Just before press time, Deere unveiled its new combines, tractors and implements at its annual dealer meeting. Here is a photo preview of what you'll see on dealer lots this fall.

50 series

Rumors were right. Deere is coming out with a rotary combine, called the STS (Single Tine Separation), to provide optimum grain quality and higher capacities than were possible with its cylinder/concave designs. Two STS models will be available for year 2000: the 9650 STS and the 9750 STS. Both use a feed accelerator for higher-capacity feeding and a single tine-separator system for threshing and separating.

This design is based on Deere's CTS (Cylinder Tine Separation) combine, which the company first released in 1991 to meet the challenges of rice harvesting and, later, other tough-to-separate crops such as high-yielding barley.

The STS models are only part of Deere's new 50 series, which also includes four new cylinder/walker combines (9450, 9550, Sidehill 9550 and 9650) and a new 9650 CTS combine. They replace the current 10 series combines.

4990 windrower

Deere's first rotary windrower cuts as low as almost _1/2 in. with a new low-profile cutterbar. The 4990 features the industry's highest power rating of 172 hp, a cutting width of 14_1/2 ft. and three conditioning options: impeller conditioning, urethane rolls or new fluted steel rolls.

7000 TEN series

The John Deere 7510 is the latest addition to Deere's 7000 TEN series tractors ranging from 95 to 150 hp. The new model, rated at 115 hp, adds maneuverability and power to this horsepower class. Use it with hay and forage equipment or for loader work with its short turning radius and 26-gpm hydraulic pump. The other five models in the series will have new features. Coming for mid-year 2000 is the first automatic transmission for tractors, called AutoQuad II, available on models 7710 and 7810.

5105 and 5205 Advantage series

Think back to October 1997 when Deere came out with the Advantage series, a lower-priced entry in the 85- to 105-hp category, to court price-driven buyers. Now two smaller models have been added to the series: the 40-hp 5105 and 48-hp 5205. Both feature 17.4 gpm of hydraulic flow and 2,750 psi of pressure for fast lifting with the optional 521 Loader; Cat. I 3-pt. hitch with a lift capacity of nearly 3,000 lbs. to handle implements; new SyncReverser transmission with eight forward and four reverse speeds; and an open, uncluttered operator station. Shipments will begin in late fall.

9000T series

Need a tractor that offers more power to the ground, hill-hugging stability and better traction than wheeled tractors? Check out John Deere's 360-hp 9300T and the 425-hp 9400T. These large, tracked tractors work light in the spring, heavy in the fall. They were on display at farm shows last year, but are now ready to hit the fields.

8000/8000T TEN series

Control up to 12 tractor functions at once with the push of a button with a new Implement Management System, now part of Deere's new 165- to 235-hp 8000/8000T TEN series. Other new features designed to boost productivity include automatic power shift, which works in both working and transport speeds to maintain the most productive gear based on engine load, throttle setting and gear selection; and hitch slip command, which lets you set the hitch response to achieve a desired track or wheel slip rating.

Rotary cutters

Use this new heavy-duty, 10-ft. HX10 rotary cutter in fields with rocks or stumps, in high-residue crops and for contract mowing jobs. It is one of seven new John Deere models, which feature cutting widths from 5 to 14 ft. and cutting heights from 1 to 12 in. All feature an industry-exclusive double-deck design for added strength. The top deck is domed-shaped so water, grass and crop debris roll off, reducing water buildup and deck rust. The bottom deck stands up to rocks and field debris.

512 disk ripper

Tackle one-pass primary tillage in less time with the new John Deere 512 disk ripper, which features a working width of 22_1/2 ft. It folds to 18 ft. for ease of transport.
