Spearhead - Model Multicut 420 -Rotary Mower

Featuring a sturdy driveline, three rotors (each with three blades) operate at 80 metres per second. Coupled with our hardworking 100hp (75kW) gearbox, this is a high-performance mower.

Four heavy-duty wheels ensure stability, while inward folding wings reduce the transport width to 2.9 metres. Plus, there’s no need for an on-road towing kit as it’s a linkage mounted machine.

• Ideal for smaller tractors with tight access.
• Fast mowing from nine blades over three rotors.
• Folding wings make transport a doddle.
