9GXB-1.5 Heavy-Duty 1.5m Semi-Circular Rotary Mower for 40-100 HP Tractors

1.5m Semi-Circular Rotary Mower (9GXB-1.5) | Heavy-Duty Tractor Implement

Product Overview

The 9GXB-1.5 Semi-Circular Rotary Mower is an essential agricultural implement built for high-performance grass cutting, brush clearing, and orchard maintenance. Equipped with a heavy-duty single-disc system featuring two high-strength alloy steel blades, this machine effortlessly mulches dense vegetation while minimizing vibration transferred to the tractor.

Its signature semi-circular cover design provides enhanced safety by containing debris while allowing operators to maneuver closely around tree rows and obstacles—making it the ideal choice for orchard owners, pasture managers, and farm equipment distributors worldwide.

Key Features & Technical Advantages

1. Specialized Semi-Circular Housing

The rounded shield profile prevents the mower deck from hooking onto tree trunks, fence posts, or irrigation lines. It smoothly channels cut grass and debris downwards, reducing the risk of flying rocks and improving operator safety.

2. Dynamic 2-Blade Disc System

Powered by a 540 RPM PTO drive, the heavy-duty central disc utilizes two heat-treated swinging blades. The centrifugal action allows the blades to swing back when hitting solid objects (like rocks or thick stumps), preventing gearbox damage while maintaining maximum cutting power.

3. Precise Ground-Following Guide Tire

Equipped with a sturdy 400--8 pneumatic rear tire, the unit maintains consistent ground clearance even over uneven field conditions. Operators can quickly adjust the rear wheel assembly to achieve cutting stubble heights between 4 cm and 11 cm.

4. Rugged & Durable Build Quality

Weighing 340 kg, the reinforced steel structure provides optimal downforce for stable operation at higher field speeds. Powder-coated finishing ensures long-lasting resistance against rust, corrosion, and severe weather.
