Used CAT 140H Motor Grader for Road Construction and Site Leveling

The Used CAT 140H Motor Grader is a proven road construction machine designed for grading, leveling, ditch shaping, road maintenance and final surface preparation. The machine shown in the photos carries the 140H identification and features a conventional articulated frame, tandem rear drive, front steering axle, hydraulic moldboard system and enclosed operator cab.

For contractors, equipment dealers and infrastructure companies, the CAT 140H provides the working weight, blade control and engine output required for medium and heavy grading work. Its mechanical control layout is also familiar to many experienced grader operators, which makes it a practical option for fleets that value straightforward operation and service access.

CAT 3306 Turbocharged Diesel Power

The CAT 140H uses the well-known Caterpillar 3306 six-cylinder turbocharged diesel engine with Engine Power Management.

According to published 140H specifications, the engine delivers 123 kW / 165 hp in lower gears and increases to 138 kW / 185 hp in gears 4–8. Rated speed is 1,900 rpm, while engine displacement is approximately 10.45 liters.

This variable power arrangement helps the grader match engine output to working conditions. Lower gears support controlled grading, while higher gears provide additional power for faster material movement and road travel.

Direct-Drive Powershift Transmission

The 140H uses a direct-drive powershift transmission with eight forward speeds and six reverse speeds. This gives the operator a broad speed range for precision grading, spreading material and moving between work areas.

Published travel speeds range from about 3.5 km/h in first forward gear to 41.1 km/h in eighth gear. Reverse speeds range from approximately 2.8 km/h to 32.4 km/h.

For fine road finishing, the operator can select a low working speed. Meanwhile, higher gears are useful when the machine needs to travel across a large project site.

3.66 Meter Moldboard for Accurate Grading

One of the main working components of the CAT 140H is its moldboard.

The standard blade is approximately 3,658 mm wide and 610 mm high. The circle provides 360-degree rotation, while hydraulic side shift and center shift allow the operator to position the blade for different grading angles.

This wide positioning range makes the machine useful for:

• Road surface leveling
• Shoulder shaping
• Drainage ditch construction
• Slope trimming
• Material spreading
• Fine grading
• Site preparation
• Gravel road maintenance
• Embankment shaping
• Construction base preparation

The grader can therefore perform both rough shaping and more accurate finishing work.

Reference Technical Specifications

The following values are based on published CAT 140H specifications. Actual data may vary according to production year, tire type, attachments and machine configuration.

The published standard operating weight is approximately 14,724 kg, including fuel, coolant, lubricants and operator in the referenced configuration.

Articulated Frame for Better Maneuverability

The CAT 140H uses an articulated frame that allows the front and rear sections of the grader to work together during steering and blade positioning.

This design is important when grading curved roads, shoulders and confined construction areas. In addition, articulation helps operators maintain the correct machine position while moving material across the road surface.

The front axle also allows wheel lean and oscillation. These functions help the grader adapt to uneven ground and maintain better blade control during demanding earthmoving operations. Published specifications list 18° front wheel lean and 32° front axle oscillation.

Load-Sensing Hydraulic Control

The hydraulic system is designed to provide controlled response according to working demand.

The load-sensing system supplies hydraulic flow when the operator activates the moldboard, circle, lift cylinders or other implements. Caterpillar's 140H literature also describes blade float functions and balanced hydraulic flow for simultaneous implement operation.

For road contractors, smooth blade response is especially important during final grading because small adjustments can directly affect surface quality.

Operator Cab Designed for Visibility

The enclosed cab gives the operator a broad view of the moldboard, front wheels and surrounding work area.

The 140H platform uses conventional mechanical and hydraulic control levers. This layout is easy for experienced motor grader operators to understand and provides direct control of blade lift, side shift, circle rotation, articulation and other functions.

Large windows also help improve visibility around the moldboard. Caterpillar's original 140H literature highlights low-effort controls, suspension seating and wide visibility as key operator-station features.

Suitable for Road and Infrastructure Projects

A used CAT 140H can be applied across many types of projects.

It is particularly suitable for highway base preparation, rural road construction, mining access roads, industrial site development, airport ground preparation and municipal road maintenance.

The machine can also work with optional attachments such as a rear ripper, scarifier or front-mounted equipment, depending on the configuration of the individual unit.

Used CAT 140H Inspection Points

For a used grader, machine condition is more important than the original factory specification alone.

Before purchase, buyers should check the engine, transmission, hydraulic cylinders, circle system, moldboard wear, articulation joint, tandem drives, axle components, tires and cab controls.

The blade circle should rotate smoothly and excessive play between the drawbar and circle should be checked carefully. In addition, buyers should inspect hydraulic leakage, transmission shifting and steering response.

Operating hours, serial number, production year and service history should also be confirmed for the specific machine.

Why Choose a Used CAT 140H Motor Grader?

The CAT 140H combines a 185 hp power range, a 3.66-meter moldboard and a heavy articulated grader chassis in a widely recognized construction platform.

For businesses that need a machine for road maintenance, grading and site development, a properly inspected used 140H can provide a practical alternative to adding new equipment.

Its broad blade adjustment, multiple transmission speeds and conventional controls make it suitable for both rough grading and accurate finishing work.
