Part Number: HD99-H

The Ground Hog Inc HD99 is a Towable Hydraulic Earthdrill that is designed to be powerful, easy to use and require very little maintenance.

The HD99 is the most powerful Earthdrill in the Ground Hog Inc line. Equipped with a powerful VANGUARD gas engine, the HD99 can easily dig with any Ground Hog auger up to 18 inches in diameter. The use of hydraulics allows the HD99 to have variable auger speed and reverse which is very useful if the auger gets stuck.

The HD99 is designed to take the load off of the operator by being almost perfectly balanced with an 8-inch auger attached, and the right angle design eliminates torque to the operator. There are also 3 handlebar positions that allow for normal drilling, as well as close up drilling next to an obstacle such as a wall or fence. The drilling head also pivots from side to side for drilling on uneven terrain. Large highway rated tires make the HD99 easy to maneuver around the job site and there is a locking mechanism on the digging head that allows the auger to be held up and out of the way for moving the machine around the job without having to disconnect the auger.

The heavy duty powder coated steel construction of the HD99 uses a pivoting engine cradle that protects the engine and lets it stay level for proper oiling and longer life. The low profile and compact design of the frame eliminates the need for telescoping booms and axles and allows the unit to be transported in the bed of a small truck. The HD99 also comes equipped with a tow-bar with a 2" Ball hitch coupler and safety chains for surface street and jobsite transport.

The hydraulic system used on the HD99 is extremely reliable and requires very little maintenance compared to mechanical systems, and the HD99 uses high quality Parker components. Typical maintenance that is usually required is simply to check or change the hydraulic fluid and engine oil and replace the hydraulic filter. The uniquely shaped fluid reservoir holds 3 gallons of fluid while having a large amount of surface area to dissipate heat for higher efficiency. The reservoir has a dipstick for checking the fluid level and the drain plugs for the hydraulic fluid. The drain plug for the engine oil, as well as the hydraulic filter, are easy to access and use without making a mess.

The Ground Hog Inc HD99 is a powerful, well designed earthdrill you can rely on!  The HD99 makes easy work of the hardest post hole digger jobs.

Perfect all-around frother, stand keeps it nice and neat on the counter within easy reach.
Color: Black, Size: Rechargeable
Rechargeable, lightweight, variable speeds and optional whisks all make this the perfect item for your kitchen. You can quickly froth milk for your coffees, whip a small batch of whip cream, and even make mug cakes with the hook attachment. The price is very compatible with the competitors, but the ease of use makes this a top choice. The variable speeds makes it much better to control than the push button ones. When you let go of the pressure switch it turns off, no need for a dedicated on-off switch. Having the pressure switch on the top makes it extremely easy to use! It fits very comfortably in the hand and with the metal stand, looks quite nice on the counter, ready to use at any time. I highly recommend this InstaWhisk!

Great product from a great company
Color: Black, Size: Rechargeable
This product works very well. There are several other whips to use also. I absolutely love the cream it makes and that is important so I can enjoy my morning coffee. I used this whisk for quite a while then all of a sudden it stopped working. I wrote to the company to explain. A few days later they sent me a beans new whisk. GREAT item and great company to work with.

Great Frother - almost too powerful
Color: Black, Size: Rechargeable
I’ve been using the Tyohur InstaWhisk milk frother for a while now, and overall I really like it—but I wouldn’t quite give it 5 stars, and honestly it’s because it might be a little too powerful for its own good. First, the positives: this frother does an amazing job. The single-button control is super easy to use, and I love that you can adjust the speed just by how much pressure you apply. It feels very intuitive, and you can really dial in the exact texture you want. Whether I’m making a latte or mixing something thicker like a protein drink, it handles everything smoothly. The performance is seriously impressive. On the lower speeds, it creates nice, silky foam, and when you turn it up, it’s incredibly fast—like café-quality foam in seconds. High-speed frothers like this are designed to create rich foam very quickly, and this one definitely delivers on that promise That said, the power is also what knocks it down a star for me. If you’re not careful (especially when using higher speeds), it can splash pretty easily. The product description says it’s designed to prevent mess with stable low-RPM operation, and that’s true if you stay on the lower settings—but once you ramp it up, you really need to keep the whisk fully submerged or start slow, or it can send milk flying out of the container

Great frother and well built
Color: Black, Size: Rechargeable
I don’t usually write reviews, but since I’ve been helped by so many reviews from others, I wanted to share my thoughts on the InstaWhisk Milk Frother. This is a great frother. It really whips cream into a tasty, rich froth. My wife and I have tried cheaper battery-operated frothers in the past, and while they worked fine at first, they didn’t last very long. The InstaWhisk feels well built and works great. Pro tip: The frother may be a little too powerful at normal speed, so you might need to lightly “feather” the power button to keep the liquid from overflowing the cup. Once you get used to it, it works really well.

Great frother/stirrer especially for the price.
Color: Black, Size: Rechargeable
Best one available. Have used cheap ones from the store that work pretty good, but batteries are a pain. This is rechargeable and it has a push button that allows you to start it right away without having to turn it on to start it kind of like a power drill. If you start to press it it goes slow the harder you press the faster it goes. The different attachments are great. We use it for both coffee frothing as well as mixing up electrolyte drinks with water with the included mixing attachment. Crazy powerful and easy to use.
