Spring tines are the working element of seedbed cultivators and weeders. They vibrate to shatter soil and shake off residue, then release stones without breaking. Get the steel, heat-treatment or shovel tip wrong and you either lose tines to breakage or skip weeds. Here is the buying guide.
Standard cross-sections: 32x10 mm (light tines for weeding), 45x12 mm (medium for seedbed preparation), 55x13 mm (heavy for stony ground and primary cultivation). Length typically 400-700 mm. Longer tines vibrate more, work deeper.
Spring steel 51CrV4 or 55Si7, hardened and tempered to 40-48 HRC. This gives the spring-back property without snapping. Boron steel 30MnB5 available for heavier-duty / stony conditions.
Duck-foot (sweep) has the widest cut (100-200 mm), used for full-surface weed cutting in seedbeds.
Point (chisel tip) is narrow, deep penetration, used for loosening between rows.
Sweep share (goose-foot) is intermediate, common on row-crop cultivators.
Replaceable tips save the tine body when only the tip wears out. This is the standard for commercial farming. Fixed tips are cheaper but require full tine replacement.
Most cultivators use a clamp-style mount on a square or flat bar. Confirm the bar size and clamp design before bulk order.
Bottom line: Match section + length + steel + heat-treatment + shovel tip + mount. Send OEM code or a sketch, we confirm within 24 hours.
