With a unique combination of strength, control, and flexibility, The hydraulic grapple rake, a versatile new loader/tractor/skid steer attachment, is speeding forest management tasks.
Even when equipment is used to pick up, move and stack trees, logs, brush or other fire hazards, there are drawbacks whenever management tasks are still being done the old fashioned way: with shovel, chainsaw, and backbreaking sweat. From logging and national park conservation to fire prevention, property and habitat protection.
Bucket attachments of the past tend to scoop excess dirt, incapable of holding unwieldy loads, and are largely ineffective for tasks in need of fine control such are raking limbs, or debris. Those who find themselves responsible for managing private and public forestland are now adding a new, versatile attachment - The hydraulic grapple rake - to their skid steers, tractors, and loaders. This new attachment is much more efficient than manual labor, and adapts easier than the bucket. It hydraulically opens, closes, and moves its jaws of spaced metal tines so it can remove trees, logs and brush or surface rake limbs and debris without removing topsoil that is essential in management of lands. No piling up of unnecessary dirt either. This grapple rake can dig out roots and stumps. It can safely pick up, move, and stack logs, trees, or irregular loads up to several thousand pounds. The grapple rake, with it's intertwined teeth, can also grab and place material down to three inches, and reach within inches of desired forest habitat without disturbing it to lift, drag, rake, or haul loads. This attachment can make piles and pick up from the front or lift them from the top, being helpful when loading debris piles onto trailers or preparing piles for burn disposal.
Bob Chapman was faced with the unwelcome task of removing over 300 trees on his 70-acre, Steamboat, Colorado property due to beetle kill. Due to the enormity of the task, he hired a commercial timber company to do the work.
Chapman noted "It looked like a war zone with logs, branches, and stumps everywhere." also adding "I wondered how they were going to clean up the huge mess without destroying the habitat for the living trees and adjoining grassland. I was so impressed with the way a skid steer mounted grapple rake navigated living trees while removing huge loads of debris that I talked the timber company into letting me operate it for a few days."
He used the hydraulic grapple rake manufactured by Colville, Washington-based AnBo Manufacturing, which specializes in high quality designed products for tractors, loaders, and skid steers. While their attachment operates like a bucket in that it can be raised and lowered, and rolled forward and backward, it has a third hydraulic function to open and close its jaws.
Bob Chapman decided to buy a grapple rake for his multi-terrain loader. By doing this he could handle the ongoing beetle kill and fire preventions tasks on his acreage. Anbo built the grapple rake to fit on Chapman's loader. It was a 6-foot grapple rake with 6-inc tine spacing. This was to allow dirt, but not brush or debris to sift through the rake's tines.
In the past, Chapman used a 4WD tractor with bucket attachment to get rid of the debris. This had unsatisfactory results. "Because the bucket lacked finesse, it left holes and skinned spots that removed topsoil and made it difficult for decorative grassland to grow back." Chapman continued "Since the grapple rake just scrapes debris off the top and can back rake with accuracy, the grass grew back beautifully in one season."
While trying to clear a defensible space around a five acre, Nederland, Colorado property for fire mitigation, Chapman tried to remove flammable juniper ground spread and preserve the aspen that was desired. The juniper grew among rocky outcroppings so the task was very difficult.
With this difficult task in front of Chapman he said. "I'd hired a crew to remove the juniper, but it was basically pickax, shovel, sweat and cuss." Chapman continued, "you couldn't put a chainsaw to it because it grew among rocks and dirt. The needles went right through leather gloves. After two weeks of backbreaking labor, when they'd cleaned up less than 1/10 an acre, the finally quit."
"Using the grapple rake, I was able to pull up the juniper by the roots so it wouldn't grow back -- right from its rocky outcroppings," says Chapman. "My loader has a push force of about 6,000 lbs, and several times I stalled it pushing on big rocks, but the grapple rake was fine. It's strong enough to handle whatever you throw at it."
To satisfy the need for strength, AnBo uses a special type of steel that has twice the yield strength (resistance to bending) and a much higher Brinnell hardness rating (resistance to wear) than T1 steel. This makes the grapple rake light enough for mini or compact skid steers or tractors and also adding strength preserves that give more lift and payload capacity than similar products.
Chapman states, "I don't know how I'd have done the job any other way." With the grapple rake, by himself was able to clear a defensible space around his property. He adds, "I ended up taking out 215 cubic yards of slash and debris, and loaded it onto trailers in about 100 hours. It's great at back-raking, grabbing, stacking, piling, whatever you need. Not only did I save over $10,000 in labor, but also lowered my insurance from $23,000 to $4,000 annually.
With thousands of trees toppled when Hurricane Katrina hit on Tom Hauptmann's property about 60 miles from New Orleans, it took him and his wife three days to make it to their mailbox from their driveway. Cutting and moving downed trees. While others were dragging trees with a tractor and chain, Hauptmann used a front-end loader with a 4-way clamshell bucket to accomplish the task. The inefficiency still frustrated him.
Hauptmann explains, "I could pick up logs, but it was always dicey." He continues, "because the clamshell bucket had no teeth or curvature, I could pinch the logs but not really grip them. The load would slip out when it go imbalance, so it was slow going and I had to be careful. When a load slipped, it not only took extra time to pick it up, but also to clean up the debris left behind."
Dissatisfied with the bucket's inability to rake limbs, leaves and debris from the ground without scooping up dirt, thus causing problems with burning debris. Because the dirt mixed with the debris in the piles to be burned would burn slowly, incompletely, or with too much smoke
Hauptmann decided to try the 6-foot, hydraulic AnBo grapple rake with 6-inch tine spacing.
The grapple rake was strong enough to pick up and carry 40-foot sections of tree up to 18-inches in diameter, Hauptmann estimates weighing up to 4,000 lbs. "My limit is blowing out the tires on my front end loader." By picking up the trees before they were cut into pieces made it faster and easier than cutting all of the logs into smaller sections, then dragging or carrying them separately. He adds, "The grapple rake is strong enough to pick up anything your machine is capable of."
Using the grapple rake, Hauptmann can have the control and grip that he needs to more efficiently clean up and manage his property. He can use the grapple rake to pick up trees, logs, limbs, brush and debris, and is even using it to dig up unwanted stumps and roots.
"Unlike bucket jaws that essentially pinch, the grapple rake wraps around a load," explains Hauptmann. "Its teeth and curvature are better for grabbing and grasping. It operates like a hand and gives much better control and holding power. You can grab so much more with the grapple rake."
Hauptmann learned the grapple rakes efficient capacity by inadvertently building a burn pile oftrees and logs under a power line.
Knowing he had to move the pile, Hauptmann says, "With the bucket, such a job would've taken me 20 loads to finish." But, "With the AnBo grapple rake, it took me five loads to move the entire pile. It made a two-hour project into a 20-minute one."
Hauptmann finds the grapple rake is useful in removing "nuisance trees and brush," quickly. "I simply put the teeth down and rip out the roots and all so they don't grow back," This works great on shallow roots. He simply slides the grapple rakes' teeth along the ground until there's a big enough load to carry to the debris pile. "I could never do that with a bucket because things would slip and go every which way." he says.
"I can pick up and replace items in the burn pile, shift ashes, whatever necessary to kep it buring properly." This is how Hauptmann finds the grapple rake's flexibility by placing and shifting objects in the burn pile for a cleaner, less smoky and more complete burn.
Whether for logging, national park conservation, fire prevention or forest management, the grapple rake is making traditionally, tedious clean-up tasks faster, safer, and easier with its unique combination of strength, control, and flexibility. Those responsible for such work are finding that substituting its technology for costly, time-consuming labor is a good investment that continues to pay back, year after year.
