Testing the Pull-Pal Winch Anchor
Model RW9000

The Pull-Pal ready for action, and also folded.

As a rock climber, I understand the importance of good anchors. If you climb a route, you can top-rope with a solid anchor point at the cliff's top, lead-climb and find suitable anchor points as you climb, or free solo and be so confident that you do not need a rope or anchors. Rock climbing is like serious four wheeling; dependable anchors often make the difference between making progress or turning around... or walking home to get the cavalry.

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 that can be located precisely where needed, rather than where landscape features allow.



History

In the early '70s, Jan Gremillion's father enjoyed four-wheeling in the sands of Blyth, CA. It was a fateful and frustrating day that inspired the Pull-Pal. Seriously stuck in the sand, with no good anchor, her father spent two hours walking to find help -- and considering ideas for an anchor. He married his four-wheeling needs with his childhood experience with farm plows. The original Pull-Pal resides with Jan and her husband Pat, a reminder of the Pull-Pal's enduring design. The Pull-Pal's design has gone through numerous design refinements spread over a quarter century of testing.

Dig the tip of the spade in and the Pull-Pal does the rest.

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:

Testing

Camel Trophy teams, as well as the team that made the first winter ascent of Mt. Washington, give impressive testimonials for the Pull-Pal. These groups encountered predominantly mud or snow/ice terrain. The test vehicle, unless otherwise noted, is a 4800lb '89 Trooper with a Ramsey REP6000 winch.

Loose Dirt

In the Palouse region of eastern Idaho and western Washington state, wheat is king. The landscape, dominated by agriculture, makes drivers feel as though they are moving through a giant mogul field. The round hills rise a hundred feet high, and span a few hundred yards across. The resulting steep slopes require special hydraulically-suspended combines to harvest the crops. Those same slopes offer a vast testing ground for off-road products.

Jeff Nelson and three partners farm 4,000 acres of the Palouse. My friend 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.

The Pull-Pal digs in and down...

We parked the Trooper 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 Trooper 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.

Digging the Pull-Pal out can be the hardest part of using it!

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).


In loose rubble, the spade would dig in but not always find sufficient resistance.

Loose Rubble

To test the Pull-Pal in rocky ground, we used an abandoned rock quarry. The terrain was composed of igneous rock that ranged in size from small flakes to pumpkins sized chunks, all intermixed with a small amount of dry soil.

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.

Hard, rocky soil provided solid anchoring.

Rocky Hardpan

After disappointment in the quarry's moonscape, we tested the Pull-Pal in rocky hardpan that did not exhibit the extremes found in the quarry. The dry hardpan ground was made up of gravel mixed with heavy clay soils and had been compacted by earthmoving equipment. We made a small divot, about the size of a grapefruit, in a small slope that angled away from the truck. This was more than adequate for the spade to take hold. As the picture shows, complete spade penetration was unnecessary to give sufficient resistance for the Ramsey to overcome the Trooper's 4.55 gears, parking brake, and a large rock wheel block.

Conclusions

The Pull-Pal has been steadily gaining acceptance within off-roading circles as THE anchoring device to carry. Not surprisingly, global military powers have also begun to recognize the device's capabilities, purchasing numerous units for combat extrication.

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, and also allows you 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.

Because terrain with the latter soil profile is rarely encountered outside of a quarry, this test was more relevant for understanding how the Pull-Pal searches for resistance than for actually predicting how it will perform in conditions readers will one day face. Still, it was apparent that given a shovel and some imagination the device could be effectively anchored even in "soil" such as this.

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 more challenging work out... if that is why you going four wheeling!

The makers of the Pull-Pal also produce the Premier Power underhood welding system.
