Our take
A Pro X trimmer built around a front-mounted direct-drive motor, which shifts the weight forward and cuts vibration noticeably compared with rear-motor designs. The carbon fibre shaft keeps it to 3kg despite a 42cm cutting swath, and three speeds (4000/5000/6000rpm) let you trade power against runtime. Bare tool.

Part of the PRO X range, this new model introduces a front-mounted motor, improving efficiency by delivering power directly to the cutting head without a drive shaft. The result is reduced weight, lower vibration, and exceptional balance in use.With a 42cm cutting width and Rapid Reload head fitted with 2.4mm twist line, the STX4200 makes light work of overgrown grass and weeds. The 3-speed LED interface with handle-mounted control allows instant adjustment to match the task at hand.Built tough yet lightweight, the carbon fibre shaft provides maximum durability without unnecessary weight, making long trimming sessions more comfortable.
