Honda GX270 Engine Performance

At the heart of the BC446 is the Honda GX270, a commercial-grade engine known for reliability, fuel efficiency, and consistent power output.

Engine advantages include:

• Proven durability in construction environments

• Easy starting and smooth throttle response

• Excellent torque for troweling under load

• Long service intervals and easy maintenance

The GX270 ensures the trowel maintains consistent blade speed as concrete transitions from floating to finishing stages.

46-Inch Trowel Diameter and Coverage

The 46-inch working diameter makes the BC446 ideal for medium to large concrete pours. This size strikes a balance between productivity and maneuverability.

Coverage benefits include:

• Faster finishing of large surface areas

• Reduced operator fatigue compared to smaller trowels

• Efficient overlap for consistent surface texture

This diameter is commonly preferred by commercial contractors who need speed without sacrificing control.

Blade Pitch Control and Finishing Precision

One of the most important features of any power trowel is blade pitch control. The BC446 offers smooth, responsive pitch adjustment that allows operators to adapt to changing concrete conditions.

Benefits of precise pitch control:

• Easy transition from floating to finishing

• Improved surface flatness and density

• Reduced risk of surface tearing or burn marks

• Greater control over final finish appearance

This adjustability helps achieve professional-grade results on every pour.
