The Original from GÜTTLER
Prismenwalze® (prism roller). The roller with the golden hoofprint®.
The self-cleaning GÜTTLER roller for a seedbed that is firm below and loose and crumbly on top – from front presses to grassland equipment.
Firm below. Loose on top.
For reliable and rapid field emergence, the seed needs warmth, air and water – in as balanced a ratio as possible. That is what Fritz Güttler’s ideal seedbed stands for: firm below, loose and crumbly on top – fine soil below, coarse crumbs on top.

Self-cleaning
Unlike a Cambridge roller, the Prismenwalze® does not iron the seedbed smooth – and it cleans itself.
The prism points penetrate the soil and reconsolidate it below the seed zone. The seed lies on a firm, water-conducting seed zone, and valuable germination moisture is retained. Coarse crumbs on top protect against capping and wind erosion, heavy rain can soak into the soil, and the seedbed dries off and warms up quickly.
A seedbed that is “firm and fine on top”, by contrast, caps easily. That is why the widely used Cambridge rollers were out of the question for Fritz Güttler: they literally iron the seedbed smooth.
How the prism point moves
- It enters the soil vertically.
- A small horizontal movement backwards creates the sorting effect: fine soil trickles down, coarse crumbs rise to the top – similar to a harrow tine.
- It comes out vertically again – the seed stays in the soil.
The GÜTTLER prism ring has the typical pent-roof-shaped, serrated tread. Its points radiate the pressure in a wedge shape in all directions. This results in reconsolidation with a great depth effect, and the seed is very well connected to the capillaries.
The name
The golden hoofprint. Why the roller has this name.
Our grandfathers already valued the hoof action of sheep: winter crops were grazed by sheep in late autumn. This reconsolidated the seedbed, reduced the risk of winterkill, prevented capping and stimulated tillering before winter. On grassland, the hoof action creates a denser sward and brings the overseeded seed into firm contact with the soil.
The Prismenwalze® uses exactly this sheep’s hoof effect: 305 prism points per square metre have the same effect as a flock of sheep passing over the field – denser swards and firmly trodden-in overseeding on grassland, and an almost ideal soil structure on arable land.

Self-cleaning
Self-cleaning. Two half-rings, one ring pair.
Two half-rings of different sizes always work together in pairs: the smaller one sits on the shaft, the one that is 5 cm larger runs on the hub of the smaller one.
- In the soil, both are at the same level and exert the same ground pressure.
- As they roll, the larger half-ring is pushed 5 cm upwards, and the smaller one turns faster. This relative movement gives GÜTTLER rollers their self-cleaning power.
- In furrows, the large ring can drop 5 cm downwards – which ensures good ground contouring.
The ring pairs come in two sizes: Ø 33/38 cm and Ø 45/50 cm. On the MEDIANA with semi-synthetic rings, the smaller ring is fixed on the shaft and the larger one turns freely – the “fixed ring, freely rotating ring” principle.
SIMPLEX, AVANT and DUPLEX® work with prism rings of Ø 45, 50 or 56 cm. The SIMPLEX Prismenwalze® has non-contact scrapers made of spring steel in the gaps – easy to pull and without tedious readjustment. In the DUPLEX®, two Prismenwalze® rollers run offset one behind the other, which ensures excellent self-cleaning.
Thanks to self-cleaning, GÜTTLER rollers can also be used on moist soils. On wet, cohesive soils the prisms will of course still clog – but the soil build-up on the rings never goes beyond a certain level, and the seedbed stays firm below and loose and crumbly on top.

Reconsolidation
Reconsolidation. Loosen first, then reconsolidate.
When tractors became bigger and heavier and left deep tracks, Fritz Güttler drew the conclusion: “Loosen as deeply as necessary to level out the tractor tracks. Then reconsolidate to restore the water-conducting capillarity.” This made him the pioneer of reconsolidation. At first he often met with incomprehension – today reconsolidation has long been taken for granted.
What the Prismenwalze® achieves: it reconsolidates across the full width – through strong lateral pressure radiation, also behind the subsoiler and independently of rows (example SIMPLEX) – and leaves a well-settled seedbed with a lower risk of winterkill (example DUPLEX®).
The right timing
- Moist soil should first be allowed to dry off before sowing instead of being “stamped down” straight away; reconsolidation then takes place at sowing with a front roller. As soon as the soil turns grey, the GÜTTLER roller crumbles, levels and reconsolidates it very well – precious germination moisture is conserved.
- Before sowing, at the front (example MEDIANA): even seed placement, a firm water-conducting seed zone, reliable and rapid field emergence.
- After sowing, the roller also creates perfect soil contact, but the crop may then emerge more unevenly and later.
- With the front press, the soil is crumbled and reconsolidated in front of the tractor – at the rear, the power harrow no longer has to work it intensively.
How heavy should a roller be?
Experience shows that common sense should prevail when it comes to implement weights. Larger and heavier rings would be easy to design. But a larger diameter means a larger contact area and therefore less reconsolidation; a higher implement weight carries the risk of soil sealing and a lack of oxygen in the root zone.
Practical tip: Optimum reconsolidation for sugar beet drilling – MEDIANA 820 at the front, fine, firm and moist in the seed zone.
“As a rule, our soils do not suffer from a lack of reconsolidation, but from excessive compaction caused by heavy vehicles.”
Arable
On arable land. In use all year round.
The Prismenwalze® is a system roller for year-round use. GÜTTLER never actually set out to build field rollers – today the Prismenwalze® is used as a field roller before or after sowing.

Breaking crusts
After heavy rain, flooding or in spring, the Prismenwalze® breaks crusts in existing crops or new sowings and creates the desired fine, crumbly surface; rainfall soaks in faster and gas exchange gets going again.
-
Against the corn borer
On the MAYOR, the levelling bar “scalps” the maize stubble at the base; 305 prism points per square metre crush and break the stubble.

Grassland
On grassland. The grassland roller with the hoofprint.
The Prismenwalze® found its way onto grassland almost by chance: GÜTTLER wanted to test a new trailed roller and, for lack of free arable land, drove onto grassland. The roller’s “hoofprints” caught the eye. This gave rise to the GreenMaster system; at its heart is the GÜTTLER roller with its “golden hoofprint”.
What the Prismenwalze® does on grassland
- Damage to leaves and nodes strongly stimulates tillering.
- Overseeding in a single pass: the harrow opens the soil, the pneumatic seeder distributes the seed, and the roller with the golden hoofprint® “treads” it firmly into the seed zone.
- Turning on the spot without harmful friction damage – particularly important on grassland: on the trailed rollers, all prism rings are mounted in one row.
Grassland equipment with Prismenwalze®
- GreenMaster 250 / 300 with Mediana 25/30 or Matador 25/30.
- GreenMaster 600 / 750 Alpin: harrow at the front, Prismenwalze® (Matador, on the 250/300 Alpin also Mediana) with seeder at the rear.
- GreenMaster Compact: MEDIANA Prismenwalze® Ø 33/38 cm directly on the harrow, as a three-point implement.
- GreenMaster 600 / 750 / 800: with a coupled MAYOR, Master or OffSet® trailed roller; GreenMaster EcoLine 600: optionally the same.
- GreenMaster TINE SEED: with a coupled MAYOR or Master.
- MATADOR as a grassland roller at the rear.
Caution on wet grassland: on moist soil, heavy implements very quickly compact the soil – with a lack of oxygen in the root zone and stagnating growth.

SIMPLEX: special cast iron or Synthetic Ultra?
Special cast iron
- Break-proof, even in extremely stony conditions
- Very good crumbling of dry clay soils
- Ø 56 cm split: ring halves clamped without play on the 140 × 140 mm axle tube with four bolts – secure fit, easy to service
- Ø 56 cm on the SIMPLEX only for subsoilers, not for power harrows
Synthetic Ultra
- Very light
- The roller presses smaller stones into the soil; the prism ring yields elastically to larger ones
- Good self-cleaning · proven since 1995
- Limits: a high proportion of very stony fields, very sharp-edged stones
For the Ø 45/50 cm ring pairs, the wear parts list does not include rings made of Synthetic Ultra; the trailed rollers run as standard with a cast-iron Prismenwalze® Ø 45/50 cm.
MEDIANA, Ø 33/38 cm: the rings are available in cast iron, semi-synthetic and fully synthetic – cast iron for the “normal case”, semi-synthetic and fully synthetic to reduce weight, for light tractors. The working quality of the semi-synthetic rings is just as good as that of the solid cast-iron rings.

History
From the first ring to the divided rings. A brief history.
Fritz Güttler was looking for a roller that would reliably clean itself and match his idea of the ideal seedbed. Despite many setbacks, he developed a completely new type of roller with the patented Prismenwalze®. The granting of several international patents shows that it is an invention in its own right and not merely an improvement on existing things. The first patented GÜTTLER roller had a diameter of 32/35 cm. After that, the prism ring was developed further, generation by generation.

Questions
Frequently asked questions. About the Prismenwalze®.
What is a Prismenwalze® (prism roller)?
A Prismenwalze® (prism roller) is a roller for arable farming and grassland maintenance whose special prism rings imitate the hoof action of a flock of sheep. The soil is reconsolidated in spots while a loose, crumbly surface forms at the same time. This is why the self-cleaning GÜTTLER Prismenwalze® is also known as “the roller with the golden hoofprint®”.
Who makes the Prismenwalze®?
The original Prismenwalze® comes from GÜTTLER in Kirchheim unter Teck. Fritz Güttler developed the special roller principle and had it patented. “Prismenwalze®” is a protected trademark of GÜTTLER GmbH. GÜTTLER is therefore the inventor and original manufacturer of the Prismenwalze®.
What is the difference between a Prismenwalze® and a Cambridge roller or flat roller?
Cambridge and smooth rollers leave a rather evenly reconsolidated or fine surface. The Prismenwalze® works differently: it provides reconsolidation at depth and leaves coarser crumbs on the surface. This creates an optimal seedbed: firm below, loose and crumbly on top.
Is the Prismenwalze® suitable for grassland?
Yes. 305 prism points per square metre act much like the hoof action of a flock of sheep and stimulate tillering of the grasses. At the same time, overseeded seed is pressed in well and soil contact is improved. With the GreenMaster, harrowing, seeding and rolling can be combined in a single pass.
Which diameter is right – Ø 33/38, 45/50 or 56 cm?
Ø 33/38 cm (MEDIANA) is the medium-weight roller for the final pass, Ø 45/50 cm runs in the MATADOR and the trailed rollers, and the SIMPLEX is available with Ø 45, 50 and 56 cm. A larger roller diameter increases the contact area and therefore reduces reconsolidation.
Cast iron or Synthetic Ultra – which is better?
Special cast iron is break-proof, even on extremely stony land; Synthetic Ultra is very light and cleans itself well, but has its limits on very stony land and sharp-edged rock.
Can I replace individual prism rings?
Yes. Prism rings are available as wear parts in the groups Ø 33/38, Ø 45/50 and SX/DX; they are ordered through your GÜTTLER dealer. In extreme cases, the split 56 cm rings can be replaced without dismantling the roller.
Will a Prismenwalze® fit my power harrow?
The SIMPLEX Prismenwalze® is the trailing roller for most power harrows on the market. The mounting parts are only clamped, not welded – so the roller can also be transferred to another power harrow. GÜTTLER supplies the matching mounting parts on request, if you state the make, type and year of manufacture of the power harrow and seed drill as well as the working width and installation dimensions.
