One of the down sides of using a Weed Whacker, String Trimmer or a Weed Eater is not being able to tell At-A-Glance if you have enough trimmer line inside the spool. The only way you can do that in an Echo Trimmer is by physically removing the spool cover and that becomes a nuisance as many people forget to. When you go property to property time is of the essence, and when we arrive at a job site we wanna grab the weed eater and start trimming the grass to finish on time. But a few minutes later you tap the trimmer for more string and it comes flying out. Now you don’t have string line and you gotta walk back to the truck or trailer to get dome more thus slowing you down and wasting productivity time.. Now this can be prevented by doing an At-A-Glance hack on all your weed eaters and you won’t go through that again! And you won’t be carrying that extra wounded up string line in your pocket all day either. Simply make two holes on either side of the spool casing and see inside At-A-Glance! This hack works on any weed eater that has a string line spool casing or head that you could drill one or two holes in it without causing damage or weakening the integrity of the casing. This hack is perfect for the Echo SRM225 , the Echo SRM2620 snd many more. Hopefully this hack can help you save time and be more efficient in the field!
