Short answer: Net wrap tearing, shredding, or leaving holes on the bale surface can be caused by either bad wrap (60% of complaints) or a baler mechanical issue (40%). This diagnostic resolves it in 10 minutes.
Three signs the WRAP is the problem: Tearing on the roll edge before it feeds, shredding mid-bale, or visible holes on the bale surface. Three signs the BALER is the problem: The same failure happens with every wrap brand you try, monitor codes appear during wrap cycles, or the problem only occurs at one specific bale density.
The swap-and-test below resolves which one in a single afternoon.
Why operators blame the wrong thing
When a bale comes out torn or shredded, the instinct is to blame the machine. The baler is bigger, more expensive, and usually the most recent investment. Net wrap is cheap and easy to replace, so it gets overlooked. But the symptoms of bad wrap and bad-baler mechanics are nearly identical: the bale comes out damaged, and it happened during the wrap cycle.
The problem is that your brain doesn’t distinguish between them. A bale with holes in the wrap surface is a bale with holes — whether it tore because the wrap is thin or because the baler’s feed rollers are damaged. This is why producers spend weeks suspecting the baler, calling the dealer, maybe even scheduling service — when the real answer was a single wrap roll.
Here’s the good news: there is one diagnostic that breaks the tie, and it takes 10 minutes.
The 10-minute swap-and-test: the gold-standard diagnostic
This is the method every baler dealer tech uses, and it’s the method you need to use. It works because if the problem goes away when you change wrap brands, you know the wrap was the culprit. If it persists with a different brand, you know the baler is at fault.
What you need: A fresh roll of a different net wrap brand (borrow one from a neighbor, pickup from a dealer, or grab a different brand from your shop if you stock multiple). It must be a roll you’ve never used before, and ideally a brand your baler has never seen this season.
The steps:
- Remove your current wrap roll from the baler. Don’t worry about mid-roll — just pull the leader out and set the roll aside.
- Load the fresh roll of different wrap into the baler and thread it through the feed system — exactly as you would for a normal roll swap.
- Bale 3 to 5 bales with the new wrap. Pay attention to the wrap feed and the bale surface as it comes out.
- If the symptom (tearing, shredding, holes) disappears: It was the wrap. Go back to your original roll and set it aside; order a better wrap.
- If the symptom persists: It’s the baler. Return the borrowed wrap, and move on to the seven baler-side causes of net wrap not cutting or check the model-specific guides for John Deere, New Holland, or Case IH.
This single test eliminates weeks of second-guessing.
When tearing or shred problems show up mid-season, the producers who get answers fastest are the ones who borrow a roll of a different brand from a neighbor and run a half-dozen bales the same afternoon — if the issue follows the wrap, it’s the wrap; if it stays with the baler, no amount of new wrap will fix it.
Three signs the WRAP is the cause
Even before you do the swap-and-test, here are the telltale signs that the wrap itself is the problem:
1. Tearing or fraying on the roll edge before the wrap even feeds
Look at the leading edge of the roll — the edge that enters the duck-bill spreader first. If it’s already torn, frayed, or showing daylight through the strands before the baler ever pulls it, that’s a wrap quality issue. Premium wrap has clean, even edges. Cheap or degraded wrap shreds on the edge because the strands have already begun to separate.
This is the early warning sign. If the edge is torn before wrapping even begins, the middle of the wrap is probably already compromised — the entire roll is suspect.
2. Shredding mid-bale (the wrap fragments as it stretches)
Watch the wrap cycle from outside the baler. Premium wrap should feed as a continuous, intact sheet. If it’s fragmenting into pieces or leaving visible holes as it stretches across the bale, the wrap strand diameter is too thin to handle the tension. This is almost always a premium-wrap-vs.-discount-wrap issue.
Discount wrap achieves its lower price by using thinner strands or reducing the strand count per inch. When the baler applies tension to pull the wrap across a large or dense bale, the thin spots snap.
3. Visible holes or thin spots on the finished bale surface
Inspect the finished bale. Does it have isolated holes or gaps in the wrap mesh, even though the wrap didn’t visibly break during feeding? Those are thin spots in the wrap itself. Premium wrap has consistent strand diameter from edge to edge. Discount wrap has variation — some strands are thicker, some are thinner. The thin ones fail under load.
Run a finger over the wrap on a finished bale. Do you feel thin areas? That’s the evidence right there.
Three signs the BALER is the cause
These indicators point toward a mechanical or electrical problem on the baler, not the wrap:
1. The same failure happens with every wrap brand you’ve tried
This is the single most reliable diagnostic. If you’ve run Brand A, Brand B, and Brand C, and all three exhibit the same tearing or shredding pattern, the wrap is innocent. Your baler has a mechanical problem that defeats any wrap you put into it.
From AgTalk threads on Case IH and New Holland wrap issues, a common pattern emerges: a producer swaps wrap brand, problem disappears. This proves the baler was fine all along. Conversely, a producer who has tried three brands with no improvement proves the opposite.
2. Monitor faults, dull mechanical sounds, or actuator delays during the wrap cycle
Open the rear hood during a baling session. Do you hear grinding, clicking, or binding sounds when the wrap cycle fires? Does the monitor display a fault code (Bale-Trak Plus, AgCommand, etc.)? These are electrical or mechanical failures. The wrap has no control over these. Even premium wrap cannot overcome a failed actuator or a dull knife.
Similarly, if the actuator is slow to fire or seems reluctant to engage, that’s an electrical or mechanical symptom. Premium wrap might tolerate a weak baler better than cheap wrap, but it doesn’t fix a broken machine.
3. Failure correlates with a specific bale density or moisture setting, not the wrap
Does the wrap problem only occur when you bale at maximum density? Or does it only happen when the hay is wet? If the symptom is tied to a machine setting or environmental factor, and the wrap is consistent throughout, the baler is adapting poorly to those conditions.
Premium wrap tolerance improves performance in these edge cases, but it doesn’t eliminate a fundamental mechanical problem. If your baler struggles at density 8 out of 10, swapping wrap may help, but you still have a baler tuning issue.
The pull-and-stretch test you can do on the shop floor
Here’s a producer rule of thumb that works surprisingly well: pull a strip of wrap from your current roll — tear off a piece about 12 inches long. Hold both ends and gently pull it between your hands.
Premium wrap: Stretches smoothly, then yields with even, predictable resistance. When it finally tears, it tears in one clean line.
Cheap wrap: Tears unevenly, sometimes immediately, with inconsistent resistance. The tear is jagged and happens suddenly.
This test won’t make your diagnosis for you, but it’s a quick confidence check. If the wrap feels fragile and tears unevenly in your hand, it’ll be fragile in the baler too.
What ‘premium’ wrap actually means in spec terms
You’ll see marketing language like “premium,” “heavy-duty,” and “farm-grade,” but here’s what to actually look for:
- Published breaking-strength specification. The wrap manufacturer should publish the minimum breaking strength (in pounds-force per inch of width) on a spec sheet or the roll wrapper. If there is no number, that’s a red flag. Wrap with a published spec is built to a standard; wrap without a spec is built to a price.
- Consistent strand diameter and density. When you look at the mesh, all the strands should look the same thickness from one side of the roll to the other. If you see thin spots or variation, the wrap has been compromised either during manufacture or during storage.
- UV stability (months of outdoor storage without degradation). Net wrap exposed to sunlight for months should not become brittle or fade dramatically. Check the manufacturing date on the roll. If it was made more than 18 months ago and has been stored in sunlight or heat, assume degradation has begun.
- Clean cut edges (no selvage or ragged borders). The edges of the roll should be smooth and even. Ragged or frayed edges suggest the wrap has already begun to degrade.
You don’t need to memorize these specs. You need one: ask for the breaking-strength number. If the supplier can’t give you one, buy elsewhere.
When the answer is the baler — and what to do next
If the swap-and-test showed that premium wrap works fine in your baler, then you have a mechanical or electrical issue on the machine. The next step depends on what symptom you observed:
- Wrap won’t cut cleanly: Start with the seven baler-side causes of net wrap not cutting — dull knife, low voltage, actuator failure, etc.
- Baler-model-specific problems: Check the model guides for John Deere wrap issues, New Holland wrap issues, or Case IH wrap issues.
- Wrap feeds unevenly or bunches on one side: Check the spreader rollers (buildup, wear), tailgate hydraulic flow, and monitor settings.
These guides will narrow the diagnosis further. The swap-and-test was the first gate; now you’re moving into baler-specific troubleshooting.
What to do if you’ve narrowed it to the wrap
If the swap-and-test showed that changing wrap brands fixed the problem, you have a wrap quality issue. The economic case is straightforward: you’re losing bales, field time, and reputation. A bale with holes or exposed hay attracts moisture, mold, and weather damage. The real cost isn’t the wrap; it’s the bales you lose.
Upgrade to a wrap with a published breaking-strength spec. Look for consistent quality, clean edges, and a manufacturer willing to stand behind the product. Yes, premium wrap costs more per roll. No, it doesn’t when you factor in the bales you don’t lose.
The takeaway
A single 10-minute diagnostic — swapping to a different wrap brand and baling a few bales — tells you everything you need to know. If the symptom disappears, you have a wrap problem. If it persists, you have a baler problem. No guessing, no dealer calls necessary until you’ve made that test.
Most operators who run this test are surprised at how quickly they get an answer. And they’re even more surprised that the answer is often cheaper than they expected: a wrap roll costs a fraction of what a dealer service visit costs. Once you know which one it is, the fix is straightforward.
