Hitching Air Cart to Tractor
To ensure consistent planting at the drill, the main frame
of the air cart needs to be level. Set the tongue height
before hitching for the first time.
Refer to Figure 4
1.
Using the crank on the jack stand
, adjust the
height
of the tongue to:
30 inches (76.2cm).
as measured from the ground to the top of the
tongue above the hitch holes center-line. The cart
frame is level at this height.
2.
Back the tractor up to the cart, and confirm that
when hitched, the cart tongue will remain at this
height. If not, adjust either the height of the tractor
hitch, or the location of the hitch strap
.
To adjust the height of the hitch strap
, remove the
bolts
, and reset the strap up or down.
If the strap needs to be moved so far that only one
bolt would be holding it, the strap may be inverted.
Strap inversion requires removing the bolt that
retains the spring hose loop
, and re-mounting it.
3.
Use the jack stand crank
to raise the hitch strap
slightly. Back the tractor so that its drawbar is aligned
with the strap hole.
4.
Shut off the tractor and set the parking brake.
5.
Insert and secure the hitch pin.
6.
Attach the safety chain
to a suitable anchor on the
tractor.
7.
Operate the jack stand crank to retract the inner leg
and base several inches. Secure the crank handle in
the spring clip on the stand.
8.
Remove the pin
at the stand swivel. Remove the
stand and re-pin it on the storage stob
(not visible
in figure) inside the hitch beam.
Make Electrical Connections
The cart has connections in front and back.
Refer to Figure 5
Make sure tractor is shut down with accessory power off
before making connections.
1.
Mate the lighting plug
to the outlet connector on
the tractor. This connection is also passed through to
the back of the cart for the trailing drill.
2.
Mate the seed monitor plug
to the outlet
connector on the tractor. This connection is also
passed through to the back of the cart.
3.
Secure cables so they are clear of moving parts at
the hitch.
