Master The Extraction: How To Pull Chain Link Fence Posts With Concrete Footings

Successfully pulling chain link fence posts requires overcoming the skin friction of the soil and the massive weight of the concrete "plug" or footing, which typically weighs between 100 and 300 pounds. The most efficient professional method involves using a high-lift farm jack and a Grade 70 transport chain to create a vertical mechanical advantage, ensuring the post and its concrete base are removed without manual excavation.

Pre-Operation Engineering and Equipment Checklist

Removing chain link fence posts is an exercise in physics rather than brute strength. Most residential fence posts are set 24 to 36 inches deep in concrete footings that have expanded into the surrounding soil, creating a flared base that resists upward movement. Before beginning the extraction, you must assess the soil type—compacted clay provides significantly more resistance than sandy loam—and ensure all underground utilities are marked via a "Call Before You Dig" service (811 in the United States). The goal is to apply purely vertical force; lateral force increases the risk of snapping the galvanized steel post, which complicates the removal process significantly.

Essential Gear and Tool Inventory

• High-Lift Farm Jack (e.g., Hi-Lift Brand): A 48-inch or 60-inch jack is mandatory for providing the 3-ton to 5-ton lifting capacity required to break the suction of the concrete footing.
• Grade 70 Transport Chain: A 5/16-inch or 3/8-inch chain, approximately 5 to 6 feet in length, with a grab hook. Avoid using standard "hardware store" coil chains, as they can stretch or snap under the extreme tension of a hydraulic or mechanical jack.
• Heavy-Duty Wood Blocks: Several 2x6 or 4x4 lumber scraps to serve as a stable base for the jack, preventing it from sinking into soft turf during the lift.
• San Angelo Digging Bar: A 60-inch steel bar for prying around the base and loosening the top few inches of soil.
• Reciprocating Saw with Carbide Blades: Essential for cutting the chain link mesh or removing the top of the post if it is bent or damaged.
• Personal Protective Equipment (PPE): Steel-toed boots are non-negotiable due to the weight of the concrete plugs; impact-resistant gloves and wrap-around eye protection are required for handling tensioned chains.

Project Benchmarks

• Estimated Duration: 15 to 30 minutes per post, depending on soil saturation and footing size.
• Labor Requirements: One person can operate a farm jack, though a second person is recommended for stabilizing the concrete plug once it clears the surface.
• Standard Compliance: ASTM F567 guidelines for fence installation specify that footings should be 10 to 12 inches in diameter; removals must account for this diameter when planning the extraction site.

Engineering the Extraction: Step-by-Step Post and Footing Removal

Step 1: Site Clearing and Hardware Detachment

Before applying vertical force, the post must be isolated from the rest of the fence structure. Use a socket wrench or impact driver to remove the carriage bolts from the rail ends and tension bands. If the nuts are rusted—a common occurrence in galvanized systems—apply a penetrating oil and wait ten minutes, or simply use a reciprocating saw to cut the bolts. Ensure the chain link fabric is pulled back at least three feet from the post and secured with bungee cords to prevent it from snagging during the lift.

Warning: Never attempt to pull a post that is still attached to the top rail or fence fabric. The lateral tension can cause the jack to kick out violently, leading to severe injury or property damage.

Step 2: Soil Saturation and Peripheral Loosening

The primary force holding a fence post in place is the friction between the concrete and the soil. If the ground is dry and compacted, use a garden hose to saturate the area around the base of the post for 20 minutes prior to extraction. Use a San Angelo digging bar to probe the perimeter of the concrete footing, breaking the surface tension. Removing just the top 4 to 6 inches of soil around the concrete plug reduces the initial "breakout force" required by the jack.

Step 3: The Choker Hitch and Jack Positioning

Place your wood blocking immediately adjacent to the concrete footing to create a stable, level platform for the farm jack. Position the jack on the blocks, ensuring the lifting toe is facing the post. Wrap the Grade 70 chain around the base of the post as low as possible. Use a "choker hitch" by looping the chain through itself or using the grab hook, ensuring the chain bites into the galvanized steel.

Pro-Tip: If the post is particularly slick, wrap the chain twice around the post before hooking it. This double-wrap increases the surface area and prevents the chain from sliding up the metal pipe as you crank the jack.

Step 4: Incremental Vertical Lifting

Engage the farm jack and begin the lifting process slowly. As the jack handle is pumped, the chain will tighten and begin to bite into the post. You will hear a distinct "thumping" or "cracking" sound—this is the sound of the concrete footing breaking its vacuum seal with the earth. Continue the lift in 2-inch increments.

If the jack begins to lean or the wooden base sinks, stop immediately, release the tension, and reposition the base. As the concrete plug emerges from the hole, the center of gravity will shift. Be prepared for the post to tilt once the majority of the concrete is above ground level.

Step 5: Managing the Concrete "Plug" and Hole Remediation

Once the concrete footing is fully cleared of the hole, do not attempt to lift it by hand. Slide a wheelbarrow next to the post and tip the post so the concrete lands in the barrow. If the post is being scrapped, you can use a sledgehammer to break the concrete away from the steel, though this is often unnecessary if you are disposing of the materials at a construction debris facility.

Immediately fill the resulting hole. Use a combination of structural fill (crushed stone) and native soil, tamping every 6 inches. Failing to compact the fill will result in a localized depression that collects water, potentially undermining the stability of adjacent fence posts or landscaping.

Comparative Analysis of Extraction Methods and Soil Suitability

The choice of extraction method is often dictated by the number of posts and the specific site conditions. While the farm jack is the universal standard for DIY and small-scale professional work, other methods may be more appropriate for large-scale operations or extremely difficult soil matrices.

Field Complications and Mechanical Remedies

Scenario 1: Post Snaps at the Ground Line

This occurs when the galvanized steel has suffered from oxidation at the soil-to-air interface, or when excessive lateral force is applied.

• Root Cause: Metal fatigue combined with high friction at the footing.
• Actionable Fix: Transition to a "plug puller" approach. Use a masonry bit to drill two holes into the remaining concrete footing. Insert heavy-duty wedge anchors or eye bolts. Attach the chain to these anchors and use the farm jack to pull the concrete plug directly, bypassing the broken steel post entirely.

Scenario 2: The Jack Sinks Without Lifting the Post

In soft or sandy soils, the downward force of the jack exceeds the load-bearing capacity of the ground.

• Root Cause: Insufficient base plate surface area.
• Actionable Fix: Increase the footprint of the jack base. Use a 2-foot by 2-foot piece of 3/4-inch plywood or a "cribbing" stack of 4x4 timbers to distribute the weight across a larger area of soil.

Scenario 3: Concrete Plug is Oversized ("Mushroomed")

Sometimes, installers pour too much concrete, creating a footing that is wider than the hole above it, essentially locking it in place like a deadman anchor.

• Root Cause: Poor initial installation technique.
• Actionable Fix: Use a power auger or a manual post-hole digger to remove the soil around the perimeter of the "mushroom" head. You must widen the exit path to a diameter larger than the widest part of the footing before the vertical lift will be successful.

Frequently Asked Questions

Can I reuse the fence posts after pulling them?

Yes, provided the posts were not bent during the extraction process and the galvanization is still intact. You will need to remove the old concrete footing by striking it with a 10-pound sledgehammer; the vibration usually breaks the bond between the steel and the concrete, allowing the metal to slide out clean.

Is it better to pull the post or cut it off below grade?

Pulling the post is the superior method because leaving concrete footings in the ground creates "ghost" obstructions for future landscaping, fencing, or utility work. However, if the post is located near a gas line or sensitive root system, cutting it 12 inches below grade and covering it with soil may be the safer alternative.

How much does it cost to hire a professional to pull fence posts?

Professional fencing contractors typically charge between $20 and $50 per post for removal, often with a minimum trip fee. If you have more than 10 posts to remove, renting a high-lift jack for approximately $25 per day is significantly more cost-effective.

How do I prevent the farm jack from slipping on the metal post?

The most effective way to prevent slippage is to create a "shelf" for the chain. You can do this by slightly tightening a heavy-duty bolt-on tension band just above where you place the chain. The chain will slide up until it hits the band, which provides a mechanical stop that allows the jack to exert full force.
