Tillage | CP55 Chisel Plow

Model year 2027 new tool offerings

Overview

Starting in model year 2027, 2430s will no longer be available to order. To replace this lineup, we will now offer the new CP (Chisel Plow) Series in working widths ranging from 16’ 3” to 63’ 0”. The change is only in the naming, as there are no physical changes to the machine or its performance. The update makes ordering and support more efficient through a restructuring of option codes. Extra standards will no longer be available to order through whole goods. Standards are available to order through your normal parts channel. See table below for the updated base codes, model names, and working widths.

Finishing components

The CP Series offers different rear attachment options to meet the unique agronomic needs of each producer. Producers have a choice of two rear attachments on theCP Series.

Knife-edge hydraulic rolling basket with internal basket scraper

Knife-edge rolling basket for the CP Series

Internal basket scraper

The knife-edge rolling basket for the CP Series is made of hardened steel and handles rock strikes and adverse conditions well. The ease of down pressure adjustability allows the tool to adapt to changing field conditions. The internal basket scraper allows for a uniform field finish in wet conditions because baskets do not need to be raised out of the ground to avoid plugging; they can remain in the ground 100 percent of the time.

The John Deere CP Series offers an active hydraulic rolling basket that gives the operator wide-ranging adjustability for a variety of conditions. The drawbars and rolling basket on the rear harrow are built with strength in mind for the demanding fall conditions. The system was designed to have the ability to run the rolling baskets in three different positions to finish and level the soil:

Raised: allows the operator to raise the rolling baskets in harsh, muddy conditions
Float: allows the operator to float the rolling baskets to lightly fluff soil
Apply down pressure: allows the operator to adjust the basket pressure to provide consistent contact with the ground, provides a firm seedbed, and shatters root balls

The hydraulic rolling basket is offered with the knife-edge basket, which is the best for heavier, wet soil.

Coil-Tine Chisel Plow Harrow

240 Coil-Tine Chisel Plow Harrow

The Coil-Tine Chisel Plow Harrow is designed specifically for the CP Series. Harrow performance has grown increasingly important over the last few years as soil profile finish and residue-handling capability are on the top of the list for producers. Both attributes are standouts on this heavy harrow.

Excellent residue-handling capability

CP Series

The CP Series has excellent residue-handling capability in primary tillage at all residue levels.

Typical percentages of residue cover remaining from the CP Series are listed in the following table. The percentages do not consider variables such as the condition of the residue, speed, and soil type.

For machines with 305-mm (12-in.) spacing:

Starting residue cover (percent)	Remaining non-fragile* residue cover (percent)				Remaining fragile** residue cover (percent)
Starting residue cover (percent)	406-mm (16-in.) sweeps	51-mm x 356-mm (2-in. x 14-in.) chisel point	102-mm x 368-mm (4-in. x 14.5-in.) shovel	406-mm (16-in.) sweeps	51-mm x 356-mm (2-in. x 14-in.) chisel point	51-mm x 356-mm (2-in. x 14-in.) chisel point	406-mm (16-in.) sweeps	51-mm x 356-mm (2-in. x 14-in.) chisel point

Proven frame construction

3.4-m (11.17-ft) four-bar frame

Operators are requiring faster field working speeds, larger implements, and tractors because of a dramatic increase in farm size. The market is asking for and receiving tractors with more torque, more weight, and more horsepower.

Accommodating 600 engine horsepower tractors requires more from implement frame and hitch components, including thicker frame tubes, additional diagonal bracing, and frame gussets.

The frame is constructed of continuous 102-mm x 102-mm (4-in. x 4-in.) cross members inserted through 51-mm x 152-mm (2-in. x 6-in.), 76-mm x 152-mm (3-in. x 6-in.), and 102-mm x 152-mm (4-in. x 6-in.) fore-aft members. The mainframe boasts a structure made up of 102-mm x 152-mm (4-in. x 6-in.) fore-aft tubes.

The large frame member sizes, joint welds, and wheel module placement adds to the structural integrity, providing a stable front-to-rear and side-to-side operation.

Frame construction offers:

Consistent operating depth
Level operation
Restricts frame dip
