Practical, lightweight petrol hedge trimmer for domestic use. The 122HD45 combines Smart Start® and an air purge for easier starting, LowVib® dampening to reduce vibration, and a low-noise engine design. Suitable for routine trimming of small to medium hedges where comfortable, relatively quiet operation matters. Easy starting Smart Start® engine and starter design reduce resistance in the starter cord, and the air purge removes air from the fuel system for quicker, less strenuous starts. Comfortable operation LowVib® dampeners lower vibration transmitted to your hands and arms, and the unit’s light weight (4.6–4.7 kg depending on measure) makes it easier to handle for longer periods. Low-noise design The engine is designed to run more quietly than typical petrol models, helping reduce disturbance to neighbours while you work.

Quick Start with Air Purge Air purge removes air from carburetor and fuel system for easy starting Features 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 do I start the 122HD45? Set the stop switch to ON (it auto-resets), use the air purge to remove air from the carburettor/fuel system, then pull the starter. Smart Start® reduces starter cord resistance so starting requires less effort. Refer to the user manual for full starting and choke instructions. What size cutting blade and cutting capacity does it have? The 122HD45 has a 45 cm knife length with a 28 mm teeth opening and a cutting speed of 4,050 cuts/min — suitable for trimming small to medium branches and shaping hedges. How loud and how much vibration should I expect? Sound pressure at the operator’s ear is rated at 93 dB(A) and guaranteed sound power level (LWA) is 101 dB(A). Vibration levels are reduced by LowVib®; equivalent vibration values are approximately 2.9 m/s² (front handle) and 4.9 m/s² (rear handle). Use hearing protection and gloves, and follow local guidance on permitted working hours to limit disturbance.
