17.4-ton motor grader, 17,390 kg operating weight typically equipped with push block and rear ripper/scarifier. Cat C7.1 six-cylinder engine, 7.01 L displacement, 131 kW net power at 2,200 rpm, 889 N·m maximum torque (ISO 9249), 40% torque rise, U.S. EPA Tier 3 / EU Stage IIIA. 3.7 m (12 ft) moldboard, 509 mm blade height, 735 mm maximum depth of cut, 480 mm maximum lift above ground, 1,928 mm maximum shoulder reach right, blade tip range 40° forward / 5° backward. 297 L fuel tank, 43 °C standard ambient capability, 10,322 mm machine length.

The CAT 140 GC is a new 17-tonne motor grader for road contractors and municipal works departments that build and maintain gravel roads, cut drainage ditches and trim sub-grade ahead of paving. It carries a 3.7 m (12 ft) moldboard and, as typically equipped, a front push block and rear ripper/scarifier, so one machine can rip a potholed road surface and regrade it in the same shift. All-wheel drive is available as an option for sand and loose gravel.

The Cat C7.1 engine is certified to U.S. EPA Tier 3 / EU Stage IIIA and runs without DPF or SCR aftertreatment, so there is no DEF to source and less exposure to local diesel quality — a practical fit for road programmes in Africa, the Middle East, Latin America and Central Asia. Standard Eco mode, which Caterpillar rates at up to 5% better fuel economy than running without it, lowers fuel cost on long rural maintenance contracts.

Machines are brand-new and ship from our yard with the complete export document pack. FOB China and CIF prices are quoted on request.

Why This Machine

Product Features

Six points that decide whether the 140 GC fits your road fleet: engine output, emission level and fuel use, blade reach, wear-part cost on the circle, service time, and the attachments it can carry.

01
Powertrain

Cat C7.1 — 131 kW net, 889 N·m torque

Six-cylinder 7.01 L Cat C7.1 rated 131 kW net at 2,200 rpm, with 889 N·m maximum torque (ISO 9249) and 40% torque rise, which holds ground speed as blade load increases. A powershift transmission delivers drawbar power to the tandem, and Electronic Throttle Control sets engine output to the task. All-wheel drive is an option for loose gravel, sand and soft shoulders.

02
Emissions

Tier 3 / Stage IIIA — no DEF, standard Eco mode

Emissions equivalent to U.S. EPA Tier 3 / EU Stage IIIA, with no DPF or SCR aftertreatment, so there is no DEF to buy or store and less exposure to high-sulfur local diesel. Caterpillar reports up to 5% better fuel economy with the standard Eco mode switched on than without it; the on-demand fan runs only as fast as cooling needs, cutting fuel burn and under-hood heat. 297 L fuel tank.

03
Grading

3.7 m moldboard, 735 mm depth of cut, 1,928 mm shoulder reach

12 ft (3.7 m) moldboard with 509 mm blade height, 735 mm maximum depth of cut, 480 mm lift above ground, 663 / 512 mm side shift and 1,928 mm shoulder reach to the right for ditch and bank work. A moldboard extension adds 605 mm of blade width for wider road passes. The optional Digital Blade Slope Meter shows cross-slope in the cab, reducing the need for grade checkers on foot next to the machine.

04
Durability

Drawbar-circle-moldboard built to hold tolerance

Standard drawbar-circle-moldboard with hardened circle teeth; replaceable wear inserts keep the circle tight, so blade play is corrected by swapping inserts rather than rebuilding the circle. The optional slip clutch protects the circle drive when the blade hits a buried rock or culvert, and the optional Circle Saver cuts daily greasing and circle-and-pinion repair cost.

05
Serviceability

Grouped filters, oil-bathed brakes, standard bottom guard

Fuel, engine air and oil filters are grouped in one location to shorten service stops. Hydraulic brakes run in oil and need no routine adjustment. A standard bottom guard covers the transmission and filters, with additional guarding available as an option. Product Link reports hours, fuel use, idle time and diagnostic codes through VisionLink.

06
Versatility

Push block, ripper, scarifier and front blade options

The 17,390 kg typically equipped weight includes a front push block and rear ripper/scarifier for breaking up compacted or potholed gravel before regrading. Counterweight, front lift group with straight or angle front blade, snow wing mounting and auxiliary hydraulic lines are available for municipal and seasonal work.
