Choosing the right mulching teeth can make or break your land-clearing job. Discover how Diamond Mowers’ options help maximize productivity, durability, and ROI on any terrain.
A mulcher is ideal for a variety of tasks, including land clearing, site preparation, disaster cleanup, forestry management, and right-of-way maintenance. It effectively clears and processes unwanted trees and brush, which contributes to the overall health and improvement of the property that’s being worked on.
But which mulching teeth are best for your Diamond attachments and applications? These replaceable parts endure constant wear from shredding vegetation and ground engagement, so it’s crucial to choose the teeth that best match your needs and work environment to minimize unnecessary downtime.
Read on to discover the mulching teeth options available from Diamond Mowers.

EDGE™ HARDENED STEEL TEETH
Featuring taller “paddles” that ingest more material for a more complete, cleaner mulch on the first pass, the new Edge™ Hardened Steel Teeth make mulching tasks faster and easier. They can be sharpened directly on the drum or replaced in minutes with basic hand tools, minimizing downtime on the jobsite, while their straightforward design simplifies maintenance.
With extended sharpenable edges (which you can learn to sharpen by watching this video), they deliver an unmatched combination of cutting performance and extended service life. Standard on the Drum Mulcher DC Pro X2, these teeth are also compatible with the same drum mulcher attachments as the Twin Chisel™ Planer Teeth and Four-Point Hardened Steel Teeth.
Applications
Thanks to their ability to efficiently ingest large quantities of material, Edge Hardened Steel Teeth are optimized for high-speed cutting of vegetation and brush in clean, low-impact soils with minimal ground contact. Their sharpenable design makes them an excellent choice for maintaining cutting performance across soft terrain without the need for carbide reinforcement.
TWIN CHISEL™ PLANER TEETH
Twin Chisel™ Planer Teeth are engineered to optimize productivity. These robust teeth offer industry-leading durability and can be sharpened and rotated directly on a depth-control drum, providing time-saving convenience for operators.
Best suited for high-production environments and intermittent ground contact, Twin Chisel Planer Teeth are made of hardened steel for maximum strength and impact resistance. They feature improved cutting geometry and heat treatment to increase durability and reduce fracturing. Twin Chisel Planer Teeth are compatible with the Drum Mulcher DC Pro, Drum Mulcher DC Pro X, Drum Mulcher DC Pro X2, Excavator Drum Mulcher DC Pro X, and Boom Drum Mulcher DC.
Applications
Twin Chisel Planer Teeth are ideal for high-volume mulching in soft-to-moderate and low-abrasion soils where ground contact is intermittent. Their dual-tip design excels in processing small-to-medium diameter trees, woody brush, and grasses while maintaining productivity and cutting efficiency in cleaner conditions.
TWIN MAUL™ CARBIDE TEETH
Designed to withstand abrasion and extreme ground contact, Diamond’s domestically sourced Twin Maul™ Carbide Teeth require no maintenance and offer a useful life three to five times longer than steel. With high impact resistance, these teeth produce a medium mulch and are ideally suited for rocky terrain, fire-prone areas, or operations involving rental equipment fleets.
They come standard on the Drum Mulcher OD Pro X and OD Pro X2 and are compatible with every other drum mulcher in Diamond’s lineup, as well as the Disc Mulcher Pro X and Disc Mulcher BD Pro X.
Applications
Twin Maul Carbide Teeth are built for abrasive, rocky terrain and moderate ground contact jobs involving dense wood, tree stumps, and thick underbrush. Their durability and impact resistance make them ideal for working in extreme environments where maintenance access is limited and long wear life is essential.
FOUR-POINT HARDENED STEEL TEETH
Diamond’s Four-Point Hardened Steel Teeth act like an axe by slicing through material with an aggressive design that lets operators grab and pull in material efficiently for a finer mulch. These teeth must be removed from the drum before sharpening to boost efficiency and productivity and extend their useful life.
Ideal for high-production environments, softer soils, and jobs requiring limited ground engagement, Four-Point Hardened Steel Teeth come standard on every disc mulcher in Diamond’s portfolio. They are also compatible with the same drum mulcher attachments as the Twin Chisel Planer Teeth.
Applications
For a finer mulch and cleaner finish with less risk, Four-Point Hardened Steel Teeth are best used in soft-to-medium soils and lighter ground contact environments where dense brush, fibrous species like bamboo or palm, and small hardwoods need to be cut and processed with precision.
ARMORED MAUL™ CARBIDE TEETH
For the harshest mulching environments, Armored Maul™ Carbide Teeth deliver unmatched durability and cutting force. These heavy-duty teeth are fortified with added material around the tip and body to guard against abrasive wear and impact damage. Their reinforced paddle design increases material ingestion and cutting inertia, making them highly effective in rocky, challenging terrain.
Designed exclusively for the Drum Mulcher OD Pro X and OD Pro X2, Armored Maul Carbide Teeth resist fracturing even during high-impact ground engagement and provide longer service life and greater wear resistance in extreme conditions.
Applications
Armored Maul Carbide Teeth thrive in rocky soils and harsh, high-impact environments where constant ground contact and tough materials such as mature hardwoods, dense root systems, or tree stumps would overwhelm standard teeth. Their reinforced construction helps maintain cutting force and durability in more punishing conditions.
WHICH TOOL IS BEST FOR THE JOB?
TAILOR DRUM MULCHERS FOR MAX PERFORMANCE
Diamond gives operators the flexibility to mix and match certain tooth types, allowing them to fine-tune their drum configuration for specific terrain, vegetation, and jobsite demands while maintaining proper balance. For example, contractors running a depth-control drum mulcher may choose a “thirds” setup with Twin Maul Carbide Teeth on the outer edges for abrasion resistance and hardened steel teeth like the Twin Chisel or Edge options in the center for higher cutting speed.
In less abrasive conditions, alternating Twin Chisel, Edge, and Four-Point teeth can provide a strategic blend of aggressive cutting, ease of sharpening, and quick field replacement. This level of customization helps maximize productivity and reduce operating costs.
Note: Armored Maul Carbide Teeth are not interchangeable with other tooth types and must be installed as a full set on open drum mulchers only.
