Benefits · 8 highlights

The roller with the golden hoofprint®.

The MAYOR shows its strengths all year round: rolling before and after sowing, breaking crusts, rolling frost-heaved crops, establishing undersown crops, maintaining grassland and helping to control the corn borer.

“Reliable technology that quickly pays for itself!”

GÜTTLER

One roller. Twelve months of work.

  • Prismenwalze® of the MAYOR 640 on grassland, prism rings and transport wheels from a low angle
    01 Prismenwalze®

    Unrivalled self-cleaning

    305prism points per m²

    Two half-rings of different sizes work in pairs: the larger one runs on the hub of the smaller one and pushes upwards by 5 cm as it rolls – this relative movement cleans the roller.

  • MAYOR behind the tractor on a freshly drilled field: transport wheels, frame with GÜTTLER lettering and Prismenwalze®
    02 Manoeuvrability

    Manoeuvrable like no other

    90°Steering angle without collision with the drawbar

    All prism rings run in line – turning on the spot without harmful friction damage. Hitching to the lower links places the pivot point behind the tractor.

  • Unfolded MAYOR rolling winter cereals, Prismenwalze® and belt tensioning on the frame
    03 Ground contouring

    Three sections follow the ground

    The folding joints allow the side sections to swing up or down. The hydraulic pressure compensation transfers the weight of the centre frame section evenly to the side sections.

  • MAYOR 770 in transport position behind the tractor, side sections folded forwards
    04 Road transport

    40 km/h on the road

    40 km/hwith EU type approval

    EU type approval as standard – the basis for the general operating licence (ABE). Hydraulically folded, the MAYOR has a transport width of 2.36 m.

  • MAYOR rolling winter wheat for growth regulation: Prismenwalze® and frame with GÜTTLER lettering in the young crop
    05 Tillering

    Rolling instead of growth regulators

    Rolling spring barley up to growth stage EC 32: on average one additional tiller per plant, stronger roots, more uniform crops – as an alternative or addition to growth regulators.

  • Aerial view: MAYOR rolling a frosted catch crop in freezing conditions
    06 Catch crops

    Rolling down catch crops

    The prism points kink the stems and damage the cell walls – with alternating frost, roll twice at an interval of 2⁠–⁠3 weeks. The soil cover remains as erosion protection.

  • MAYOR behind the tractor on a harvested maize field, the Prismenwalze® breaking the maize stubble
    07 Field hygiene

    Controlling the corn borer

    The prism points strike the maize stubble against the hard ground, crushing and breaking it. The stubble decomposes faster and the corn borer cannot overwinter.

  • Tractor with GreenMaster and coupled MAYOR during grassland maintenance on a slope
    08 Grassland

    Can be combined with GreenMaster

    Levelling, aerating, scarifying, overseeding and reconsolidating in a single pass: for professional grassland maintenance, the MAYOR can be coupled to a GreenMaster at any time.

Applications · arable land and grassland

The 12-month roller.

In use from January to December: rolling down catch crops, rolling crops, maintaining grassland, preparing seedbeds, working oilseed rape stubble and controlling the corn borer.

Suitable soils

Arable farming
Rolling before and after sowing, breaking crusts, rolling crops, corn borer control
Grassland
Stimulating tillering, soil contact for overseeding, levelling molehills (with levelling bar)
  1. 01

    Rolling crops

    Press down frost-heaved winter crops in early spring: the roots regain contact with the soil moisture and tillering is stimulated.

  2. 02

    Breaking crusts

    Break up crusted, silty soils so that gas exchange and infiltration can start again. Drive slowly, no faster than 6 km/h.

  3. 03

    Grassland maintenance

    Like the hoof action of grazing livestock: the prism points stimulate the sward to tiller and ensure soil contact for the overseeding.

  4. 04

    Rolling before and after sowing

    Firm and fine below, loose and crumbly on top: the seedbed retains valuable germination moisture and protects against capping and erosion.

The Original Since 1978

The MAYOR rolls with the Prismenwalze®. The Original. Since 1978.

305 prism points per square metre have the same effect as a flock of sheep walking across the field: denser swards and well trodden-in overseeding on grassland, and ideal soil structure on arable land. The Prismenwalze® is the roller with the golden hoofprint® – the original from GÜTTLER, since 1978.

The first MAYOR series has proven itself in considerable numbers since 2005.

Frequently asked questions

Good to know.

Why not larger diameters and more weight?

Larger and heavier rings would be easy to design. But experience shows that our soils do not usually suffer from a lack of reconsolidation, but from excessive compaction caused by heavy vehicles. That is why implement weights should be kept within sensible limits.

What should I bear in mind when rolling in spring?

First wait for suitable weather: when you knead the soil in your hand, it must not form “sausages”. There should have been no frost for 2–3 days before rolling, the daytime weather should be warm and good for growth, and there should be no night frosts for approx. 2 weeks afterwards.

How do I manoeuvre in tight spaces?

The roller can be lifted on its transport wheels in an instant at any time. This lets you reverse into corners or cross a farm track to the next plot without any problems.

How do I park the MAYOR for a longer period?

Take the load off the wheels and lower the roller until all prism rings rest on the ground. This prevents flat spots on the tyres, and the roller stands securely even on sloping ground.

    Rolling cereals in spring

    The Prismenwalze® stimulates tillering and breaks up light capping – provided there is no risk of frost before or after rolling.

    Catch crop management

    Minimum soil cover under the CAP, dense multi-species stands, rolling at the right time: how an obligation becomes a benefit for the soil.

    Practical tip · February 2024

  • Prismenwalze® on maize stubble – close-upAutumn
    • Maize
    • MATADOR

    Corn borer control

    At harvest, around 70% of the larvae are below the second node – so the maize stubble needs to be snapped and crushed and the root crown damaged.
