Description
Overview:
The Tap-N-Go Trimmer Head T35X M12 Semi Auto (with Ball Bearing) is a genuine Husqvarna cutting head for straight-shaft brushcutters and grass trimmers. It uses a hard-wearing polymer body with a reinforced internal hub and a ball bearing resting surface to resist wear under regular tapping. The semi-automatic "Tap'n Go" system feeds line when the head is lightly tapped to the ground, keeping cutting performance steady with minimal downtime. It mounts via an M12 thread and is suited to machines in the 30-42 cc range, including popular Husqvarna models such as the 535RXT and 135R. Designed for 2.4-2.7 mm nylon line, it offers reliable grass and weed trimming in domestic and professional settings while maintaining smooth, balanced running.

Typical Applications:
General grass trimming, edging, and clearing around trees, posts, fences, kerbs, borders, and garden beds. Suitable for maintaining verges, pathways, and rough grass in gardens, allotments, estates, and commercial grounds where frequent stop-start line feeding would slow work without a semi-automatic head.
