Assessing Your Perimeter Fence for Predator Damage

Ground-level inspections often reveal the first signs of predator activity before an actual breach occurs. Look for packed-down grass, hair caught on lower wires, or fresh digging at the base of the posts. Predators like coyotes and stray dogs will systematically test a fence line for weak points, focusing on depressions in the terrain or loose bottom wires.

Check the tension of the wire along the entire perimeter, paying close attention to corners and dips. High-tensile wire must remain taut to prevent predators from squeezing through or under the strands. Any sagging sections indicate failed splices, loose staples, or shifting corner posts that need immediate reinforcement.

Examine wooden posts for rot at the ground line and T-posts for bending caused by wildlife pressure or fallen branches. A single compromised post can cause dozens of yards of fencing to lose its structural integrity, making it easy for predators to push past.

Fencing Pliers – Channellock 85 Fence Tool

Fencing pliers are the ultimate multi-tool for pasture maintenance, acting as a hammer, wire cutter, staple puller, and splicer all in one hand. When walking a long perimeter line, carrying multiple single-purpose tools is exhausting and inefficient. This tool allows for quick, on-the-spot adjustments to loose staples and broken wires without a trip back to the barn.

The Channellock 85 Fence Tool stands out because of its high-carbon C1080 steel construction and its highly functional hammer-and-claw design. The jaw grip is perfectly engineered for pulling stubborn staples out of weathered oak posts, while the clean-cutting edges slice through heavy-gauge wire without dulling. The comfortable grip prevents hand fatigue during long afternoons of pulling and twisting wire.

• Length: 10.25 inches for maximum leverage
• Material: High-carbon steel with rust-resistant coating
• Capabilities: Hammer head, staple starter, staple puller, and dual wire cutters

While it handles standard barbed and smooth wire with ease, it is not designed to cut hardened high-tensile wire, which will nick the cutting edges over time.

This tool is indispensable for any hobby farmer dealing with traditional woven wire or barbed wire fencing. It is not the right choice for farms utilizing purely high-tensile electric systems where specialized crimpers and cutters are required.

Wire Strainer – Hayes Inline Wire Tightener

Over time, temperature fluctuations and animal pressure cause fence wires to stretch and sag, creating gaps that predators can easily exploit. Inline wire strainers allow for permanent tension adjustment without cutting the wire or rebuilding the entire fence section. They keep the perimeter rigid, ensuring that climbing or burrowing predators cannot force their way through.

The Hayes Inline Wire Tightener is a rugged, cast-aluminum strainer that handles high-tensile wire with ease. Its spring-loaded locking clip ensures the wire remains at the set tension even under heavy snow loads or impact. The compact design fits neatly into the fence line without adding unnecessary weight or snag points.

• Compatibility: Works with 12 to 16-gauge high-tensile wire
• Installation: Requires a tightening handle or crescent wrench to operate
• Durability: Rust-resistant aluminum body with a galvanized steel pin

Using these strainers requires leaving a small amount of slack during installation so the tightener can be threaded onto the wire properly.

This is a must-have for homesteaders managing multi-strand high-tensile electric or non-electric perimeter fences. It is not suitable for lightweight poly-wire or temporary rotational grazing lines.

Post Hole Digger – Seymour S500 Hercules Digger

A fence is only as strong as its posts, and corner braces require deep, stable holes to withstand the immense tension of a predator-proof perimeter. When a post rots or snaps, digging a clean, deep hole quickly is essential to restoring structural integrity. Hand digging allows for precise placement, especially in tight spaces or near existing fence lines where machinery cannot reach.

The Seymour S500 Hercules Digger features heavy-duty steel blades and ultra-durable fiberglass handles that will not splinter or bend under pressure. The scissor-action design maximizes leverage, allowing the operator to pull clean, compacted dirt out of the hole without losing grip. It cuts through tough clay and root-filled soil much cleaner than lightweight hardware store alternatives.

• Handle Length: 48-inch high-strength fiberglass
• Blade Material: 10-gauge steel blades
• Point Spread: 6.25 inches for standard post diameters

Digging in rocky or extremely dry soil requires patience, and using a digging bar alongside this tool is often necessary to loosen rocks.

This tool is perfect for the part-time farmer who needs to replace occasional rotted posts or install secure corner H-braces. It is not ideal for installing hundreds of feet of new fencing from scratch, where a tractor-mounted auger would be more practical.

Wire Crimper – Gripple Torq Tensioning Tool

Splicing broken fence wire by hand twisting creates weak joints that slip under tension or snap when a predator tries to push through. Wire crimpers use metal sleeves to fuse wire ends together, restoring the fence’s original breaking strength. A secure crimp ensures the electrical current flows uninterrupted on hot wires while maintaining physical tension.

The Gripple Torq Tensioning Tool is the gold standard for tensioning and splicing wire using the proprietary Gripple system. It features a built-in gauge that measures the exact tension applied to the wire, preventing over-tightening and snapping. The gear-driven leverage system allows users of any physical strength to apply up to 880 pounds of force with minimal effort.

• Tension Range: Measures from 100 lbs to 880 lbs
• Compatibility: Designed specifically for Gripple wire joiners
• Weight: Lightweight, durable construction for easy field transport

This tool requires the ongoing purchase of compatible Gripple sleeves, which are more expensive than traditional zinc crimp sleeves but offer unmatched speed and reliability.

This is the ideal tool for farmers with extensive high-tensile or woven wire perimeter fencing who value speed and precision. It is not necessary for small, low-tension backyard setups using T-posts and simple wire clips.

T-Post Driver – SpeeCo Heavy Duty Post Driver

T-posts form the backbone of most predator-proof perimeter fences due to their affordability and ease of installation. Driving these steel posts deep into the ground by hand with a sledgehammer is dangerous and highly inefficient. A dedicated post driver uses weight and gravity to drive posts straight, fast, and safely without damaging the post tops.

The SpeeCo Heavy Duty Post Driver features a weighted head and ergonomic, thick-walled handles that reduce vibration and hand strain. Its solid steel construction ensures it will not split or deform even after driving hundreds of posts into hard soil. The interior diameter is perfectly sized to prevent the driver from slipping off the post during use.

• Weight: 18 pounds for optimal driving force
• Handles: Closed-loop design for a secure, comfortable grip
• Finish: Powder-coated to resist rust and corrosion in wet weather

The sheer weight of this tool can cause shoulder fatigue over long periods, so taking frequent breaks is key to maintaining proper form and safety.

This driver is a staple for any hobby farmer installing or repairing T-post fences in standard soils. It is not suitable for rocky, ledge-filled ground where a power driver or auger is required to break through the stone.

Wire Cutter – Felco C12 Two-Handed Wire Cutter

High-tensile fencing wire is incredibly tough, designed to withstand immense pressure without stretching or breaking. Standard wire cutters will quickly dull, dent, or shatter when attempting to cut through 12.5-gauge high-tensile steel. A specialized, heavy-duty wire cutter is essential for making clean, burr-free cuts that fit easily into crimps and strainers.

The Felco C12 Two-Handed Wire Cutter is legendary for its triangular cutting action, which cleanly shears steel wire without crushing it. This unique cutting mechanism prevents the wire ends from fraying, making threading into crimps incredibly smooth. The forged aluminum handles are lightweight yet virtually indestructible, providing excellent leverage with minimal physical effort.

• Cutting Capacity: Cuts steel wire up to 12 mm (0.47 inches) in diameter
• Blades: Hardened steel blades that can be sharpened or replaced
• Length: 19 inches for maximum leverage

This is a premium, high-cost tool that must be kept clean and lightly oiled to prevent rust and maintain its smooth cutting action.

This tool is perfect for the serious hobby farmer who maintains high-tensile wire systems and demands clean, effortless cuts. It is overkill for those working exclusively with soft utility wire or lightweight poultry netting.

Chain Strainer – Dutton-Lainson 400 Stretcher

When splicing long sections of broken woven wire or high-tensile fence, pulling the wire tight enough by hand to splice it is impossible. A chain strainer grips the wire securely and uses mechanical leverage to pull the two broken ends together. This allows the farmer to work with both hands free to apply crimps or twists, ensuring a tight, predator-resistant repair.

The Dutton-Lainson 400 Stretcher features a simple, incredibly reliable design with a high-strength walking beam and a heavy-duty chain. The non-slip wire grips hold onto smooth or barbed wire without slipping or causing damage to the wire’s galvanized coating. Its rugged, all-steel construction means it can survive being tossed in the back of a utility vehicle and used in muddy fields.

• Chain Length: 20-inch high-tensile chain
• Grip Style: Spring-loaded, non-slip clamps
• Operation: Manual lever action

The walking beam mechanism has a slight learning curve, and users must ensure the grips are fully engaged before applying tension to prevent sudden releases.

This is an essential tool for anyone repairing high-tensile smooth wire or traditional barbed wire perimeter fences. It is not designed for stretching wide rolls of woven field fence, which require a specialized pull bar.

Fence Tester – Gallagher Fault Finder Voltmeter

Electric fencing is highly effective at deterring predators, but a single blade of tall grass, a fallen branch, or a broken insulator can short out the system. Without a reliable tester, finding the source of a voltage drop along a half-mile perimeter is like finding a needle in a haystack. A directional fence tester saves hours of walking by pointing directly toward the short circuit.

The Gallagher Fault Finder Voltmeter is a dual-function tool that measures voltage and current flow simultaneously. Its digital display shows the exact direction of the fault, allowing the farmer to trace the short step-by-step. The cordless design means there are no messy ground probes to stick into the dirt, making testing fast and clean.

• Measurement Range: Up to 13 kV
• Power Source: Standard 9V battery (included)
• Display: Large, easy-to-read LCD screen

The device must be held flat against the wire to get an accurate reading, and heavy rain can occasionally interfere with the directional arrows.

This is an absolute necessity for anyone utilizing electric perimeter fencing to protect livestock from predators. It is useless for non-electric physical barriers like standard woven wire or wooden post-and-rail fences.

Best Practices for Reinforcing Weak Fence Joints

Weak joints are the most common failure points where coyotes and other clever predators breach a perimeter. Hand-twisted splices tend to unravel under tension or when subjected to animal impact, creating a gap. To prevent this, always use high-quality compression sleeves or specialized wire joiners rather than relying on simple hand wraps.

When working with woven wire, ensure that the vertical stay wires are properly aligned and secured at the splice point. A weak joint in a woven fence allows predators to push the vertical wires apart and squeeze through. Adding a line of barbed wire or a hot electric wire at the very bottom of the fence line adds an extra layer of defense against digging.

Corner posts bear the brunt of the tension on any fence line, making them prone to shifting over time. Reinforce these critical joints with a proper H-brace assembly, utilizing heavy-duty brace pins and a diagonal tension wire. A sagging corner post will slacken the entire fence line, inviting predators to test the boundaries.

Safety Measures When Working with High-Tensile Wire

High-tensile wire is stored under immense physical tension and behaves like a giant steel spring when cut or released. A runaway wire end can whip back with enough force to cause severe lacerations or permanent eye injuries. Always wear heavy leather work gloves and impact-resistant safety glasses when handling, cutting, or tensioning this wire.

Never stand directly in line with a wire that is being tensioned or stretched with a chain strainer. If a clamp slips or the wire snaps, the recoil path is unpredictable and highly dangerous. Position yourself to the side of the wire line, and keep bystanders and pets well away from the work area.

When unrolling a new coil of high-tensile wire, use a spinning jenny to control the release of the wire. Attempting to uncoil it by hand without a spinning jenny will almost always result in an unmanageable, tangled bird’s nest of wire that is both useless and dangerous to untangle.

Creating a Routine Fence Inspection Schedule

A predator-proof fence is only effective if it is completely intact, which requires consistent, proactive monitoring. Establish a weekly routine to walk or ride the perimeter, looking closely for signs of digging, broken insulators, or fallen limbs. These regular checks allow you to catch minor issues before they turn into costly predator breaches.

Increase the frequency of inspections during seasonal transitions, particularly after heavy winter snowstorms or high-wind spring events. Falling branches can easily snap top wires, while shifting snowdrifts can bury fences, allowing predators to walk right over the barrier. Early autumn is also a critical time, as young predators disperse and actively seek out new food sources.

Keep a dedicated fence repair kit packed and ready in your utility vehicle or barn entrance. This kit should include your fencing pliers, spare crimps, a wire cutter, and a roll of patch wire. Having these items organized and accessible ensures that when you do spot a breach during an inspection, you can fix it immediately rather than putting it off.

Maintaining a secure perimeter fence is an ongoing commitment that directly impacts the safety and well-being of your livestock. By equipping yourself with these specialized, high-quality tools, you turn a frustrating and difficult chore into a manageable, routine task. With a solid maintenance schedule and the right gear in hand, you can rest easy knowing your pasture is truly secure against predators.
