BOLT TORQUE CHART

Always tighten hardware to these values unless a different torque value or tightening procedure is listed for a specific application.

Fasteners must always be replaced with the same grade as specified in the manual parts list.

Always use the proper tool for tightening hardware: SAE for SAE hardware and Metric for metric hardware. Make sure fastener threads are clean and you start thread engagement properly.

All torque values are given to specifications used on hardware defined by SAE J1701 MAR99 & J1701M JUL96.

RB750-4, RB850-4 specifications

The Woods Equipment RB850-4 and RB750-4 are two powerful and efficient rotary tillers designed for serious lawn and garden care. Both models embody rugged construction and advanced technology, making them ideal choices for homeowners and professionals alike.

The RB850-4 offers an outstanding working width of 85 inches, enabling the user to cover a significant area in a shorter time frame. This model is equipped with four durable, cast iron gearboxes that facilitate smooth operation and prolong the lifespan of the equipment. The adjustable tilling depth allows operators to customize the soil preparation according to specific needs, whether for seedbed preparation or incorporating organic matter into the soil.

On the other hand, the RB750-4 features a slightly narrower working width of 75 inches, providing agility in tighter spaces without compromising performance. It also employs the same four cast iron gearboxes for reliable power distribution. The robust tines of both models are specifically designed for efficient soil mixing, turning and aeration, enhancing soil structure and health.

One of the main features of both the RB850-4 and RB750-4 is the innovative Quick-Connect attachment that streamlines the process of interchanging with other implements. This design principle enhances productivity, allowing users to quickly switch tools without wasting time. Moreover, both models are engineered for compatibility with a broad range of tractors, enhancing their adaptability across various farming and gardening applications.

The advanced technologies incorporated into these tillers also include a protective shield that reduces the risk of debris getting stuck in the tines. This not only extends the operational capability of the tillers but also enhances user safety during operation. Additionally, the rear roller on both models ensures a smooth finish, leveling the soil after tilling.

In summary, the Woods Equipment RB850-4 and RB750-4 rotary tillers combine power, efficiency, and versatility into a high-performance package. With their robust design, adjustable features, and advanced technologies, these tillers stand out in the market, promoting healthier soil and contributing to successful gardening and landscaping outcomes. Whether for intensive tilling or light garden maintenance, both models offer unparalleled value and reliability, making them a worthy investment for both amateur and professional users.
