2003 John Deere 9750 STS

The John Deere 9750 STS is an acre eater. On my recent ride on this impressive combine I asked the driver how he liked the combine. He said it is the best combine he had ever driven. He said the only hard part about using an STS was keeping the combine fed with grain. You can harvest match faster than on the 9610's of the past and still keep a clean sample.  It often feels like you can not get across the field fast enough to keep the grain coming in. In an average 8 hour day the driver said he was covering 110 acres of wheat with the 9750 STS. That is an impressive number.

At the heart of the 9750 STS is a rotary type threshing system. John Deere uses a longitudinal threshing and separating module. This unit is the STS on the decal "Single Tine Separation." The STS system has a Tri-Stream flow where the grain flows through the rotor at an expanding rate. The crop enters a concentric threshing cage where the STS systems pull and release force pulls the crop from the small entry end of the cage to the larger end. This action helps free trapped grain and increases savings in the bin.

The 9750 STS’s 300 bu bin is impressive. It has flared extensions around the top to hold 50 bushels of grain and a neat, wide open design. There is a window inside the cab that allows you to see the grain flowing into the big bin. The field that  I rode along in was averaging 80 bu. of wheat per acre. The 9750 STS equipped with a 30ft grain head would fill the bin in 5 to 8 minutes. The harvest ability of the 9750 STS is so big it is often necessary to harvest and unload its bin at the same time. The 20ft unloading auger allows tractors and carts to pull right up and travel along side.

The 9750 STS cab makes you wonder how farmer could harvest grain with an open station 45 over fifty years ago. During my visit to the wheat field a retired farmer stopped out to take a ride on the 9750 STS. He wanted to see this modern mega combine in action. During his childhood he remembered helping his Dad and uncle on an old Baldwin Gleaner combine. He would stand on the side of the combine and tie sacks of grain. Back then there were no semis or dump trucks to handle bulk grain so wheat was sacked right on the combine and hauled to town in a horse drawn wagon. Plus the combine was pulled by a team of mules. Flash forward the 9750 STS and its operator command center. You have an air conditioned cab with monitors telling you the average bushels per acre, grain moisture and a GPS mapping system using a satellite to record the crop conditions and yields through out the field. The wrap around glass window allows for a clear view of the crop and other combines and grain carts operating near by. The entire  28,776 lb combine is controlled by the drivers thumb. The CommandTouch control system allows the driver to adjust the header height and speed, unloading auger and field speed.

John Deere’s 9750 STS is a harvest leader with its impressive technology and capabilities. On August 17, 2003 John Deere will release a new series of combines under the 60 series banner. The 9760 STS should prove to be an even more impressive machine along with an even bigger 9860 STS. I have heard that STS sales have been so strong for Deere that they will no longer develop a conventional combine line. We shall see in August.

John Deere 9750 STS Precision II and 1/64 models

The Precision II Series of Ertl replicas was launched in September 2000 with the release the 1/32 precision detailed 9750 STS combine. Precision II models offer the highest detail features on 1/32 replica models of large modern farm equipment.

The 9750 STS precision II is a hand assembled model with over 100 pieces that replicate the real combine in very accurate detail. The replica includes a life like 25ft replica of the John Deere 925 grain head as well as an 8 row row 893 corn head with service able snouts. The heads are interchangeable and attach just like the real ones. All of the side panels on the Precision II 9750 STS lift to expose the guts of the combine. The mechanical detail underneath this replica is well done by Ertl featuring belts, pulleys and other combine parts. The engine area is easily accessible with a retractable ladder that pulls in and out. If you were 1/32 scale you could walk right into the replica cab because the door opens to show off the operator friendly cab interior. The roof of the cab has a radio antenna and the ladder swings to the front for transport. The ladder is complete with a fire extinguisher. The big grain tank is detailed just like the real 9750 STS and includes the see through window to the cab.

The 9750 STS Precision II is an impressive collectible that any John Deere or combine collector should include in their collection. 2003 is the last year Ertl will offer this replica and it will only be around while supplies last. Hopefully a Precision II 60 series model is in the works
