Efficiency: electronically controlled hydrostatic drive system and multi-function joystick provide a high level of productivity and maneuverability. Convenient operation: the cab is ergonomically designed for increased operator comfort and visibility. An advanced monitoring system controls the operating conditions of the vehicle and informs the operator about all the vital functions of the vehicle. Reliability: proven hydrostatic design, as well as world-class pumps and motors ensure highly reliable bulldozer quality. Undercarriage components are designed to longer-term lifespan in contrast to leading competitors. Operational capacity: SEM bulldozers are designed for easy access to reduce overall maintenance time. Electronic control module gives the possibility to quickly troubleshooting. Double-circuit hydrostatic drive with electronic control technology
• Hydrostatic system provides higher efficiency and maximum output tractive effort  - 350 kN
• Maintenance costs reduced by 60% compared to competitors that use a hydraulic torque converter and transmission design
• The ability to set the heading speed by pressing the heading function button and holding it for 5 seconds, facilitates the work of the operator and improves productivity
• Reverse rotation and power reversal functions provide excellent maneuverability on work sites
Comfortable operation
• Counterrolling — caterpillars rotate in the opposite direction, which provides better maneuverability in the class
• Turn under load — the car retains full power when turning, which increases its productivity.
• Cruise control — the operator can maintain previous speed settings, which makes work easier.
• The multi-function joystick allows to perform reverse rotation, rotation under load and set cruise control.
• Pilot control with a joystick ensures comfortable and precise blade operation.
S type blade
• Excellent penetration of Type S blade (direct type)
• The blade is located close to the body of the bulldozer, which gives the machine excellent maneuverability and balance, as well as easy penetration of the blade into the ground
• The blades have a robust box-section construction made of high-strength steel, which can withstand the most difficult working conditions
Undercarriage and braking system
• Undercarriage that was produced  by a world-class manufacturer provides high reliability and wear resistance
• Guide rollers, track rollers and carrying idlers are free of maintenance.
• Planetary final drive design provides increased torque ratio for maximum transmission efficiency and lower maintenance costs.
• SG track shoe, 915 mm wide, provides excellent traction performance when working in conditions of both hard and loose soil
• Long-lasting final drive bearings and brakes with multiple oil-cooled discs are highly reliable, reduce system heating and extend overall life
Structure
• Structural details of the vehicle are verified using finite element analysis (FEA) and workload analysis (OMSA), which allows you to identify and protect high voltage areas.
• Advanced welding technologies of structural elements that relieve welding stress
Modular radiator
• New advanced cooling system enables operation at ambient temperatures from -43 ° C to +50 ° C
• Hydraulic-related fan reduces fuel consumption.
• Modular radiator is easy to maintain, remove and repair.
• Radiator grill provides better heat transfer and easy access for maintenance.
Maintenance
• The electronic control unit (ECM) of diagnostic system performs automatic diagnostics of eight key parameters.
• The monitoring system has a three-level alarm that is triggered by signals from various systems to indicate the location of a malfunction, a malfunctioning system or the consequences of a malfunction
• A small volume (only 62 L) of gear oil poured into the hydrostatic system and an extended replacement interval (2000 hours) reduce maintenance costs by 50%.
• Implement valve group mounted outside the hydraulic fluid reservoir provides easy access for inspection and maintenance.
