Tramlining
The meter can automatically leave tractor track marks or
“tramlines” in the correct position for subsequent accurate
bout matching of spraying and fertilizing applications.
The system operates by stopping the drive to 2 + 2 feed
rollers (two in the left side of the hopper for the left track
mark and two in the right side of the hopper for the right
track mark) as factory fitted, these will give a tramline track
width of 3 times the drill row spacing.
Refer to Figure 56
Drive to the two feed rollers at the left end of each half of
the meter assembly is disengaged by arms attached to an
electric actuator. These feed rollers are marked with trac-
tor tread decals on the back of the meter assembly.
Drive is automatically engaged/disengaged in the
required sequence by the monitor control box positioned
in the cab. A magnet and sensor on the contact drive
record the bout count. See separate monitor instruction
section for further information and programming
instruction.
Setting up for Tramlines
The drill is set up to do “symmetrical tramlining” for 60 ft.
applicator booms, or “asymmetrical right tramlining” for 40
ft. and 80 ft. applicator booms. See Tramlining instructions
in the Monitor section of this manual. With the optional
NTA2000 dual tramline controls kit, (Great Plains P/N
890-785C) the drill can be set up for 10 bout tramlining for
50 ft. applicator booms or 18 bout tramlining for 90 ft.
applicator booms.
Any seed hose can be connected to the tramline marked
feed rolls on the air distribution chamber. For symmetrical
tramlining, connect the right tramline marked feed rolls to
the desired two rows right of center to leave a mark for the
right sprayer track, and connect the left tramline marked
feed rolls to the desired two rows left of center to leave a
mark for the left sprayer track
Asymmetrical Right Tramlining
Asymmetrical right tramlining only requires the use of the
right tramline marked feed rolls. The actuator arm to the
left tramline marked feed rolls must be disconnected.
For asymmetrical right tramlining connect the right tram-
line marked feed rolls to the desired two rows at the right
end of the drill to leave a mark for the sprayer tracks on
two consecutive passes.
Refer to Figure 57
Disconnect the actuator arm at the left side of the meter
assembly that operates the left feed roll tramline clutch.
This arm will have to be tied over to the right so the “star
shaped” teeth on the arm do not slide over and contact the
feed roll clutch spring.
Note: With the optional NTA2000 dual tramline controls kit,
(Great Plains P/N 890-785C) it will not be necessary to
disconnect the actuator arm.
