Reinforced edges and wear-resistant materials ensure long-lasting performance in tough conditions.
    
• Pin Grabber: Offer fast, secure attachment changes and are compatible with a wide range of tools. Ideal for operators who need flexibility on the job site, they allow switching between buckets, hammers, and grapples. Features a redundant locking system to keep your attachments in place and protect them from damage.

• Hydraulic Connecting S-Type (HCS) Couplers: HCS Couplers offer automatic hydraulic connection with the compact, low-profile design of the S-Type. With advanced functionality such as full hydraulic and electronic connection, hydromechanical attachments are connected and ready to operate in seconds.
    
• Performance Hammers: Built for high-demand applications, performance hammers deliver maximum impact energy and fast cycle times for breaking concrete, rock, and asphalt. Ideal for heavy-duty demolition, quarrying, and production environments where speed and power are critical.
    
• GC S Hammers: Simplified, silenced models designed for noise-sensitive environments. They maintain solid performance while reducing sound levels, making them ideal for urban job sites, residential areas, and regulated zones. Ideal for site prep, light demolition, foundry and quarry applications.
    
• Mulchers: Ideal for forestry and agriculture applications. Mulchers clear land and manage vegetation by shredding brush, trees, and undergrowth into fine mulch. Their high-speed rotors deliver fast, consistent results, with interchangeable teeth to suit different materials and desired final mulch size.
