Brush Cutter Steel Starter Parts – Essential Components for Your Recoil Starter System
High-Durability Replacement Parts for 2-Stroke Brushcutters
Steel starter parts are essential components in the recoil starting mechanism of 2-stroke brushcutters and trimmers. These parts are subject to high stress and wear, making them common replacement items for maintaining reliable engine starting. This guide covers the key steel starter components available for brushcutters, including starter springs, pawls, and recoil assemblies.
Technical Profiles & Materials
Steel Recoil Starter Springs – The recoil spring provides the tension and recoil action that retracts the starter rope after each pull. It is attached on the starter pawl bridge and fastened by a starter pawl, enabling the starter pawl to engage and disengage effectively during engine startup . If the spring shows signs of breaks, stretching, or distortion, it needs to be replaced. Failing to replace a broken spring can render your machine unusable .
Available OEM part numbers include:
Husqvarna 503873601 (fits 326RJX, 135R, 223R, 241R, 322R, 323R, and many other Husqvarna brushcutters)
Husqvarna 501763101 (fits Husqvarna 240, Jonsered 2036, McCulloch Mac 20, and various 36-55cc models)
Echo/Shindaiwa 17723412220 (return spring for Echo and Shindaiwa trimmers)
Starter Pulley Claws / Cups – The starter pulley claw (also called a pawl or cup) engages with the starter mechanism to crank the engine. Steel construction provides superior durability compared to plastic alternatives, resisting wear and deformation during repeated starting cycles.
Available OEM part numbers include:
Mitsubishi KS30047AA (fits TL33, TL43, TL50, TL52)
Shindaiwa A052000350 (starter pulley assembly for C-250, C-260, C-270, T-250, T-260, T-270 series)
Complete Recoil Starter Assemblies – Full recoil starter units are available for direct replacement when multiple components have failed. These assemblies are made from steel wire and are compatible with 2-stroke brushcutters, hedgerow machines, lawnmowers, and ground drills .
