|Plowing depth||305 mm / 12 in. / 356 mm / 14 in.|
Excellent fore-aft and vertical clearance between standards (arrows above) allows the soil and residue to freely flow through the plow:
Fore and aft
864 mm (34 in.)
851 mm (33.5 in.)
The operator can change the plow's width of cut to match the tractor horsepower and soil conditions.
The rigid plow has a width-of-cut range of 356 mm to 559 mm (14 in. to 22 in.) on land and 508 mm to 559 mm (20 in. to 22 in.) in furrow.
The flex plow has 356 mm to 559 mm (14 in. to 22 in.) of cut.
Adjustments are made by adjusting two turnbuckles (arrows) to a predetermined length specified in the operator's manual.
The rigid model uses a scissor-type landing adjustment to set the first bottom in relationship to the rear tractor tire for the different widths of cut:
Land wheels help to stabilize the plow in both the working and transport positions. They also control the depth of plowing and work in conjunction with raising and lowering the plow.
Land wheels on rigid plows are tied to the Adjust-O-Cut bar for automatic setting for each width of cut.
A single wheel is standard on the six-bottom model; dual wheels are standard on the seven- and eight-bottom models and optional on the six-bottom model (recommended in softer soils).
Land wheels on flex plows have four adjustment positions (arrow) to allow setting the assembly for 406-mm, 457-mm, or 508-mm (16-in., 18-in., or 20-in.) widths of cut or transport:
Dual, staggered Walk-Over wheels are standard on flex plows:
The double-pivot design of the spring-reset standard uses tension spring force to return the standard to the working position.
Safety-trip standards provide an economical means for protection—suited for areas without rocks:
The NU bottoms are set behind the mainframe to prevent the mainframe from becoming a pinch-point for residue. They are designed for light draft and high-speed plowing.
Available in 400-mm (16-in.) and 450-mm (18-in.) sizes with an unpolished finish.
The maximum plowing depth are as follows:
400 mm (16 in.)
305 mm (12 in.)
450 mm (18 in.)
356 mm (14 in.)
* In some soil conditions at plowing depths in the 254-mm to 356-mm (10-in. to 14-in.) range, soil may boil over the moldboard, resulting in poorly defined furrows.
Both the NU 400 and the NU 450 come standard with heavy-duty, full-cut shares.
A variety of shares are available through Parts to match the plowing conditions:
|NU400||Regular, narrow cut|
|NU400||Heavy duty, narrow cut|
|NU400||Heavy duty, full cut|
|NU450||Heavy duty, narrow cut|
|NU450||Heavy duty, full cut (standard equipment)|
|NU450||500-mm over-cut (for use when wide widths of cut or complete slicing is required)|
|NU450||Hard-faced gumbo (for heavy soil conditions when penetration is a problem|
|NU400||Hard-faced (for areas where abrasive soil causes rapid wear of heavy-duty shares—not for use in rocks)|
|NU450||Hard-faced (for areas where abrasive soil causes rapid wear of heavy-duty shares—not for use in rocksfor)|
The gumbo moldboard (A32211) is available for NU 400 bottom and is recommended for use in heavy soil (gumbo) conditions. It is similar to the NU 400 bottom except that it has less area at the wing tip.
John Deere furnishes a replacement share for any John Deere plow share that breaks before the share reaches the following wear limits (labor not included; wear to be measured perpendicularly across the middle of the front bolt hole):
Plastic or steel trashboards can be added to NU bottoms to improve coverage in tall, heavy residue. Plastic trashboards are only recommended for non-abrasive soils where scouring is a problem with steel trashboards.
Economical design of the shear-bolt coulters is suited for areas without rocks:
Adjustable-force cushion coulters are suited for rocky or normal field conditions:
|Plowing depth||305 mm
|Option 2||Reversible bottom - steel: 450 mm
|Option 1||203x203 mm
