A 21.7 cc double-sided petrol hedge trimmer with a 75 cm cutter bar and high-torque gear designed to handle dense, overgrown hedges. The slim, balanced design, multi-position rear handle and low weight give good control in extended use while low vibration levels and high-speed professional blades deliver efficient, consistent cuts.
Tackles dense growth
High-torque gearing combined with coarse-cut, high-capacity blades handles thicker and overgrown material. Teeth opening is 30.5 mm, so it manages substantial branch diameter compared with finer hedge tools.
Long cutter for fewer passes
75 cm cutter bar covers more hedge in a single pass, improving job speed and reducing time spent repositioning on long runs.
Comfortable, controllable handling
Multi-position rear handle and a slim, balanced layout reduce strain during extended use. The unit weight (excl. cutting equipment) is 5.2 kg and equivalent vibration levels are low (front 2.1 m/s², rear 2.2 m/s²), making it easier to control on vertical and horizontal cuts.

FAQs
Will this fit my machine?
Fitment can vary by model and deck size. Send us your mower model (and deck size if applicable) and we’ll confirm compatibility before you order.
Do I need any extra brackets or fitting kits?
Some accessories require a mounting kit or specific brackets depending on your machine. If you’re unsure, ask us and we’ll advise the correct setup.
Can you fit it for me?
Yes — if you’d like installation, let us know when ordering and we can arrange fitting (collection, workshop fit, or on-site depending on the product).
How should I start the 522HDR75X?
Use the air purge to remove air from the carburettor and fuel system before starting, set the intuitive choke as required and use the stop switch (it auto-returns to ON). Follow the detailed starting sequence in the supplied manual for best results.
What size branches can it cut?
The 75 cm double-sided cutter with 30.5 mm teeth opening and high-torque gear is intended for dense hedging and thicker shoots—suitable for substantial, overgrown material and larger-diameter stems up to the blade capacity.
What PPE and maintenance should I plan for?
Wear hearing protection (sound pressure 93 dB(A), guaranteed sound power 102 dB(A)), eye protection, gloves and sturdy footwear. Regularly inspect and sharpen the blades, keep the two-stage air filter clean, check spark plug condition (NGK CMR6A specified) and follow the service schedule in the manual. For gearbox or major service work, use an authorised Husqvarna service centre.
