1. M11-C Cummins engine delivers great power, performance and stability.
2. German ZF electronic-hydraulic control power shift gearbox offers 6 forward gears and 3 reverse gears for easy operation.
3. Imported rear axle uses a differential to provide sufficient traction to wheels on one side of the motor grader when wheels on the other side tend to slip on the road surface. The middle and rear wheels are fitted with planetary gear for reliable operation.
4. Tandem drive uses gears for stability and reliability in power transmission.
5. Road grader 731M is a rear-wheel-drive vehicle, with the front axle forced to turn during steering. The front axle has been put through a process known as cascade welding.
6. Maximum angle of steering: 50°. Large oscillation angle of front axle and camber angle of front wheels allow the motor grader to adapt to various tough road conditions. The result is precisely level ground.
7. Wet multi-disc brake comes with twin hydraulic circuits for steady braking motion, maximum safety and maintenance-free performance. Imported brake valve and pressure relief valve are available.
8. Spacious cab offers a wide-angle view. Three-level alarm indicators and various other monitoring instruments ensure maximum safety. Ergonomic layout design of control elements makes for great comfort ion operation. Vibration-damping cab seat is adjustable in 3 directions, allowing cab driver to operate the console with great ease.
9. Falling object protective structures (FOPS) and rollover protective structure (ROPS) are available.
