MTD7122B09 specifications

The Bolens MTD7122B09 is a reliable and efficient garden tractor that caters to both residential and commercial users seeking a powerful machine for their lawn care needs. This model seamlessly blends user-friendly features and robust technologies, ensuring a seamless mowing experience.

One of the standout features of the Bolens MTD7122B09 is its powerful engine. Equipped with a reliable Briggs & Stratton engine, this tractor offers substantial horsepower and torque, allowing users to tackle even the toughest mowing tasks with ease. The engine is designed for durability and longevity, providing consistent performance year after year.

The cutting deck is another remarkable aspect of the MTD7122B09. With a 42-inch cutting width, it allows users to cover larger areas in less time, making it ideal for both small and medium-sized lawns. The deck features three blade cutting systems, allowing for precise cuts while providing a professional-looking finish. The ability to adjust the cutting height offers versatility, making it suitable for various grass types and terrains.

Comfort is a priority with the Bolens MTD7122B09, and this is reflected in its ergonomic seating and easy-to-use controls. The plush seat is designed to provide maximum comfort during long mowing sessions, while the conveniently located controls ensure users can operate the tractor effortlessly. The steering wheel is adjustable, catering to users of different heights.

In terms of technology, the Bolens MTD7122B09 incorporates innovative system features like a hydrostatic transmission, which delivers smooth shifting and eliminates the need for manual gear changes. This transmission technology enhances maneuverability, making it easy to navigate around obstacles in the yard.

Additionally, the tractor supports mulching capability, bagging, and side discharge, offering users multiple options for grass disposal. These features help maintain a tidy lawn while reducing the need for frequent clean-up.

For safety, the Bolens MTD7122B09 includes safety features such as an automatic shutdown when the operator leaves the seat, ensuring that the mower stops when it is no longer in control.

The Bolens MTD7122B09 is not just a lawn mower; it’s a robust gardening tool designed for efficiency and comfort. Its combination of powerful performance, user-friendly features, and innovative technology makes it an excellent choice for anyone serious about lawn care.
