MAC GBV 345 specifications

The McCulloch MAC GBV 345 is a high-performance garden tool designed for homeowners and garden enthusiasts seeking an efficient and versatile solution for both blowing and vacuuming leaves and debris. This two-in-one unit combines the functionality of a leaf blower with that of a powerful vacuum, making it an ideal choice for maintaining a tidy outdoor space throughout the seasons.

One of the standout features of the MAC GBV 345 is its powerful 32cc two-stroke engine. This robust engine provides ample power to handle even the toughest tasks in your garden, ensuring that users can quickly and efficiently clear large areas of leaves and debris without experiencing fatigue. The lightweight design, weighing in at approximately 4.6 kg, allows for easy maneuverability, giving users the freedom to work without excessive strain.

The MAC GBV 345 is equipped with variable speed control, which enables users to adjust the blowing power according to specific requirements. This feature is particularly beneficial when working in delicate garden areas or around flowerbeds, allowing for precise control to avoid damaging fragile plants.

Switching between blowing and vacuuming functions is seamless, thanks to the innovative design that allows for easy conversion between modes.

This not only makes disposal easier but also allows for convenient composting of the shredded material.

Another notable feature is the ergonomic design, which includes an adjustable handle for enhanced comfort during use. The anti-vibration technology incorporated in the MAC GBV 345 significantly reduces user fatigue, allowing for longer operation times without discomfort.

Furthermore, the unit features a large-capacity collection bag with a 45-liter capacity, which is easily detachable, allowing for hassle-free emptying. This means that users can spend less time stopping to empty the bag and more time focusing on their yard work.
