Finn B40 Professional Compact Straw Blower – High-Velocity Mulching System with 15 HP Kohler® Command Pro Engine and 360-Degree Discharge Capability

Overview

The Finn B40 Straw Blower is an industrial-grade, high-torque mulching machine engineered for landscaping contractors and erosion control specialists who require a fast, uniform solution for seed protection. Powered by a legendary 15 HP Kohler® Command Pro engine, this unit is designed to shred and blow straw at a rate of up to 4 tons per hour, significantly outperforming manual hay spreading. The defining feature of the B40 is its high-velocity discharge system, which can project a consistent layer of mulch up to 45 feet, making it the ideal tool for highway embankments, large residential lawns, and commercial construction sites.

Efficiency and mobility are at the heart of Finn’s engineering. The machine features a compact, balanced frame that can be easily mounted on a standard truck bed or towed on a specialized trailer, allowing for maximum jobsite flexibility. It utilizes a reinforced flail-chain shredding system to break down tight bales without clogging, ensuring a smooth, steady flow of material. With its 360-degree rotating discharge spout and intuitive operator controls, the Finn B40 is a high-efficiency powerhouse built to turn a labor-intensive manual task into a streamlined, high-production operation.
