Why Should You Maintain Your John Deere Square Baler?

A well-maintained John Deere square baler can quickly and consistently produce high-quality bales without hiccups. The following are just a few of the benefits that come from routine square baler maintenance: 


Balers operate at their best when all parts function correctly. When one part malfunctions, it can have a domino effect on efficiency. For instance, a loose belt could wreak havoc by tangling with other parts, causing stoppages, and speeding up wear. Consistent maintenance boosts reliability, uptime, and performance, which all add up to getting the job done more efficiently.


A regular maintenance routine serves as an early warning system, spotting issues before they harm your baler’s machinery. Small problems can quickly escalate, accelerating wear and tear and shortening your machine’s lifespan. Allocating time and resources to regular maintenance is an investment in prolonging your machine’s lifespan for years to come.


Proactive maintenance is more than just a smart move – it’s a financial win. It spreads out the costs of maintenance over a longer period of time and prevents more costly, avoidable expenses. By ensuring that your baler is operating as it should be, you can also reduce fuel costs and yield more bales in less time.

8 Tips for Maintaining Your John Deere Square Baler

Regular square baler maintenance is more than tightening bolts; it’s an investment in your machine’s efficiency, longevity, and cost-effectiveness. Follow these eight maintenance tips to ensure your baler keeps performing at its best:

1. Maintain and Check Baler Oil

The baler’s oil and air filters should be changed regularly, depending on the environment and the baler’s level of use. Low oil levels, old oil, incorrect oil, and the presence of contaminants can lead to poor lubrication and compromise the baler’s performance. Using the right oil and adhering to the suggested oil change intervals will ensure proper operation and prevent more costly repairs.

2. Observe Proper Cleaning

Cleaning your baler after each use is one of the simplest and most cost-effective ways to protect it. A clean baler is less likely to become contaminated, catch fire, or malfunction. Be sure to clear debris, dust, and crop leftovers, paying special attention to the pickup area and chamber. If you work at a large operation, consider creating a cleaning checklist for your team to follow.

3. Maintain Belts and Chains

Loose or damaged belts and chains can disrupt the baling process and affect bale formation. Check for cracks, tears, proper tension, and alignment. If the belts or chains show any signs of damage, promptly adjust or replace them. By properly maintaining the belts and chains on your baler, you can help to ensure that it operates efficiently.

4. Check Hydraulics and Hoses

Regularly inspect the baler’s hydraulic systems, electric cables, and hoses for leaks, cracks, and signs of wear. Hydraulic issues can lead to malfunctions such as knotter system errors and chamber unresponsiveness, which can affect the baler’s performance and operator safety. When inspecting the hydraulics and hoses, be sure to check that the auto-lube system is working properly and that the tubes haven’t been cut or damaged. Also, regularly change the hydraulic system filters, then run the machine to purge air from the system before use.

5. Make an Inspection Checklist

Daily, weekly, and monthly maintenance is essential for keeping your baler in good condition and preventing serious breakdowns. To stay on top of maintenance needs, create a checklist that specifies the frequency and steps involved in each maintenance task. Your checklist should include tasks related to all key components, such as needles, twine holders, tension springs, and safety shields.
