Key Features

Overview

Efficient

Electronically controlled hydrostatic drive system and multi-function joystick provide high levels of performance and maneuverability.

Comfortable Operation

The cab is ergonomically designed to increase operator comfort and visibility. The advanced monitoring system tracks machine operating conditions and keeps the operator informed of all vital machine functions.

Reliable

Proven hydrostatic design combined with world class pump and motors results in a very reliable tractor. Undercarriage components are designed for longer life compared to leading competitor.

Ease of Service

SEM tractors are designed for easy access to reduce overall service time. The machine's electronic control module allows for quick troubleshooting.

Hydrostatic Drive System

Upgraded hydrostatic system not only leverages Caterpillar automatic, dual path, hydrostatic drive with electronic control technology of the third generation TTT, but also increases efficiency and reliability. Adopt Rexroth German new generation one case drive pump to combine control valve, track motor, simplified hose line design, continue to increase the reliability. Caterpillar high pressure hose provides reliability and durability. Caterpillar control technology provides accurate control and high transmission efficiency. Integrated the hydrostatic oil tank and implement hydraulic oil tank to improve filtrated precision and cooling capability of hydraulic system, increasing reliability and reducing maintenance cost. Maintenance costs are reduced by 60% when compared competitors with torque converter and transmission and rear axle. Counter rotation, power turn and infinitely variable speed save lots of time,increasing working efficiency.

Comfortable Operation

Counter rotation—Tracks counter rotate to provide best in class maneuverability. Powered turn—Machine maintains full power through turns to increase productivity. Cruise control — Operators can retain previous speed settings which makes operation easily. Multi-function joystick allows for counter-rotation, powered turn and cruise control. Pilot joystick control provides comfortable precise blade operation.

Semi-Universal Blade

SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade. Designed for superior load retention and penetration in tightly packed materials. L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration. Blades feature a strong box section design, made from high tensile strength steel to stand up to the most severe applications.

Undercarriage

Undercarriage is provided by China industry expert ensures high reliability and resistance to wear. Carrier rollers track rollers and idle rollers are all maintenance free. Planetary final drive design delivers increased torque ratio for higher transmission effi ciency and lower maintenance cost. Durable final drive bearings and multiple wet disc brakes provide reliability, reduce system heat and extend overall life.

Structures

Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to identify and protect high stress areas. Advanced structure welding technique, relieving welding stress.
