Greenworks offer emission free solutions to yard maintenance tasks and the Greenworks 21602 is just part of their growing product range. It's not the cheapest model available, but comes with a bunch of features designed to make the sometimes tedious task of keeping your yard tidy a little bit easier. When selecting a Greenworks product you'll never have to worry about nasty oil spills, fuel storage or winter preparation for your string trimmer again.
If you are looking to go cordless with your new trimmer, but are not convinced by the cheaper models that use NiCad batteries then the Greenworks 21602 may well be worth a look. It uses lithium-ion batteries which offer a number of advantages over their NiCad counterparts. You will always have to charge NiCad batteries for the full duration (typically 12 hours), whereas lithium-ion batteries don't have to be totally discharged before recharging. If the battery still had a 50% charge, you would only have to charge it for 50% of the full duration (3-4 hours) to top it up. The run time they offer is always superior to NiCad models too.
Here are the Benefits of the Greenworks 21602 String Trimmer:
- In terms of the power and runtime it provides, the 20 volt lithium-ion battery that is used in the Greenworks 21602 is far superior to many of its competitors. It charges quicker (it can be fully charged within 3-4 hours) and it lasts for a decent length of time, with many users reporting runtimes of 45-60 minutes. This allows you to cover a decent sized area on a single charge and minimizes your waiting time in between charges. Greenworks have also incorporated a simple push button that allows you to see how much charge you have remaining, which is very handy if you have a particularly large area to take care of.
- It doesn’t have the available power of a gas trimmer, but the cutting performance the Greenworks 21602 produces isn’t that inferior. In fact it offers enough power to be able to cut through thicker varieties of grass and weeds, which is reassuring if you do sometimes skip your yard maintenance duties (we are all guilty of this once in a while!) for a few weeks.
- The majority of models available nowadays come with an automatic line advancement feature and this one is no different – although each manufacturer seems to have a slightly different method of dispensing the line. Some use a bump system, while others simply use centrifugal force. On this one, line (1/4″) is automatically fed out each time you press the starter trigger and fire the trimmer up. This offers certain advantages over other systems, the main one being that you are in control of how much line is dispensed, allowing you to make the line last longer. The free extra spool of line you get with this trimmer is a nice touch too.
- This trimmer can also be used as an edger and it works well in this capacity. Converting it to an edger is straightforward; you simply push a button which allows you to rotate the cutting head. Whilst it doesn’t have an edge guide, there is a little wheel built into the cutting head that supports some of the weight when you’re edging and rolls nice and smoothly along your pathways. You have a good clear view of the cut too, which allows you to maintain a straight line.
Here are the Reported Disadvantages of the Greenworks 21602:
- The air vents that have been incorporated into the design can get blocked up if you’re not careful, which can cause the motor to seriously overheat and potentially cause irreparable damage to the unit. Watch out for this and make sure you clean this down if you notice the vents getting blocked up.
- Some users have reported problems relating to battery longevity. After using the trimmer for a number of months, the battery’s ability to hold a charge reduces significantly. It must be stressed that only some users have experienced this problem.
