Güde GF 420-4.1 Petrol Tiller – 480 mm Working Width, 5.5 HP Power
The Güde GF 420-4.1 tiller is a robust solution for preparing hard, compacted, or clay soil for sowing, incorporating organic materials, or garden maintenance. The 12 low-wear steel blades ensure consistent performance on difficult ground, while the 4-stroke Power-Engine provides reliability and easy starting.
Vegetable grower and home garden owner (200–500 m²): The GF 420-4.1 is the ideal solution for preparing compacted or clay soil for seasonal sowing. The 480 mm working width covers medium-sized areas in a reasonable time, while the 5-position adjustable working depth (175–350 mm) allows the tilling depth to be adapted to the crop type. The 12 blades ensure effective soil crumbling and quick incorporation of compost, mulch, or fertilizer. Its relatively low weight for its size (73.5 kg) and the 3-height adjustable handle provide control and maneuverability in limited spaces.
Small farmer and professional gardener: The GF 420-4.1 is appreciated for its operational versatility and durability during continuous work cycles. The 5.5 HP power penetrates hardened soil without slowing down, while the integrated clutch protects the engine during maneuvers around obstacles. The all-terrain pneumatic wheels with coarse tread ensure traction on uneven and wet ground. The separate forward/reverse gears (1.5 km/h) and the 5-position depth limiter allow precise work on flat surfaces and gentle slopes.
Public administration and green area maintenance: The GF 420-4.1 is a reliable machine for preparing public areas, municipal gardens, and seasonal soil maintenance. Its robust construction, proven engine, and spare parts availability ensure operational continuity. Krollit technical support guarantees scheduled maintenance and fast assistance.

Frequently Asked Questions
What is the difference between the minimum depth of 175 mm and the maximum depth of 350 mm? The 175 mm depth is for surface preparation, such as light tilling and compost incorporation. The 350 mm depth is for deep tilling, compacted soil, drainage, and deep seedbed preparation. The 5 adjustable positions allow the penetration depth to be adapted to the crop and soil type.
How long do the 12 low-wear steel blades last? The blades have an estimated lifespan of 8–12 years with routine maintenance, including cleaning after each use and wear inspection. On very stony ground, wear may increase, reducing lifespan to 4–6 years. Krollit supplies original Güde replacement blade kits at affordable prices.
Can I use the GF 420-4.1 on slopes? Yes, on gentle slopes up to 20°. On steeper slopes over 25°, stability is limited, so use caution and wear safety equipment. The 73.5 kg weight provides traction on damp slopes thanks to the all-terrain pneumatic wheels.
How much fuel does the GF 420-4.1 consume? Average consumption is 2.4 l/h at rated speed on normal soil. The 3.6-litre tank provides approximately 1.5 hours of autonomy between refuelling. On very compacted or clay soil, consumption rises to 2.8–3.0 l/h.
Does the integrated clutch protect the engine? Yes. The slipping clutch disengages the blade disc when it hits obstacles or roots, preventing engine jerks and blade damage. This extends engine durability on difficult ground.
How much maintenance does the GF 420-4.1 require? Moderate maintenance is required: change engine oil every 50 working hours, 0.55 L, 10W40 type; clean the blades after each use to remove soil residues; inspect the air filter every 10 hours and clean it if dirty; check the drive belt every 20 hours; empty the fuel tank if the machine is not used for more than 2 weeks.
What is the optimal 480 mm working width for different areas? On home gardens of 200–300 m², it covers 150–200 m²/hour. On medium-sized areas of 300–600 m², it covers 200–300 m²/hour. On compacted ground, speed drops to 100–150 m²/hour. Adjust the depth according to the crop type to optimize working time.
