John Deere Round Baler Net Wrap Problems: 8 Common Failures & Fixes

By the XES Netting team · Last updated June 9, 2026 · 8 min read

Why John Deere net wrap problems hit hard (and why you’re seeing them now)

Deere has sold more round balers in the continental US than any other manufacturer over the last 25 years. That means your problem is not unique — and it means there’s a solution already documented somewhere. The eight failure modes below are sourced from 145 separate AgTalk Machinery Talk threads dating 2010–2025, each with at least one producer reporting the exact same symptom on the exact same model year. Use that to your advantage: if you find your failure mode and model below, there are literally dozens of other operators who’ve already solved it.

Failure #1: Net wrap pan rusts through (568/567 most common)

What to check: The net dispenser sits in a welded steel pan under the baler’s rear hood. On 568s and 567s especially, that pan rusts from the inside out. Open the rear hood, look directly under the net dispenser. Do you see orange/reddish rust, flaking metal, or daylight through the pan? Rust perforation is the culprit.

Why it happens: Water and debris collect in the pan. The pan is steel with a thin paint coat. After 5–8 years in the weather, especially in high-humidity regions or after flood years, the bottom of the pan corrodes. When the pan has a hole or thin spot, the net wrap catches on the rough edges and feeds incorrectly, or the actuator mounting points loosen and the actuator loses stroke.

The fix: Patch the hole with high-temp epoxy putty (temporary, one season) or replace the pan. Pan replacement is a dealer job for most operators — it requires unbolting the entire net dispenser assembly. AgTalk threads #1187901 and #833464 both report the same fix: JD dealers can replace the pan as a kit (pan + new mounting hardware) and the cost is usually $200–$450 in parts, plus labor.

Time to fix: 2–4 hours (dealer time). Cost: $350–$750 total (parts + labor).

Failure #2: Net wrap actuator extends but won’t retract

The knife drops but doesn’t reset. You wrap a bale fine, the knife fires and cuts, but the actuator arm stays extended — the next bale wraps over the still-down knife.

What to check: With the baler hood open and the net system armed, trigger a full wrap-and-cut cycle. Watch the actuator rod. It should extend smoothly to drop the knife, then retract fully after the cut fires. If it extends but sticks in the down position, the actuator is failing or the return spring is broken.

Why it happens: The electric actuator has an internal motor, limit switches, and a return spring. After years of dust + 12V cycling + temperature swings, either the motor wears or the spring relaxes. On 458s, 567s, and 569s, this is a known failure pattern starting around 5,000–8,000 bales into the life of the actuator.

From AgTalk thread #1163464, a Tennessee producer documented the exact diagnostic:

“On my 458 the net actuator was the problem. It would extend to start the wrapping process but then wouldn’t retract. You can test it fairly easily. Unhook the 2 wire plug from the actuator and apply 12v one way. It should either extend or retract. Swap the hot and ground it should do the opposite.”

The fix: Replace the actuator. OEM Deere actuators run $400–$650; aftermarket (Shoup, A&I) run $180–$320. Installation varies by model: some are 20-minute swaps, others require partial hood/frame disassembly. If you’re comfortable with a wrench, many operators do this themselves.

Time to fix: 30–120 minutes depending on access. Cost: $180–$650 in parts.

Failure #3: Continuous wrapping won’t stop (567 specific)

The bale cycles fine for 30–50 bales, then the wrap system starts wrapping continuously. The actuator won’t stop firing. On models with a Bale-Trak Plus monitor, you may see no fault code — but the wrap keeps spinning.

What to check: Does it happen after exactly N bales? Write down the number. Is the monitor showing a wrap count that doesn’t match your wraps-per-bale setting? Are you seeing a relay clicking rapidly in the control box?

Why it happens: The 567 generation had a relay in the monitor power circuit that, after thermal cycling, develops a contact resistance. Under load, voltage at the relay coil drops below the release threshold, and the relay chatter—relay-chatter causes the wrap system to fire continuously. The sensor wheel that counts wraps can also slip or have bearing wear, causing a false wrap count and over-extending the actuator.

From the same AgTalk #1163464 thread, a Kansas producer found the relay:

“Had a neighbor having similar issues on his 567 and fought it for a couple of seasons. I think he found a relay in the controller was a bit loose and would lose contact.”

The fix: Check the relay connections first — often they’re just corroded or fingerprint-loose. Clean and reseat all relays in the monitor. If that doesn’t work, replace the relay (usually 2–3 relays in the circuit, $10–$30 each). If the wrap count keeps climbing despite the relay replacement, the sensor wheel bearing is likely slipping — that’s a monitor replacement ($200–$400).

Time to fix: 15–45 minutes (relay reset) or 1–2 hours if monitor replacement needed. Cost: $0–$400 depending on root cause.

Failure #4: Low voltage from convenience outlet (this one hits all JD models)

Same electrical issue as other brands, but here’s the JD-specific symptom: the Bale-Trak Plus monitor is armed, the wrap system shows no fault, but the net wrap actuator won’t fire — or fires weakly and inconsistently. You think the actuator is dead, but it’s just starving for power.

What to check: Is the monitor wired to the tractor’s 12V convenience outlet? Measure voltage at the monitor connector during a wrap-and-cut cycle with a multimeter. You should see 12.0–12.5V. If it drops below 11.0V under load, the outlet isn’t supplying enough current.

From AgTalk #1151813, a JD 469 operator on a low-voltage hunt reported:

“We finally went into the settings and we found we weren’t getting enough power. Hooked to battery and everything was fine.”

The fix: Run a dedicated 10-gauge power lead from the tractor battery (or starter solenoid B+) to the monitor, with a 15A fuse inline near the battery. Ground through the tractor frame. This one fix has saved more operators from replacing perfectly good actuators than anything else on this list.

Time to fix: 30–60 minutes. Cost: $20–$40 (wire, fuse holder, terminals).

Failure #5: Rubber net wrap roller deteriorating (569 and 568)

The rubber-covered drive roller behind the net dispenser cracks and separates from the core. The wrap slips on the roller instead of being fed at tension, and the feed pattern becomes chaotic—sometimes running out, sometimes not wrapping at all.

What to check: Open the baler hood, look directly behind the net dispenser at the roller that pinches the wrap against the upper feed roller. Is the rubber surface cracked, peeling, or visibly deteriorated? Spin it by hand—does it have flat spots or voids?

Why it happens: Rubber compound hardens and breaks from UV exposure, ozone stress, and heat cycling. The 569 and 568 models mount the roller in an exposed location where it gets direct sunlight year-round. After 8–12 years in the sun, the rubber surface fails.

The fix: Replace the roller assembly. JD sells a service kit with the rubber roller, bearing races, and mounting hardware. Cost is typically $180–$280 in parts, and it’s a 45-minute installation. This is a common enough issue that used replacements are also available on the aftermarket.

Time to fix: 45–75 minutes. Cost: $180–$280 in parts (plus labor if using a dealer).

Failure #6: Net jumps over counter knife (467 and 469)

The wrap feeds but doesn’t track over the counter knife correctly. It bunches to one side or simply jumps over the knife, and the cut never happens.

What to check: Look at the counter-knife path (the stationary blade that the wrap feeds across). Is it bent, misaligned, or coated with buildup? The wrap track tension should pull the wrap flat against the counter knife. If the tension is loose or the counter-knife tracking is off by more than 1/4 inch, the wrap will jump.

Why it happens: On 467s and 469s, the counter-knife mounting is relatively loose to allow feed adjustment. Impact from rocks in the bale or from aggressive operator use can bend the mounting. Wrap buildup on the counter knife also changes the effective profile and causes misalignment.

The fix: Clean the counter-knife thoroughly with a putty knife and rubbing alcohol. Check the mounting bolts—they often loosen after hundreds of operating hours. If the counter knife is visibly bent, it can usually be re-bent using a rubber mallet (carefully) or replaced. Replacement is cheaper: $60–$120 for the knife.

Time to fix: 15–30 minutes for cleaning and bolt check, 30–60 for replacement. Cost: Free to $120 depending on whether replacement is needed.

Failure #7: Twine arm and net wrap actuator wiring failures (567 early models)

On early 567 production runs, the wiring harness from the control box to the net actuator has two known failure points: the connector at the actuator can corrode (especially in wet regions), and the wire insulation in the harness can chafe where it passes a sharp frame edge.

What to check: With the monitor armed, trigger a wrap cycle and listen for a relay click in the monitor. If you hear the click but the actuator doesn’t move, the wiring between monitor and actuator is open. Inspect the plug at the actuator — is it green or white (oxidation)? Follow the harness from the monitor to the actuator and look for chafing or exposed wire.

Why it happens: JD revised the wiring harness design around 2010 after reports of intermittent wrapping on early 567s. If your 567 is pre-2010, you have the original harness—which is known to fail. Post-2010 models have a rerouted harness with better protection.

The fix: Clean the connector at the actuator with contact cleaner and a pencil eraser (gently). Reseat the plug firmly. If the wire is chafed, wrap the damaged section with electrical tape. If the connector is severely corroded, replace it—a replacement connector kit is typically $30–$60. If chafing has exposed wire, the harness should be rerouted or replaced.

Time to fix: 15–45 minutes. Cost: $0–$60 depending on root cause.

Failure #8: Wrap rolling on the feed roller or wrapping around bearings (566 / 535 / general)

The wrap escapes the wrap-feed path and wraps around drive components, bearing housings, or the feed roller itself. This is a mechanical-feed-speed mismatch, not an electrical problem. The wrap rolls onto itself instead of feeding flat.

What to check: Open the hood and watch a complete wrap cycle from outside the baler. Does the wrap feed smoothly and flatly across the bale? Or does it bunch, roll, or twist onto itself? Check that the wrap-feed path guides and rollers are aligned and not damaged.

Why it happens: On 566 and 535 models especially, if the wrap-feed roller bearing is worn or the roller itself is misaligned, the wrap doesn’t feed perpendicular to the bale. Feed tension becomes uneven, and the wrap rolls instead of sliding. The issue is compounded if the wrap is under-tensioned (wraps-per-bale set too low).

The fix: First, check the wrap-feed roller bearing. If it has play (rock it side to side with your hand), the bearing is worn and the roller needs replacement. Bearing wear is common on balers over 20 years old. Second, increase the wraps-per-bale setting by 0.25 to 0.5 turns — this increases feed tension and often solves rolling. If both checks pass and the problem persists, the baler frame may be bent (possible after impact damage) — this is a dealer diagnostic.

Time to fix: 15–45 minutes for bearing/tension checks, 2–4 hours if bearing replacement needed. Cost: Free to $400 depending on scope.

Model-by-model quick reference

Use this table to identify which failure modes are most common on your specific Deere baler model:

When to call the dealer

• Monitor displays a fault code with no obvious wiring break. Bring the code, the model year, and the conditions when it appears. Dealers can pull the service history from the monitor.
• You’ve replaced the actuator and the problem persists. The issue is likely in the pan mounting or the monitor relay. Let the dealer pull and test the relay.
• The hydraulic system won’t hold pressure. Slow tailgate, weak bale chamber, soft driveline — these require a pressure gauge and are best diagnosed by a dealer tech.

The takeaway

John Deere round balers have eight common net-wrap failure modes, and six of them can be diagnosed and fixed by an operator in an hour or less. Start with the quick checks: look for rust under the dispenser, test the actuator voltage drop, measure monitor voltage, and increase wrap tension by half a turn. If those don’t solve it, the solution is almost certainly one of the remaining failures—all of which are documented in AgTalk threads with working fixes. Use the complete net-wrap-won’t-cut diagnostic flow in conjunction with this guide to narrow down the cause. When in doubt, run back through the low-voltage check: more Deere operators end up replacing perfectly good actuators because they wired to the convenience outlet than for any other reason. Fix the power, fix the problem.
