JOHN DEERE - R990R Back
JOHN DEERE REAR MOUNT MOWER-CONDITIONER R990R
TURN 10-HOUR DAYS INTO 460-ACRE DAYS
The new John Deere Front and Rear Mower-Conditioner can cut up to 32.5 feet (9.9-m) in one pass. Thats up to 46 acres an hour. And with two new models for the Front-Mounted MoCo, the F310R and F350R, and three new Twin Rear-Mounted MoCos, the R870R, R950R and R990R, cutting is faster and better than ever.
Paired with a tractor with a minimum of 210 horsepower, a front hitch and PTO, you can enjoy a comfortable cab environment while being able to change cutterbar angle without leaving the tractor seat. The convenience of quick change knives allows you to change a knife in less than 15 seconds.
Not only can you cut wide, with up to a 32.5-foot (9.9m) cutting width, but you can transport narrow at just over 11 feet. The rear-mount mower-conditioners fold up without leaving the cab, making transport fast and easy.
Plus, if your tractor has AutoTrac, you can add the benefts of John Deere guidance, reducing operator fatigue and ensuring your cutterbar is cutting a full width in every pass.
USE FRONT HITCH FOR MAXIMUM PRODUCTIVITY
The F310R and F350R Front-Mounted Mower-Conditioners are used to maximize the potential of the 7R or 8R Tractor equipped with a front power take-off (PTO) and front hitch. This 1000-rpm mower-conditioner can be combined with the following 1000 rpm mower-conditioners to increase productivity:

HIGH-SPEED ROTARY DISC CUTTERBAR FOR CUTTING IN TOUGH CONDITIONS
Large farms, machinery rings and contractors need high quality output, and ease of serviceability.
The cutterbars are fast mowing, with high quality work and reliable set-up.
Each disc is protected against heavy shocks with a shear point located on the disc drive.
All modules and intermediate gears are quickly and easily interchangeable.
To meet high quality output, the cutterbar is an oil-immersed, gear-driven cutting bed.
All discs are offering an orbital cutting diameter of 440 mm (17.3 in.).
With seven discs, the cutting width will be 3.1 m (10.2 ft). With eight discs, the cutting width will be 3.5 m (11.5 ft).
Disc speeds are 2986 rpm.
To meet serviceability, the cutting bed is lubricated for life:
No oil changes necessary.
Discs are fitted with quick change knives technology.
Cutting height is from 35 to 85 mm (1.4 to 3.3 in.).
Time needed to change a knife is below 15 seconds. It is an efficient way to gain up to 30 minutes of maintenance time on the mower conditioners.
CONDITIONING AND SWATH DELIVERY
Producers need to be reactive to weather conditions when harvest is ready. They must cut faster, with efficient conditioning using swathing or wide spread.
The steel fingers provide the right impact on the plant to remove the waxy coat.
The R870R is equipped with four V-shaped tines in on both sides of the conditioner and 76 straights.
The R950R and R990R are equipped with four V-shaped tines in on both sides of the conditioner and 100 straights.
This accelerates the drying process while requiring little maintenance.
To improve productivity:
Two conditioning positions are available at 755 or 1000 rpm.
Speed change is done by a simple selector on the gear box.
The desired swath size can easily be obtained with adjustable swath deflectors:
From 1.2 to 2.0 m (3.9 ft-6.6 ft) on the F310R and F350R
From 1.45 to 2.40 m (4.7 to 7.9 ft) on the R870R
From 1.85 to 2.40 m (6.1 to 7.9 ft) on the R950R and R990R
Wide spread is available on all machines when very fast drying is required
Proper conditioning in a wide range of crops can be achieved when the conditioner is properly adjusted.
The impeller conditioner works well in legumes, especially alfalfa and most all-grass crops. Impeller conditioners are not recommended for thick-stemmed or cane-type crops, such as sudan or sudex, or crops more than 1.5-m (5-ft) tall.
WINDROWING SOLUTIONS TO MATCH ANY NEEDS
The available room for a windrow is a function of wheel spacing and tire width. The windrow width of the F310R and F350R Front-Mounted Mower-Conditioners may be narrower than the windrows from a twin rear-mounted mower-conditioner if the forming shields are adjusted so the tractor does not drive on the windrow that is produced.
The desired swath width can easily be obtained by loosening the handle on each side and moving the adjustable swath deflectors to the desired position. Swath width is adjustable from 1.2 to 2.4 m (3.9 to 7.9 ft) on the F310R and F350R Front-Mounted Mower-Conditioners.
The forming shields are easily adjusted to match harvest requirements. No tools are required to adjust the forming shields. Windrow width for the R870R, R950R, and R990R on each unit can be adjusted from 1.3 to 3.2 m (4.3 ft. to 10.5 ft).
