Husqvarna 966674401 T25 Universal Trimmer Head

Product Description

The HUSQVARNA 966674401 is the T25 Universal Trimmer Head, a bump-feed cutting head designed for use with Husqvarna string trimmers and compatible universal-fit trimmer shafts. This head uses a tap-to-advance line feed mechanism, allowing the operator to bump the head against the ground during operation to extend fresh cutting line without stopping the machine. It is a common replacement part installed by landscape maintenance professionals and equipment technicians servicing walk-behind string trimmers in residential and light commercial applications.

The T25 Universal Trimmer Head is suited for straight-shaft and curved-shaft string trimmers where a universal-fit bump-feed head is required. It is a direct replacement for worn or damaged trimmer heads on compatible Husqvarna trimmer models and other brands accepting universal trimmer head attachments. Typical installation scenarios include routine maintenance head replacement after line spool wear or housing damage during field operation.

Key Features

• Bump-feed line advance mechanism for uninterrupted cutting operation
• Universal fit design compatible with a range of trimmer shaft configurations
• T25 head series designed for reliable line retention and consistent feed
• Durable housing construction suited for repeated ground contact during bump-feed operation

Compatibility

Designed as a universal-fit replacement trimmer head for compatible string trimmers accepting T25-series bump-feed heads. Verify thread pitch and adapter fitment before installation.

Installation Notes

Installation should be performed by a qualified technician or experienced operator familiar with small engine outdoor power equipment. Disconnect the spark plug wire before removing or installing any cutting attachments. Thread direction on trimmer head fasteners is often reverse-threaded to prevent loosening during operation — consult the trimmer operator manual to confirm before applying force. Wear cut-resistant gloves when handling cutting line and trimmer head components.
