The Ryobi RY40HPST02K is the complete kit version of the 40V HP brushless 17 in. string trimmer — Ryobi's heaviest-duty cordless trimmer in the 40V HP lineup — bundled with a 4.0 Ah 40V HP battery and charger for immediate use. Rated as an equivalent to a 32cc gas trimmer, the 40V HP brushless motor handles thick grass, tall weeds, and demanding edging tasks with sustained power delivery throughout the battery charge. The 17 in. cut width covers more ground per pass compared to the 16 in. RY40HPST01K, reducing overall trimming time on large properties. Whisper Series design, REEL EASY+ 3-in-1 head, and EXPAND-IT attachment capability complete the feature set for users transitioning from gas or building out a 40V HP outdoor tool system.
What is included in the RY40HPST02K kit?
The RY40HPST02K includes the 40V HP Brushless 17 in. String Trimmer, one REEL EASY+ 3-in-1 Bump Feed Head, one 40V HP 4.0 Ah battery, and one 40V charger. It is a complete, ready-to-use package requiring no additional accessories to begin operation.
Should I choose the RY40HPST02K or the RY40HPST01K?
The RY40HPST02K offers a 17 in. cut width and 32cc gas-equivalent power — better suited to larger properties, thick or tall grass, and heavy-duty trimming. The RY40HPST01K has a 16 in. cut width and is appropriate for most standard residential lots. If your yard is large or frequently overgrown, the RY40HPST02K is the better investment; for average suburban yards, the RY40HPST01K is sufficient.
Will the 4.0 Ah battery be enough for a large property?
The included 4.0 Ah 40V HP battery provides solid runtime for most residential trimming sessions. For larger properties or back-to-back jobs, Ryobi sells higher-capacity 40V HP batteries — such as the 6.0 Ah and 8.0 Ah — separately. Having a second battery on hand and charging one while using the other is a practical approach for extended trimming work.
Why is the assembled weight listed as null for the RY40HPST02K kit?
The confirmed tool-only weight of the RY40HPST02B is 9.25 lbs. The total assembled weight of the RY40HPST02K kit — with the 4.0 Ah battery installed — has not been independently confirmed for this listing. The bare tool weight of 9.25 lbs (from the RY40HPST02B spec) is the best available reference point.
Is the RY40HPST02K a good replacement for a gas trimmer?
Yes — Ryobi rates the RY40HPST02K as equivalent in performance to a 32cc gas string trimmer, which covers the majority of residential and light commercial trimming tasks. It eliminates the costs and maintenance associated with gas equipment (fuel mixing, carburetor service, air filters, spark plugs) and operates at significantly lower noise levels, making the transition from gas to battery a practical upgrade for most homeowners.
