Overview
Cat® forestry mulchers have industry-leading features to ensure you are getting the best productivity from a mulcher for tracked and wheeled excavators, all while keeping your work environment and equipment safe.
Features At A Glance
Reliable Performance
- Cut trees from 152 mm (6 in) up to 407 mm (16 in) in diameter.
- Two rotor types:
- Standard – rotor with teeth only
- Bite limiter – rotor with teeth separated by ribs to help prevent rotor stalling and creates finer shredded materials
- Variable torque hydraulic piston motor shifts between high speed, low torque and low speed, high torque to give you speed when you need it and power when it counts.
- Brackets allow the mulchers to be mounted to a variety of excavators within each size class.
- The staggered tooth design reduces stalling and jamming.
- Mulcher teeth options vary by application and preference on final material size:
- Standard: Most commonly used option. Fairly fine final product used where there is minimal rock present and durability is needed.
- Rock Crushing: Larger final product, but can work in applications where rocks are present.
- Bite Limiter: Very fine final product due to aggressive edge of the blade with the limiters and counter knives. Use where rocks are minimal and there are large amounts of standing timber.
- Hardened counter blades reduce finished material size and increase the rate of composting.
Easy Maintenance
- Access internal components quickly and easily with bolt-on service panels.
- Poly chain belt driven transmission eliminates slippage on startup, reducing maintenance costs.
- The motor is integrated into the frame to protect it from dust, damage, and impact from falling debris.
- Ensure service panel security with access bolts recessed into the panel, protecting them from debris.
- Get back to work faster with field-replaceable wear parts.
Prioritized Safety
- Hydraulic mulching door keeps the work environment and equipment safe by dispersing materials according to your application and surroundings.
- The mulching door operation is controlled by electric diverter valve or medium pressure hydraulic kits from the cab.
- Door closed – right-of-way clearing, near powerlines and pipelines, and roadside maintenance.
- Door open – vegetation management, jobsite clearing, forest wood fuel removal, and firebreaks.
- Flow control valve protects the motor from excessive flow.
- Ground-level primary grease points keep you safe while performing daily maintenance.
- Bolt-on, replaceable skids keep the mulcher from going into the ground or into materials expediting wear or causing damage.
Boost Efficiency and Productivity with Integrated Technologies
- Never waste time looking for your attachments again. Cat PL161 Attachment Locator is available on most attachments.
- Track your entire fleet of attachments and machines from one source. Attachments with asset tracking can be viewed within VisionLink® alongside Product Link™ subscribed equipment.
- Keep your assets secure. Attachments with an asset tracker send an alert if they leave an easy-to-setup site boundary.
