N277078 Cotton Picker Spindle - Right Hand Pro12 Spindle for John Deere Cotton Picker

N277078 Cotton Picker Spindle is a heavy-duty right-hand spindle designed for John Deere Pro12 and Pro16 spindle-type cotton picker row units.

**Material features**: The spindle substrate adopts 20CrMnTi alloy steel with carburizing heat treatment. It features double chrome plating with 90-micron chrome layer; surface hardness reaches 62HRC while the core maintains good toughness. This material combination provides outstanding wear resistance, anti-corrosion performance and impact resistance, resisting abrasion from cotton fiber, dust and field debris during long harvest seasons.

**Product characteristics**: Precision-machined spiral grooved teeth on spindle tip deliver stable fiber-grabbing performance. The optimized tooth profile picks cotton cleanly and enables smooth doffing by the doffer, minimizing leftover lint on spindle and reducing cotton waste. The gear end is precisely machined to perfectly mesh with spindle drive gears, ensuring stable rotation and lower operating temperature during continuous high-speed picking. Worn, dull or chipped spindles will cause poor fiber capture, high cotton drop loss and reduce overall harvesting capacity.

**Compatibility**: Direct aftermarket replacement for OEM N277078, fully compatible with John Deere cotton picker models including 7660,7760,9900,9910,9920,9930,9935,9940,9950,9960,9965,9970,9976,9986,9996 and CP690. Inspect spindle sleeve, bushing and driving gear, and remove accumulated cotton lint before installation. Install N277078 spindle to restore picking performance, cut field cotton loss and maximize cotton yield during harvesting season.
