Soil cultivation - Row independent soil cultivation | GR 300 / GR 360

For a fine crumbled soil cultivation on heavy soils.

The rotary tiller type GR 300, mounted in the rear or in the front of the tractor, is suitable as a full width tiller for an optimum seedbed preparation for the cultivation of various vegetables and potatoes. An ideal prepared seedbed is the prerequisite for optimum development of the seed resp. planting tubers. Thanks to intensive soil cultivation, the horizon for rooting is optimally prepared so that undisturbed growth of the crop can be ensured. The large number of tines and the high speed of the rotor produce a well crumbled soil structure in fields without stones. With its smaller rotor diameter the rotary tiller type GR 300 requires less tractor power as the rotary hiller GF 400. The combination with a GL 420, GL 430 or GL 420 Exacta is also possible.

Variable use

The GR 300 may be conventionally used as a rear-mounted rotary tiller for crushing clods and trash.

The ideal combination

The GRIMME Rotary Tiller GR 300 with front attachment, is ideally suited to be combined with a trailed or mounted 4-row potato planter. Convenient especially for short headlands and smaller acreage, a compact tractor implement combination is available for these requirements.

Combined plant protection

Tank system TS 420 on the GR 300 at tractor front. Authorized for liquid chemicals to be applied onto the seed potatoes and/or into the furrow

The ideal seedbed

Full-width soil cultivation for optimum seedbed preparation.

Combining work steps

Soil cultivation, planting and ridge shaping in a single pass.

Benefits

  • General benefits
    • full width tilling for an optimum seedbed preparation for potatoes or other vegetables
    • Smaller rotor diameter for a reduced power requirement compared to conventional rotary hillers
    • the drive shaft is fitted with cam shut down clutch for low-wear overload protection, even when in heavy conditions with stones and trash (compared to a conventional friction clutch)
    • Spring loaded housing for less soil sticking
    • Reinforced gearbox for up to 325 HP tractor power
  • Rotary Tiller GR 300 with front attachment:
    • When mounted on the front of a tractor the machine works great in combination with a rear mounted potato planter. The combination of soil cultivation and planting in a single pass can significantly reduce running costs and ground compaction.
    • The soil retention plate with integrated ridge shaper, to be used in front of the tractor, this avoids re-compaction of the loosened soil by the following tractor wheels.
    • Tine comb for the GR 300 in front mounting, to crumble clods for the following rotary tiller
    • The GRIMME tank system TS 420 is optionally available for the GR 300 in front attachment (2 x 200 l, consider the tractor lifting power)
  • Rotary Tiller type GR 300 rear-mounted:
    • GR 300 for rear attachment incl. soil retention plate and carrying roller for the conventional soil cultivation like stubble field and grass land cultivation
    • Up to four loosening tines can be used for deep loosening of the soil to achieve an optimum rootable horizon and better water absorption.
  • GR 300 for combined mounting with a potato planter:
    • GR 300 combined with a potato planter for a more efficient use of the working time and reduced drivings over the field with several working steps in a single pass across the field.
    • Up to four loosening tines can be used for deep loosening of the soil to achieve an optimum rootable horizon and better water absorption.
