Bush Hog CBH70, CBH80, CBH60 manual Torque Specifications, SAE Grade 2 No Dashes

CBH60, CBH70, CBH80 specifications

The Bush Hog CBH Series is a prominent lineup of compact, high-performance hydraulic blade mowers ideal for maintaining fields, pastures, and overgrown areas. Comprising models CBH80, CBH70, and CBH60, this series is specifically designed for efficiency and durability, making it suitable for various applications, from agricultural uses to residential properties.

One of the standout features of the CBH Series is its robust construction. Each model is built with a heavy-duty frame designed to withstand the rigors of demanding tasks. The decks are made from high-quality steel, offering enhanced durability while maintaining a lightweight design to optimize performance. With reinforced edges and an innovative design, these mowers guarantee longevity and resistance to wear in challenging environments.

The CBH Series integrates advanced hydraulic systems that ensure smooth operation and maneuverability. The hydraulic drive provides excellent power transmission, allowing users to tackle even the most stubborn vegetation with ease. Each model features adjustable cutting height settings, which give users the flexibility to achieve the desired finish. This adaptability is essential for different terrains and types of foliage.

Another key characteristic of the CBH models is their user-friendly design. The intuitive controls allow for easy operation, making it accessible even for those who may not have extensive experience with machinery. The cutting decks feature a quick-release mechanism, streamlining maintenance and facilitating blade changes when necessary.

The CBH80, CBH70, and CBH60 differ mainly in their width and cutting capabilities. The CBH80 boasts an impressive cutting width of 80 inches, making it ideal for large open fields, while the CBH70 offers a 70-inch cutting width, perfectly balancing efficiency and maneuverability. The CBH60, with a width of 60 inches, is designed for tighter spaces, allowing for easy navigation around trees, fences, and other obstacles.

Safety is paramount in the design of the CBH Series. Each model incorporates features such as safety guards and shields to protect users from debris during operation. Furthermore, the mowers are equipped with a quick-stop system that halts blade rotation almost instantly when the operator releases control, enhancing overall safety.

In conclusion, the Bush Hog CBH Series, with its models CBH80, CBH70, and CBH60, embodies a harmonious blend of power, durability, and user-centric design. Equipped with innovative technologies and safety features, these mowers are well-suited for various operational needs, proving to be invaluable tools for anyone looking to maintain their land effectively.
