John Deere B-Wrap promises something every hay producer with too many bales and too little barn wants to hear: barn-quality hay without the barn. It's real technology, it works, and farmers who've tried it on the right crop will tell you it does what it claims. It's also one of the most expensive ways to wrap a bale — and it comes with a catch that the sales pitch tends to skip.
This is an honest, farmer-sourced look at what B-Wrap actually is, what it really costs per bale (not per roll), the top-versus-bottom spoilage problem nobody mentions, and the cheaper ways to get most of the same protection. We manufacture net wrap, so our bias is on the table — but the conclusion here is the same one the producers in these threads reach on their own.
Quick answer: B-Wrap is a John Deere/Tama product — a breathable, water-shedding film bonded into a roll of net wrap — that lets you store round bales outside and keep them close to barn quality. It works, but it's expensive: recent dealer pricing runs roughly $6–$10 a bale versus about $1–$3 for standard net wrap, a roll only covers about 35 bales, and it needs a dealer-installed kit on a John Deere 7/8/9-series baler (no New Holland or AGCO equivalent). The big catch: B-Wrap protects the top of the bale, but most outdoor spoilage comes from the bottom — so if you're stacking on bare ground, base prep matters more than the wrap. For most operations, standard net wrap + an off-ground base + a tarp, or simply feeding within a year, gets you most of the protection for a fraction of the cost. B-Wrap earns its price on high-value hay you're storing outside and selling.
What B-Wrap actually is
B-Wrap isn't a separate machine or a coating you spray on. It's a special roll of net wrap with a breathable film built into it, and it runs through a John Deere baler almost like ordinary net. One producer who sat through a John Deere dealer presentation described the mechanism better than any brochure:
"B-wrap is basically a special roll of netwrap that has breathable film bale sleeves attached to the netwrap itself. When the baler starts the netwrap cycle, a turn and a half of netwrap enters the baler and wraps the bale in the standard way; as the wrap continues to feed, the breathable film sleeve… completely encapsulates the bale across the width of the net with a waterproof, breathable sleeve of material… They advertise it as 'barn kept hay without the barn.'"

The clever part is the film itself. It's micro-porous: it blocks liquid water (rain, snow, ground splash) from getting in, but it lets water vapor escape from inside the bale. That matters because the obvious DIY version — wrapping a bale in solid plastic film — traps the moisture every hay bale sweats out after baling, and you get a slimy layer of white mold against the plastic. B-Wrap's breathable membrane is designed to wick that internal moisture out while keeping outside water off, which is why it can hold hay close to barn quality outdoors.
Mechanically, it requires a dealer-installed kit and a sensor on a John Deere 7-, 8-, or 9-series (and newer Zero Series) baler. Once that's on, you can swap between a roll of B-Wrap and a roll of regular net wrap in about the time it takes to change net — so you can run B-Wrap on your best hay and plain net on everything else. As of 2025 it's still sold through John Deere and Tama early-order programs; it has not been discontinued.
What it costs — per bale, not per roll
Here's where the enthusiasm meets the checkbook. B-Wrap's sticker is deceptive because a roll covers far fewer bales than a roll of net wrap. The extra thickness of the film means a roll only wraps about 35 bales, where a roll of standard net does 120–175 or more. Recent dealer pricing puts a roll around $350–$390, so the wrap alone works out to roughly $6–$10 per bale depending on bale size — against about $1–$3 per bale for standard net wrap. On top of that is the one-time baler kit.
Producers in these threads are blunt about the math, and they make an important point: you have to figure it per ton, not per bale, because B-Wrap is set up for taller bales:
"$8.00 per bale plus $350 for the baler kit… the B-wrap is for a 66" tall bale requiring more bales to be made, so you better figure the cost per ton not by the bale. My cost on the same size bale with netwrap… is .94 per bale. Hmmm, $2–3 a bale for netwrap — the guy is exaggerating the cost of netwrap. Even JD netwrap doesn't cost that much."
— swmnhay · HayTalk thread 62529
That "build a shed instead" comparison comes up again and again, because at volume the numbers favor the building:
"I could only wrap 35 bales before having to change. On top of this fact, at a cost of $8 a bale I could pay for a damn good barn when rolling 2,000 bales a year — even if I only put half of it under the barn."
— Circle MC Farms · HayTalk thread 62529
The honest read: B-Wrap is priced like a premium tool, and at any real volume the cost approaches the cost of permanent storage. That doesn't make it wrong — it makes it a tool for specific situations, not a default.
The catch nobody mentions: it protects the top, not the bottom
This is the single most useful thing in any B-Wrap discussion, and it's the part the sales presentation glosses over. Most outdoor round-bale spoilage doesn't come from rain landing on top — it comes from moisture wicking up out of the ground into the bottom of the bale. B-Wrap sheds water off the top and sides. It does nothing about the ground.
"Most RB spoilage is from the bottom. B-wrap protects the top, so whether you use it or not doesn't make sense if you are stacking on the ground. Now, if you are stacking on a pallet, stopping bottom moisture migration, then B-wrap on top is a different story. At the price of B-wrap, you are just speeding up the 'paying for a hay shed' quicker."
— r82230, Thumb of Michigan · AgTalk thread 965571
One producer's hands-on test is a cautionary tale about exactly this:
"What bales we did make ended up holding water in the bottom of them much worse than the regular wrap on both adjoining rows. Those bales ended up being the cheapest hay I've ever sold at an auction in 25 years. Never used B-Wrap again."
— RFI90, Northeast Iowa · AgTalk thread 965571
The takeaway isn't "B-Wrap is bad" — it's that B-Wrap only pays off if you've already solved the bottom. If your bales sit on bare dirt or sod, the cheapest, highest-return move is getting them up off the ground on a free-draining base — gravel, pallets, old tires, or a crowned pad — before you spend a dime on premium wrap. Our round-bale storage base-prep guide walks through how to do that, and it does more for outdoor keeping quality than any wrap upgrade.
The other real-world drawbacks
Beyond cost and the bottom-spoilage issue, producers who've run B-Wrap raise a few practical headaches worth knowing before you buy the kit:
- Every bale has to be set down perfectly. The film wraps the bale's circumference, leaving the cut ends as the weak point. If a bale rolls too far when it's dumped, the film edge can turn up and funnel runoff into the bale instead of off it. As one producer put it: "every bale has to be set perfectly… if a bale were to roll too much the edge of the b-wrap end would be turned up catching the rain that ran off the bale."
- Heavy rolls, changed often. Thirty-five bales per roll means a lot of roll changes on a big day, and B-Wrap rolls are heavier than net. "They're heavy rolls to be changing that often," as RFI90 noted.
- John Deere only. B-Wrap is proprietary to John Deere balers with the kit installed. As of the 2025 discussion, there's still no New Holland or AGCO/Massey equivalent — so if you don't run a compatible Deere, it's a non-starter.
- It doesn't fix the ends or a bad bale. Soft, out-of-round, or loosely wrapped bales don't seal well no matter what's on the outside.
When B-Wrap genuinely makes sense
For all the skepticism, B-Wrap has a real niche, and the same farmers who won't put it on grass hay will defend it for the right job. It earns its premium when all of these line up:
- The hay is high-value — quality alfalfa, dairy hay, or premium horse hay where a few dollars of wrap protects a lot of dollars of forage.
- You're storing it outside and selling it — you don't have barn room, and the bale needs to still look and smell fresh to a buyer months later.
- The crop is storage-vulnerable — peanut hay, cornstalk bales, sorghum-sudan, and straw don't shed rain the way a tight grass bale does, so they gain the most from a water-shedding skin.
- You're in a wet climate where outdoor bales take a real beating.
The classic endorsement is that cattle themselves vote for it — fed a regular-net bale and a B-Wrap bale from the same field, side by side, they'll clean up the B-Wrap hay first because it kept fresher. Even a B-Wrap skeptic conceded the point for the right crop:
"At $6 a bale, there is no way to justify it for grass hay. I could certainly see it being good for peanut vine, as it doesn't form a thatch and is very susceptible to moisture intrusion… it does keep it better — that's a fact, and an expensive one at that."

The cheaper ways to get most of the same protection
If you don't fit that niche, there are well-proven, far cheaper paths to good outdoor keeping — and they're what most of these producers land on:
- Standard net wrap + a proper base + a tarp. A tight, fully net-wrapped bale already sheds a surprising amount of weather on its own (that's net wrap's core job — see net wrap vs twine). Get the bales off the ground, and throw a tarp over the high-value rows. Our hay-bale tarp selection guide and guide to storing net-wrapped bales outside cover the combination that protects top and bottom for a fraction of B-Wrap's cost.
- Feed it within the year. A well-net-wrapped bale on a good base, fed before the next summer, rarely needs more than that — especially in drier climates where, as one Texas producer noted, the annual spoilage is cheaper than the taxes on a new building.
- Build or lease covered storage if you bale at volume. The math the threads keep returning to: at thousands of bales a year, premium wrap money is shed money. "It would be cheaper to build a shed if you baled any amount of hay."
- If it's the weather you can't beat, consider baleage instead. If the real problem is that hay won't dry, wrapping wet (baleage) may solve more than dressing up dry bales — sometimes for less per bale, as one producer pointed out: "you would be better off using an inline wrapper at $3 per bale and putting up baleage."
For the everyday wrap that does the heavy lifting in all of those paths, XES Extreme net wrap is the value choice: full edge-to-edge coverage that sheds weather and holds bale shape, at a per-bale cost that leaves room in the budget for the base and the tarp that actually protect the bottom.

Is B-Wrap biodegradable?
Short answer: no. Because it's marketed as a "premium" wrap, B-Wrap is one of the most-searched products on this question, but it is a film-coated polyethylene wrap — not biodegradable and not compostable. The residue is the same persistent plastic as regular net wrap, so you still have to collect and dispose of it. We cover that in detail in our guide to biodegradable net wrap.
Frequently asked questions
What is John Deere B-Wrap?
B-Wrap is a John Deere/Tama product: a roll of net wrap with a breathable, micro-porous water-shedding film built into it. As the bale is wrapped, the film encapsulates it in a sleeve that blocks outside rain, snow, and ground splash while letting the bale's own moisture vapor escape — keeping outdoor-stored hay close to barn quality. It needs a dealer-installed kit and sensor on a compatible John Deere baler.
How much does B-Wrap cost per bale?
Recent dealer pricing runs roughly $6–$10 per bale, versus about $1–$3 per bale for standard net wrap. A roll only covers about 35 bales (versus 120–175+ for net wrap), and there's a one-time baler kit on top. Producers stress figuring the cost per ton, not per bale, because B-Wrap is set up for taller bales.
Is B-Wrap worth it?
It's worth it for high-value hay you're storing outside and selling — quality alfalfa, dairy or horse hay, or storage-vulnerable crops like peanut, cornstalk, and straw — especially in wet climates. For ordinary grass hay, or any operation at volume, standard net wrap plus an off-ground base and a tarp, or simply feeding within the year, gets most of the protection for far less, and at scale the premium-wrap money approaches the cost of a shed.
Does B-Wrap work in New Holland or other balers?
No. B-Wrap is proprietary to John Deere balers (7-, 8-, 9-, and Zero Series) with the dealer-installed kit. As of 2025 there is no New Holland or AGCO/Massey Ferguson equivalent, so it's only an option if you run a compatible Deere.
Can you store B-Wrap bales on the ground?
Not effectively. B-Wrap sheds water off the top and sides, but most outdoor spoilage comes from ground moisture wicking into the bottom of the bale — which B-Wrap does nothing about. Producers report B-Wrap bales holding water in the bottom worse than regular bales when set on bare ground. Get bales up on a free-draining base first; that does more for keeping quality than the wrap upgrade.
This guide is maintained by the XES Netting team. We manufacture bale net wrap, so we have a stake in this comparison — but the figures and experiences above come from producers who actually ran B-Wrap, and the bottom line is theirs as much as ours: it's a real tool for a specific, high-value job, not a default. Dealer pricing changes; confirm current B-Wrap and net-wrap prices with your dealer before you decide.
