## Ideal for:
A large-acreage option for cash-crop operations needing aggressive primary or secondary tillage on 33 feet in a single pass. The Rock Flex gang system allows individual gangs to flex over uneven ground and through rocks without transferring impact to the main frame — a meaningful advantage in Ontario's varied field conditions. Suited to operations running 200+ HP tractors looking for efficient residue incorporation and seedbed preparation.
## The Sunflower Advantage:
Sunflower, an AGCO brand, has built a strong reputation in North American tillage for its Rock Flex gang design — a system engineered to protect blades, bearings, and frame in stony fields. The 4434 is a proven workhorse in Ontario's mixed terrain, balancing wide cutting width with field-contour responsiveness. AGCO's dealer network provides ongoing parts and service support across the province.
