Gardena RotorCut or nylon line: which head suits your edge?
Updated: October 2026
Choosing Gardena RotorCut or nylon line comes down to what the head will meet after the mower has passed. Plastic blades are simple on a soft, regularly maintained edge, but paving can consume them quickly. A 2 mm line is the more relevant option for denser grass, although the PowerTrim listing in this comparison has an unresolved cutting-width cell and a small rating pool. This page focuses on the head; use our [Gardena grass trimmer comparison](/hub/lawn-and-garden-equipment/gardena-grass-trimmer) for box contents and saved UK prices.

Which head each listing actually has
SmallCut 23/18V, ASIN B0BNLNVYFL, and ComfortCut 23/18V, ASIN B08HS1RWFG, use Gardena's RotorCut system. Each saved listing includes five plastic blades and a 230 mm cutting width at a listed 9,000 rpm. You replace a worn blade with the click-in spare for the article. PowerTrim 30/18V, ASIN B0DMF62LG2, is the clear line model. Its bullets specify a 2 mm nylon line and PowerBoost. EasyTrim 25/18V, ASIN B0DMF7Q6SN, is described as a line tool in reviews, but Amazon does not give a diameter. One EasyTrim buyer had ordered plastic strips by mistake. Do not buy RotorCut blades for PowerTrim or a line refill for SmallCut. SmallCut and ComfortCut are body-only. PowerTrim and EasyTrim include a PBA 18V/36 battery and charger. The Gardena buying guide covers that box decision.
What RotorCut is good at, and where it wears
RotorCut suits short finishing work after mowing. There is no spool to wind, and you replace a blade with the battery removed. On soil, a bed or a gap from timber, the head can clip grass without spending the session on an abrasive surface. A UK SmallCut review reports about one blade per cut beside a concrete path. ComfortCut feedback describes blades shortening on edging stones, and one review mentions a cracked blade carrier. These are owner reports, not a measured lifespan. An Expert Reviews test of a different Gardena EasyCut found blades used up in a session against stone, brick or thick weeds. That tool is not SmallCut or ComfortCut. Keep the blade on the grass side. Five included blades are consumables, not five seasons of supply. Our how-to guide covers replacement and edging.
The 2 mm line, and the cell that says 2 mm
PowerTrim is the model for thicker grass when you want a stated 2 mm nylon line and the named PowerBoost. Reviewers mention the feed. Line is not indestructible: masonry still wastes material and can damage the head. The difficult specification is width. This Amazon cutting-width cell says 2 mm, the same figure as the line thickness. The model name is PowerTrim 30, and Gardena UK publishes 30 cm for solo article 14703-55. This kit is article 14703-20, so that solo width is not copied into the cell. Ask the seller or Gardena if swathe width decides the purchase. The 4.9 average rests on 18 ratings, fewer than the roughly 100 behind either RotorCut body. About £143.64 includes a battery and charger. EasyTrim gives a 25.8 cm width plus an edging button and wheel, but Amazon does not state line diameter or feed type. Buy a refill only after you identify article 14704-20.
Which should you buy?
Choose RotorCut for light grass around an already-mown lawn if you can keep the head off brick, concrete and stone. SmallCut is the lower-priced, 1.6 kg listed body. ComfortCut adds telescopic and edging wording. Neither saved box includes a POWER FOR ALL pack. Choose the PowerTrim kit when the grass is denser, you want the listed 2 mm line and PowerBoost, and you need the battery and charger in the box. Accept the unresolved width cell and the 18 ratings behind the 4.9. If guided edging matters more than a named 2 mm line, EasyTrim's button and wheel are the alternative, once you confirm its consumable. Neither head is for woody growth.

Common questions
Do RotorCut blades last?
There is no reliable lifespan that applies to every garden. They can last much better on soft edges when kept away from hard surfaces, while owner reports describe rapid shortening on concrete and edging stones. Inspect the blade before use and replace it according to the manual rather than relying on a number of weeks.
What happens if a blade hits the path?
The plastic edge can wear down quickly, chip or put extra load on the carrier. Stop, remove the battery and inspect both blade and head if the impact changes the sound or vibration. Position the cutter on the grass side rather than using paving as a physical guide.
Is nylon line better for thick grass?
PowerTrim’s stated 2 mm line and PowerBoost make it the more relevant product here for denser grass. That does not turn it into a brush cutter for woody stems, and the line still wears against masonry. Use a more suitable tool or professional help where growth repeatedly stalls the head.
What is the PowerTrim cutting width?
The Amazon cell for ASIN B0DMF62LG2 says 2 mm, which matches the line diameter rather than a plausible swathe. Gardena states 30 cm for a different solo article, 14703-55. We cannot transfer that figure to kit article 14703-20 without confirmation, so the listing remains unresolved.
Can I put RotorCut blades on the PowerTrim?
Not on the evidence available. PowerTrim is listed with a 2 mm line, while RotorCut blades belong to compatible blade heads. Do not improvise a conversion or buy spares merely because they carry the Gardena name; use only consumables and assemblies approved for the exact article.
What line does the EasyTrim use?
Reviews describe line, but the saved Amazon listing for EasyTrim article 14704-20 does not state its diameter or feed mechanism. Check the manual or Gardena’s official spare-part information for that article before buying a refill. Do not assume a solo model’s specification automatically applies to the kit.
