1755 Drawn Planter

A 406-mm (16-in.) notched marker disk blade with a 102-mm (4-in.) wide depth gauging band is base equipment on folding markers. Notched marker disk blades are compatible with all tillage conditions but are recommended for no-till and high-residue mulch-till conditions. This marker uses a 44.45-mm (1.75-in.) square tube marker arm extension.

Folding markers are base equipment on the following planter model configurations:

1755 8Row30

1785 8Row30, 15Row15

Although not in base equipment, folding markers are available for the following integral planter configurations:

1705 6Row30, 6Row36, 6Row38, 6Row40, 8Row30, 8Row38, 8Row40, and all 10Row

1715 all rows

1735 all 12,13, and 15Row

The seed variable-rate drive provides the ultimate planting productivity by utilising one, two or three hydraulic motors (varies by model) to turn the seeding drive shaft. Hydraulic control of the seeding drive allows for on-the-go seeding rate changes right from the display mounted inside the tractor cab.

Combine this seeding flexibility with the map-based planting option, and seeding rates adjust automatically based on a prescription map.

Single- or dual-motor systems for variable-rate drives are available for all John Deere planters except the 1785 Rigid Frame. Dual- or three-motor drive systems are commonly used on larger (12-row and more) planters and offer the capability of half-width or three-section drive disconnect.

The VRD is available as a factory-installed option for all applicable planter models. Single- or dual-motor systems are available as field-installed attachments for most planter models; however, a three-motor VRD field-installed attachment is not available.

The seed VRD requires the SeedStar™ monitor and a radar input signal. Either tractor or planter radar may be used. Planter radar is ordered separately.

VRD offers the following advantages over common, contact-tire drive systems:

Almost instantaneous rate changes; there is no ramp-up or ramp-down of the system as in some competitive systems

Permits the operator to match seed population based on different soil types or irrigation practices

John Deere design that provides added operator safety by eliminating any possible drive creep found in some competitive variable rate drive systems

HALF-WIDTH DRIVE DISCONNECT

The half-width drive disconnect feature is excellent for the producer concerned with controlling seed costs. This feature helps the operator place seed in the desired area and limit the amount of costly overlapped planting.

The half-width drive disconnect allows the operator to turn off half of the planter at a time for planting end rows, point rows, etc. Variable-rate-equipped planters require two drive motors to utilise the half-width disconnect feature.

Integrated innovation--that is what operators will appreciate with the SeedStar 2 monitoring system and GreenStar™ 2 (GS2) Display. An increasing number of acres, combined with rising seed costs, drives the need to easily understand planter functions and monitor performance. It is all about making every seed count, and that is what SeedStar 2 delivers.

The SeedStar 2 monitoring system is a full-featured, colour seed population monitor used in conjunction with the GreenStar family of displays (Generation 4 CommandCenter™ controls with premium activation, GS 2630, GS 2600 Display, or the entry-level GS2 1800 Display). Conveniently, SeedStar 2 planting functions are fully integrated with the full spectrum of AMS applications—guidance, coverage maps, and field documentation can be shown all on one display.

When a SeedStar 2 system is used on a planter, there is no need for a ComputerTrak™ monitor. All vital planting information is displayed in one central, easy-to-read location.

The MaxEmerge family of row units has never seen a more versatile and efficient design than the MaxEmerge 5. The 5-family row units improve productivity, increase uptime, and lower the cost of ownership like never before.

The MaxEmerge 5 row unit was designed for improved performance and serviceability.

Delivering consistent and accurate fertiliser rates to each row is critical with any liquid fertiliser delivery system. The John Deere liquid fertiliser system utilises 12-port block manifolds to distribute flow equally to the opener or in-furrow application method. Liquid is distributed to each row through an 8-mm (0.3-in.) hose.

There are check valves at each row to ensure the system remains primed and flow stops immediately when the planter is lifted. An orifice is located in-line and provides the restriction needed to achieve desired system pressure for excellent rate accuracy.

This delivery system will operate between 15 psi and 90 psi, depending on the orifice size and rate. System pressure should not exceed 100 psi. Four orifice sizes allow operators to achieve a variety of rates, all with optimal system performance and row-to-row accuracy. See rate chart below for model-by-model minimum and maximum application rates.

An 80-mesh washable screen is in place between the tank and the pump. It is essential to have this screen (AA40216) and associated fittings in place ahead of the fertiliser pump even if not using a factory tank and quick-fill system. This screen is utilised to catch any blocks in the system caused by impurities in liquid fertiliser. It is not recommended to use the 50-mesh screen.
