• CAT 315 Forestry Mower Head

Auxiliary Engine Power

John Brown & Sons and Brown Brontosaurus Manufacturing is a full line custom manufacturing shop. There are many reasons to own a smaller sized carrier; Ease of transportation, ability to maneuver in tight spaces, etc. But to put the same power to your mulching head those of us with CAT 312 / John Deere 120’s and similar sized machines, need to add a “power pack” to have the same hydraulic flow as a 300 sized model excavator.

We can outfit your carrier with your choice of either a 200 HP C6.6 CAT engine, or similar John Deere 6 cylinder engine for your machine. Custom piping on the boom and controls in the cab create what is called a Closed Loop hydraulic system. This frees up your carrier to do what it does best and full power and separate hydraulic system to run your mower head, stump grinder, or other attachment.

Please contact us in regards to our current pricing and availability on outfitting your carrier.

The optional auxiliary engines are not needed, but for those that make forestry and land clearing their business, the auxiliary engines drastically speed up your production time and the size material you can clear, paying for themselves in very short order.
