Title:
BOLT (JD-HXE29393)
Description:
John Deere HXE29393 Cutterhead Knife Bolt is a genuine Original John Deere fastening component engineered to securely retain the knives within the cutterhead assembly of compatible 8000 Series self-propelled forage harvesters. As a critical part of the knife mounting system, the bolt helps maintain secure knife positioning during high-speed cutterhead operation.
The HXE29393 is designed specifically for the cutterhead mounting arrangement used on the 8000 Series forage harvesters. Its robust fastening construction is suited to the substantial vibration, impact and rotational forces generated during intensive crop processing, helping maintain the integrity of the knife assembly during operation.
John Deere’s forage-harvester parts documentation identifies HXE29393 as the cutterhead knife bolt and shows it used with the 8000 Series cutterhead system. Parts documentation also lists the bolt in the knife mounting assembly alongside the knife brackets, threaded bars and cover plates.
Using the correct Original John Deere knife bolt helps maintain the intended clamping arrangement and secure attachment of the cutterhead knives. Proper installation is particularly important because the cutterhead operates at high rotational speed and is subjected to demanding harvesting loads.
