The Prime Attachments HD Clam Grapple is built for handling brush, logs, roots, fallen trees, and bulky debris with a skid steer. A 51″ opening gives the single grapple plenty of room for oversized material, while 1/2″ bottom tines with replaceable digging teeth help dig, rake, grab, and carry through land-clearing and cleanup work.
Two hydraulic cylinders operate the full-width grapple for a strong, even hold across the load. Grapple stops make back dragging more practical, and three available widths let you match the attachment to your machine. Prime recommends the HD Clam Grapple for small- to mid-frame skid steers up to 75 HP.
What is the Prime Attachments HD Clam Grapple designed for?
The HD Clam Grapple is designed for handling brush, logs, roots, fallen trees, branches, and bulky debris. It works well for land clearing, storm cleanup, landscaping, farm cleanup, and general property maintenance.
How wide does the HD Clam Grapple open?
Prime lists a 51″ grapple opening, giving you room to grab large logs, brush piles, roots, and other oversized material.
What sizes are available?
The HD Clam Grapple is available in 60″, 68″, and 74″ widths. The best width depends on your machine, its operating capacity, and the type of work you plan to do.
Why would I choose a single grapple instead of a dual grapple?
The HD Clam uses one wide grapple that closes across the attachment as a single unit. It gives you a broad, even hold and is a straightforward choice for brush piles, logs, roots, land clearing, and general cleanup. If you regularly handle loads that are dramatically uneven from one side to the other, Prime’s HD Dual Clam Grapple may be a better fit.
Can I use the HD Clam Grapple for back dragging?
Yes. Prime equips the HD Clam Grapple with grapple stops specifically to make back dragging and cleanup more practical.
Are the digging teeth replaceable?
Yes. The lower tines use replaceable digging teeth, so worn teeth can be serviced without replacing the entire attachment.
Does the HD Clam Grapple require high-flow hydraulics?
Prime does not specify high flow as a requirement for the HD Clam Grapple. Auxiliary hydraulics are required to operate the grapple cylinders. Always verify your machine’s hydraulic connections and specifications before ordering.
What size skid steer should I use?
Prime recommends the HD Clam Grapple for small- to mid-frame skid steers up to 75 HP. Horsepower alone does not determine compatibility, however. Your machine also needs adequate rated operating capacity for the attachment plus the material being carried.
Which width should I choose for my skid steer?
A good starting point is an attachment width that is at least as wide as your machine. You should also consider attachment weight, rated operating capacity, stability, and the type of material you expect to handle before choosing a width.
Note: Compatibility depends on your machine’s rated operating capacity, horsepower, auxiliary hydraulics, quick-attach mounting system, and the weight of the material you plan to carry. Always verify your own machine’s specifications before ordering. A model appearing below does not guarantee compatibility with every year or configuration.
