Excavator Mulchers

11 Products
View as

An excavator-mounted mulcher is a different animal from a skid steer-mounted mulcher. The boom delivers reach the loader can't match, the cab gives the operator an angle of attack on standing trees that's impossible from a track loader, and the thumb circuit hydraulics on most modern excavators handle mulcher flow without modification. The trade-off is weight: an oversized head will throw a mini excavator off balance on slopes, stress pins and bushings, and shorten the life of the boom.

Heads in this collection are matched to compact excavators in the 8,000 to 16,000 pound class, mid-size machines in the 16,000 to 28,000 pound range, and full-size excavators above that. Drum, disc, and fixed-tooth designs across the lineup, with hydraulic flow ratings published clearly so the head you buy works on the standard thumb circuit instead of demanding a hydraulic upgrade.

Why Choose Excavator Mulchers from Skid Steer Store?

  • Heads matched to specific excavator weight classes, not generic "fits most" claims that overload mini machines.

  • Hydraulic flow and pressure published clearly so the mulcher works on your standard thumb circuit out of the box.

  • Free shipping on orders over $5,000, direct to your yard or job site, with fitment specialists by phone.

  • 30-day satisfaction guarantee and price match on every excavator mulcher we carry.

Best Excavator Mulcher for...

Mini Excavators 8,000 to 16,000 Pounds

The best excavator mulcher for mini excavators in the 8,000 to 16,000 pound class is a fixed-tooth head weighing under 800 pounds with hydraulic flow requirements of 15 to 17 GPM at 3,000 PSI. Cuts material up to 6 inches. Look for heads that run on the standard thumb circuit without modification.

Mid-Size Excavators 16,000 to 28,000 Pounds

The best excavator mulcher for mid-size excavators is a heavier-duty drum or fixed-tooth head with hydraulic flow ratings of 20 to 40 GPM. Cutting widths typically 30 to 50 inches and material capacity into the 8 to 9-inch range. Mongo ProGrade fits this profile across the class.

Full-Size Forestry Operations

The best excavator mulcher for full-size forestry work is a high-flow drum mulcher with reinforced rotor and chain or rubber discharge curtain. Built for 25,000 to 68,000 pound machines, hydraulic flow up to 50 GPM, and continuous-duty land clearing on commercial scale.

Brush and Right-of-Way Maintenance

The best excavator mulcher for brush and right-of-way work is a smaller drum or disc head sized for the carrier, with chain curtain protection to control debris near roads, fence lines, or buildings. Hammer or swinging-tine designs handle vines and saplings cleaner than fixed-tooth in this application.

Frequently Asked Questions

What hydraulic flow does an excavator mulcher need?

Compact excavator mulchers run on 15 to 25 GPM at 3,000 to 4,500 PSI, which most modern mini excavators deliver from the standard thumb or auxiliary circuit. Mid-size excavator mulchers need 20 to 40 GPM. Full-size forestry heads can demand 50 GPM or more. Match the head to your machine's auxiliary flow before ordering.

What weight class of excavator do I need to run a mulcher?

Excavator mulcher heads range from roughly 700 pounds for compact machines up to 2,300 pounds or more for full-size carriers. The head should not exceed the excavator's bucket-class lift capacity at maximum reach. Most manufacturers publish a recommended carrier weight range, typically 8,000 pounds at the low end and 68,000 pounds at the high end.

What is the difference between a drum, disc, and fixed-tooth excavator mulcher?

A drum mulcher uses a rotating cylinder lined with teeth or hammers that processes material with high rotor inertia, ideal for continuous-duty heavy clearing. A disc mulcher uses a horizontal cutting disc with replaceable knives, sized for slicing through standing wood. A fixed-tooth mulcher uses bolted-on carbide or steel teeth for clean cuts in dense material.

Can a mini excavator handle a forestry mulcher?

Yes, with the right head. Mini excavators in the 8,000 to 16,000 pound range can run lightweight forestry mulchers under 800 pounds with hydraulic flow as low as 15 GPM. Pushing beyond that weight or flow rating risks boom damage, pin wear, and underperformance.

What is heavy-duty forestry mulching, and which heads handle it?

Heavy-duty forestry mulching means continuous land clearing of dense undergrowth, saplings, and trees up to 8 to 12 inches across acreage-scale jobs. The heads built for this work use high-flow hydraulics, fixed carbide teeth, reinforced shells, and chain or rubber discharge curtains to control debris.

How fast does an excavator mulcher cut compared to a tree grinder?

An excavator mulcher processes standing material as it cuts, leaving behind ground mulch in a single pass. An excavator tree grinder is purpose-built for stumps and existing felled material. Mulchers are faster on broad-area clearing. Grinders are faster on isolated stumps. Most operators running a clearing job carry both.
