MC17542STA, MC17542ST specifications

The McCulloch MC17542ST and MC17542STA lawn mowers are distinguished machines designed for homeowners seeking a reliable and efficient solution for lawn maintenance. These models combine powerful performance with user-friendly features, making them an excellent choice for small to medium-sized lawns.

One of the key features of the MC17542ST and its counterpart, the MC17542STA, is their robust 420cc engine, which provides ample power to tackle various types of grass and terrain. The engine is equipped with advanced technology that ensures reliable starting and efficient fuel consumption, contributing to reduced emissions and lower operational costs. This powerful engine allows users to maintain productivity without the frequent interruptions associated with refueling.

Both models are equipped with a 42-inch cutting deck, which enables wider cutting swath and enhances mowing efficiency. The cutting deck is made of durable materials, ensuring longevity and resistance to wear. Furthermore, the deck height can be easily adjusted, allowing users to achieve their desired grass height with a simple lever adjustment. This feature is particularly beneficial for maintaining a healthy lawn, catering to different grass types and seasonal growth patterns.

The adjustable seat ensures that operators can find their ideal driving position, enhancing comfort during extended mowing sessions. The user-friendly controls are positioned intuitively for easy access, allowing for seamless operation even for those who are new to lawn care.

Another notable characteristic of these models is their zero-turn capability, making it easier to maneuver around obstacles such as trees, flower beds, and garden ornaments. This feature significantly reduces the time spent mowing, as operators can turn with precision and navigate tight spaces effortlessly.

Safety is paramount with the McCulloch MC17542ST and MC17542STA models. They come equipped with safety features such as blade brake systems that stop the blades almost instantly when the operator releases the control. This ensures peace of mind during operation and enhances overall user safety.

In conclusion, the McCulloch MC17542ST and MC17542STA mowers offer an impressive blend of power, efficiency, comfort, and safety. With their powerful engines, wide cutting deck, user-friendly design, and zero-turn capability, they stand out as excellent choices for anyone looking to maintain a beautiful lawn with minimal effort.
