Features may include:

The Unverferth Rolling Harrow soil conditioner has been proven in the field for more than 35 years. While others imitate this time-tested product, none can duplicate the innovative features and optimal performance of the Rolling Harrow.

The double basket design combines an aggressive front basket with forward-angled blades that dig into the soil and propels larger soil clods into the rear basket with rearward angled blades that firm and condition the soil.

The high-clearance, arched and oscillating double basket or basket-drum frame features a free-floating design to ensure uniform soil conditioning in a wide variety of field terrains and soil types.

Models 1645 and 1645D feature a lead 16" diameter robotically welded basket with a 2 3/8" center shaft providing full-width basket support and are ideal for pulling at higher tillage speeds behind vertical tillage tools.

The double basket and basket-drum mounting arms feature pivot covers that prevent rocks and debris from accumulating, which ensures the basket oscillates and follows ground contours.

All baskets and drums on the Rolling Harrow soil conditioner feature patented 4-bolt greaseless bearings with a 1 1/8" square bore that can withstand heavy side-load stress during high-speed turns and triple lip seals with an exclusive shouldered construction that prevents the seals from reversing, keeping out dirt and debris.

The Unverferth Rolling Harrow soil conditioner models 1645 and 1645D are available in sizes ranging from 26’ up to 59’ and feature a 12’ or 15’ base with a cross- or 5-section vertical-fold design depending on size.

The oversized 5” x 5” adjustable length tongue can be extended from 10’ 2” to 19’ 2” on 12’ base models and from 12’ 10” to 21’ 10” on 15’ base models which provides a generous turning radius.

Depending on field conditions, generally 1 to 2 horsepower per foot of Rolling Harrow is required and minimal weight is added to the lead tillage implement for reduced stress.
