The VALENTINI MT – MAMMUT Power Harrows stand at the top of large‑scale soil preparation technology, combining exceptional strength, precision engineering and long‑term durability. Designed to operate in the most demanding conditions — compacted soils, stony terrains, extensive fields and long working days — the MAMMUT series delivers consistent, high‑quality results thanks to its reinforced structure, HEAVY DUTY oil‑bath transmission and high‑speed rotor.
With working widths ranging from 5 to 9 meters, these machines are built for maximum productivity. They allow operators to cover large areas in fewer passes, reducing fuel consumption, tractor wear and overall working time. The high‑speed rotor breaks clods efficiently, incorporates organic matter and leaves the soil loose, levelled and perfectly prepared for seeding. A constant working depth of 30 cm ensures deep, uniform preparation — essential for high‑yield crops and demanding agricultural operations.
The MAMMUT series is engineered for durability. Case‑hardened gears, reinforced chassis and HEAVY DUTY circular blade‑holder shafts ensure exceptional resistance to stress and wear, even in rocky environments. For stony soils, an optional stone‑protection kit increases safety and extends the machine’s lifespan. These power harrows are the ideal choice for professional farmers, contractors and large agricultural enterprises seeking maximum performance, reliability and superior field results.
