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.

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.
