Bale buster converted to bark and chip grinder. Approx 40-50 YPH production. Unit as 1", 2-1/2", and 3" screens.

New Holland 379 (Bale Buster Conversion)

This New Holland 379 has been converted from a bale buster into a bark and chip grinder, producing approximately 40–50 yards per hour. That makes it a low-cost option for operations that need material processing without investing in a large grinder.

Who This Machine Is For

• Landscaping companies — processes bark and mulch for resale or job use
• Small recycling operations — handles light wood waste and organic material
• Farm and agricultural use — runs off PTO without needing a dedicated engine
• Budget-conscious buyers — entry-level grinding solution at a lower price point

What It Grinds

• Bark — processes bark into usable mulch product
• Wood chips — regrinds chips to desired size using screens
• Organic material — handles lighter green waste and similar material
• Mulch material — produces consistent output with proper screen setup

This is not a high-production tub grinder. It is best suited for lighter material and smaller workloads.

Specs in Plain Language

This unit is PTO driven, meaning it does not have its own engine. It requires a tractor with 40–60HP and a 1000 RPM PTO. That keeps operating costs lower but also limits it to smaller-scale applications.

It includes multiple screen sizes (1", 2-1/2", and 3"), which allows operators to control the final product size depending on the job. That flexibility is useful for producing different mulch or chip sizes.

Production is estimated at 40–50 yards per hour, depending on material type and moisture. Output will vary based on how the unit is fed and the tractor powering it.

Because this is a converted bale buster, buyers should understand it is not built for heavy-duty grinding like larger tub grinders. It is best for light material and controlled use.
