Our take on the Ryobi 40V 15 in. Expand-It Cordless Battery Attachment Capable String Trimmer

The Ryobi 40V 15 in. Expand-It is a cordless straight-shaft string trimmer built on Ryobi's 40V battery platform. Its split shaft accepts the Expand-It attachments, so one power unit can run a trimmer, edger, blower or pole saw. The bump-feed REEL EASY+ head and adjustable 13 to 15 in. cutting width suit routine yard work on a suburban lot. It is heavier than many 40V rivals at 8.6 lb, and reviewers often note that the battery and charger are not included, so the real value depends on whether you already own Ryobi 40V packs.

Best forHomeowners already on the Ryobi 40V battery platformBuyers who want one power head for several yard toolsTrimming and edging a typical suburban yardShoppers who prefer a straight shaft for reach under fences and decks
Pros
  • Expand-It split shaft takes Ryobi's edger, blower, pole saw and other attachments
  • Adjustable 13 to 15 in. cutting width lets you trade reach for runtime
  • REEL EASY+ bump head speeds up line reloads
  • Straight 44 in. shaft reaches under shrubs and along fences
  • Runs about an hour on a 40V 4Ah pack
  • Shares batteries with the rest of Ryobi's 40V lineup
Cons
  • Battery and charger are not included in the base tool
  • 8.6 lb is heavy for a 15 in. trimmer, especially with a 4Ah pack
  • Only 0.080 in. line, which is thin for thick weeds
  • Fixed shaft, so no telescoping adjustment for taller users
  • Mixed owner reports on durability and the bump head

What reviewers say

  • 3.7 / 5314 ratings

Ratings sit around 3.7 out of 5, and owners split between those who like the attachment system and light trimming and those who hit reliability or power limits. Complaints cluster on the bump head, the weight and durability.

What people mention
  • Attachment systemPraisedOwners like that the split shaft takes other Expand-It tools, so one power unit covers several jobs.
  • Bump headCriticisedReviewers say the bump feed jams or stops feeding line, and reloads are not always as easy as claimed.
  • WeightCriticisedAt 8.6 lb with a battery fitted, owners find it tiring to carry for long trimming sessions.
  • DurabilityCriticisedSome owners report motor or shaft failures within a season or two of regular use.
  • PowerMixedFine for grass and light weeds, but owners say it bogs down in thick brush and tall growth.
  • RuntimePraisedOwners get roughly an hour of light trimming from a 40V 4Ah battery.

Questions and answers

Does the Ryobi 40V trimmer come with a battery and charger?
No. The base tool ships as a bare tool, so you need a Ryobi 40V battery and charger, sold separately, unless you already own them.
What attachments fit the Expand-It shaft?
It accepts Ryobi Expand-It attachments, including edgers, blowers, pole saws, hedge trimmers and cultivators. Check that each attachment is rated for 40V.
How long does the battery last?
Ryobi rates about one hour of runtime on a 40V 4Ah battery. Heavier grass and thicker weeds cut that figure.
Is it good for thick weeds and brush?
Not really. It uses 0.080 in. line and owners report it bogs down in heavy growth. It suits grass, edges and light weeds.
Can I adjust the cutting width?
Yes. The guard adjusts the cut from 13 to 15 in., so you can narrow it for tighter spots or widen it for open lawn.
Is the shaft adjustable for height?
No. The 44 in. straight shaft is fixed, so taller users cannot extend it.
Where is the Ryobi 40V 15 in. Expand-It Cordless Battery Attachment Capable String Trimmer cheapest?
At eBay, for $50.00, 58% under what the other stores charge, as of our latest check.
