER IS SHUT OFF BEFORE
SERVICING THE TRACK SYSTEM.

The grease points shown should be lubricated daily before use. (Note: Grease points A, B and C are
typical each side.)

The mid-roller bogies located on the inside of the track system (the opposite side of Grease Point B
shown above) also need to be greased daily before use. For easy access, a grease hose has been
added to these points and connected to the outside of the Cover Plate Assembly (Part # 47).

Multipurpose Lithium Grease is recommended for idler and midroller bearing lubrication.

ROUTINE MAINTENANCE

WARNING: When Servicing The Track System, Be Certain All Power To Grain Cart Is Shut Off.

Repack the wheel bearings at least once a year. Use Bearing Gard MK1 or equivalent lubricant. Also
check the seal for wear and replace if necessary.

Check the track system periodically for cracks in welds and for other structural damage. Have cracked
welds fixed immediately. Failure to do so could result in extensive damage to the track system and grain
cart and greatly reduce the life of the equipment.

Lubricate the track system according to the Lubrication Service Schedule.

Make sure that all guards and shields are in place before operating the track system.

Check the pressure in the air spring after every 100 hours of operation and at the beginning of each
season. The correct air pressure is 100 psi.

Check the wheel hubs and make sure the nuts are torqued to 350 ft. lbs. Check the hub nuts after
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 and maintained, resulting in
failure, will nullify the warranty and shift the burden of liability to the owner/operator of the equipment.

TROUBLESHOOTING

AIR BAG REPLACEMENT

If replacement of the track tension air springs become necessary, the following steps must be performed:

1. Slowly remove the air pressure from the rubber bladder.

2. Remove bolts that hold air spring in place and remove air spring.

3. Install new air spring between pressure plates. Be careful not to damage brass air fitting on top of air

spring.

4. Install and tighten bolts on bottom side of air bag using blue lock-tight. DO NOT OVERTIGHTEN as
cracking of plastic base will occur. Bolt torque should be 20-30 ft.-lbs.

5. Slowly fill air bag with compressed air to the recommended pressure in owner’s manual. Stand clear
of any moving parts while filling up air springs. Sudden movement can occur.

TRACK ALIGNMENT

The rubber tracks are held in proper alignment by the front alignment weldment. Track alignment is set at
the factory but may need further adjustment. Rubber tracks require a run in period to seat properly. More
adjustment may be necessary for the first week or two. It is normal for tracks to favor one side or the
other depending on ground condition, contour and carrying weight. If after a suitable time period you feel
the track is misaligned, follow the instructions below.

STEP 1 - Loosen the 3/4” vertical bolt
with 1 1/8” wrench

STEP 2 - Loosen the 1/2” nuts (one
each side) on set screws with 3/4”
wrench

STEP 3 – Correct alignment by
adjusting the 1/2” set screws on each
side of the Tracking Arm using a 1/4”
hex key wrench. If the center guide
lugs are showing wear on one side,
adjust the tracking arm in the direction
of that side. Back the set screw out on
the wear side no more than one full
turn at a time before checking (Step 4).
(Final adjustment may be only 1/8 of a
turn of the set screw.) Force the
tracking arm to that set screw with the
opposite set screw. Tighten both set
screws against the side of the Tracking
Arm. Tighten both 1/2” nuts and the
3/4” vertical bolt.

STEP 4 – Check the Alignment. Pull
the track a short, straight distance.
Touch each side of Guide Lugs. If one
side is warm, then the guide lugs are
still rubbing against the End Idler
Wheel and further adjustment of the
Tracking Arm toward the warm side is
needed. Repeat Alignment Procedure
until Guide Lugs are no longer warm.

When the Guide Lugs on the Rubber
Belt clear both End Idlers Wheels, the
belt is properly aligned.

BELT INSPECTION

The rubber track is composed of several layers of cable, similar to the cables used in automotive tires.
The most important set of cables are located about 8 mm (0.3 in.) beneath the inside surface of the track.
This set of cables, called zero degree cables, withstands track tension. Other cables, called breaker
cables, are located between the zero degree cables and the outside surface of the track. These are laid
in various angles to provide lateral support and to protect the zero degree cables.

When any of the cables are exposed to moisture by cuts or gouges in the rubber, they can deteriorate by
rusting. Because of this, any exposed cables should be repaired as soon as possible. Any damaged
zero degree cables that protrude above the surface of the track should be clipped or ground down to
below the surface of the track to prevent additional damage due to unraveling. Cuts, gouges and minor
wear on guideblocks are not expected to cause operational problems. However, a track that has two or
more consecutive guideblocks missing should be replaced since this could lead to untracking, possibly
damaging other undercarriage components.

STORAGE PREPARATION

IMPORTANT: When the track system is not going to be used for a length of time, store the tracks in a
dry, protected place. Leaving your track system outside, open to the weather, will shorten its life. Park
the track system on level ground. Block the front and rear of the belts to prevent the tracks from rolling
unexpectedly. Inspect the track system and touch-up spots where the paint has been worn away (use a
good quality primer paint).

REMOVING FROM STORAGE

1. Make sure the air spring pressure is inflated to 100 psi.

2. Inspect rubber belt for cuts or gouges and repair any damaged cables.

3. Check for missing or damaged guideblocks and replace as necessary.

4. Lubricate all grease points.

5. Repack the wheel bearings. Use Bearing Gard MK1 or equivalent lubricant.

6. Check the seal for wear and replace if necessary.

7. Check the wheel hubs and make sure the nuts are properly torque to 350 ft.-lbs.

When performing maintenance work, wear sturdy, rough-soled work shoes and protective equipment for
eyes, hair, hands, hearing and head. Follow Operator’s Manual instructions to ensure safe and proper
maintenance and repair.

Your local, authorized dealer can supply genuine replacement parts. Substitute parts may not meet
original equipment specifications and may be dangerous.

BE CERTAIN THAT ALL POWER IS SHUT OFF TO THE GRAIN CART BEFORE PERFORMING ANY
MAINTENANCE OR REPAIR WORK.
