Although not rocket science, here is some helpful advice on how to drive your GroundGrabba Pro into the ground.
To use GroundGrabba ground anchors it is best used with a cordless drill.
Sure, you can try and use a lug wrench or socket but GroundGrabbas are made to make life easier and more secure in your staking process.
Sorry, your cheapy supermarket home handyman cordless drill specials probably just won’t cut it.
We suggest a high torque 18v (or higher) drill minimum of 48ft lb (65nm). My first cordless drill had 48ft lbs (65Nm) and it took its toll on the drill. My next drill which I still use today has 125Nm or 92ft lb of torque and handles the task much better.
But for our steel GroundGrabbas, if you want a definite no hassle approach you could do as I have done and get yourself a large cordless impact wrench (rattle gun) which has over a whopping 740ft lb (1,000Nm) of torque!
Please note: Only use impact type drills with our GroundGrabba Pro steel ground anchors.
Then, to adapt to the ¾” (19mm) hex head you will need a socket for your drill.
Please note if you have a 3/8” or ½” drive impact wrench it is best to use a socket made for purpose.
Will GroundGrabbas go through rock?
NO, they will not! If you hit a rock or underground obstruction just do what you’d do if hammering a stake… move it!
If you find the ground too hard it is recommended to drill a pilot hole with one of our 12” (300mm) masonry drills to its full length. Sometimes the ground may be so hard that unless you have a very high torque impact wrench you may not be successful. Also if the ground is extremely hard like concrete, if your impact wrench has the torque you may find the ground will crack around the ground anchor. You will know if the GroundGrabba has enough purchase or not. Often I find that it is in so tight that the steel can make a pinging sound if you tap it with something steel.
Steps to deploy
1/ Make sure that there are no underground dangers such as services not limited to: Electricity, gas, communications, water, sewage/effluent, drainage.
2/ Place the pointed tip of the GroundGrabba against the ground where you need to deploy it.
3/ Place the ¾” (19mm) socket (which is already in the drill ready for use) on top of the GroundGrabba hex head.
4/ Hold the drill steady with a tight grip in BOTH HANDS, one on the handle the other on top of the drill body so you can push down.
5/ Make sure your feet are about 12” (or 300mm) apart and you have a sure footing and that…
6/ The drill handle is just on the inside of your RIGHT leg (if using a longer GroundGrabba you may only be able to achieve this after the GroundGrabba has wound itself down far enough) which helps prevent wrist injury should the drill handle want to twist counter clockwise.
7/ Start your drill slowly (Best on a medium safety torque setting until you are competent with being able to increase it) pressing down on the drill.
8/ Keep the speed slow with downward force until you feel your drill slow down more as the flights bite into the ground and start to draw itself downward.
9/ As the GroundGrabba draws itself down, if you choose you may now reduce the down force.
10/ When the hex head of the GroundGrabba reaches almost ground level you can stop.
NB. If you drill too fast or without enough downward force or both all you may do is bore a hole in the earth and your GroundGrabba will not anchor to the best of its ability.
Steps to Extraction
1/ Remove any loose attachments or tie downs from your GroundGrabba before starting the extraction process.
2/ Place the ¾” (19mm) socket (which is already in the drill ready for use) on top of the GroundGrabba hex head.
3/ Hold the drill steady with a tight grip in BOTH HANDS, one on the handle the other on top of the drill body so you can push down.
4/ Make sure your feet are about 12” (or 300mm) apart and you have a sure footing and that…
5/ The drill handle is just on the inside of your LEFT leg which helps prevent wrist injury should the drill handle want to twist clockwise.
6/ Start your drill slowly, or if experienced it’s ok to use high speed (Best on a medium safety torque setting until you are competent with being able to increase it) pressing down on the drill.
7/ Keep the speed slow (or high speed when experienced) with downward force so as to keep the drill socket connected to the hex head and the GroundGrabba will start rising.
