01OUTDOOR POWER EQUIPMENT
Precision striking for the garden edge
The Baumr-AG HP420 sits quietly in the shed until the line of a new fence demands attention. Its compact frame and balanced weight make it feel less like heavy machinery and more like an extension of your own arm, ready to work where space is limited.
This tool drives wooden or metal posts into the earth with consistent force. It suits landscapers, farmers and homeowners who value efficiency over brute strength, offering a clean, fuel-efficient alternative to manual labour.
02ENGINE
Four-stroke power in a small package
At its heart lies a 38cc overhead cam four-stroke petrol engine. This configuration delivers a steady 1.67Nm of torque at up to 5500 RPM, providing the sustained power needed for repetitive driving tasks without the high vibration of two-stroke alternatives. The centrifugal clutch engages smoothly as speed increases, allowing for controlled operation.
04FIT
Three sleeves for varied diameters
Included in the carry case are three piling sleeves ranging from 20mm to 80mm in diameter. These guides ensure that whether you are installing slender star pickets or substantial timber posts, they remain perfectly vertical during installation. The variety accommodates different project scales without requiring additional accessories.
05PORTABILITY
Lightweight design for easy transport
Weighing just 23kg including its packing carton, the HP420 is manageable for solo operators. Its compact dimensions allow it to fit in the back of a utility vehicle or be carried across uneven terrain. The low maintenance nature and efficient fuel consumption mean it can run all day on a small amount of petrol, eliminating the need for generators.
