Echo SRM-4000U

Not for the faint-hearted, this heavy-duty 42.7cc unit is big on power and gives an awesome performance. “This is the most fearsome thing I have ever used for trimming grass. It really is,” admits our tester. He likes it. We reckon Echo is onto a winner.
The SRM-4000U eats grass, but it’s not just for trimming. This unit comes as standard with a two-string cutting head and a steel brush blade. It’s not fitted with Echo’s ES Easy-Start system, nor with the i-start system, but the Pro-Fire electronic ignition and purge-pump carburettor make starting quick and easy.
Built to perform and to last, this two-stroke model has a commercial-duty air cleaner. The 8mm solid drive shaft is made from high-tensile steel. At the business end of the machine, the gearbox is designed to absorb punishment and gives an enviable smoothness of running. The debris shield is heavy-duty.
At 8.7kg the SRM-4000U is the heaviest machine in our test, but the balance of the unit and support afforded by the harness mean no one notices. The U-handle design is one of the best our testers have experienced and makes for easy movement in a scything action. It’s also easy to adjust, having a single thumbnut for speed. The grips are rubber coated and soft. We reckon this is a machine you won’t mind using for long periods of work. And with a one-litre fuel tank, it can run for long periods.
Our testers find the balance of the machine is perfect. It has an excellent cutting speed — yet you can’t feel any vibration (vector sum is 2.6m/s2) and the noise for the operator is not a problem. The controls are good — the on/off switch is very accessible. The quick release is very important, and it works so well you could literally drop the machine and run if needed.
It’s good, so does it come at a premium? No. At £399 ex VAT this is definitely value for money.
