The field cultivator sweeps are designed to lift the soil and the sweeps are designed to aerate the soil. The springing back of the shank allows the sweep to travel through various soil conditions and the springing back of the shank allows the sweep to evenly distribute the soil.
The stacked construction of the field cultivator frame provides the flexibility in order to follow the contours of most field conditions. In addition, the wings can pivot eight degrees downward and the wings can pivot sixteen degrees upward during operation.
The positive effects of using a field cultivator include the following items:
- Contact between the soil and the seed is increased.
- The soil warms faster.
- Elimination of live weeds
- Incorporation of fertilizer and herbicide
- Activation of herbicide
- Leveling of the soil
- Operation in moderate residue and high residue
The benefits that are listed will enhance the yields of your crops.
The field cultivator can be used to perform multiple benefits in one pass. Incorporation of chemicals during preparation of the soil for planting is one example. This eliminates an additional tillage after the spraying is completed.
Combining field operations provides the following benefits:
- Reduction of cost
- Reduction of compaction
- Reduction of time in the field
The TL5 Series Field Cultivator is currently available in eleven models with operating widths from 30 feet to 50 feet.
The TL5 Series Field Cultivator are designed to meet the customer needs in the following ways:
- Precision of depth control in variable terrain
- Consistent leveling and uniform finish
- Precise adjustments
- High flow of residue
- Multiple choices of harrows
- Storage location for hydraulic lines
- Cushion-hitch
- Long, narrow, shaped hitch (A-frame)
Optional Equipment
The field cultivator can be equipped with the following optional items:
- True floating hitch
- Hitch (Trailing behind)
- Choice of two types of shanks
- Multiple choices of harrows
Shanks
The lower section of all shanks is 5/8 inch wide. This prevents the buildup of residue on the shank.
The bottom of the shank has a 47 degree angle for mounting the sweeps.
The field cultivator can be equipped with a 209-5042 S Shank or a 209-5043 C Shank.

The 209-5042 S Shank has the following advantages:
- Standard item
- Vibrating action
- Few parts to wear
- Rugged design
- Two-piece design

The 209-5043 C Shank has the following advantages:
- Optional item
- 86 kg (190 lb) of force at the point
- Stiff action
- 254 mm (10 inch) trip for obstacles
The field cultivator is available with the 6 inch spacing of the shanks or 8 inch spacing of the shanks. The 6 inch spacing provides a radius of 24 inches around each shank and the 8 inch spacing provides a radius of 32 inches around each shank.
Sweeps
The stem on the sweeps must have a 47 degree angle in order to mount the sweep on the shank.
The field cultivator can be equipped with sweeps that are 9 inches wide or 10 inches wide.
Operating Speeds
The rated speed for operation of the Field cultivator is between 5 mph to 7.5 mph. However, rough field conditions or excessive debris may require a slower operating speed.
Horsepower Requirements
For typical field conditions, the field cultivator will require 5 to 6 drawbar horsepower per foot of operating width.
The required drawbar horsepower will vary according to the following items:
- Field conditions
- Type of harrow
- Additional towed implements
Operating Depth
The field cultivator is designed to operate as deep as 127 mm (5 inch).
Make sure that the depth of tillage is suitable for the operation that is being performed. Incorporation of chemicals requires a shallow depth of tillage to keep the chemical in the top 3 inches of the soil.
Phasing the Implement
The hydraulic cylinders that are used on the implement should be phased periodically during tillage.
Reference: See Operation and Maintenance Manual, "Hydraulic Cylinders - Phase" for additional information.
Maintenance Locks

Maintenance locks are provided in order to mechanically lock the hydraulic cylinders in the raised position. The maintenance locks are red and the maintenance locks have a notice that directs you to the Operation and Maintenance Manual.
The maintenance locks should be used when you are performing maintenance in the raised position on the implement. If the wings are unfolded, use a suitable jack to support the wings.
Storage locations for the maintenance locks are provided on the implement in order to allow the service locks to be available at all times.
- Raise the implement. Make sure that all of the hydraulic cylinders for the center section are completely extended. If equipped, the hydraulic cylinder for the floating hitch will extend first.
- Set the parking brake on the tractor and stop the engine.
- Remove the maintenance locks from the storage positions and install the locks on the hydraulic cylinders that raise the center section and the hydraulic cylinder that locks the floating hitch. See Illustration 3.
- If the wings are unfolded, use a suitable jack stand to support the wings in the raised position. Position the jack stand in order to support the frame of the wing.
- Remove the maintenance locks from the storage positions and install the locks on the hydraulic cylinders that raise the center section and the hydraulic cylinder that locks the floating hitch. See Illustration 3.
- Move the hydraulic control valve to the FLOAT position and allow the cylinders to retract against the maintenance locks.
