LANDOLL 7833 QUICK START NOTES
This instruction is intended to be used with Landoll 7833 HSL production produced after April 1, 2018
with “Tilt Control” or older machines that have been updated with “Tilt Control” system.
Install the main tires onto the HSL hitch being careful to follow the instructions on the decal.
CONNECTING
the HSL to the tractor.
̶
Use the size appropriate hitch ball (pin hole in the ball) for your tractor
̶
Select your tractors “go to” hydraulic circuit. Connect the ½, red coded hoses to this circuit and
set it for “maximum flow” (100%). (the double taped hose end is the pressure side)
̶
Select a second circuit and connect the blue coded hoses to it and adjust it to full flow.
̶
Select a third circuit and connect the yellow coded hoses to it. For field work this circuit will
need to run continuously and be turned down to about 1-1/2 to 2 gpm (10%-20% flow). You
may experience slow folding and unfolding at this flow.
̶
Select a fourth circuit and connect the black coded circuit to it and adjust the flow to full flow.
UNFOLD
the HSL.
̶
Adjust the rear reel cylinders to be somewhere mid-range in their stroke (avoid total retract).
̶
Tip the center section top, rearward until the wing frames lift out of the transport saddles (red
circuit).
̶
Spread the wings to clear the transport saddles by several inches (yellow circuit).
̶
Lower the wings until the gauge wheels are in the proximity of the ground (red circuit).
̶
Continue to open the wings until they completely unfolded (yellow circuit).
̶
Lay the HSL down onto the ground by extending the tilt cylinder (red circuit).
FOLDING
the HSL
̶
Pick the HSL up, rear upward until it is vertical by retracting the tilt cylinder (red circuit).
̶
Fold the wings forward until they contact the poly wear surface. (yellow circuit)
̶
Raise the wings until they can be placed into the transport saddles. (red circuit)
̶
Fold the wings inward until they contact the upper poly wear surface. (yellow circuit)
̶
Lower the wings into the transport saddles. (red circuit)
FINAL ASSEMBLY
of the HSL. Typically, this will include attaching the reel assemblies to the rear of the
machine (please consult the parts manual for a detailed instruction).
WING DOWN PRESSURE
: The wing down pressure manifold is located inside the left-hand side of the
hitch frame. Operate the wing down pressure continuously when working in the field. Turn the wing
down pressure system on (yellow circuit with reduced flow) and confirm the correct pressure for the
width of your HSL.
*******
NEVER EXCEED 1,500 PSI******
̶
7833-25……………450 PSI
̶
7833-30……………650 PSI
̶
7833-35……………875 PSI
̶
7833-40……………1150 PSI
SYNCHRONIZE
the cylinders operating the main hitch tires and the wing gauge wheel tires by fully
extending those cylinders for 5 to 10 seconds after they reach apparent full extension (blue circuit).
SYNCHRONIZE
the cylinders operating the rear reels in the same way (black circuit).
DEPTH CONTROL
(single point control, just left of center on the hitch)
̶
Start shallow and work deeper if needed…start in the “E” to “F” range
TRACKING
and front to rear adjustments (single point control, “Tilt Control”, located on the extreme
left hand side of the hitch)
̶
The HSL must track straight behind the tractor to maintain the correct relationship of the rear
disc units to the disc units in the front row. The HSL may not run perfectly level but it MUST
track straight behind the tractor. (Start in the “C” to “D” range but more so towards “D”)
If the HSL
tracks to the right-hand side
, turn the tilt control adjustment crank
clockwise
lowering the rear gang relative to the front disc row (10 turns per inch).
