A pull cord replacement takes 15 to 30 minutes and costs $10 to $25
The pull cord on a lawn mower wears out from repeated yanking, fraying, or snapping inside the housing. You can replace it yourself without special tools — you need only a screwdriver, scissors, and a new cord (usually sold as a kit with the handle already attached). The job involves removing the recoil housing, unwinding the old cord, winding the new one around the pulley in the same direction, and reassembling. Most mowers use the same basic design, though the housing location and fastener count vary by brand.
Doing this yourself saves the $60 to $150 a repair shop would charge for labour. The cord itself is inexpensive; the time cost is what makes the shop visit expensive. If you are comfortable with a screwdriver and can follow the order of steps, this is a straightforward repair.
Key Takeaways
- The recoil housing sits on top of the engine and is held by two to four screws that you remove first.
- The old cord unwinds from a pulley inside the housing; note which direction it wraps before you remove it.
- New pull cord kits come with the handle and cord pre-assembled, so you only need to wind the cord around the pulley and reassemble.
- The spring inside the housing is under tension; keep your fingers clear of the pulley when you open the housing.
- Winding the cord in the wrong direction will cause the handle to stick or the cord to jam on the next pull.
What you need before you start
Gather a screwdriver (usually Phillips head, though some mowers use slotted or square-drive), scissors or a utility knife, and a replacement pull cord kit. The kit should match your mower's brand and engine size; check the engine model number on the side of the mower deck or in your owner's manual. Kits are sold at hardware stores, online retailers, and lawn mower dealers for $10 to $25.
You do not need a new spring, handle, or pulley unless yours is visibly cracked or bent. Most kits include only the cord and handle, which is all that wears out. If the handle is broken but the cord is fine, you can buy a handle separately for $5 to $8.
Work on a flat surface with the mower on its side or upright, depending on the housing location. If you tip the mower on its side, tip it so the carburetor side faces up — this prevents oil from leaking into the air filter. Disconnect the spark plug wire before you begin, even though you will not be starting the engine; this is a safety habit that prevents accidental starts.
How to remove the recoil housing
Locate the recoil housing on top of the engine. It is a plastic or metal box with a handle sticking out of it. Remove the two to four screws holding it to the engine block using your screwdriver. Keep the screws in a small container so you do not lose them. Lift the housing straight up and set it on a clean surface.
Inside, you will see a pulley (a wheel with a groove around it) and a spring coiled around the housing wall. The spring is under tension and will try to unwind when the housing is open. Do not poke at it or try to adjust it. Your job is only to remove the old cord and install the new one.
Look at how the old cord is wound around the pulley. It will wrap either clockwise or counterclockwise — note this direction because the new cord must wrap the same way. If the old cord is broken or frayed, you may need to pull the knot out of the pulley hole with pliers or a small hook. Once the cord is free, discard it.
Installing the new cord
Thread the new cord through the hole in the pulley, the same direction the old cord went. Pull the cord through until the knot at the end catches in the pulley hole. The knot should sit snug in the hole and not slip through. If your kit's knot is too small, tie a larger knot or wrap the existing knot with thread to thicken it.
Now wind the cord around the pulley in the direction you noted earlier. Wind it tightly and evenly, keeping the loops parallel to each other. Most pulleys hold three to five wraps of cord. Wind until the pulley is nearly full, leaving just enough room for the cord to turn freely without rubbing the housing wall.
Once the pulley is wound, pull the free end of the cord up through the handle hole in the housing. The handle should sit flush against the top of the housing when you pull the cord taut. If the handle sits too low or too high, you may have wound the cord the wrong number of times or in the wrong direction — unwind and try again.
Reassembling the housing and testing
Lower the housing back onto the engine block, aligning the screw holes. Insert and tighten the screws in a crisscross pattern (top-left, bottom-right, top-right, bottom-left) so the housing seats evenly. Do not overtighten; snug is enough. Reconnect the spark plug wire.
Pull the cord slowly a few times to make sure it moves freely and returns smoothly. The cord should not stick, jam, or feel rough. If it does, the cord may be wound too tightly, wound in the wrong direction, or pinched between the housing and pulley. Open the housing again and check the winding direction and tension.
Once the cord pulls smoothly, start the mower and let it run for a minute. The pull cord should work normally during operation. If the handle sticks or the cord does not retract fully, stop the mower, disconnect the spark plug, and open the housing to inspect the winding again.
Common mistakes and how to avoid them
The most common error is winding the cord in the opposite direction from the original. This causes the handle to stick partway out or the cord to jam. Before you wind, take a photo of the old cord's direction or mark the pulley with a pen so you remember which way to go.
Another mistake is winding the cord too loosely. Loose wraps will slip on the pulley and cause the handle to stick or the cord to retract unevenly. Wind firmly and keep the loops parallel. If the cord is too tight, the pulley will be hard to turn and the handle will be stiff to pull.
A third error is tying the knot wrong or making it too small. The knot must catch securely in the pulley hole and not slip through. If you are unsure, tie the knot, test it by pulling hard on the cord, and retie if it slips.
Finally, do not force the housing back on if it does not sit flush. If the housing rocks or gaps appear, the cord may be pinched or the pulley may be misaligned. Open it again and check that the cord is wound neatly and the pulley spins freely.
When to buy a new mower instead of replacing the cord
If the recoil housing itself is cracked, the spring is broken, or the pulley is stripped or bent, a replacement cord will not fix the problem. A new housing assembly costs $40 to $80 and requires the same removal steps, but you are replacing the whole unit instead of just the cord. If your mower is more than 10 years old and the housing is damaged, compare the cost of a new housing to the cost of a used or refurbished mower in your area.
If the cord breaks repeatedly within a few months of replacement, the problem may be a bent pulley, a misaligned housing, or a spring that is too tight. These issues require a professional inspection. A repair shop can diagnose the cause and tell you whether a new housing or a full mower replacement makes sense for your situation.
Frequently Asked Questions
Can I use any pull cord, or does it have to match my mower brand?
The cord itself is standard — most mowers use the same diameter and material. What matters is the handle and knot assembly. Buy a kit that lists your mower's brand and engine model to may support the handle fits your housing and the knot size matches your pulley hole. A generic cord without the right handle will not work.
What if I wind the cord the wrong direction?
The handle will stick or the cord will jam on the next pull. Open the housing, unwind the cord, and wind it the opposite direction. It takes only a few minutes to correct. If you are unsure which direction is correct, look at the pulley's groove — the cord should follow the groove naturally when wound in the right direction.
How tight should the cord be wound?
Wind it firmly so the loops do not slip, but not so tight that the pulley is hard to turn by hand. You should be able to rotate the pulley with light finger pressure. If the handle is stiff to pull or hard to retract, the cord is too tight and you should unwind and rewrap it more loosely.
Do I need to drain the fuel before I start?
No, but you must disconnect the spark plug wire to prevent accidental starts. If you tip the mower on its side, tip it so the carburetor faces up to avoid oil leaking into the air filter. The fuel can stay in the tank.
How long does a new pull cord last?
A properly installed cord usually lasts three to five years of regular use. Cords wear out from sun exposure, repeated friction, and the stress of pulling. If you store your mower indoors and use it seasonally, the cord may last longer. If you use the mower daily or leave it outside, it may wear out sooner.
