 HR 1030 series models are compatible with Cat. 2 and 3 hitches. Additionally, Cat. 4N quick hitch adapters are available as a field-installed option.

Central Gearbox and Driveline

Versatile & Reliable"

Switchable Rotor Speeds

Gear Trough & Rotor Drive

The sides of the main gear trough are constructed from 5/16” (8 mm) thick steel for outstanding structural rigidity. Forged-steel, treated gears have a convex shape to transmit all of the drive forces at the center of the upper bearings. These large bearings are preloaded with a spacer, while the lower bearings are held and protected by a one-piece housing that is 28 mm thick. The milled cover and cassette seal keep out contamination that could damage the gears or bearings. The main trough is lubed-for-life with extreme-pressure grease.

Create the Ultimate Seedbed

Blades & Blade Holders

All HR 1030 series power harrows come standard with blades 12.4” (315 mm) long and 0.63” (16 mm) thick. These blades are designed to reduce power requirements while working up to 9.8” (25 cm) deep for optimal seedbed preparation in a variety of crop applications. Optional DuraKUHN hard-coated blades offer improved durability and lifespan in abrasive soil conditions.

Round, flat blade holders are positioned with significant clearance below the trough. Fast-Fit technology promotes quick and easy blade changes, increasing critical uptime in tight tillage windows.

Three Available Roller Options

With three different roller options to choose from, the HR 1030 Series power harrows are suited to fit any commercial-sized operation’s needs.

MaxiPacker Rear Roller
The MaxiPacker rear roller comes standard on all HR 1030 series models. With an overall diameter of 21” (535 mm), it is a versatile roller that performs well in most soil conditions. To help improve performance in wet and sticky ground, scraper plates located between the rows of studs keep the roller clean.
MegaPacker Rear Roller
The optional MegaPacker rear roller is a similar design to the standard MaxiPacker, but with an increased overall diameter of 23.2” (590 mm). This helps reduce power requirements when working in tougher conditions.
MaxiCrumbler
The optional MaxiCrumbler rear roller is 20.5” (520 mm) in diameter. It is best suited to finishing dry soils.

Leveling Bar

The standard leveling bar mounted behind the rotors helps to smooth out the soil so the roller at the rear of the machine can finish creating the optimal seedbed. The leveling bar’s depth is adjusted mechanically with an easy-to-use crank for raising and lowering.

The leveling bar also features three manually-adjusted angles depending on conditions and the seedbed finish desired. The “trailing” position is best suited to shallow depths and higher speeds; the middle position provides the best leveling; and the “forward” position pushes material back toward the rotors for maximum clod breakup.

Depth Control

Mechanical depth control comes standard on all HR 1030 series models and allows the operator to fine-tune the working depth by moving a series of pins. For even greater comfort and ease of use, optional hydraulic depth control allows the operator to stay in the tractor seat when making adjustments.
