Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland TX60 series combines, covering the TX62, TX63, TX64, TX65, TX66, TX67 and TX68. It works through the machine in the order the crop travels, from the grain header and straw elevator through threshing, separation, cleaning and grain storage, then the engine, air conditioning, hydraulic and hydrostatic systems. The electrical section is the largest and the most useful: circuit diagrams with a full component key, flow-chart troubleshooting that names the voltage to expect at each module pin, and the calibration procedures for the InfoView monitor, the header and the ground speed.

New Holland TX60 Series (TX62-TX68) Common Problems This Manual Covers
The header drops suddenly during operation, or will not reach minimum or maximum height.
The troubleshooting chart handles both, and it starts with a measurement rather than a part. Disconnect the header height sensor R4, lift the header to end of stroke, then check the voltage at X57/08 of the header height control module A3: it should read 7.5 volts with pressure sensor B13 at maximum pressure and 2.0 volts at minimum. If those are wrong, the chart sends you to specific wires, 238 Br and 237 Gn, before it ever suggests replacing the module.
Manual Section: Section 16 - Electrical System: TroubleshootingA gauge, warning lamp or buzzer behaves oddly and you cannot find its circuit.
Use the component key that accompanies each circuit diagram. Every relay, fuse, sender, gauge and solenoid is listed with its designation and the diagram line it appears on, so B4 hydrostatic oil pressure or H9 unloading tube open can be found in seconds. The diagrams are also grouped by model and serial-number range, so check you are reading the sheet that matches your machine.
Manual Section: Section 16 - Electrical System: Circuit DiagramsHeader height or ground speed readings are wrong after a repair.
Recalibrate rather than adjust. The electrical section closes with three calibration procedures: the InfoView monitor, the header and the ground speed. A sensor that has been disturbed or replaced will read plausibly but wrongly until it is calibrated, and the troubleshooting charts assume calibration has already been done.
Manual Section: Section 16 - Electrical System: CalibrationsFrequently Asked Questions
Which combines does this manual cover?
The TX60 series as a family: TX62, TX63, TX64, TX65, TX66, TX67 and TX68. The circuit diagrams name the models and their serial-number ranges on each sheet, so you can see at a glance whether a given diagram applies to your machine.
Can I search the text in this PDF?
No. This document is a page scan without a text layer, so text search and copy will not work. It prints cleanly and every page is legible, and the bookmarks let you jump straight to a section, but plan to navigate by the contents and the section numbers rather than by searching.
How useful is the electrical section?
It is the reason to have the book. It gives the diagram conventions and symbol key, the location of every main component on the machine, the circuit diagrams with a full component key naming each relay, fuse, sender, gauge and solenoid against its diagram line, flow-chart troubleshooting per circuit, and the calibration procedures.
What kind of detail do the troubleshooting charts give?
Real measurements at real pins. For a header that drops suddenly, the chart has you disconnect the header height sensor R4 and check the voltage at X57/08 of the header height control module A3: 7.5 volts with the oil pressure sensor B13 at maximum pressure and 2.0 volts at minimum, which are 75 and 20 percent of the voltage at X57/39. It then branches to the exact wire numbers to test.
Which calibrations are covered?
Three, at the end of the electrical section: the InfoView monitor calibration, the header calibration and the ground speed calibration.
What format is this New Holland TX62, TX63, TX64, TX65, TX66, TX67, TX68?
