3.75” Speed-Feed Trimmer Head – High Performance & Rapid Load

Stop fumbling with line. Start cutting.

The Speed-Feed trimmer head is the gold standard for professionals and homeowners who can’t afford to waste time. Reload your trimmer line in under 30 seconds without taking the head apart. No loose springs, no complicated disassembly — simply feed the line through, twist the knob, and get back to work.

Which Speed-Feed Head Do I Need?

Choosing the correct head size is important for performance and compatibility.

Choose the 3.75” head (this listing) if:

You use a cordless / battery trimmer
Your tool has an electronic brake
You use a petrol trimmer under ~30cc
You want faster spin-up and smoother stopping behaviour

Choose the 4.5” Heavy Duty head instead if:

You use a petrol trimmer ~30cc and above
You want maximum durability and longer run time between reloads
You do heavy commercial work

⚠️ Important Compatibility & Fitment Notes

Ideal for Cordless Users
This 3.75" head is a lower-mass unit specifically recommended for high-torque cordless trimmers with automatic electronic braking (such as Makita DUX-series / DUR-series or Milwaukee FUEL tools).
Unlike larger heads, this model stops more cleanly with the motor, reducing the chance of line retracting during spin-down.

M12 Bolt Warning
This kit will not fit large-frame professional trimmers that require an M12 bolt, including (but not limited to):
Stihl FS131, FS240, FS311
Husqvarna 545RXT

Straight Shaft Only
Designed for straight-shaft trimmers only.
Will not fit curved/bent-shaft models or machines with fixed or non-removable factory heads.

WARRANTY OVERVIEW

Jono & Johno offers a 12-month warranty on most products.

We pride ourselves on selling good quality gear and will be fair and prompt in honouring our warranties. If you’re in trouble, we’ll help you out.

WHAT IS COVERED?

The exact warranty coverage depends on two factors:

Whether the fault is due to user error or a manufacturer defect
Whether the fault is minor or major

Minor faults caused by the user

Parts will be supplied for repair at the user's expense.

Minor faults caused by the manufacturer

Customers are expected to perform basic repairs as part of our warranty process.
Jono & Johno will provide replacement parts and instructions for simple repairs, such as installing a recoil starter.
Jono & Johno will determine whether a fault is classified as minor.
If unsure about a repair, contact us, and we’ll assist you.

Major faults caused by the manufacturer

Jono & Johno will arrange a return, refund, or replacement at our expense.
If preferred (and at our discretion), we may provide replacement parts and contribute to labour costs if you can perform the repair.

Major faults caused by the user

Where possible, parts will be supplied at the user's expense.
If the item cannot be repaired by the user, we offer repairs at our workshop at $80 AUD per hour.
The customer will need to cover return shipping costs for user-related faults.

RETURN PROCESS & SHIPPING COSTS

If you need to return your product:

In-store return: If you're near a Jono & Johno outlet, you can return the product in person. Contact us first to arrange a return authority.
Shipping return: If you are not within driving distance, we will provide a return address.
- If the fault is due to a manufacturer defect, we’ll cover return costs.
- If the fault is user-related, the customer is responsible for return shipping.

EXCEPTIONS TO THE RULE

Some products are not covered by warranty, including:

Engines used in go-karts and stump grinders

OUT-OF-WARRANTY PRODUCTS

If your product is out of warranty and has failed despite minimal use, contact us. We may assess it on a case-by-case basis. If a manufacturer defect is identified, we aim to be fair in resolving the issue—but this is at our discretion.
