Features
BASKET & DRUM
TIME-TESTED SEEDBED PREP
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.
MODEL 1645D
The basket-drum design combines an aggressive front basket with a 16" diameter rear rolling drum with 1 5/16" welded cleats that drive the drum through the field, while creating channels for enhanced water retention. Reversible scraper blades keep the drum clean during operation..
SOIL CONDITIONING
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.
BASKET CONSTRUCTION
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.
PIVOT ARM COVERS
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.
BEARINGS
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.
FRAME
SIZES
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.
TONGUE
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.
HORSEPOWER
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.
TRANSPORTATION
The main frame features 16" of ground transport clearance and utilizes 9.5L x 15 dual wheels and tires (11L x 15 duals on 5-section vertical fold) for exceptional transport stability.
POWDER COAT
The tongue, main frame and wings are powder coated in your choice of tractor red or green for a long-lasting, high-quality finish.
HYDRAULICS
The Rolling Harrow soil conditioner tillage tool is complete with all hydraulics, including couplers and protectors, to raise the transport wheels and fold the wings. All hydraulic hoses are rated at 3,000 PSI and are routed through the mainframe for longer life.
