Marker Operation
Both markers can be raised simultaneously, but they only
can be lowered one at a time, alternating from one side to
the other.
If both markers are required down at the same time, run
one marker down, momentarily start to raise it, reverse the
hydraulic lever and lower the opposite marker. Holding the
lever down then will force both markers down.
On open-centers tractor where the oil flow cannot be con-
trolled, the rate of flow of oil from the tractor may be great-
er than the rate at which the marker cylinder can accept it.
The tractor hydraulic control lever will have to be held until
the cylinder reaches the end of its stroke.
Liquid Fertilizer Operation

Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.

To operate the pump, the discharge manifold must be in
the forward position as shown in Figure 2-4. Pumps are
shipped in the rearward position.
To position the manifold forward for operation, loosen the
wing nuts on the manifold and pull the manifold forward.
