China CSS Hydraulics Harvester


Eaton components are selected by China’s largest cotton harvesting equipment producer

Eaton® transmissions, pumps, motors, manifolds and steering products are standard equipment on GAIG’s large, self-propelled 4MZ-5 cotton harvesters.


Eaton has won business on cotton harvesters made by Guizhou Aviation Industry Group (GAIG) Agriculture Equipment Company, Ltd. of Shihezi, Xinjiang, China, the country’s largest producer of cotton harvesting equipment.

Eaton Hydraulics Greater China, based in Shanghai, is supplying a packaged hydraulic solution containing an Eaton Series 1 heavy-duty hydrostatic transmission, 420 Series open-circuit piston pump, valve manifolds, XCEL 45 steering unit, and Char- Lynn® LSHT motor for GAIG’s large, self-propelled 4MZ-5 cotton harvesters.


The Eaton sales team began calling on the customer (formerly known as Ping Shui) several years ago to introduce Eaton products and how an Eaton packaged solution would provide complete hydraulic system functionality on the cotton harvesters, as well as improve drivability and productivity.

They explained how Eaton’s Application & Commercial Engineering (ACE) team would design the prototype’s hydraulics circuitry around GAIG’s technology, with a close eye on keeping the package within a compact envelope and sizing components for maximum performance. They emphasized that Eaton’s total system supply included onsite service and technical support that would last for the lifetime of the products.

GAIG decided to give Eaton an opportunity to prove its claims by commissioning Eaton to provide prototypes in a short time frame.

However, there was a big hurdle to overcome— GAIG gave a competitive hydraulics provider the same go-ahead to begin prototype development of a packaged solution.


Eaton filled the order within the delivery time frame and worked alongside the customer—as did the competitive hydraulics provider— to improve overall system performance as lengthy infield trials took place. During this time, GAIG leaned more and more on Eaton’s application expertise and field technical support that surpassed its expectations.


Eaton’s total package design and superior responsiveness resulted in ongoing batch supply orders that began in January 2011.

“Our new business with GAIG illustrates Eaton’s expertise in diverse, heavyduty hydraulics applications in the agriculture machinery market in China,” said Wayne Wang, global product manager—heavy-duty piston products. “It will strengthen our position as a major provider of hydrostatic transmission solutions among agriculture OEMs.”
