Whether you are installing deer fence or just fencing around your garden, using metal fence stakes is a sturdy alternative to wooden stakes. You can drive metal fence stakes quickly with a manual post driver rather than a sledgehammer. But before you drive your first stake, it is a good idea to call the utility companies to come out and identify any underground utility lines. This will not only keep you from accidentally cutting into a service line, but also will prevent death or injury from accidentally hitting a power line.
Place wooden stakes at the corners of the area you are fencing. Tie string around one corner stake, then stretch the string to the next corner stake and tie the string around that stake. Repeat this until you have string on all sides between the corner stakes.
Measure 90 cm (3 feet) up from the bottom of each metal fence stake with a tape measure and mark the spot on the stake with a marker. The bottom of the stake is the portion that has the wide plate on each side of the stake. Place the bottom of your first stake next to one of your corner wooden stakes. The plate is the stake anchor.
Slide the open end of the manual post driver over the top of the metal fence stake. A manual driver is a weighted tube that is closed on one end and has handles on two sides.
Ask a friend to grab the stake near the ground while you start driving the stake. Raise the manual post driver up and then slam it down over the stake. The weight on the closed end will drive the stake into the ground. Ask your helper to let go of the stake when it is driven into the ground a few inches.
Continue pounding the stake until it's 90 cm (3 feet) deep. The mark you made earlier at 90 cm (3 feet) will be level with the ground. Repeat this for all corner stakes. Pound in stakes every 1.2 m (4 feet) between the corners alongside the string.
You can buy a manual post driver at a DIY centre.
Always call the utility companies to identify any gas, water or power lines underground before you drive stakes into the ground.
