HMS - Headland Management System (If Equipped) — Basic Principles

LX1030745-UN-27JAN03

LX1030747-UN-27JAN03

LX1030746-UN-14JAN03

A - HMS on/off switch

B - Record/save switch

C - Program switch

D - HMS indicator light

E - Program 1 indicator light

F - Program 2 indicator light

CAUTION: Using HMS by mistake may cause the tractor or implement to make unexpected movements. For this reason, always delete the sequence of operations as soon as work is finished.

HMS makes it possible to record and save sequences of functions that occur repeatedly and to call them up as programs when needed (tape recorder principle). Two such programs can be stored at any one time. Each of them can include up to 20 functions. The programs remain in the memory until they are deleted, even if the electrical current is switched off.

Recordings may be made of the functions of the following tractor sub-assemblies: differential lock, hitch, rear PTO, front PTO and front-wheel drive.

The distance the tractor moves between functions is also stored. The recording is therefore not dependent on the tractor's speed.

Sample programming (end/start of field)

LX1030747-UN-27JAN03

LX1030746-UN-14JAN03

A - HMS on/off switch

B - Record/save switch

C - Program switch

D - HMS indicator light

E - Program 1 indicator light

F - Program 2 indicator light

Initial situation: tractor operating in field, rear implement is lowered, front-wheel drive is on, rear PTO is on.

	Step	Signal
1.	Press switch (A)	Acoustic signal, light (D) comes on
2.	Press switch (B)	Acoustic signal every 2 seconds, light (D) flashes
3.	Press switch (C) to “1” or “2”	Light (E) or (F) flashes
4.	Raise rear implement *
5.	Switch off rear PTO *
6.	Switch off front-wheel drive **
7.	Press switch (B) **	Light (E) or (F) goes out, light (D) remains on continuously (not flashing)
* The tractor must be driven at a speed of at least 0.5 km/h (0.31 mph). ** This step may be performed with the tractor stationary (clutch depressed)

Initial situation: tractor is at the headland, rear implement is raised, front-wheel drive is off, rear PTO is off.

	Step	Signal
8.	Press switch (B)	Acoustic signal every 2 seconds, light (D) flashes
9.	Press switch (C) to “1” or “2”	Light (E) or (F) flashes
10.	Lower rear implement *
11.	Switch on rear PTO *
12.	Switch on front-wheel drive **
13.	Press switch (B) **	Light (E) or (F) goes out, light (D) remains on continuously (not flashing)
14.	Press switch (A) **	Acoustic signal, light (D) goes out
* The tractor must be driven forward at a speed of at least 0.5 km/h (0.31 mph). ** This step may be performed with the tractor stationary (clutch depressed)

Performing the stored programs

LX1030745-UN-27JAN03

LX1030747-UN-27JAN03

LX1030746-UN-14JAN03

A - HMS on/off switch

B - Record/save switch

C - Program switch

D - HMS indicator light

E - Program 1 indicator light

F - Program 2 indicator light

NOTE: To enable the recorded programs to be performed, the tractor must be driven at a speed of at least 0.5 km/h (0.31 mph).

Before programs are performed that include front-wheel drive and/or PTO functions, front-wheel drive and/or the PTO(s) must be switched on. HMS cannot physically “turn on” the relevant switches.

Before programs are performed that include hitch functions, the relevant lever must be in neutral position.

1. Pressing on/off switch (A) makes HMS indicator light (D) come on.

2. To select the desired program, press program switch (C) to “1” or “2”. Program indicator light (E) or (F) will come on. This light goes out once the program has been completed.
