STIHL HSA 50 20″ Cordless Hedge Trimmer (Tool Only)

Why buy the STIHL HSA 50 20″ Cordless Hedge Trimmer (Tool Only)? Lightweight design at just 2.9kg (tool body) for comfortable, low-fatigue use. Laser-cut, diamond-ground 20-inch blades for a precise and exceptionally clean finish. Quiet cordless operation, perfect for maintaining hedges in noise-sensitive residential areas. Part of the versatile STIHL AK battery system (battery & charger sold separately). Teardrop-shaped blades grip branches effectively for a more efficient cut. Includes a screw-on tip protector to prevent blade wear when working near walls or the ground. Efficient and Precise Cutting for Domestic Gardens The STIHL HSA 50 is a battery-powered hedge trimmer designed specifically for homeowners looking to maintain bushes, shrubs, and medium-sized hedges. Its incredibly low weight of just 2.9 kg makes it easy to handle, while the quiet 36V motor ensures it can be used in residential areas without causing a disturbance. This model is ideal for those who value performance, comfort, and low noise levels for their garden tasks. Engineered for a superior finish, the HSA 50 features laser-cut, double-edged, diamond-ground blades. This advanced cutting system produces a remarkably clean cut. The blades also incorporate a unique droplet shape that effectively guides twigs and branches into the cutting teeth, ensuring a consistent and efficient trim. A universal pruning system with generous 30mm tooth spacing allows the trimmer to handle both fine trimming and light pruning tasks with ease. Designed for Comfort and Durability STIHL has designed the HSA 50 with user comfort and tool longevity in mind. The ergonomically shaped control and loop handle, combined with the balanced weight distribution when using the recommended AK 10 battery, reduces user fatigue. The two-handed control design is suitable for both right and left-handed operators, starting easily by pressing the switches on both handles simultaneously. To protect the blades from damage when working close to the ground or along walls, a screw-on tip protector is included. The engine casing’s smooth surfaces prevent it from snagging on branches and make it simple to clean after use. For convenient and safe storage, the handle features an integrated hanging eyelet. STIHL AK Battery System Performance As part of the STIHL AK System, the HSA 50 offers cordless freedom and is compatible with a range of batteries to suit the task at hand. This unit is sold as a ‘Tool Only’ body, meaning the battery and charger must be purchased separately. This is ideal for users who already own other tools from the STIHL AK range.

Frequently Asked Questions Frequently Asked Questions What battery and charger do I need for the STIHL HSA 50? The STIHL HSA 50 is part of the AK System. It is compatible with the AK 10, AK 20, and AK 30 batteries. The recommended battery for the best balance and performance is the AK 10. You will also need a compatible charger, such as the AL 101 standard charger. This product is sold as ‘Tool Only’, so the battery and charger must be purchased separately. How long does the battery last on the HSA 50 hedge trimmer? The battery working time depends on the battery used. With the recommended AK 10, you can expect up to 50 minutes of runtime. This increases to 100 minutes with an AK 20, and up to 130 minutes with an AK 30 battery. Please note these are maximum times and can vary with cutting conditions. Is the STIHL HSA 50 suitable for large, tough hedges? The HSA 50 is primarily designed for trimming bushes, shrubs, and medium-sized domestic hedges. Its 30mm tooth spacing allows it to handle branches of a reasonable thickness, but for very large, dense, or overgrown hedges, a more powerful model from STIHL’s professional range may be more suitable. Does this hedge trimmer come ready to use? This is a ‘Tool Only’ model, so you will need to supply your own battery and charger from the STIHL AK system. When purchased from an authorised dealer like Sims Garden Machinery, you have the assurance of genuine product support. For our local customers, we also offer a free Pre-Delivery Inspection (PDI) and handover service to ensure the machine is fully assembled and you’re confident in using it.
