G - Front PTO on

H - Front PTO off

J - Three-point hitch, raise

K - Three-point hitch, lower

L - Three-point hitch (quick withdrawal)

M - Selective control valves (rear), extend

N - Selective control valves (rear), retract

O - Selective control valves (rear), float position

P - Selective control valves (front), extend

Q - Selective control valves (front), retract

R - Selective control valves (front), float position

S - Transmission - specified gear

T - Transmission - automatic gear-shifting

U - Maximum speed (IVT)

V - Upper limit for engine speed

W - Add function (edit mode)

X - Delete function (edit mode)

The functions shown here can

• be selected from the drop-down lists when the tractor is stationary (edit mode)
• be “learned” via the tractor's controls when the tractor is moving (learn mode)

On functions that can be selected via the controls (e.g. front-wheel drive on/off and differential lock on/off), the opposite condition can be selected by actuating the control again within 2 seconds.

NOTE: For functions (M) to (R), the electronic selective control valves must be unlocked, and learning requires the time setting to be other than 0.

Function (S) determines which gear the transmission shifts to (gears 1-4). Function (T) determines the highest gear to which the AutoQuad Plus transmission's automatic gear-shift function can shift (gears 2-4).

Maximum speed (IVT)

LX1044400-UN-29NOV07

This screen appears if the speed wheel on the speed control lever is turned during “learning”. Maximum speed in the speed range (dependent on whether the control lever is in forward range F1 or F2) can now be changed. In HMS, the permitted speed range is from 1.5 to 16 km/h (0.9 to 9.4 mph). Faster or slower speeds are not accepted by the HMS. Press the HMS button to return to the HMS screen.

NOTE: Set speed is not attained until the speed control lever reaches its relevant end position.

Upper limit for engine speed

LX1044401-UN-30NOV07

This screen appears if the engine button is pressed during “learning”. The upper limit for engine speed can be set here. Press the HMS button to return to the HMS screen.

NOTE: The speed set here is not attained unless top speed is commanded and there is no intervention by any automatic transmission function.

Editing of maximum speed (IVT) and upper limit for engine speed

LX1044402-UN-29NOV07

Maximum speed and upper limit for engine speed can be changed in the edit mode. To do so, go to the relevant box and select the small window with figures in it.
