Some manufactures offer versatile 3-in-1 Grass Trimmers/Edgers/Mini Mowers or different combo kits which are designed to tackle multiple lawn tasks.

Advantages of multifunctional cordless string trimmers
With regard to the above mentioned summary of the advanced versatile models offered as a single tool or in a kit, you can realize that there is a broad selection of worthy products on the current market. In particular, such tools are designed to unite functions of different lawn equipment. A 3-in-1 model features a pivoting head to convert it from a string trimmer to an edger.
Some models also come with a detachable wheeled-base which serves as a support when using a grass edger. Also, the base can be used to insert a trimmer into it, thus converting a tool into a mini-mower. The latter will ensure a desired height of a line on one level while cutting; thus, achieving a perfectly manicured lawn. In general, with the help of one tool you will be able to perform a preliminary cutting of weeds in a trimming mode; then, you can use a wheeled-base to perform edging of a grass and a finishing cutting of your lawn.
Features to be considered when looking for a multifunctional cordless string trimmer | Buyers’ Guide
Despite different functionalities of various models, there are certain basic features which have to be obligatory taken into account when looking for a worthy lawn tool.
Power output. This parameter is determined by a rated voltage of a battery. This value influences on the performance of a cordless unit. However, even the most powerful cordless string trimmer is not suitable for cutting of grass with tough stems. So, you should carefully assess the capacity of a unit and correlate it with your landscaping needs in advance. For instance, BLACK+DECKER is equipped with a 40V li-ion battery which generates enough power to deal with various gardening chores.
Cutter. The majority of cordless models are equipped with a nylon string. Such cutting means is less exposed to damage caused by stones or any other solid objects on your territory. Nevertheless, this material would not cope with tougher weeds. In this case, look for an option with a line of a bigger diameter or one offered with a dual line for additional strength. The Greenworks G-MAX 40V Cordless String Trimmer features 0.065 dual line which improves its reliability even for more challenging cutting tasks. More powerful battery-powered units feature plastic blades (can be an additional option). However this variant seems to be a kind of controversial issue. Such cutter blades can be easily deteriorated when striking against other items than grass. It might cause vibration and disturbance of balance of a tool. Thus, it becomes a risk for a user’s safety, as well as for integrity of internal parts of a motor.
Maximum line diameter. It is another performance indicator of a string trimmer: the higher this value is the thicker stems will be handled. The standard diameter of a line varies from 0.047-inch up to 0.157-inch. The choice of a particular size will directly depend on a type of work you are going to fulfill on your area. For instance, the Makita XRU15PT1 with its 0.080-inch line is capable of covering larger swath and cutting tougher weeds. However, you should always remember that a rated diameter recommended by a manufacturer mustn’t be exceeded. Otherwise, you may damage a tool!
Speed. This parameter is measured in rotations per minute (RPM). Cordless string trimmers feature lower speed in comparison with gas-powered counterparts. However, the cutting edge battery-powered models equipped with a brushless motor and advanced transmission systems allow reaching comparatively high speed rates. In particular, they are capable of attaining 6500 RPM and higher for maintaining larger spaces effectively. BLACK+DECKER (LST136) 40V Max String Trimmer / Edger is capable of deliver up to 8500 RPM and vary this value by a Power Command function.
Battery capacity. Li-ion battery (common type used for power tools) capacity determines its life till next recharging. This parameter typically amounts to 1,3 Ah up to 4,5 Ah. Nowadays, some battery units can be continuously operated up to 45 minutes. However, an increased battery capacity definitely contributes to a longer runtime of a string trimmer, but makes it heavier. Thus, many manufacturers offer such batteries as an option. And the Worx WG170.3 features a 4Ah battery, one of the highest in its class.
Battery voltage. This parameter directly influences on power output and performance of a cordless string trimmer. Thus, a unit will be capable of performing more challenging cutting if it is fitted with a high voltage battery. The value may vary within 14,4V – 40V range.
Weight. This feature will be highly relevant until you attach a wheel-base to your battery string trimmer. In other cases, you will have to hold it in your hands. And even the most popular models can be inconvenient in use due to heavy weight and cumbersome design. Thus, choosing a model below 6 lbs will facilitate its handling significantly. Like the WORX WG163 with a weight of 5.3 lbs (together with a battery) which commits to be highly convenient and effortless in use for any user.
