 Adjustable Tine Angle
To match any field condition, the tine angle can easily be changed to one of five positions. The rear-mounted lever simply locks into place for quick adjustment, and the front bar is independently adjustable.
|
 Fine-Tune Tine Aggressiveness
The front row of harrow tines can be adjusted to be less or more aggressive than the other rows. Three holes (indicated by arrows in the photo) allow the user to make these fine-tune adjustments to fit the desired finish of their field.
|
 Adjustable Arm
The mounted harrow arm can be raised or lowered for the optimal height on any piece of tillage equipment. Three holes at the top of the spring rod allow for set height settings, while a nut at the bottom end of the spring rod offers incremental adjustments to fine-tune the fit.
|
|
 Free-Floating Tines
The free-floating tines are equipped with 1/2-inch stop bolts.
|
|
 Crossbar Leveling
Once the height of the harrow is set, the sections can be “tipped” to make level. This is accomplished by adjusting the crossbar within the harrow section. There are two ways to mount the harrow in order to change distance from the machine. Each position has a series of holes that allows the harrow to tilt relative to the arm.

 The Ideal Match
Get the benefits of harrow attachments no matter what tillage equipment you run. Whether it’s a big ag company or smaller one-off, Summers mounted harrows can attach to almost any piece of tillage equipment, regardless of manufacturer.
|
|
 Compression Springs/Bushings
Heavy-duty pressure springs help the tines achieve optimum soil penetration. The arms are also equipment with urethane bushings to absorb shock during transportation.
|
|
 3- and 4-Bar Harrows
Choose from 3- or 4-bar harrows for different levels of residue management and field finish.
|
|
 Locking Positions
The mounted harrows can be locked in the “up” position during operation when they’re not required.
|
|
 Nozzles
Five-head pinwheel nozzles spaced 20 inches apart come standard and are available with 80- or 110-degree combo tips with stainless steel inserts.
|
|
 Electronic Control System
A Raven 4400 system offers independent control of the seven boom sections. It automatically adjusts application rates according to the cart speed, which can be detected with the standard GPS sensor or by connecting the unit to the tractor’s performance monitor or GPS receiver. The controller also displays the actual gallons per acre applied, gallons per minute, total volume applied, remaining tank volume, time, total area worked, vehicle speed and distance traveled.

|
 Auxiliary Rinse Tank
Every Summers field sprayer comes with a 71-gallon side-mounted rinse tank, but this option allows you to add a second.
|
|
 Clean Load System
The 5.5-gallon chemical inductor system provides ground level, foam reduced filling of liquid and dry chemicals as well as flowable powders, inducting them directly into the top of the sprayer.
|
|
 Strainer Basket
Prevent foreign objects from entering the spray tank with a strainer basket.
|
|
 22-Inch Nozzle Spacing
You can opt for 22-inch spacing, rather than the standard 20-inch spacing.
|
|
 Foam Marker
Add a 25-gallon foam marker kit to mark your lines.
|
|
 Electronic Remote Control
Start and stop the sprayer anywhere within 100 feet of the control box for easy calibration and maintenance. This means you can turn the nozzles on and off while walking around the booms.
|
|
 Electronic Gauge Package
This add-on gives you in-cab pressure readings through the electronic control system.
|
|
 Control Grip
A joystick provides fingertip controls, so you can alternate circuits without changing hand positions.
