How Do You Open Your Silage Bales? Manual, Mechanical, and Innovative Methods

How Do You Open Yours?

Opening silage bales; the methods, the machinery and the mistakes to avoid

Every farmer has their own way of opening a silage bale.

Some swear by a knife. Others wouldn’t feed cattle without a shear grab. And increasingly, machinery choice (and even the type of bale binding used) is influencing how easily and safely bales can be opened at feeding time.

With silage remaining the core forage crop across Ireland, bale handling doesn’t end when the wrapper leaves the field. In reality, how a bale is opened can affect labour efficiency, feed quality, safety and plastic waste management every single day of winter feeding.

So, borrowing a famous question…..how do you open yours?

The Manual Method….

For many farms, bale opening still starts with the tried and tested penknife or safety blade.

Typically, the bale is lifted on the loader, plastic wrap is cut away, and the silage is either rolled out or placed into a feeder.

Advantages

• No additional machinery investment
• Flexible in tight yards or older buildings
• Works for occasional feeding

Disadvantages

• Time consuming for larger operations
• Increased physical effort
• Plastic removal can be messy in poor weather
• Higher safety risk

One of the biggest concerns arises when operators cut plastic beneath a raised bale. A suspended bale weighing over 700kg presents a serious hazard if loader movement or hydraulic failure occurs.

Health and safety advisors consistently recommend keeping operators clear of raised loads wherever possible.

Open Once, Feed Later…

Another common approach is removing packaging in the yard or shed before feeding.

Some farmers remove outer stretch wrap but leave net in place until the bale reaches the feeding area or in field ring feeder.

This method reduces plastic blowing around fields and simplifies waste collection.

Importantly, this system works best where netwrap or modern alternatives like EZ Web are used. The bale retains its structure once the stretchfilm is removed, allowing safe transport across yards or fields before feeding.

With film-on-film (NRF) systems, this flexibility is largely lost; once outer film is removed, bale stability can quickly deteriorate, making relocation difficult.  And that is assuming you can easily remove the outer stretchfilm without damaging / accidentally removing the inner net replacement film.

Mechanical Opening….Shear Grabs & Bale Handlers

As herd sizes grow, mechanical opening systems are becoming increasingly common across Irish farms yards.

Bale shears and grabs allow operators to:

• Lift
• Split
• Open
• Feed

…..all from the comfort of the tractor seat.

Under Targeted Agricultural Modernisation Scheme (TAMS 3), grant aid is currently available for bale handling equipment (as at Feb ’26), helping offset investment costs for approved machines.

Two Main Systems

1. Hook or Spike Systems

Hooks pierce the bale while a blade cuts the plastic.

Pros

• Lower purchase cost
• Simple design
• Fast opening

Cons

• Can disturb bale structure
• Greater risk of silage tearing
• Plastic removal still partly manual

2. Clamp / Shear Grab Systems

Clamp style shears hold the bale securely while hydraulically cutting and separating material.

Pros

• Cleaner opening
• Improved silage presentation
• Reduced waste contamination
• Safer operator position
• Ideal for high volume feeding

Cons

• Higher initial investment
• Requires suitable loader capacity

Irish farmers now have access to a wide range of manufacturers offering TAMS approved bale shears, reflecting how feeding efficiency has become just as important as harvesting efficiency.

Why Bale Binding Matters at Feeding Time

Opening efficiency doesn’t just depend on machinery, it starts with how the bale was bound in the first place.

Where netwrap or systems such as EZ Web are used:

• Plastic can be removed cleanly
• Bales remain stable during handling
• Transport after unwrapping is possible
• Feeding workflow is more flexible

Film only binding systems can complicate opening, particularly when operators want to remove wrap away from livestock areas or transport partially opened bales. If, however, they want to feed where they open, then NRF, when combined with a bale splitter, can give you a fast removal.

In short, harvest decisions often show their true impact months later when feeding out.

Safety First….A Reminder Worth Repeating

Regardless of method, several risks appear repeatedly on farms:

• Cutting plastic beneath raised bales
• Handling loose wrap in windy conditions
• Manual lifting of heavy wet plastic
• Poor visibility during loader work

Mechanisation increasingly reduces these risks, keeping operators safely in the cab and away from dangerous suspended loads.

So… How Do You Open Yours?

There’s no single right answer.

The best system depends on:

• Herd size
• Feeding frequency
• Yard layout
• Labour availability
• Machinery investment

But one thing is clear, bale opening is no longer just a small daily task. It’s a key part of winter efficiency, safety and silage quality management.

And perhaps the real question isn’t just how you open your bale…

…but whether your baling and binding choices are making that job easier (or harder) every day of the feeding season.

And finally…

If silage were a certain chocolate treat, would you eat the wrapper too?   Daft question, of course not……but what if the wrapper was edible?  Perhaps the ultimate bale opening solution is simple… don’t remove anything at all.

Edible netwrap has attracted growing interest in recent years, promising a system where the binding material can remain on the bale and be safely consumed along with the silage. In theory, this eliminates plastic handling, reduces labour and removes waste management entirely.

Several concepts and early stage products are currently being explored within the industry, you may have even seen some options already on the market.  The idea is understandably appealing, particularly for livestock farmers feeding large numbers of bales every winter.

However, today’s reality is that edible alternatives are not yet scalable for commercial farming. Current options struggle to deliver the strength, consistency and durability required to hold modern high density bales. Longevity during storage, resistance to weathering, and reliable performance through baling, handling and transport remain significant challenges.

As farmers ourselves, we have investigated and tested a wide range of these emerging solutions. While progress is encouraging, none currently match the proven performance, bale integrity or operational reliability delivered by conventional netwrap systems used today.

That said, innovation in this area continues at pace, and so does our evaluation work. The moment we develop a viable edible solution that performs to the same standard as modern netwrap, you can be certain we will share it with our customers first.
