Unlike climbers, four wheelers have been slow to develop means of creating their own anchor points. Winching can be inefficient and frustrating because it typically relies on trees, rocks, or other vehicles as anchors. An ideal anchor point would be directly in the path of desired travel, but unless there is a lead vehicle (which could more easily use a pull strap), the path itself is often devoid of anchors. Off-line pulls, complex pulley systems, and buried tires are just a few examples of the unsavory, time consuming, and dangerous consequences that are caused by inadequate anchors. Enter the concept of the Pull-Pal, a self-burrowing anchor anchor that can be located precisely where needed, rather than where landscape features allow.

History

The Pull-Pal anchor, sold to the public since '92, is produced in-house at the Gremillions' Colorado facility, as is their other well-known product, the Premier Power Welder. The Pull-Pal consists of a removable steel spade that mounts to an armature (using a locking lever), which folds for compact storage. In soft soils, only a small divot is required to get the spade's sharpened tip to bite in, though harder ground may require a deeper divot or a person to hold the spade upright. With the tip set, the force of the winch sends the angled spade into the ground. 

Finish quality is excellent, and the Pull-Pal comes in two sizes:

• Model RW 9000, recommended for all vehicles up to 9000 pounds (tested, here). Unit weighs 30 pounds. Size is 45 inches long when folded.
• Model RW 6000, recommended for Samurai-sized vehicles. Unit weighs 24 pounds. Size is 32 inches long when folded.

Testing

Loose Dirt

My friend, Jeff Nelson, and three partners, farm 4,000 acres of the Palouse. Jeff knows soil, so based on my description of the test I wanted to run, he took me to a bowl with slopes of over 25 percent. The field had been tilled to 18 inches deep as part of testing on a new implement.

We parked Project WomBAT at the bottom of the slope, and pulled about 100 feet of winch cable to the top of the slope, where the Pull-Pal was set in place. The loose, freshly tilled dirt meant that dropping the anchor's 40 pound weight sent the spade tip 2-3 inches into the ground, and a firm downward push was enough to keep it upright. We linked a 'D' shackle through the Pull-Pal's attachment hole because the hook was too big to fit, then hooked to the shackle and began taking in cable. The Ramsey sent the Pull-Pal spade steadily into the loose dirt. When the spade's near two foot length was out of view, we released the Trooper's parking brake and took it out of gear. (Note that the Pull-Pal is intended to be used to assist wheels in motion, and is not designed to pull dead loads. We just used the brake to set the anchor.) More winching sent the Pull-Pal progressively further into the ground, but resulted in no movement of the truck. As the top of the anchor dove out of sight, I began to think my farmer friend was right when he questioned the Pull-Pal. The trough that started from the original divot stretched eight feet downhill when the WomBAT began to move. From that point on, the Pull-Pal did not budge, and the Ramsey steadily took in cable until the Trooper sat just downhill from its anchor. Enter the shovel.

A few minutes of digging revealed much about the soil and why the Pull Pal had not initially taken hold. Despite the steep slope, spring rains had left the soil very damp. Its consistency from 6-18" deep was like potting clay: damp and plastic. The Pull-Pal had submarined through this greasy layer, stopping when its tip met the resistance of the damp but untilled layer below 18 inches. Extracting the device took about 5 minutes, though the spade was the only portion that actually needed to be dug out. Cleaning off the sticky soil took a few more minutes, but was relatively easy thanks to the steel's hard, slick zinc coating. The Pull-Pal breaks down easily for storage, the armature smoothly hinging back into its stowed configuration (45 inches in length stowed vs. more than 5 feet when open). 

Using a set of storage covers made from vinyl truck tarp material (see future BYOB article), the entire Pull-Pal fit easily into the back of the Trooper (for continued use, a brush bar mount was fabricated). In response to the Pull Pal's widespread acceptance, Garvin Industries (619-440-7415) has even developed a bracket for mounting the anchor on one of their roof racks.

Loose Rubble

Our results were less positive in this unyielding terrain. The Pull Pal relies upon finding an appropriate amount of resistance. Either too much or too little resistance means the anchor can't do its job. In the quarry's rubble, when set into various sizes of starter holes, the Pull-Pal either failed to find a hold, or began to dig in, only to level out and dig a shallow trough as the tip apparently ran into dense rock that couldn't be penetrated. Repeated tests yielded the same results. In this terrain, either the surface was too hard and could not be penetrated, or it was so loose that the unit was pulled through the upper foot or so of ground. We speculate that a significant hole, maybe 18 inches deep, would have to be dug to reach a point where the anchor could both penetrate for a hold and encounter significant resistance once the spade had set in.

Conclusions

The Pull-Pal clearly can provide a viable anchor where none exists, but it has other benefits which are easier to overlook. This anchor can decrease wear and tear by allowing you to select your choice of anchoring locations. This allows you to winch from the first layer of cable, making the most of your winch's mechanical leverage and increasing the line uptake speed. You will also be able to avoid most angled pulls. Though the Camel Trophy testimonials for the Pull-Pal are impressive, for most of us, reducing the strains on personalities and equipment could be the biggest selling point. 

We tested in a variety of soil types and proved the Pull-Pal's outstanding anchoring effectiveness. Even in very loose soils, this anchor is easily set by one person, creates substantial resistance, and requires relatively little effort to extricate. 

The Pull-Pal harnesses your winch's power and dives down until it meets enough resistance to counter the drag of your vehicle. Even when the Pull-Pal dives deeply, extracting it is not difficult. Not many will encounter soil (not sand) that is looser than we tested. If you do, you can expect the Pull-Pal to dive down until it meets enough resistance to counter the drag of your vehicle.

• Testing in hardpan gravel-clay revealed that the anchor creates sufficient resistance after having only buried a portion of the spade.
• In loose rock with soil filler, we found the Pull Pal dug long furrows without setting, searching in vain for resistance. This is especially problematic if a compacted rock layer lies below the loose rock layer, because the anchor can't always find purchase in the hidden rock layer.

How would a stuck enthusiast fare in similar featureless landscapes without the Pull-Pal? Let's just say that removing, burying, and recovering your spare tire, especially in hardpan, would have been a LOT better work out…if that is why you going four wheeling!
