- Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise control.
- With an aggressive blade angle, optimized moldboard curvature and large throat clearance, 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 provide greater moldboard reliability and long service life.
- Link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.
- Proven load-sensing and advanced electro-hydraulics give you superior implement control and responsive hydraulic performance that makes operators' jobs easier.
- Continuously matching hydraulic flow/pressure to power demands reduces heat and optimizes power.
- Proportional Priority Pressure-Compensating (PPP-C) valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
- Hydraulic flow is proportioned to give you confidence that all implements operate simultaneously without slowing engine or implement speed.
- Blade Float allows the blade to move freely under its own weight.
- Float both cylinders, to allow blade can follow the contours of the ground.
- Float one cylinder to permit the toe of the blade to follow a hard surface while the operator controls slope with the other cylinder.
- Large, independent hydraulic oil supplies prevent cross-contamination and provide proper cooling, reducing heat build-up and extending component life.
- Cat XT™ hose allows high pressures for maximum power and reduced downtime.
- Grade technologies combine digital design data, in-cab guidance, and automatic blade controls to enhance grading accuracy, reduce rework, and lower costs related to production earthmoving and rough, fine and finish grade applications.
