Product Description
Mitchell 82037 Drag Knob – Genuine Replacement for 750 Fly Series
The Mitchell 82037 Drag Knob is a specialized external component designed for the Mitchell 754 and 758 fly reels. Unlike spinning reel drag knobs, this part is engineered to control the tension on a center-pin fly reel spool, providing the delicate pressure needed for protecting light tippets while offering enough resistance to tire out a fighting fish.
Constructed from a durable, UV-resistant composite with a precision-threaded core, the 82037 features an ergonomic rim for easy adjustment, even with wet or gloved hands. Replacing a worn or stripped drag knob is essential for maintaining the smooth, non-stuttering line release required for high-level fly angling.

Compatible Models
The 82037 drag knob is the standard for Mitchell's mid-to-large capacity fly reel series:

Mitchell 754 (Standard click-and-pawl/disc drag fly reel)
-
Mitchell 758 (Large arbor / higher capacity variant)
-
Mitchell 750 Series (Select variants utilizing the same threaded spindle)
Technical Insight: The 754 and 758 series reels use a relatively simple but effective drag stack. If the drag feels "jerky" after installing a new knob, the issue likely lies in the 82038 Drag Spring or the 82039 Friction Washers located behind the knob. Ensure the internal spring hasn't lost its tension or become flattened over time. You can verify the part sequence by downloading the official PDF diagrams at www.reelschematic.com.
Professional Maintenance & Lubrication
Fly reel drag systems are often exposed to water and grit. Proper lubrication ensures the knob doesn't seize and the drag remains consistent.
-
Threaded Interface: Apply a light coat of Deuthlon Reel Grease to the threads of the knob and the spindle. Its "Dust-Shield" properties prevent moisture from entering the threads, which is a common cause of "frozen" drag knobs in fly fishing.
-
Friction Surface: For the disc drag components inside the reel, use a microscopic amount of Deuthlon Drag Grease. This specialized lubricant eliminates "stiction" (the tendency of the drag to stick before it starts sliding), ensuring a perfectly smooth line release from the very first pull.
Why Choose Genuine Mitchell 82037?
The Mitchell 82037 is designed with the exact thread pitch required to match the Mitchell fly reel spindle. Aftermarket knobs often use generic threading that can strip the softer aluminum or brass of the main shaft. Using a genuine factory replacement ensures that the "click-stops" on the drag settings remain crisp and that the knob stays secure even during the high-frequency vibrations of a running fish.
