Description
Overview:
This Retarder Assembly is a genuine Husqvarna part designed for the company's petrol power cutters. Built for dependable control of rotational overrun, it helps slow the drive system and cutting wheel when the throttle is released, improving safety and handling. The assembly is engineered for a precise fit on Husqvarna K760 and K750 machines and selected later models, maintaining correct function of the saw's drive and braking interaction. Manufactured to OEM standards with robust materials, it withstands the heat, vibration, and dust typical of concrete and masonry cutting. Using the genuine assembly helps restore smooth deceleration, reduces wear on related components, and keeps the machine working as intended in demanding site conditions.
Key Features:
- Genuine Husqvarna OEM part for reliable fit and function
- Designed to decelerate the drive system and reduce wheel overrun
- Durable construction to handle abrasive cutting environments
- Consistent performance under heat, dust, and vibration
- Supports safer operation by aiding controlled run-down of the wheel
- Helps reduce premature wear on linked drive components
- Direct replacement for the original unit on listed models
- Suitable for routine maintenance or restoring performance after wear
Typical Applications:
Used on Husqvarna power cutters in construction, utilities, landscaping, and emergency work to control run-down after cuts in concrete, asphalt, stone, and metal. Ideal when a saw begins to overrun on stop, or when deceleration becomes uneven, indicating wear in the retarder system. Helps maintain predictable tool behaviour during frequent start/stop tasks on busy sites.
Also known as:
Brake unit, wheel retarder, decelerator assembly, drive retarder, speed control assembly. Sometimes referred to as an overrun control or slowdown unit within the belt and clutch system of a power cutter.
