2.4. PTO SAFETY
• Never use a PTO driveline without a rotating shield in good working order.
• Ensure PTO driveline is securely attached at both ends before operating.
• Before starting tractor, turn power to PTO to the off position (where applicable).
• Keep body, hair, and clothing away from rotating PTO driveline.
• Ensure the PTO driveline shields turn freely on the PTO driveline.
• Do not exceed operating speed of 540 rpm.
• Keep u-joint angles small and equal. Do not exceed recommended operating
length for PTO driveline.
2.5. HYDRAULIC SAFETY
• Wear proper hand and face protection when searching for hydraulic leaks.
Escaping fluid under pressure can penetrate the skin, causing serious injury
like gangrene. In case of accident, see a doctor immediately.
• Fluid leaks in the hydraulic lift cylinders or hoses will allow the auger to lower
inadvertently. Repair all leaks and breaks immediately. Rupture could cause
damage and/or personal injury.
• A hydraulic lift is faster than a conventional hand crank—always clear area of
personnel before raising or lowering.
• Do not disconnect hydraulic couplers when hydraulic system is pressurized.
For the correct procedure, consult this manual or your tractor manual.
• Relieve pressure before unhooking hydraulic lines.
• Inspect hydraulic fittings and hoses for damage on a daily basis. Repair if
damaged.
• Ensure that the hydraulic line(s) is (are) properly connected and secure.
• Keep hydraulic line(s) away from moving parts.
• Clean connections before connecting to equipment.

• Tighten with 1” x 2-1/2” bolts (30) and 1” locknuts (31). Use 1” SAE washers (32) as spacers between the tabs and the bracket (one for each side).
See Figure 3.24.
WARNING
Do not remove tube support until instructed to
do so in step 12.
5. Attach axle arms to flex frame as shown in Figure 3.30. Start by passing a 1”
x 5” bolt through the axle arm, stabilizer bracket, 1” flat washers and the push
the bolt through the hole in the flex frame. Secure on the backside with a 1”
locknut. This is a pivot point, tighten only to snug. Repeat this process for the
opposite side.
Note: It may aid alignment to use a stand to hold up the axle arms.
6. Install the short crossmember by placing it between the lower arms. Attach a
stabilizer side plate to each end of the short crossmember and secure with
four 3/4” x 4-1/2” bolts and locknuts. Only put the nuts on the end of the bolts
for now.
7. Attach the stabilizer braces to the short crossmember using a 5/8” x 2” bolt
and locknut. Leave the bolts loose for now.
Note: The bend angle of the stabilizer brace is different at each end. Attach the end
with a smaller bend to the short crossmember.
8. Secure the two stabilizer brackets and stabilizer braces using a 5/8” x 2-1/2”
bolt and locknut. The stabilizer braces should sandwich the brackets. The
short crossmember may have to be moved around to get the bolt in.
9. Bolt the remaining hole in the two stabilizer brackets together with a 5/8” x
1-3/4” bolt and locknut.
10. Push the short crossmember toward the stabilizer brackets until it fits gently
between the two frames, do not wedge the short crossmember in between
the lower arms too tight.
11. Tighten all the bolts in the stabilizer and crossmember making sure nothing
moves. Ensure the 1” lower arm bolt is left only snug, as it remains a pivot.

Figure 3.73
71’ - 111’ 3.18. AUGER-TO-TRACTOR HOOKUP
Since the auger and tractor
become an integral unit during
transport, placement, and
operation, the configuration and
measurements between the
tractor drawbar and the tractor
PTO driveline are very
important.
Figure 3.74 illustrates the ideal
measurements. Most tractors fall into this range.
• Dimension (B) may range from 8” (20.3 cm) to 10” (25.4 cm) with 9” (22.9
cm) being ideal.
• If dimensions (A) and (B) on your tractor are as shown, then dimension

WHEATHEART - SA FLEX AUGER 5. OPERATION
71’ - 111’ 5.3. OPERATING PROCEDURE
CAUTION
Auger must be hooked up to tractor for all
operations, including transport, raising,
placement, and augering of grain.
1. Ensure auger is properly placed and complete the pre-operational checklist.
If everything is satisfactory, prepare for one hour of operation at half speed.
NOTICE
To prevent equipment damage, lower the outriggers before
operating the auger.
Important: Do not operate auger with intake hopper in transport position. This will damage
the u-joint.
2. Using the hydraulic controls, position the intake hopper as shown in Figure
5.1.
Note: Use the hopper drive wheel and flex cylinder at the same time to position the flex
tube.
Important: When starting auger for the first time, be prepared for an emergency shutdown in
case of excessive vibration or noise. Auger may run rough until tube is polished.
3. Roughly position the truck trailer centered at the intake hopper and use the
hydraulic controls to position the intake hopper under the truck hopper.
4. Start tractor and idle at low rpm. Slowly engage PTO drive.
5. Gradually begin feeding grain into intake hopper, bringing auger speed up to
about 300 rpm. Do not overfeed intake hopper on initial loads; keep feed of
grain at about half capacity.
6. Once one truck hopper is empty, use the hydraulic controls to move the
hopper under the remaining hopper and continue unloading truck.
NOTICE
Running auger empty at high speeds results in excessive
wear. Do not exceed 540 rpm.
7. After auger tube is polished and runs fairly smoothly , proceed to unload at full
speed of 540 rpm.
8. After initial run, slow auger down until empty of grain and then stop.
9. Lock out tractor and conduct a complete inspection of auger following the
checklist (see “Pre-Operational Checklist” on page 87).
After initial start-up and inspection, auger should be inspected at least 3 more
times during the first 10 hours of operation.
After Break-in: Maintain auger speed of 300 to 540 rpm under normal use for
maximum efficiency and to reduce the chance of plugging.
30651 R5 89
5. OPERATION WHEATHEART - SA FLEX AUGER
5.3. OPERATING PROCEDURE 71’ - 111’
Once auger is broken in, the checklist should be a part of the daily routine before
operating auger.
5.3.2. OPERATING WITH A FULL LOAD
1. When operating the auger , always work with a second person in a position to
monitor the operation and initiate a shutdown in case of emergency.
2. Monitor the auger during operation for abnormal noises or vibrations.
3. Shut off all power before making adjustments, servicing, or cleaning the
machine.
4. If grain overflows through safety discharge door, then the auger is loaded
beyond its capacity; reduce volume of feed to intake hopper. Remember,
auger capacity will decrease at steeper angles of operation.
5. Engage and disengage PTO drive with tractor engine at idle speed. This will
reduce stress on drive components and on shear bolts.
6. Do not exceed 540 rpm on the PTO.
DANGER
Rotating Flighting Hazard!
To prevent death or serious injury:
• Keep away from rotating auger flighting.
• Do not remove or modify auger flighting
guards, doors, or covers. Keep in good
working order. Have replaced if damaged.
• Do not operate the auger without all
guards, doors, and covers in place.
• Never touch the auger flighting. Use a
stick or other tool to remove an obstruction or clean out.
• Shut off and lock out power to adjust, service, or clean.

WHEATHEART - SA FLEX AUGER 5. OPERATION
USE OF GRAIN SPREADERS: Many grain spreaders cannot handle the large
capacity of some augers. Some augers plug, causing damage to the flighting
and other drive components. This type of damage is not covered by warranty.
Hints on how to avoid this...
• Get a larger spreader, if available.
• Remove the spreader.
• Make sure spreader is turned on.
• Center auger spout on spreader.
• Do not lower auger spout into spreader.
• Suspend the spreader from bin ceiling leaving extra room for excess
grain to flow over the spreader.
BIN LEVEL INDICATORS: These augers are fast and bins fill up quickly. A full
bin will cause auger to plug, which can damage the flighting and other drive
components. Installing quality grain-level indicators on your bins will allow you
to monitor bin filling and help prevent damage to your auger.
71’ - 111’ 5.3. OPERATING PROCEDURE
5.3.3. SHUTDOWN
NORMAL SHUTDOWN
1. Near the end of a load, decrease auger speed until all grain is clear of
machine.
2. When auger is clear of grain, disengage PTO drive.
3. Shut down and lock out tractor.
EMERGENCY SHUTDOWN / FULL-TUBE RESTART
1. If cleanout covers or safety doors have been opened or removed, close or
replace them before restarting the unit.
NOTICE
Starting the auger when there is grain blockage will result in
damage to the auger.
2. If the auger is shut down for an emergency, lock out tractor before correcting
the problem.
• If the problem is plugging, clear as much of the grain as possible using a
piece of wood, wet/dry vac, or other tool before restarting auger. Do not
reach in and use your hands even if the tractor has been locked out.
3. If auger tube is full of grain, do not restart at full speed. Engage PTO at low
rpm, gradually increasing power until normal operating speed is reached.

5.3. OPERATING PROCEDURE 71’ - 111’
5.3.4. LOWERING AUGER
After operation, move auger to next work/storage area and clean out.
1. Clean entire work area.
2. Disconnect PTO driveline from tractor.
3. Place flex tube in transport position, lock in place with over center lock on flex
frame (see Figure 5.3).
4. Use hydraulic valve to raise intake feed hopper slightly.
5. Remove all supports and chocks.
6. Raise outriggers by first opening the ball valves located on outrigger legs and
then engaging flex auger hydraulics (see Figure 5.1). Put locks in place and
insert retaining pins (Figure 5.2).
Note: Reconnect lift cylinder hose coupler to tractor, if disconnected.
7. Move auger out of working position and lower fully by opening hose valve
and tractor valve, feathering to prevent too rapid a descent.
8. Once valves are open, auger lowers by gravity. As the auger nears the full
down position, the rate of descent increases. Do not operate with tractor
valve fully open.
9. Lower auger using tractor hydraulics. For SA 111, seat lift assist arm against
the track and the track shoe against the trackstop with slight tension on the
lift cable.
10. Place the steering assembly in transport position. Pull out the lockpin, and
fold the steering assembly down 90° (see Figure 5.1).
WARNING
Do not leave auger in raised position when not
in use. Auger could drop rapidly due to a cable
break.
