01Front presses

Front presses. Active, not ballast.

Levels, crumbles and reconsolidates as a front device – the tractor sinks in less and the power harrow can work shallower. Actively working weight at the front instead of dead front ballast.

Benefits in the field

Active front implement. Instead of dead weight.

You save energy, and the power harrow works the soil surface in excellent conditions – you don't need any more horsepower than before.

  • One pass fewer

    Breaks up heavy plough clods and replaces the furrow press – an optimum seedbed with fewer passes.

  • Balanced axle loads

    The tractor runs on a level, pre-consolidated track – greater driving comfort, less sinking in.

  • Preserves valuable water

    Fine soil in the seed zone, the best possible seed embedding, coarse crumbs on top to protect against capping.

  • Less wear

    Minimises wear and fuel consumption; a well-settled seedbed with a lower risk of winterkill.

Good to know

Good to know: axle loads.

A calculation example: a 100 hp tractor (unladen weight 5,300 kg) with a 3-metre power harrow, a mounted seeder and 500 kg of seed – at work in the field.

Front weight 685 kg

Front axle
3,060 kg
Rear axle
2,835 kg
Result
The tractor becomes nose-heavy – the heavily loaded front axle constantly struggles over the rough furrow.

DUPLEX® with tined unit 1,250 kg

Front axle
2,084 kg
Rear axle
3,216 kg
Result
The tractor runs unburdened on a level, pre-consolidated track and sinks in only minimally.

Mounting implements must not cause the permissible axle loads, total weight or support loads to be exceeded – observe the road traffic regulations (in Germany: StVO/StVZO).

Which front press for which soil?

What matters is how the soil breaks up when ploughed – loose and friable, cloddy or very cloddy.

Origin

The Original. Since 1978.

The Prismenwalze® principle

Firm below. Loose on top.

Fine soil below embeds the seed and connects it to the capillary water supply. Coarse crumbs on top protect against capping and wind erosion. Fritz Güttler’s ideal seedbed is still built into every GÜTTLER machine today.

  • 01Firm below Seed placement on a firm seed zone with capillary water flow.
  • 02Loose on top Coarse crumbs on top – protecting against capping and wind erosion.
  • 03Self-cleaning Unlike a Cambridge roller, the Prismenwalze® does not iron the seedbed smooth – and it cleans itself.
The Prismenwalze® principle

  1. 1978: The Prismenwalze®

    The first patented GÜTTLER roller, Ø 32/35 cm. Several international patents confirm it: an invention in its own right, not merely an improvement.

  2. 1999: Prism rings Ø 56 cm

    Divided, made of break-proof special cast iron, bolted to the 140 × 140 mm shaft without play using four bolts.
