Product details and specs

A classic petrol lawn mower, the Alpina AL4 46 SA offers powerful performance, robust build-quality and simplicity of operation, all at an undeniably attractive price-point!
Self-propelled through the rear wheels, the AL4 46 SA doesn’t need to be pushed – this makes it an excellent choice if your garden is on an incline, or has grassed areas too rough or bumpy to traverse with a hand-propelled model.
The AL4 46 SA is equipped with a 125cc STIGA engine, which you’ll find powerful, dependable and easy to start.
Single-lever cutting-height adjustment makes it quick and easy to select your preferred setting; while a robust steel cutter-deck means you can have absolute confidence in the durability of your purchase.
Made from lightweight, corrosion-resistant plastic, the grassbox on the AL4 46 SA holds a substantial 60 litres of clippings and benefits from a smart-grip handle that makes it quick and easy to fit and remove. A ‘collector full’ indicator lets you know when the box has reached capacity.
This 46cm machine carries a reassuringly lengthy two-year manufacturer’s warranty.
