2025 Kuhn HR 1030 Series HR 3530

The HR 1030 Series power harrows carry KUHN’s solid reputation into a new generation with updated features and better performance including a heavy-duty drivetrain, redesigned rotor, more rotor speeds and adjustable leveling bar.

The new HR 1030 Series power harrows carry KUHN’s solid reputation into a new generation with updated features and even better performance. Building on the success of their direct predecessors, the popular HR 1004 D series, the HR 1030 series models have a class-leading driveline rated up to 270 PTO horsepower with the most available rotor speeds in the industry. Newly designed rotors and lubed-for-life gear trough reduce power consumption for high tractor fuel efficiency. An adjustable leveling bar is standard equipment and helps the rear roller create an ideal seedbed in a wide variety of conditions. Other options including quick hitch brackets, stone deflectors, and more, help customize the machine to meet the needs of almost any operation.

Features may include:

Hitch

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.

All HR 1030 series power harrows feature a 1,000 rpm PTO with cam clutch protection as standard. The central gearbox includes an integrated oil pump and the top bearing receives fresh oil injection for extended life. The result is a class-leading power rating of up to 270 PTO horsepower on the HR 4530. The central gearbox is also offset to the rear to help keep the PTO shaft at a flatter angle to reduce wear.

Versatile & Reliable"

Switchable duplex gears in the central gearbox allow for two rotor speeds as standard. Including the factory set, a class-leading total of five gearsets are available. This wide range of rotor speeds allows operators to tailor the machine to the crop and soil conditions while still running at optimal PTO input speed for fuel efficiency, productivity, and ideal seedbed preparation.

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

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.

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.

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