Assembly - 1450 Round Bale Carrier
RPU Assembly
• Remove lift cylinder and install pilot check assembly.
• Reinstall cylinder at base end only.
• Lubricate all pins involved in RPU attachment with a SAE
multi purpose grease.
• Align arm to pivots with open end of arm facing away
from the carrier and reinstall pins with hardware provided
and torque to specifications called for in the bolt chart.
• Remove the lift cylinder pin from the RPU arm.
• Align the lift cylinder rod and reinstall the pin.
• Adjust the outside bale fork to be positioned at the
end of the lift arm and the inner bale fork 6" (15 cm)
to 8" (20 cm) bigger than the size of bale that is being
loaded.
• Install the hydraulics according to the hydraulic
assembly. Hose clamp is available to attach hoses to bottom of chain rail.
• Recheck all hardware so that every bolted and hydraulic connection on the lift arm is torqued
according to the specifications of the torque charts.
• The RPU cycle should begin with a squeeze action, then lift and rotate. After rotation is
complete the lift continues until the bale is above the carrier beams.
• Release lift arm up when bale is above the carrier beam. Depress lift arm down to release the
bale and return to ground level ready for the next bale.
• For the first operation, cycle the lift arm slowly with the bale and observe the RPU operation.
• Approach the bale slowly; once the bale is captured in the forks press the lift switch. The bale
is squeezed until the pressure in the sequence valve, which is preset at 1800 psi (12400 kpa),
has been achieved.
• If bale is not held in between the forks increase the sequence valve pressure by turning the
setscrew clockwise. Refer to the RPU rotate cylinder drawing for adjustment location of the
setscrew. Verify that the fork spacing is accurate and refer to the drawing on this page for
fork adjustments.
• The lift and rotate sequence won’t begin until the clamp pressure is met within the sequence
valve.
• When the clamp pressure is met, the lifting action should start before the rotating action to
minimize bale damage from the moving ground.
• To increase lift prior to rotate turn the restrictor knob clockwise. Refer to the RPU rotate
cylinder drawing for more information.
• Continue to raise the bale until it is positioned above the carrier beam.
• To release the bale, depress lift arm down.
• Finish the cycle and observe how the bale transits from the forks to the carrier beam. If
transition is smooth with minimum bale binding, assembly is completed. If not, adjust the
forks to a different location and try until loading is smooth.
