5 Reasons Why Your Netwrap Isn’t Cutting Cleanly (and How to Fix It)
Netwrap that won’t cut cleanly can quickly disrupt a baling operation. The good news is that there are some “usual suspects” when it comes to netwrap cutting problems. In this guide, we walk you through the most likely issues and explain how to fix them and get baling back on track.
1. Dull or damaged cutting knife
One of the most common causes of netwrap problems is a dull or damaged cutting knife. A worn or chipped blade typically tears the net instead of cutting it cleanly, leaving ragged edges and causing the net to snag. This can prevent the net from covering bales properly, leaving the edges exposed. In the worst cases, the netting can jam up internal components, such as rollers and chains.
The fix: In most cases, the knife simply needs to be removed and sharpened. Before doing this, make sure the baler is switched off and safely locked out. If the blade is badly damaged, you may need to replace it. In both cases, consult your baler’s operator’s manual for instructions on how to remove and work on the blade safely.
2. Debris in the cutting area or dirty rollers
Crop residue, dust, or net fibres wrapped around the blade are another common source of bale netwrap problems. Debris can prevent the knife from moving freely or making full contact with the net or anvil. Dirty rollers can also cause the net to slip or pull as it feeds, contributing to cutting problems.
The fix: Regularly inspect and clean your rollers, knife, and other areas that come into contact with the netwrap. Keeping on top of debris buildup is one of the easiest ways to keep baling moving along without a hitch.
3. Incorrect tension or brake settings
If your net isn’t cutting properly (or at all), check your tension and feed roll brake settings. Net that’s too loose may fail to cut or cut unevenly. Net that’s stretched too tightly may break or tear during cutting. Either way, you risk the netwrap bunching or stretching in a way that means your bale isn’t properly protected.
The fix: Check your baler’s operator’s manual to ensure the tension and brake settings are correct. Also check that brake components, such as pads or springs, are in good condition and working properly. Regular servicing can prevent problems before they occur.
4. Mechanical faults
Check whether your knife moves properly and connects with the net. The knife needs enough force and a full range of motion to cut evenly. Anything that interferes with this, such as weak springs, a faulty actuator, damaged wiring, or worn pivots or pins, can result in partial or missed cuts.
The fix: In some cases, worn or damaged components can simply be replaced. However, fixing other mechanical faults, particularly those involving wiring, may take some detective work. The correct procedure depends on your baler’s make and model. As a starting point, run a diagnostic test of your actuator’s response according to the instructions in your operator’s manual. If that doesn’t solve the problem, contact a dealer or service centre.
5. Poor quality (or degraded) netwrap
The quality of your netwrap plays a big part in performance. Poor quality products are more prone to breakage or tearing, even at standard baling settings. The risk increases when netwrap is stored outside and exposed to the elements.
The fix: High quality round bale net wrap is designed to perform under pressure and withstand a wide range of environmental conditions. However, even top quality products need to be stored properly at the end of the season. This ensures they’re ready to use when the next baling season rolls around and minimises the risk of problems once you start working.
