What Stands Out

  • 15 inch cutting swath, wide enough that a fence line goes in one pass instead of two
  • Comes pre-wound with .095 in professional grade dual-twist line, so it cuts the first time you pick it up
  • Locks onto the EGO PH1400 and PH1420 power heads with the tool-free collar, no tools and no adapter
  • Costs a fraction of a standalone cordless trimmer because you already own the motor, shaft and battery
  • Hangs on a garage hook instead of taking floor space like a full trimmer

What To Check

  • Attachment only: there is no power head, no battery and no charger in the box, and it does nothing without a PH1400 or PH1420
  • Not compatible with EGO's standalone trimmers or with other brands' multi-head systems
  • A 15 inch swath on a big lot still means a lot of walking
  • Line is a consumable, so plan on buying spools

The STA1500 is the string trimmer head for EGO's Multi-Head System. It is a shaft section, a guard and a cutting head, and it turns a PH1420 power head into a 15 inch trimmer in about thirty seconds.

Read the box twice on this one. It is an attachment, not a tool. There is no motor, no battery and no charger here, and it will only mount to an EGO PH1400 or PH1420 power head. If you do not own one of those, this head is a stick in a box. If you do, the 56V ARC Lithium pack from your mower kit or blower kit already powers it.

The Numbers That Matter

15 inch cutting swath. That is the wide end of the residential range. A fence line, a mailbox post or the strip along a retaining wall goes in a single pass rather than two overlapping ones.

.095 in dual-twist line. Line diameter is the spec that decides what you can cut. At .095 in this is in professional territory, which means it holds up against thick stems and chain link instead of shredding on the first fence post.

Two compatible power heads. PH1400 and PH1420. That is the whole list. It is the single most common mistake on multi-head purchases, so check the model number stamped on your power head before you order.

Who It Is For

The dad who bought into the Multi-Head System and wants the edges to look like the mow. It is the first attachment most people add, and the EA0800 edger attachment is usually the second. All of it runs on the BA2800T 56V 5.0Ah battery shared with the LM2135SP mower and the LB6504 blower. For the hand trimming a string head cannot reach, the Fiskars bypass pruners finish the beds.

The Short Version

If the PH1420 power head is already in the garage, this is the attachment most people add first, because trimming is the job a mower cannot do. Confirm you own a compatible power head and a 56V battery before you order, since this head is not a tool on its own.
