Quick verdict
A 25cc two-cycle curved-shaft trimmer whose selling point is a push-button electric start that LawnMaster rates for up to 150 starts per charge, plus a 17-inch swath, a 420 mL tank, a dual-line bump head with 0.080-inch line and a split shaft for attachments. It suits anyone who wants gas runtime but cannot or will not yank a cord. The caveat is the stated 16.5 pounds, which is heavy for a curved-shaft trimmer if that is the tool weight.

Who this trimmer is for
The pull cord is the reason many people give up on gas trimmers, and shoulder or wrist trouble makes it a real barrier rather than an annoyance. The LawnMaster 25cc trimmer replaces the cord with a push button and a small starter battery that the maker rates for up to 150 starts per charge. Around that it is a conventional homeowner trimmer: 25cc two-cycle engine, 17-inch swath, curved shaft, dual-line bump head and a split shaft for attachments.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
LawnMaster states a 25cc two-cycle engine, a 420 mL fuel tank, a 17-inch cutting width, a dual-line bump-feed head loaded with 0.080-inch line, an adjustable assist handle, a curved shaft with a split-shaft coupler for attachments, and a stated weight of 16.5 pounds. How the starter battery is charged, whether by a plug-in charger or by the engine while running, is not spelled out in the listing, and neither is the list of compatible attachments. Both belong in the manual, and both are worth checking before you buy.
Cutting and the bump head
A 25cc engine on a 17-inch swath is a standard homeowner pairing and handles weekly grass, bed edges and a fence line without complaint. The 0.080-inch line is the limiting factor: it cuts grass cleanly but wears fast against concrete, brick and chain link, and it shreds in woody stems. Owners of trimmers with this line size generally report frequent bumping along hard edges. If the head accepts it, stepping up to 0.095 line is the usual fix, but confirm the head’s rated diameter in the manual first.
Starting and fuel
The electric start is the reason to buy this trimmer. Press the button, the engine turns over, and the choke and primer routine is the same as any two-cycle engine minus the cord. Up to 150 starts per charge means the starter battery is not something you think about weekly. The 420 mL tank is about 14 ounces, which is on the larger side for a curved-shaft trimmer and gives a long session before refueling. Mixed fuel, a seasonal spark plug and a clean air filter are the ongoing chores, as with any two-cycle machine.
Build, handling and ergonomics
The adjustable assist handle and curved shaft put the head close to the body, which is comfortable around planters and posts. The weight is the question mark. LawnMaster states 16.5 pounds; if that is the tool rather than the shipping weight, it is noticeably heavier than typical 25cc curved-shaft trimmers, and the starter motor and battery would explain some of it. Owners of electric-start gas tools generally accept the extra weight as the cost of the button, but a long session will be felt in the arms.
Living with it
Keep the starter battery topped up per the manual so the button works when you need it; a two-cycle engine with a flat starter battery and no cord is a paperweight until it is charged. Run fresh mixed fuel and drain or stabilize it before winter. Keep spare 0.080 line on hand. LawnMaster’s warranty terms are on the product page and should be read, and parts support for the brand is thinner than for Husqvarna, Echo or Stihl.
Alternatives to Consider
The Husqvarna 122C is a lighter 22cc curved-shaft trimmer with Smart Start and a pull cord that owners find easy. The Ryobi 25cc 2-cycle attachment-capable trimmer with the optional Easy Start plug-in starter is the main rival for push-button convenience on gas. If starting effort is the whole problem, the EGO Power+ ST1511T removes the engine entirely and starts with a trigger.
Verdict
Buy the LawnMaster 25cc electric-start trimmer if a pull cord is the one thing keeping you off gas, you want a 17-inch swath and a big tank, and you can live with a heavier tool. Skip it if weight matters more than the button, if you trim a lot of concrete edges where 0.080 line struggles, or if you want a brand with a dealer on every corner.

LawnMaster 25cc 2-Cycle Gas String Trimmer with No-Pull Electric Start, 17-Inch Curved Shaft FAQs
A small onboard battery turns the engine over when you press the button, so there is no pull cord to yank. LawnMaster rates it for up to 150 starts per charge; the listing does not say how the starter battery is recharged, so check the manual.
LawnMaster states 0.080-inch line in a dual-line bump-feed head. That is a light-duty diameter that cuts grass cleanly but wears quickly against concrete and fences.
Yes. The shaft splits at a coupler so LawnMaster attachments can be fitted. The listing does not name which ones or claim compatibility with other brands, so check LawnMaster's range before buying for that purpose.
That is the figure in the listing. It may be a shipping weight; if it is the tool weight, it is several pounds heavier than typical 25cc curved-shaft trimmers, which usually land near 11 to 13 pounds.
