Product Description

Serious branches need a serious chipper. The DK2 OPC506 handles trees and brush up to 6.25 inches in diameter — the largest capacity in the DK2 chipper lineup — powered by a 14HP Kohler Command PRO CH440 engine with 22.7 ft/lb of torque and an auto-adjusting cyclonic drum chamber that deteriorates material fast and thoroughly without jamming or slowing down.

The 11.75-inch double-edge reversible cutting blades drive through large diameter branches cleanly and consistently — flip them when one edge wears down and double the cutting life before a replacement is needed. The cyclonic drum chamber design creates a vortex effect that accelerates material breakdown for faster, more efficient chipping on every pass.

The 59-inch expulsion chute with adjustable cast iron rotating deflector gives you precise control over chip direction — cast iron construction means it handles the daily abuse of continuous commercial chipping without cracking or wearing down like plastic alternatives. The large tool-free swing-open chutes with integrated equipment moving handles give you fast drum access for maintenance and easy machine repositioning on the job site. The premium built-in toolbox keeps your tools organized and on the machine — not left somewhere across the property. The key shutoff with lockout safety switch adds an extra layer of security against unauthorized or accidental operation.

The extended 48-inch safety stability axle with D.O.T. approved 17.5-inch tires and drop stand with 2-inch ball coupler makes this machine stable during operation and easy to move between locations — not highway towable, max 25 MPH for off-road and private property use.

EPA Phase III and CARB Phase III certified — compliant in all 50 states including California.

Ideal For: Land clearing contractors, commercial landscapers, serious property owners, and forestry operators who need the largest capacity DK2 chipper for processing 6.25-inch branches and heavy brush with a cyclonic drum system built for demanding daily commercial use.

Q&A

Q: What is the difference between the OPC506, OPC505AE, and OPC524?
A: The OPC506 is the largest capacity chipper in the DK2 lineup — handling branches up to 6.25 inches in diameter with a cyclonic drum chamber and 11.75-inch reversible blades. The OPC505AE handles up to 5.25 inches with a hydraulic feed roller and electric start. The OPC524 handles up to 4 inches with a dual-belt drum transmission. If you regularly deal with the largest branches and need a cyclonic drum system for demanding daily production, the OPC506 is the right choice.

Q: What is a cyclonic drum chamber and why does it matter?
A: The cyclonic drum chamber creates a vortex-effect that accelerates material breakdown inside the drum — processing branches and brush faster and more thoroughly than a standard drum design. The auto-adjusting feature adapts to different material sizes without manual intervention, reducing jams and maintaining consistent performance across varied debris.

Q: What are the reversible cutting blades and how do they save money?
A: Each 11.75-inch blade has two cutting edges. When one edge wears down you flip it over and keep chipping with the fresh edge — effectively doubling the cutting life of each blade before a replacement is needed.

Q: Why is the cast iron deflector better than a standard deflector?
A: Cast iron is significantly more durable than the plastic deflectors found on many chippers in this class — it handles the constant impact of expelled chips during daily commercial operation without cracking, wearing down, or needing replacement.

Q: Can this chipper be towed on public roads?
A: No. The OPC506 is not highway towable — maximum speed is 25 MPH for off-road and private property use only.

Q: Is this chipper available in California?
A: Yes. The OPC506 is EPA Phase III and CARB Phase III certified — fully compliant in all 50 states including California.

Q: What warranty does this chipper come with?
A: The Kohler engine carries a 3-year manufacturer warranty. The DK2 chassis carries a separate 1-year limited warranty.
