Single-sided blade hedgetrimmers like this superb example from Echo are the preferred configuration for professional use because of their longer blades and wider cutting-arcs; better cut-to-weight ratio; dual piston-ring engines; and optimised anti-vibration systems. This is the industry-standard professional hedgetrimmer, long famous for its balance, efficiency and superior durability. It has a 21.2cc two-stroke engine, weighs just 4.7kg and has an expansive 59cm blade for increased productivity. Equipped with a 0.39-litre fuel-tank, the HCS-2810ES has a gear reduction ratio of 5.13.

Designed and built in Germany to exacting standards, the STIHL HS87 R has been developed for the fast and efficient trimming and shaping of substantial hedges. Its top-quality Stihl 2-Mix engine powers a pair of lengthy 75cm single-sided blades with an unusually wide 38mm tooth-gap that ensures a clean cut in large-diameter growth; while its comprehensive vibration-damping measures and low-weight construction work to minimise operator-fatigue. From-cold starting is ultra-reliable, thanks to a manual fuel-pump. Weighs 5.5kg.

Single-sided hedgetrimmers like this fine example from Stihl are favoured by landscape professionals thanks to their extra-long blades and the resulting high productivity-rate. The 75cm cutter-bar on the STIHL HS86 T-30 operates at a rapid 5000rpm and has a 38mm tooth-spacing; a combination that ensures a fast, bruise-free cut in thicker growth; while the 22.7cc engine boasts an electronic ignition and a manual fuel-pump for trouble-free starts at each time of asking. Vibrations to the handles are reduced by an efficient spring-type damping system, thereby reducing stress and strain on the operator’s body.
