Case IH - Model True-Tandem 345 - Disk Harrows


Case IH True-Tandem™ 345 disk harrows provide true-tandem technology for straight, easy pulling and maximum pass coverage. Ideal for primary tillage, seedbed preparation or chemical incorporation, True-Tandem disks feature durability and low maintenance. Choose a rigid-frame or cushion gang mounts.

Built with Agronomic Design features throughout

The unique symmetrical design of the True-Tandem 345 offers easy pulling and high performance seedbed preparation, even in the roughest of fields. Stubble-resistant tires add to the disk harrow’s rugged profile. These optional stubble-resistant tires are larger—340/55-16 on smaller models and 380/60- R16.5 on larger machines—for enhanced flotation and reduced soil compaction.

Prep your soil for next season's crop

The 345 slices through tough residue, partially mixes with soil and anchors it to the soil. These actions speed the decomposition process of residue which contains valuable nutrients for the next season’s crop.

Larger tires = less compaction

Larger tire option means a larger footprint and less root-inhibiting compaction in the field due to wheel tracks.

Perfect blade size

Blades are 22 in. diameter, right-sized to handle residue and create the perfect seedbed.

Reduce the number of clods

Optional double-formed bar reel with active hydraulics rolling basket breaks up clods and conditions the field. Reduction in the number of clods leads to a much better seedbed. Active hydraulics mean constant downpressure, adjustable from the front of the machine. The reel also may be positioned in float mode, or raised entirely in wet corners of the field.

Even Distribution

The optional coil-tine harrow feathers and evenly distributes residue.

Creates a smooth Seedbed

Front and rear sets of blades are indexed exactly to create a smooth seedbed. Factory-set 18 degree blade angle is perfect for a superior finish. The angle matches with the blade concavity to leave a level seedbed and virtually no horizontal compaction layer (unlike competitive units) since the blade does not ride on the back side.

Rugged and Productive

Fall & Spring Use

The 345 Seedbed disk may be operated in the Fall for residue sizing and mixing; and in the Spring for creating the perfect seedbed.

Low Maintenance

Reduced maintenance requirements, due to the addition of more greaseless bearings, keep you in the field longer.

Narrow Transport

Improved more narrow transport dimensions means less time traveling from field to field.

First In The Field

The optional stubble-resistant tires are 340/55-16 on working widths up to 28 ft.; and large 380/60-R16.5 for working widths of 31 ft. and 34 ft. The larger footprint and stubble-resistant features allow you to be first in the field.

Adjustments from the Cab

Single-point depth control allows easy adjustments from the cab.

Instant leveling capabilities

Hydraulic front-to-back leveling (optional) allows quick operator reaction to changes in field conditions.

The best line of vertical tillage tools just got better

The 345 is the latest in a long line of excellent Disk Harrow performance you have come to expect from the leader in Disk Harrows: Case IH

LED Lights

LED lights are brighter and last longer than incandescent lamps. The Class 3 powder coat paint finish retains color longer and is more resistant to scrapes and scratches.

Stand Up to Tough Use

The pull-through frame design with heavy duty tubing stands up to tough use.

Stubble-resistant tires

Stubble-resistant tire option means less chance of tire damage in tough field conditions.


All welded cylinders add reliability to the hydraulic operations.

Earth Metal Blades

Earth metal blades provide increased durability. Earth metal differs from conventional blades in that it does uses new steel and other alloys resulting in a much tighter tolerance for the resulting alloy. Earth Metal is also an improved process which includes quenching the blade while still in the die. This results in a blade that holds its shape better and is much more ductile and resistant to breaking or bending.

Rear Reel Basket

The optional rear reel basket has formed bars for additional strength.
