Spring-reset standards available to work non-stop in rocks
    Spring-reset rock standardSpring-reset rock standard

    The double-pivot design of the spring-reset standard uses tension spring force to return the standard to the working position.

    • For heavier-duty applications
    • Positive reset
    • Non-adjustable trip force; factory set at 2727-kg (6000-lb) nominal
    • Floats over buried rock
    • Unhooks from ledge rock
Land wheels on rigid models are tied to the Adjust-O-Cut bar for automatic setting for each width of cut
    Depth stops are used for easy adjustment of depth Depth stops are used for easy adjustment of depth

    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).

    • Provides good trailing characteristics in transport.
Safety-trip standards for normal plowing conditions
    Safety-trip standardSafety-trip standard

    Safety-trip standards provide an economical means for protection—suited for areas without rocks:

    • No backing to reset, just raise
    • Shim-adjustable trip force
    • 2727-kg (6000-lb) nominal trip force (set at the factory)
    • Smooth surfaces for good residue flow
    • Few moving parts equals high reliability
Shear-bolt coulters suited for areas without rocks
    Shear-bolt coultersShear-bolt coulters

    Economical design of the shear-bolt coulters is suited for areas without rocks:

    • Few moving parts
    • Good depth adjustment range 
    • Good lateral adjustment range
Adjustable width of cut

    The operator can change the plow's width of cut to match the tractor horsepower and soil conditions.

    • Narrow in tough soil
    • Wider in lighter soil
    3710 Rigid Plow

    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.

    • Economical manual adjustment (turnbuckle is standard equipment)
    • Convenient hydraulic cylinder adjustment is optional
    • Pointer and decal allow returning to a predetermined width of cut
    3710 Flex Plow
    3710 Flex Plow3710 Flex Plow

    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.

High clearance handles heavy residue levels
    Frame clearance for residueFrame clearance for residue

    Excellent fore-aft and vertical clearance between standards (arrows above) allows the soil and residue to freely flow through the plow:

    • Both rigid and flex plows are designed to handle tall and heavy residue levels.

Scissor-type landing helps with tight turns on rigid models
    Scissor-type landing adjustmentScissor-type landing adjustment

    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:

    • Design uses minimum space, gives a clean-style appearance, and has a full range of adjustment.
    • Economical turnbuckle is used to make the adjustment.
    • Operator-supplied 76-mm x 203-mm (3-in. x 8-in.) American Society of Agricultural Engineers (ASAE) tie-bolt hydraulic cylinder may be used in place of a turnbuckle for in-furrow applications.
Adjustable-force cushion coulters available for rocky or normal field conditions

    Adjustable-force cushion coulters are suited for rocky or normal field conditions:

    • Excellent rosette depth adjustment range
    • Good lateral adjustment range
    • Separate down-force adjustment
    • Overload protection to prevent damage
Flex models are equipped with dual, staggered Walk-Over™ land wheels
    Land wheels have four adjustment positionsLand wheels have four adjustment positions

    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:

    • Depth stops are used for easy adjustment of the depth.

    Dual, staggered Walk-Over wheels are standard on flex plows:

    • Allow the plow to trail like a cart
    • Distribute weight evenly between both wheels
    • Minimize bulldozing in soft soil
    • Allow better residue flow
    • Walk over obstacles and across dead furrows
Light-draft NU bottoms permit high-speed plowing
    NU bottoms behind mainframe NU bottoms behind mainframe

    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.

    • Operators often find they can plow a gear higher than with competitive plows
    • Greater productivity and fuel economy
    • Speeds up to 10 km/h (6 mph)

    Available in 400-mm (16-in.) and 450-mm (18-in.) sizes with an unpolished finish.


    The maximum plowing depth are as follows: 

    Bottom maximum
    Plowing depth*

    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.

    Shares for NU bottoms

    Both the NU 400 and the NU 450 come standard with heavy-duty, full-cut shares.

    Variety of sharesVariety of shares

    A variety of shares are available through Parts to match the plowing conditions:






    NU400Regular, narrow cut


    NU400Heavy duty, narrow cut


    NU400Heavy duty, full cut


    NU450Heavy duty, narrow cut


    NU450Heavy duty, full cut (standard equipment)


    NU450500-mm over-cut (for use when wide widths of cut or complete slicing is required)


    NU450Hard-faced gumbo (for heavy soil conditions when penetration is a problem


    NU400Hard-faced (for areas where abrasive soil causes rapid wear of heavy-duty shares—not for use in rocks)


    NU450Hard-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.

    • Moldboard will not be forced upward by soil movement as much as NU 400.
    • Permits soil to push off easier for better scouring and lighter draft.

    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):

    • 13-mm (1/2-in.) wear, 89 mm (3.5 in.) remaining.
    Trashboards for NU bottoms

    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.
