NewAvailableYear 2026

17.7-ton motor grader, 17,706 kg operating weight typically equipped (5,136 kg front / 12,570 kg rear axle), 15,185 kg base. Cat C7 six-cylinder engine, 7.2 L displacement, 139 kW net base power in 1st gear and 139–154 kW Variable Horsepower range at 2,000 rpm, 1,076 N·m maximum torque, 46% torque rise, emissions equivalent to U.S. EPA Tier 3 / EU Stage IIIA. 4.3 m (14 ft) moldboard, 686 mm high and 25 mm thick, 790 mm maximum depth of cut, 2,261 mm maximum shoulder reach outside tires, blade tip range 40° forward / 5° backward. 8-forward / 6-reverse powershift transmission, 305 L fuel tank, 50 °C high-ambient capability.

The CAT 160K is a new 17.7-tonne motor grader in the 14 ft blade class, bought by highway contractors, earthworks companies and mine operators for building and maintaining roads, spreading base material and keeping quarry and mine haul roads in shape. Its 4.3 m moldboard covers a standard lane in fewer passes than a 12 ft machine, and the rear ripper/scarifier option breaks up compacted surfaces before regrading.

The Cat C7 engine emits equivalent to U.S. EPA Tier 3 / EU Stage IIIA and needs no DEF, which keeps fuelling simple on remote sites across Africa, the Middle East, Latin America and Central Asia. Variable Horsepower adds up to 15 kW in the higher gears used for long grading passes, while the lower 139 kW setting in 1st gear limits wheel slip and fuel burn in heavy cuts.

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 160K fits your road or haul-road fleet: power delivery, emission level and fuel use, blade size and reach, circle wear parts, braking, and daily service access.

01
Powertrain

Cat C7 with Variable Horsepower — 139 to 154 kW net

Six-cylinder 7.2 L Cat C7 rated 139 kW net in 1st gear, stepping up to 154 kW in higher gears through Variable Horsepower (VHP) at 2,000 rpm. 1,076 N·m maximum torque at 1,000 rpm (gears 4–8) and 46% torque rise. The 8-forward / 6-reverse powershift countershaft transmission has direct drive, electronic shift control and overspeed protection; AutoShift is optional.

02
Emissions

Tier 3 / Stage IIIA equivalent — no DEF required

The C7 emits equivalent to U.S. EPA Tier 3 / EU Stage IIIA (Tier 2 / Stage II equivalent configurations exist for some countries). There is no SCR system, so no DEF supply is needed on remote sites. A hydraulic demand fan runs only as fast as cooling needs, and Eco mode, Electronic Throttle Control and engine idle shutdown are standard to cut fuel burn during standby. 305 L fuel tank.

03
Grade Control

4.3 m (14 ft) moldboard, 790 mm depth of cut

4,267 × 686 × 25 mm moldboard with hydraulic sideshift and tip, 790 mm maximum depth of cut, 943 / 851 mm sideshift and up to 2,261 mm shoulder reach outside the tires for ditch cleaning and bank sloping. Load-sensing PPPC hydraulics give proportional blade response. The AccuGrade Attachment Ready Option prepares the machine for AccuGrade positioning, guidance and automatic blade control.

04
Durability

Replaceable circle and moldboard wear parts

The 6-shoe drawbar runs on replaceable nylon composite wear strips, and brass slide-rail wear strips between the blade mounting group and moldboard can be adjusted and replaced, so blade play is corrected with low-cost inserts instead of major repairs. A circle drive slip clutch is standard and protects the drawbar, circle and moldboard when the blade strikes a fixed object; Circle Saver is optional.

05
Safety

Oil disc brakes at every tandem wheel

Four-wheel air-actuated oil disc service brakes sit at each tandem wheel, with a sealed, oil-cooled multi-disc parking brake. Built-in lock check valves, optional blade lift accumulators that absorb impact loads, an articulated frame with safety lock and a ground-level engine shutdown are standard safety items for haul-road and public-road work.

06
Serviceability

Left-side ground-level service, SOS sampling ports

Routine service points are grouped on the left side at ground level. Standard SOS oil-sampling ports on engine, hydraulic, transmission and cooling systems support condition-based maintenance. Fuel-water separator, lockable caps on all fluid fills, lockable battery boxes and extended-life coolant rated to -35 °C, a 24 V electrical system and a 115 A alternator are standard.
