2001 McCormick CX50, CX60, CX70, CX80, CX90 & CX100 Tractors Operator's Manual (P/N OM 9-2001)

McCormick’s 2001 CX Series Operator’s Manual covers the CX50, CX60, CX70, CX80, CX90, and CX100 in cab and platform configurations. Publication OM 9-2001 was first issued in February 2001 and revised in December 2001. Its scope is tractor operation, adjustment, and scheduled maintenance; internal engine and transmission overhaul requires separate service documentation.

• Transmission and traction: Synchromesh and Powershift operation, optional creeper use, Mechanical Front Drive, differential lock controls, and cold starting with Thermostart or ether equipment.

• Hitches, PTO, and hydraulics: Rear hitch preparation, position and load control, Auto Hitch adjustment, Ride Control, front and rear PTO operation, and remote hydraulic equipment.

• Instrument calibration: Digital cluster programming for tire radius, implement width, service reminders, and True Ground Speed Sensor calibration, plus analog speedometer settings.

• Wheels and ballast: Front-wheel toe-in adjustment, tread-width changes, steering stops, tire matching, wheel-fastener torque references, and ballast selection.

• Scheduled maintenance: Engine and transmission oil service, fuel-filter replacement and air removal, cooling-system maintenance, drive-belt adjustment, and cab-filter servicing.

• Electrical service: Battery removal and installation, lamp replacement, fuse assignments, relay-location views, and implement-socket terminal diagrams.

This manual is suited to trained operators handling routine checks and adjustments; the main service sections call for an authorized McCormick dealer.

Implement Setup and Field Controls

The rear hitch instructions explain how position, load, drop-speed, and upper-limit controls affect implement movement. The diagnostic display identifies electrical and electronic system status, but a normal indication does not rule out incorrect control settings or hydraulic problems.

Front-hitch coverage distinguishes the single-acting Kitchin system from the double-acting Hydrac system. Rear PTO sections identify single-shaft, dual-shaft, and shiftable arrangements, while the trailer sections cover both pneumatic and hydraulic brake couplings.

Instrument settings: Tire-radius programming and dynamic calibration account for changes in tire size and loaded rolling radius. These procedures help keep ground-speed, distance, and area readings useful after a tire change. The Speedometer Calibration Chart provides the separate switch settings used by the analog cluster.

Deluxe and low-profile cab sections explain heating, ventilation, air-conditioning controls, and filter access. The tire-pressure and load-capacity charts support wheel and ballast selection, alongside front-to-rear tire-matching information for MFD tractors.

Fuel, Lubrication, and Scheduled Service

Fuel-filter procedures distinguish CX50/CX60 tractors from the larger models. Fuel-system air removal covers service-related air entry and the Thermostart connection where fitted. The manual warns that incorrect bleeding and premature cranking can damage the injection pump.

The transmission/hydraulic filter section identifies the change to an integral filter and by-pass screen at P.I.N. JJE2000274. Its illustrated component breakdown helps distinguish the filter arrangements before replacement parts are selected.

The Lubricants and Capacities charts accompany oil-change procedures for the engine, transmission, MFD differential, and planetary hubs. Front PTO servicing distinguishes Kitchin and Hydrac units. Auto Hitch lift-rod adjustment and front-wheel-bearing servicing are also documented; injector replacement and engine valve-clearance checks are assigned to the dealer.

Electrical References and Service Precautions

The electrical section covers the 12-volt, negative-ground system, with bulb specifications, fuse-block layouts, and relay-location views. Seven-terminal and auxiliary three-terminal socket diagrams distinguish North American connections from rest-of-world arrangements.

The MFD clutch is spring-applied and hydraulically released. The manual explains why loss of release pressure can move the front wheels during service, even with the switch off. Its hydraulic-pressure and PTO precautions should be reviewed before work around pressurized lines or rotating equipment.

A Preview of Front-Wheel Alignment Settings

The front-wheel alignment section specifies toe-in of 0–5 mm for two-wheel-drive tractors and 0–2 mm for MFD tractors. A labeled front/rear measurement diagram accompanies separate tie-rod adjustment procedures for the two axle arrangements, keeping the applicable setting tied to the tractor’s drive configuration.

Searchable Text, Chapter Bookmarks, and Included Pages

Text search and diagram detail: Main manual text is searchable, with embedded bookmarks for the major chapters, index, and service-record section. The front cover has no searchable text. Small labels in the seven-terminal socket illustrations require zooming; these are connector references and component-location views, rather than complete tractor wiring schematics.

One printable, English-language 286-page PDF contains 262 pages of introductory material, operating and maintenance instructions, specifications, and index; a 22-page handover and service-record addendum, including its blank pages; one front cover; and one closing page.
