PL5200 Planter Table of Contents Index Operation
3. Install wing flex lock pins at wing pivots.
4. Retract the tractor hydraulic fold lever to fold the
machine. Keep lever retracted until wings are
fully folded.
5. Set the tractor hydraulic fold lever to “Neutral”.
Folding with 2-Point Hitch
1. Extend the tractor hydraulic lift assist lever to
raise the planter. Keep the tractor lever extended
until the rear of the planter is fully raised.
2. Set the tractor hydraulic lift assist lever to
“Neutral”.
3. If necessary, install the lift assist lock cylinders.
4. Raise the front of the planter using the 2-point
hitch.
5. Remove the both wing lock pins on toolbar
coupling.
6. Install wing flex lock pins at wing pivots.
7. Retract the tractor hydraulic fold lever to fold the
machine. Keep lever retracted until wings are
fully folded.
8. Set the tractor hydraulic fold lever to “Neutral”.

Air System
The air system consists of two hydraulic fans on bulk
seed hopper configured PL5200 Planters. One
hydraulic fan supplies air for the seed delivery (1)
and the other hydraulic fan supplies air for the meter
operation (2).
Fan rpm is adjusted using the tractor remote
hydraulic flow control.
A sensor from the seed monitoring system measures
and reports the air to the in-cab console.
In case of insufficient fan air or significant
seed delivery air leaks, seed flow may be
irregular or stop.
Some rows have lines to sample metering air
pressure which is measured in a sensor chamber.
The sensor reading is fed back to the console for
pressure control. Air pressure is adjusted to preset
target in the console.
At the airbox (3), air is mixed with seed from the
hopper and flows out the airbox manifold ports into
seed hoses to the rows.
If seed delivery air flow is insufficient, the
indication will be low seed rate alarms. If fan
speed and direction are as recommended,
check for air leaks in the seed delivery
system.
A screen (4) above each seed meter vents the
delivery air. The vent has two functions:
1. Releases delivery air while retaining the
delivered seed.
2. Controls bulk seed delivery.
When the meter inlet is filled and seed fills the tube
above the inlet, the screen becomes blocked by
seed, shutting of f the air flow to that meter. As the
meter uses seed, the screen is exposed and air
resumes flowing, carrying more seed to the meter.
It takes about a minute to initially fill the
seed meters.
