What kinds of post drivers do farms use?
Hand-held drivers are a steel pipe with handles and a closed end, and you lift and drop the weight yourself. Tractor-mounted drivers hang on a loader or three-point hitch and use gravity or hydraulics. Gas and air powered drivers strike repeatedly from a handheld unit. Each type has its own hazards, so read the manual for the exact model you own or borrow.
The right choice depends on how many posts you set, the soil you have, and what your body can handle. A person with a bad shoulder or back should think twice about a hand driver, since the repeated lifting adds up over a long fence line.
- Hand drivers: pinch points on fingers, strain on shoulders and back
- Tractor-mounted: crush, overhead and rollover hazards
- Powered handheld: noise, vibration and kickback
How do you set up the work area before driving?
Walk the fence line first. Look for rocks, buried lines, tile drains, water lines and anything else under the ground. Call your state's one-call utility locating service before you drive anything into the ground, and treat that call as part of the job, not an extra. Mark your post locations and clear the footing around each one.
Check overhead too. Power lines, tree limbs and barn eaves all matter when a driver or a tall post is swinging upward. Keep bystanders, children and animals well back, and agree on a signal with anyone helping you so nobody reaches for a post at the wrong moment.
- Call the utility locating service before any digging or driving
- Clear rocks, brush and mud from your footing
- Keep a clear zone around the driver and the post
How should you hold and position the post and driver?
Start the post by hand and make sure it is plumb enough that the driver will land square on top. A driver that strikes off center can glance away and swing back at you. Set the post in the start hole or a pilot hole if your soil needs it, then place the driver over the top.
Keep your hands where the manual says, never on the post top once the driver is moving. Use a stable stance with feet apart, and avoid standing on a bucket, tailgate or wobbly stool to reach tall posts. If a post is too tall, use a platform made for the purpose or a different method.
If the post will not go down, do not force it. Stop, pull the driver clear, and check for a rock or an obstruction. Hitting harder on a stuck post is how drivers bounce and people get hurt. Moving the post a few inches is almost always cheaper than an injury.
What personal protective gear helps?
Hearing protection is not optional with powered drivers or with steel striking steel. Add safety glasses or a face shield, since chips of rust, bark and wood can fly. Gloves protect from splinters and pinches, though some manuals warn against loose gloves near moving parts, so follow your model's guidance.
Sturdy boots with good soles and toe protection guard against dropped posts and weights. Long sleeves and pants help with splinters and treated-wood contact. Keep clothes fitted so nothing catches on a moving part.
- Hearing protection
- Eye or face protection
- Steel-toe or sturdy leather boots
- Gloves that fit and suit the model
What goes wrong most often?
Fatigue leads to sloppy aim and slow reflexes. Take breaks, drink water, and stop when your arms start to shake. Hurry is the other cause: skipping the walk-through, leaving a post leaning, or reaching in to adjust it while the driver is still lifted.
Equipment wear matters too. Look at handles, welds, hitch pins, hoses and guards before every session. A cracked weld or loose pin on a heavy driver can fail at the worst moment. If you borrow a driver, ask for the manual and test it with no one near.
What should you do after the job and when should you get help?
Store a hand driver lying down or secured so it cannot fall. Release pressure and disconnect powered units according to the manual. Wipe and inspect the tool, and note any damage so you can repair it before next time.
If you hit your hand, hurt your back, or feel dizzy or numb after a strike, stop working. Do not tough it out. A doctor or your county health office can advise on injuries and on tetanus questions after puncture wounds. In an emergency, call 911.
Key takeaways
- Call the utility locating service before driving posts into new ground.
- Wear hearing, eye and foot protection every time.
- Keep hands off the post and bystanders far from the driver.
- Stop when tired, and inspect welds, pins and hoses first.
