Roller (agricultural tool)

A Field roller is an agricultural implement for reconsolidation ( compression ) of about loose soil as well as for the fragmentation of coarse clods. Field Rollers work primarily due to their high weight, and secondarily because of their profile shape. They were once made of wood and stone, since the end of the 19th century almost entirely of iron. In addition to the crumbling and compression, they often have an important function for depth control of tillage equipment, as they always roll over the soil surface.

Roll forming

A distinction is smooth rolling and napping rolls. They are available in different versions. These rollers are used as a trailer for other agricultural equipment, such as harrows or cultivators.

Roll smooth

• The smooth roller is used primarily for leveling of grassland.
• The packer roller for stripe-shaped consolidation of two seed rows per tire with low passive slip.
• The wedge ring roller for stripe-shaped reconsolidation of a seed row per each wedge ring.

Napping rolls

• The Cambridge Roller consists of lenticular cast-iron rings, which are mounted on an axle.
• The Crosskillwalze is also called Scholl breaker. Your slices are occupied at the outer periphery with prism-shaped teeth. The side bolsters of the discs have teeth.
• The Cambridge roller consists of two different alternating rings: rings with narrow prism- shaped teeth and wide rings with tapered washers.
• The spiked roller.
• The Furrow is a special form for the compression of deeper soil layers. The packer roller is attached to a plow or running in front of a front-mounted drill combination.
• The Prismenwalze ( for a manufacturer often called Güttlerwalze ) destroyed rough lumps and sorts the ground after coarse and fine fractions.
• The dipstick tube roller.
• The ring gear roller.
• The cutter roller.
• The die roll.

Of all the forms of the Cambridge roller in solo mode is now the most common. It was developed in the 19th century in England and consists of alternating each with a smooth ring and a serrated ring. The jagged ring has intentionally a large bearing clearance, thereby irregularly moves at work and thereby prevents the roller from becoming clogged with soil as a whole, creating a better self-cleaning is achieved.

The smaller counterpart is the garden roller.
