The Allied PTO winch option is back. Responding to many requests from customers to bring back the PTO-driven winch option for the new 750-850J/K dozers, Allied worked closely with John Deere engineering to provide this winch option.
The John Deere 750J/K and 850J/K dozers represented a major departure from the John Deere 750C and 850C. Until recently, the current "J" and "K" series dozers offered only the high-flow pump option for hydraulic winches while the previous "C" series dozers offered the PTO option. For a rear-mounted towing winch, this change meant moving from the PTO-driven Allied W6F winch to the Allied H6H hydraulic winch. For most North American applications, the new Allied H6H hydraulic winch has proven to be very successful and readily accepted.
While a hydraulic winch is great for smooth speed control for most oil field work, power line sagging and construction applications, its line speed is considered too slow in certain applications, particularly for production logging outside of North America.
Furthermore, a PTO winch option configured for logging is available from other competitive dozer manufacturers such as Caterpillar and Komatsu. John Deere customers who remember the strong power and fast line speed of the Allied PTO winch on 750C and 850C have been particularly eager to see the additional choice of a PTO-driven winch back on the current-generation machines.
Thanks to excellent cooperation between John Deere Engineering and Allied Systems Company, the PTO-driven W6F winch for current-generation 750 and 850 "J" and "K" series dozers is now available. The PTO delivers all the available engine horsepower to the winch for high line pull and fast line speed. This is especially welcome news for forestry customers in tropical logging, where both high line pull and fast line speed are required for productivity.
John Deere dealers now have the choice of Allied H6H hydraulic winches for general applications where smooth line speed control is important, and the PTO-driven W6F winch for fast line speed, especially for high-volume logging.
To get your new 750-850J/K with PTO option, just specify JD option code 7975. The dozer will arrive with the PTO installed, ready to accept the W6F winch.
Following initial winch testing at Deere Engineering in Iowa, USA, the first customer unit with PTO-driven winch went into service in New Zealand in April 2012. John Deere dealer Cableprice Equipment in Rotorua, New Zealand installed an Allied W6F winch equipped with logging arch on an 850J. Dealer sales representative Paul Roche said the winch delivered everything their customer had hoped for.
A fleet of W6F winches is on its way to John Deere dealer P.T. Hexindo in Indonesia to fit on 750-850J dozers destined for the tropical forests.
Production logging depends on speed, and the W6F winch delivers both high line pull and fast line speed. This combination keeps the John Deere 750J/K and 850J/K more competitive in tropical forestry markets.

The W6F winch on a John Deere 850J is ready to go to work in a New Zealand forest. The PTO winch is configured for fast line speed and high line pull for logging. The optional arch shown enhances productivity by lifting the butt ends of the logs to permit larger loads and faster travel speed to the landing.
The H4A features Self-Contained Hydraulics (SCH) design. The hydraulic pump and motor are contained inside the winch frame for protection and integrity, and are isolated from the dozer hydraulic system. Winch power comes from the John Deere PTO output.
