- The drawbar, circle and moldboard make it easy for you to keep the components tight.
- Shims and patented top-adjust wear strips are easy to add or replace, reducing downtime.
- Durable nylon composite wear inserts maximize circle torque and component life.
- Sacrificial brass wear strips between the blade mounting group and moldboard can be easily adjusted and replaced.
- Shim less Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.
- An aggressive blade angle, optimized moldboard curvature and large throat clearance help you work more efficiently by allowing material to roll more freely along the blade.
- Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater moldboard reliability and long service life.
- Link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.
- Proven load-sensing system and advanced electro-hydraulics give you superior implement control and responsive hydraulic performance. Continuously matching hydraulic flow/pressure to power demands generates less heat and reduces fuel consumption.
- Proportional Priority Pressure-Compensating (PPP-C) valves have different flow rates for the head and rod ends of the cylinder. Count on consistent, predictable implement response.
- Balanced hydraulic flow is proportioned ensuring implements operate simultaneously without slowing the engine or implement reaction time.
- Blade Float allows the blade to move freely under its own weight.
- Float both cylinders allowing the blade to follow the ground contours
- Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.
- Large, separate hydraulic oil supplies prevent cross-contamination and provide proper oil cooling, which reduces heat build-up and extends component life.
- Cat XT™ hose allows high pressures for maximum power and reduced downtime.
- Cat Technology makes smart use of technology and services to improve job site efficiency. Using the data from technology equipped machines, get more information and insight into equipment and operations
- Cat technologies offer improvements in these key areas:
