6 Best Ropes For Baling Hay Old Farmers Swear By

There’s no feeling quite like watching the baler kick out perfect, tight bales on a dry summer afternoon. But that satisfaction vanishes the moment you see a busted bale in the field or a sagging, spoiled one in the winter. Choosing the right twine, wrap, or wire isn’t just a minor detail; it’s the difference between a barn full of quality feed and a pile of wasted effort.

Tytan International Sisal: The Biodegradable Classic

Sisal twine is the original, and for good reason. Made from the agave plant, it’s a natural fiber that breaks down over time. If you’re feeding your own livestock, this is a huge advantage. You don’t have to worry about a small piece of twine getting ingested and causing a blockage, which is a real risk with plastic.

The best use for sisal is on small square bales that will be stored inside a dry barn. It has enough strength for a standard 50-pound bale and its rough texture grips well, helping the knots hold tight in older, well-worn balers. When the hay is gone, you can toss the twine right onto the compost pile without a second thought.

Of course, its biodegradable nature is also its biggest weakness. If you leave sisal-tied bales outside, moisture and sunlight will cause the twine to rot and break within a season. It’s also a favorite nesting material for mice and rats, so expect some chewed-through strings if you have a rodent problem in the haymow.

CWC Polypropylene Twine for Modern Round Balers

Polypropylene, or "poly" twine, is the modern workhorse for baling. It’s incredibly strong for its size, won’t rot when exposed to the elements, and is generally cheaper than natural fiber. This makes it the go-to choice for large round bales that put immense pressure on the binding.

This twine is specifically designed to resist UV degradation, so bales can be stored outside for months without the twine snapping. Its smooth, consistent texture also runs well through the complex mechanisms of modern balers, leading to fewer breaks and less downtime. For anyone selling hay or storing it in long rows in the field, poly is the practical choice.

The tradeoff is obvious: it’s plastic. It will last forever in the environment, so you must be diligent about cutting it off every bale and disposing of it properly. A stray piece of poly twine can get wrapped around a tractor axle or, worse, tangled up in a manure spreader, creating a dangerous and time-consuming mess.

BridonMAX Sisal Twine for Small Square Bales

Not all sisal is created equal. BridonMAX is a premium-grade twine known for its exceptional consistency and strength. While generic sisal can have thick and thin spots that cause knotter issues, BridonMAX is engineered to be uniform from the beginning of the box to the end.

This consistency is a lifesaver for anyone running an older, finicky square baler. Those old knotters were designed with a certain tolerance, and a high-quality twine can make the difference between a full day of baling and a full day of cursing. Paying a little extra for premium twine often saves you hours of frustration.

Think of it as an investment in your time. If you only have a few weekends to make all your hay, you can’t afford to stop every ten bales to re-thread a broken knot. For small operations where every minute counts, the reliability of a twine like BridonMAX is easily worth the higher price per bale.

TamaNet+ Edge to Edge Net Wrap for Weatherproofing

Net wrap is a significant step up from twine for round balers. Instead of just a few strands holding the bale together, net wrap encases the entire cylindrical surface. TamaNet+ is known for its "Edge to Edge" technology, which ensures the wrap covers the corners of the bale, preventing hay from fraying and providing superior protection.

The primary benefit here is weatherproofing. A tightly wrapped bale sheds water like a duck’s back, drastically reducing spoilage for bales stored outdoors. This preserves the nutritional quality of the hay, meaning you feed more of what you bale. It also makes for a tighter, denser bale that is easier to transport and handle with a tractor.

However, net wrap isn’t for everyone. It requires a baler specifically equipped for it, which can be a significant investment. The wrap itself is more expensive than twine, and it can be a real chore to remove in the winter when it freezes solid to the bale. Disposal is also a consideration, as you’re left with a large, tangled sheet of plastic mesh after feeding each bale.

Bekaert Class 1 Galvanized Baler Wire Durability

Before plastic twine dominated, baler wire was the standard for making the tightest, most durable bales. Bekaert is a name that has been trusted for generations, and their Class 1 galvanized wire is built for maximum strength and rust resistance. This is the stuff you use when a bale absolutely cannot come apart.

Wire is most often found on older square balers or large, high-density balers making bales for commercial transport. Its incredible tensile strength allows for much denser, heavier bales than twine can handle. Once a bale is tied with wire, it stays that way. You can handle them roughly and stack them high without worrying about breakage.

The downsides of wire are significant, which is why it’s less common on hobby farms today. A loose piece of wire is a serious hazard. It can puncture tractor tires, get ingested by livestock causing "hardware disease," or get wrapped in equipment. You must be meticulous about finding and removing every single piece of wire from the field and the feeding area.

New Holland Precision Poly Twine for Consistency

Just as BridonMAX is a premium sisal, New Holland’s Precision Poly is a top-tier polypropylene twine. It’s manufactured to exacting standards for diameter, strength, and footage per roll. This isn’t your generic hardware store poly twine.

The value of this precision is reliability, especially in newer, faster balers. A consistent twine ensures that the baler’s knotters or wrapping mechanism works flawlessly, bale after bale. This maximizes efficiency and produces uniform bales of the same size and density, which is important for stacking and for accurately estimating your winter feed supply.

If your baling window is short and you’re running a baler that’s sensitive to twine quality, this is a smart choice. It eliminates one more variable in the complex process of making hay. You’re paying for the peace of mind that comes from knowing your twine won’t be the cause of a breakdown on the one perfect day you have to bale.

Tytan Sisal vs. CWC Polypropylene: Key Differences

Choosing between sisal and poly twine comes down to your priorities and how you manage your hay. It’s a classic battle between natural tradition and modern performance. Neither is universally better; they just serve different purposes.

The decision framework is straightforward:

• Storage: If your bales will be stored inside a dry barn, sisal is a great option. If they will sit outside, exposed to rain and sun, you need the weather resistance of poly.
• Use: For feeding your own livestock, especially horses or goats, sisal’s biodegradability provides a margin of safety. If you’re selling hay or it will be handled by others, the strength and durability of poly are more practical.
• Equipment: An old square baler might "prefer" the grip and feel of sisal. A modern round baler is engineered for the smooth, fast feed of poly.

Think about your whole system. A farmer with a 1960s New Holland baler making squares for a small flock of sheep in the barn has a clear answer: sisal. Someone making 1,000-pound round bales to store at the edge of the field for six months needs poly. It’s about matching the tool to the job.

TamaNet+ Net Wrap vs. Bekaert Wire: When to Use

This comparison is less about a direct tradeoff and more about two specialized solutions for very different problems. You’re choosing between protecting the quality of the forage versus ensuring the structural integrity of the bale under extreme stress. Both are about preservation, but in different ways.

Use net wrap when your primary goal is to protect high-value forage, like second-cut alfalfa, from the elements. The wrap creates a thatch that sheds water, minimizing mold and nutrient loss in round bales stored outside. It’s a modern solution for maximizing feed quality when you don’t have enough barn space.

Baler wire, on the other hand, is for when containment is paramount. Think of dense, heavy bales of straw that will be shipped long distances, or low-quality grass hay baled at high moisture for silage. In these cases, the bale is under immense internal pressure, and only the brute strength of wire can reliably hold it together. For most hobby farmers, the safety risks of wire make net wrap the far more practical choice for preserving round bales.

Ultimately, the twine, wrap, or wire you choose is a critical link in your hay-making chain. The best option is the one that fits your baler, your storage methods, and your end-use for the hay. Don’t just buy what’s cheapest; buy what’s right for your farm, and you’ll thank yourself when you’re feeding tight, dry bales in the dead of winter.

Frequently Asked Questions (FAQs)

What is sisal rope for baling hay?

Sisal rope for baling hay is a natural fiber cord made from the Agave sisalana plant, traditionally used to bind square and round bales. Most old-school farmers prefer sisal because it is completely biodegradable and treated with natural oils to deter rodents and resist rot. A standard 9,000-foot or 10,000-foot spool typically provides a tensile knot strength between 110 and 130 pounds, which securely holds small square bales weighing 40 to 60 pounds.

What does knot strength rating mean on baler twine?

Baler twine knot strength indicates the exact amount of pulling tension a tied knot can endure before breaking under pressure. A spool rated at 130-pound knot strength withstands up to 130 pounds of sudden force created as compressed forage expands inside the bale chamber. Straight tensile strength is often double this number, but knot strength is the vital measurement because rope always fails first at the knot. Small square bales generally require 110- to 170-pound knot strength, while heavy commercial bales need 350 to 500 pounds.

How do I thread rope for baling hay into a square baler?

Threading rope into a square baler requires feeding the twine through the twine box guides, tension plates, and the needle eye before securing it. Begin by turning off the tractor and engaging safety locks. Pull the inner lead from each twine ball, route it through the ceramic eyelets, and pass it under the spring-loaded tension plates adjusted to roughly 10 pounds of drag. Finally, thread the twine through the needles at the bottom of the chamber and tie it to the baler frame.

How long does natural sisal baling twine last when stored outside on the ground?

Natural sisal baling twine typically degrades and breaks down within two to six months when left directly exposed to damp ground and outdoor weather. Moisture wicked from wet soil activates soil bacteria that eat cellulose fibers, causing untreated organic ropes to rot rapidly. Sunlight and heavy rain accelerate this decay, leading to snapped strings when moving bales with a hay hook. To preserve sisal integrity through winter, elevate bales on wooden pallets and seal them beneath a UV-treated poly tarp.

Is sisal or polypropylene rope better for baling square hay bales?

Choosing between sisal and polypropylene rope depends on storage, with polypropylene excelling outdoors and sisal offering natural biodegradability around grazing cattle. Polypropylene synthetic twine resists rot, mildew, and ultraviolet rays, holding tight for over two years in outside storage. Sisal rope degrades naturally in soil and breaks down in a cow’s rumen, but it absorbs moisture and can be gnawed on by mice during winter. Synthetic twine also costs about twenty to thirty percent less per foot than sisal.

How much baling twine is needed for 100 square bales of hay?

One hundred standard two-string square bales require approximately 2,600 to 3,000 feet of baling twine to bind securely. Each 36-inch bale uses about 13 to 15 feet of rope per strand, accounting for the length, knot tail, and chamber tension slack. A single 9,000-foot spool of baler twine will easily tie 300 to 340 square bales under normal operating conditions. Purchasing a standard two-ball carton provides 18,000 feet, which covers roughly 600 to 650 typical bales.

Why does baling rope keep snapping in the knotter during baling?

Baling rope repeatedly snaps in the knotter because twine disc tension is set too tight or the knotter billhook has developed sharp burrs. Dull twine knives also contribute to breaking by stretching and fraying the fibers instead of slicing cleanly during the cycle. Check your baler manual and loosen the twine holder spring bolt by a quarter turn to reduce mechanical stress. Inspect the billhook surface with your finger; smooth out any rust or grooves using fine 400-grit emery cloth.

Is it safe to feed livestock hay baled with natural sisal rope without removing it?

Feeding livestock hay without removing natural sisal rope is relatively common among ranchers, but completely cutting and removing all twine remains the safest practice. Cattle can digest small quantities of untreated organic sisal fiber without health complications, unlike synthetic polypropylene, which causes fatal intestinal impaction. However, uncut twine loops can entangle hooves, trap young calves, or clump inside the rumen if large bundles are eaten at once. Always slice both strings and discard them in a waste barrel prior to feeding.
