Craftsman 316711021 gas trimmer Parts

For the Craftsman 316711021 gas trimmer, .095 trimmer line is the better all-around choice for most yards because it lasts longer and cuts thicker weeds with fewer breaks. .080 line is better when you want lighter, more precise trimming and you are mostly cutting grass.

Quick comparison: .080 vs .095

Line size	Best for	Pros	Trade-offs
.080 in	Light-duty trimming and edging	Easier to feed, cleaner edging, less engine load	Breaks faster in thick weeds, slower on heavy growth
.095 in	General use and tougher weeds	More durable, faster cutting in dense growth	Uses more power, can be harder to load in some heads

How to choose the right line for your job

• Choose .095 if you regularly hit thick weeds, fence lines, or rocky edges.
• Choose .080 if you mainly edge sidewalks and trim light grass.
• If the trimmer bogs down with thicker line, step down to .080.
• If the line keeps snapping or wearing down quickly, step up to .095.
• Match the line to what your cutting head is designed to accept; check the 316711021 owner's manual for the recommended diameter range.

Tips to get better performance (either size)

• Keep the cutting line length correct; too long overloads the engine and clutch.
• Tap-feed only as needed; over-feeding wastes line and reduces RPM.
• Replace worn line with fresh line; old line gets brittle and breaks more.
• If you are reloading, use a quality replacement such as mtd line trimmer cutting line 753-06767 when it matches your head requirements.

Why it matters

Line diameter affects cutting speed, durability, and how hard the engine works. On a gas trimmer like the Craftsman 316711021, .095 usually delivers the best balance of power and line life, while .080 is ideal when precision matters more than toughness.

Yes, you can often use .095-inch trimmer line on the Craftsman 316711021 gas trimmer if the cutting head is rated for it; .095 line is thicker and typically holds up better in heavy weeds, but it can reduce runtime and make the head feed less smoothly if the head was designed for thinner line. Check the 316711021 owner's manual for the exact line diameter range.

Quick fit check (before you buy)

• Confirm the cutting head lists .095-inch as an approved diameter.
• If your head is a bump-feed style, thicker line can jam if it is overfilled.
• Use round line for easiest feeding; twisted or square line can be harder to advance.
• If the engine bogs down in normal trimming, step down to a thinner diameter.
• Replace brittle or fused line; old line feeds poorly regardless of size.

What changes when you move up to .095 line?

Line diameter	Best for	Tradeoffs
.065 to .080	Light grass, edging	Less durability in thick weeds
.095	Mixed grass and weeds	More load on engine, can feed slower
.105+	Heavy brush (only if head allows)	Higher chance of bogging and poor feed

How to load .095 line so it feeds correctly

1. Cut two equal lengths (or one length for a single-line head).
2. Wind in the direction shown on the head arrows.
3. Keep wraps tight and even; do not cross layers.
4. Do not overfill; leave enough room for the line to move.

Why it matters

Using the correct diameter helps the cutting head advance line reliably and keeps the engine from running overloaded, which improves trimming performance and reduces wear on the clutch and drive components.

Yes, many TrimmerPlus attachments work with Craftsman powerheads, including the Craftsman 316711021, as long as the trimmer has a compatible attachment-capable coupler (often called a split-boom or universal attachment coupler). Confirm the coupler style and connection method in your 316711021 owner's manual.

How to confirm compatibility on your Craftsman 316711021

Check these items before buying an edger, cultivator, or blower attachment:

• Coupler type: Attachment-capable couplers typically have a clamp/knob and a release button or pin.
• Shaft style: Many systems use a square drive shaft inside the tube; some use other profiles.
• Tube diameter and length: The attachment tube must seat fully and clamp securely.
• Connection method: Look for a detent hole or locking mechanism that matches your powerhead.
• Brand claims: “Universal” usually means “fits attachment-capable couplers,” not “fits every trimmer.”

Quick fit check (what you should see)

Use this as a fast visual guide.

What you see on the trimmer	What it usually means	TrimmerPlus attachment likely?
Fixed straight shaft with no coupler	Not attachment-capable	No
Coupler with clamp/knob between engine and shaft	Attachment-capable	Yes
Release button/pin plus clamp	Standard attachment interface	Yes
Worn, loose, or cracked coupler	Unsafe connection	Not until repaired

Why it matters

A mismatched coupler can slip, vibrate excessively, or fail to lock, which affects cutting performance and can damage the drive shaft. Verifying the coupler and shaft interface first helps you avoid returns and protects the trimmer’s drivetrain.

If the attachment will not lock in

Try these practical checks:

• Clean debris from the coupler and attachment tube.
• Inspect for a bent locking pin or damaged detent hole.
• Tighten the clamp fully and re-seat the attachment.
• Check for driveline wear (rounding of the inner shaft ends).
• If the engine runs but the attachment does not spin, inspect the lower driveline.

For the Craftsman 316711021 gas trimmer, the “best” .095 trimmer line is the one that matches your cutting style: twisted line for quieter, cleaner cutting; serrated or square line for heavy weeds; and round line for longest spool life. Confirm the maximum line diameter and head type in the 316711021 owner's manual.

What we recommend for .095 line (by use case)

• Everyday trimming and edging: round .095 line (smooth feed, long wear)
• Thick grass and moderate weeds: twisted .095 line (good balance of durability and noise)
• Heavy weeds and tough stems: square or serrated .095 line (more aggressive cut, can wear faster)
• Less vibration and noise: twisted line typically runs quieter than square
• Fewer breaks near fences and rocks: premium co-polymer lines usually resist snapping better

Quick comparison: which .095 line profile to choose

Line profile	Best for	Tradeoff
Round	General trimming	Least aggressive on heavy weeds
Twisted	Clean cut, lower noise	Can be slightly pricier
Square	Thick weeds	More noise and faster wear
Serrated	Very tough growth	Can increase drag and fuel use

Fit and performance checks for model 316711021

Use these checks before buying a large spool:

• Verify the maximum line diameter your cutting head supports in the 316711021 owner's manual
• Match the line to your cutting head style (bump-feed vs. fixed line)
• If the head jams, step down to a slightly smaller diameter or switch to round line
• Keep line length even on both sides to reduce vibration
• Store line sealed; dry line gets brittle and breaks more easily

Why it matters

Using the right .095 line helps your Craftsman trimmer cut cleaner with less bogging, reduces head jams, and can extend cutting head life by lowering vibration and heat buildup.
