THE MACHINE MATTERSOur Equipment & Capabilities

The Carrier: Caterpillar 275 High-Flow Compact Track Loader

The Cat 275 is Caterpillar's next-generation large-frame compact track loader: a turbocharged Cat C3.6TA engine producing about 111 horsepower, with high-flow auxiliary hydraulics feeding the mulching head. That flow is the number that actually matters in mulching. The head runs on hydraulics, so hydraulic power determines how fast the drum recovers and keeps cutting when it is buried in dense cedar or oak. Standard-flow machines nibble. This one keeps the rotor at speed and keeps moving.

It is fully tracked, which means low ground pressure: it works wet ground, pasture, and lawns without rutting them the way a wheeled machine does, and it travels well on the rough rural ground that makes up most of our work.

The Head: Direct-Drive Mastodon Forestry Mulcher

The head is a Mastodon dedicated forestry mulcher. Two things set it apart from the attachments most operators rent. First, it is direct drive: hydraulic power goes straight to the rotor with no belts or pulleys to slip, burn, or rob power, so everything the Cat produces ends up in the cut. Second, it runs sharp carbide knives, a tooth design that refuses the usual trade-off, and in Oklahoma that matters more than anywhere.

Built in Oklahoma, Bought in Oklahoma

Mastodon Mulchers is a division of Dougherty Forestry Manufacturing, and the heads are machined, built, and balanced in house in El Reno, Oklahoma, right inside our own service area. We bought Oklahoma on purpose. It keeps our money in Oklahoma manufacturing jobs, and it means factory parts and support are a short drive down Route 66 instead of a freight shipment from out of state. When we clear land around El Reno and Canadian County, the head doing the grinding was built minutes from the property. There was no compromise in it either: Mastodon is top-of-the-line gear that holds its own against any national brand, which is exactly why we run it in front of a Cat 275.

Sharp Carbide Knives: The Edge of a Blade, the Life of Carbide

Most mulcher heads make you pick between two kinds of teeth. Knife-style blades slice fast and leave a fine finish, but they dull the moment they touch dirt or rock, and mulching to ground level means touching dirt all day. Blunt carbide hammers survive the rock but smash and splinter the wood instead of cutting it. Mastodon's tooth design is sharp carbide knives: knife-edge cutting geometry with carbide where the edge meets the wood, plus a feed-control profile on each tooth that keeps the rotor from stalling in dense material.

The result on your land: trees and brush sliced into a fine mulch layer that stays on-site, protects the soil from erosion, suppresses regrowth, and breaks down into Central Oklahoma's red clay instead of leaving burn scars or bare dirt. Cut stems are ground down at grade, so the finished ground is ready to bush-hog or drive across.

Built for Cross Timbers Hardwoods

The Cross Timbers belt of dense post oak and blackjack oak runs right through our service area, from Logan and Payne counties down through the east side of the metro. Blackjack oak is slow-grown, dense wood on rocky ground, and it is where light-duty mulching setups give up. The 111 hp carrier, high-flow hydraulics, direct-drive head, and carbide teeth exist for exactly this: grinding blackjack and post oak up to 12 inches in diameter while leaving the mature trees you want standing untouched.

Beyond Mulching

For excavation and dirt work, building pads, gravel driveways, and demolition, we bring the equipment the job calls for and scope it in the same flat project quote. One crew takes your property from overgrown to build-ready without you coordinating a second contractor.

Equipment Questions We Hear

What machine do you use for forestry mulching?

A Caterpillar 275 compact track loader, about 111 horsepower with high-flow hydraulics, paired with a direct-drive Mastodon forestry mulching head. A dedicated forestry setup, not a rental attachment.

What kind of teeth does the head run?

Sharp carbide knives: knife-edge cutting geometry in carbide. They slice cleanly for a fine mulch finish like a knife head, and they survive red dirt, sandstone, and rock like carbide, with no daily sharpening.

Where is your equipment made?

The Mastodon head is built by Dougherty Forestry Manufacturing in El Reno, Oklahoma, inside our service area. Oklahoma-built on purpose: it supports Oklahoma jobs and keeps factory parts and support a short drive away.

How big a tree can you mulch?

Up to about 12 inches in diameter where it stands, including post oak and blackjack oak. Bigger trees can usually be dropped first and mulched on the ground, priced into the same quote.

Does high flow really matter?

It is the difference between a one-day job and a three-day job. The head runs on the machine's hydraulics, and high flow is what keeps the drum at cutting speed in dense material instead of stalling and recovering.
