Benefits · 8 highlights

The professional roller for arable land and grassland.

Centre-mounted pendulum frames in a trailing arrangement – only from GÜTTLER. These heavy, wide professional rollers are extremely robust and safe on public roads, yet as versatile and manoeuvrable as every GÜTTLER trailed roller.

“Vigorous crops – reliable yields!”

GÜTTLER

Robust, manoeuvrable, versatile.

  • Master 640 with four pendulum frames at the edge of a field: the roller sections follow the transition from arable land to meadow
    01 Ground contouring

    Four pendulum sections

    4Pendulum elements with 3D ground contouring

    The four centre-mounted roller sections adapt superbly to the ground and precisely follow every unevenness.

  • Master with FlatSpring during seedbed preparation on a ploughed field
    02 Front implement

    FlatSpring for levelling

    Optional for levelling and crumbling: the angle of the sprung tools is hydraulically adjustable – even on the move.

  • Harrow with seeder from the GreenMaster system, coupled with the Master 770, overseeding grassland
    03 Modular system

    Combines with the GreenMaster

    The Master can be coupled to the GreenMaster 600, 750 and 800 – the roller’s hydraulics and lighting are connected directly at the GreenMaster.

  • Master 640 rolling a rough, cloddy field – each section follows the soil surface
    04 Stony soils

    Gives way to large stones

    The pendulum frames ride over even large stones without breaking the prism rings – break-proof even in very stony conditions.

  • Master 640 rolling winter cereals in early spring
    05 Smooth running

    Smooth running, even at high speed

    The roller sections are arranged to trail – so the Master runs smoothly, even at high speed.

  • Master 770 with four pendulum frames on grassland on a slope
    06 Manoeuvrability

    Turning on the spot

    All roller axles are in line: the Master turns on the spot – without friction damage and without harming valuable crops.

  • Master 640 lifted onto its transport wheels, ready to reverse into a corner
    07 Manoeuvring

    Onto the transport wheels in no time

    To reverse, you can lift the Master onto its transport wheels at any time – extremely manoeuvrable, even in tight corners.

  • Lower-link hitch of the Master 640 on the tractor at full steering angle
    08 Hitch

    Hitch beam behind the wheels

    The hitch beam sits behind the tractor wheels and allows full steering angle – no collision with the drawbar and no towing jaw support loads to worry about.

Applications

The all-season machine.

For arable land and grassland: rolling before and after sowing, rolling frost-heaved winter crops, stimulating tillering – also ideal for grassland management.

Suitable soils

Arable land and grassland
All-round machine for arable farming and professional grassland maintenance
Stony soils
break-proof even in very stony conditions
Moist soils
can also be used on moist soils thanks to the self-cleaning effect
  1. 01

    Rolling before and after sowing

    Firm and fine below for the best seed embedding, loose and crumbly on top as protection against capping – valuable soil moisture is retained.

  2. 02

    Rolling winter crops

    Press down frost-heaved crops in early spring: the roots regain contact with the soil moisture, and injuries to leaves and nodes stimulate tillering.

  3. 03

    Grassland maintenance

    Roll winter-killed swards, stimulate tillering and bring overseeding reliably into contact with the soil – with or without GreenMaster.

  4. 04

    Corn borer and catch crops

    Roll down and split maize stubble directly after harvest; roll down catch crops at flowering at the latest – before the stems become woody.

The Original Since 1978

The Master rolls on the Prismenwalze®. The Original. Since 1978.

The Prismenwalze® (prism roller) is the roller with the golden hoofprint® – the original from GÜTTLER, since 1978. Two half-rings of different sizes work in pairs: the smaller one sits on the shaft, while the one that is 5 cm larger runs on the hub of the smaller one – this relative movement produces the self-cleaning effect. 305 prism points per square metre act like a flock of sheep walking across the field.

Frequently asked questions

Good to know.

Why not larger and heavier prism rings?

It would be easy to design larger and heavier rings. But experience shows that our soils do not usually suffer from a lack of reconsolidation, but from excessive compaction caused by heavy vehicles. To avoid literally “letting the air out” of valuable soils, implement weights should be kept within sensible limits.

Can the drawbar collide with the tractor during tight turns?

No. The hitch beam sits behind the tractor wheels and therefore allows full steering angle; the roller’s pivot point is behind the tractor.

Does the Master have to be lifted to turn at the headland?

No. Because all roller sections are arranged in line, you can turn on the spot in the working position without the roller causing friction damage. Please reduce speed when turning.

Which hydraulic connections does the Master need?

Two double-acting spool valves for folding and the transport wheels. With FlatSpring, two more are needed for folding and angle adjustment; a pneumatic seeder with hydraulic fan needs one single-acting spool valve and a pressure-free return.
