DemJamr Trimmer Head Spring

These springs are specifically engineered for T25, T25B, T25BB, and P25 trimmer heads. They are designed to fit Husqvarna, McCulloch, and Partner models that utilize these specific head types.

You likely need a replacement if your bump-feed mechanism has stopped working or feels sluggish. If the trimmer line fails to advance when you tap the head on the ground, or if the head feels loose and lacks tension, the spring has likely lost its elasticity or broken.

Replacing the spring is a straightforward maintenance task. You typically just need to unscrew the trimmer head cap, remove the old, worn-out spring, and seat the new one in the center before reassembling the head.

Trimmer springs are small, easily lost during disassembly, and subject to significant wear over time. Providing a pack of eight ensures you have plenty of spares on hand for routine maintenance or accidental loss without needing to reorder frequently.

Compatibility is determined by the trimmer head model rather than the shaft type. As long as your trimmer is equipped with a compatible T25, T25B, T25BB, or P25 head, these springs will function correctly regardless of whether your trimmer has a straight or curved shaft.
