Gollmer & Hummel Elite Drag Hose vs. Red Dragster

How Do They Stack Up?

Drag hose is a vital component of a liquid manure injection dragline system, hence the application method's name, dragline. Disruptions in the drag hose could cause a manure applicator to fail to meet their operation's demands, their customer's demands, or arguably worse, cause environmental issues. Because hose is so important, manure applicators need to be able to rely on, and be confident in their investment. The quality of a drag hose will play a role in the longevity, durability, and safety of a manure injection dragline set-up. It goes with the saying, 'you get what you pay for.' 

With several brands competing for share in this niche marketplace, it is critical that manure applicators compare and weigh the pro's and con's of each brand offering, in order to make an informed investment decision.

Two popular drag hoses available in the marketplace are Gollmer & Hummel's Elite Drag Hose, and ASOE's Red Dragster. Equipment manufacturer, Bazooka Farmstar, is the North American strategic partner of the Germany-based company, Gollmer & Hummel. Bambauer Equipment, another manufacturer in the manure injection playing field, has paired up with China-based hose manufacturer, ASOE.

Both Bazooka Farmstar and Bambauer Equipment supply 660', 990', and 1,320' single length hoses. Both hose manufacturing brands they represent produce their hose using the "through-the-weave" process, with polyurethane material used on the inner and outer construction of the hose. G&H Elite & Red Dragster drag hoses are comparable from a weave strength and adhesion standpoint as well. 

Now, let's get down to the nitty-gritty and take-a-look at how these two hoses stack up against one another.
(
The specifications outlined below are based off each company's six-inch diameter drag hoses.)

 

WEAVE 

Ultimately, the consistency of the weave is the key to the success and lifetime of a drag hose. When it comes to drag hose manufactured with the through-the-weave process as these hose brands are, the better the weave, the stronger the hose.

How the two brands stack up:

WEIGHT 

The weight of a drag hose is a composition of all the hose inner workings. Those inner workings contribute to the durability and longevity potential of the hose. In other words, the heavier the hose, the heavier-duty the hose.

How the two brands stack up:

Red Dragster: 1.68 lbs./ft.

G&H Elite Drag: 1.88 lbs./ft.

This makes G&H Elite Drag 12% heavier than Red Dragster.

 

WALL THICKNESS 

The wall thickness of a drag hose determines its ability to handle abrasion and withstand various field conditions. The more durable the hose, the more time and money a manure applicator has the potential to save.

How the two brands stack up:

Red Dragster wall thickness: 0.17 in.

G&H Elite Drag wall thickness: 0.20 in.

This makes the wall thickness on G&H Elite Drag 17% thicker than Red Dragster.

 

COVER THICKNESS 

Similar to wall thickness, the cover thickness of a drag hose can make a difference in drag hose longevity, especially when working in less than ideal field conditions. Again, the thicker the cover, the more durable the hose.  

How the two brands stack up:

Red Dragster cover thickness: 0.071 in.

G&H Elite Drag cover thickness: 0.115 in.

This makes the hose cover on G&H drags 61% thicker than the competitor.

 

TENSILE STRENGTH 

Tensile strength helps the hose withstand stretching and pull forces while out in the field. The higher the tensile strength, the more longevity the hose has.

How the two brands stack up:

Red Dragster tensile strength: 60,000 lbs.

G&H Elite Drag tensile strength: 65,000 lbs.

This makes the tensile strength on G&H Elite Drag 8% higher than Red Dragster.

 

WORKING & BURST PRESSURE 

With working and burst pressure, the higher the pressure rate, the more manure that can be pumped through the hose.

How the two brands stack up:

Red Dragster working pressure: 150 PSI | burst pressure: 450 PSI

G&H Elite Drag working pressure: 200 PSI | burst pressure 600 PSI

This makes the working and burst pressures of the G&H Elite Drag 33% higher than Red Dragster.

 

A LITTLE EXTRA FOR THE PEOPLE IN THE BACK 

Red Dragster is made of 100% polyurethane with a high tensile strength and abrasion resistance. Bambauer offers Red Dragster hoses in 4.5", 5", 5.5", 6", 7", and 8" diameters. The hose is constructed without any adhesives or glues. Its smooth cover and adhesion strength helps extend the life of the hose. The lightweight design of the hose allows for easy handling. 

Similarly, G&H Elite Drag Hose is also made of polyurethane. Its design gives it superior abrasion resistance and tensile strength to keep an applicator pumping. The company uses a 3:1 safety factor in effort to increase the life of the hose and decrease the chance of hose damage. Before leaving G&H, each series of hose goes through quality checks from adhesion to burst testing, ensuring a product capable of being with you for the long haul. In addition, drag hose from G&H goes through a normalization process to ensure that the hose doesn't swell, or vary in size from the provided specifications during the manure pumping process.

 

SO, WHICH HOSE IS RIGHT FOR YOU? 

Ultimately, the decision is up to you -- weigh the costs associated, evaluate the specifications and what those specifications could mean for your operation in the long-run. 

In the event you're a visual learner, here's a couple of additional images to help you compare the two hoses further.

THE KEY TO LONGEVITY 

No matter what diameter, length, material type, or brand of hose you choose, there are a few basic practices that hold true across the board, in order to keep your hose in good shape and prolong its longevity.

1. Clean Before Storage

Before rolling up and storing your hose post-pumping season, make sure it is cleaned out thoroughly. This can be dangerous, but is a vital task and should be performed with extreme caution. One way to clean out is by running a foam ball or bullet through the length of the hose. 

2. Wind-Up When Hose is Not Being Used

Whenever you are not using your hose, make sure it is wound up and out of harms way. Hose is susceptible to damage from animals, equipment, weather, and other risks when left out in a field unattended.

3. Keep Hoses Out of the Sun

Even when rolled up on a reel, it is important to make sure that the hose is out of the sun. Store your hose in a shed or building to prevent damage from the sun.

4. Roll up Carefully

When rolling hose onto a reel, be mindful in the way you are winding it up. If couplers or hoses get pinched, permanent damage can be done to both the hose and fittings. Engineered to reduce abrasions, hose saver clamps can be used to reduce the likelihood of tearing when being reeled up.

5. Inspect Your Hoses Before the Season Starts

Before the pumping season starts, lay out all hoses and inspect the ends and body of the hose for any wear or abrasions. Develop a system to help you catalog your hoses based on the condition they are in. With a system in place, knowing the condition of each hose when laying them out in the field will be a quick and easy task.

6. Follow Pressure Guidelines 

Keep the pressure in the hoses under, or at the recommended working pressure determined by the manufacturer. When changing pressure, be sure to change gradually.
