Grain Cart Tarp & Component Maintenance: How to Ensure Optimal Performance This Harvest Season

At Syntex Industries, we know your grain cart is one of the hardest-working pieces of equipment in your harvest lineup. When running at peak performance, it saves time, reduces downtime, and prevents costly repairs. But to get the most out of your equipment, consistent, well-rounded maintenance is non-negotiable.

From your tarp system to your driveline components, track wheels, and vertical auger, every moving part plays a role in your overall performance. This guide walks you through what to inspect, when to replace, and how to protect your investment as harvest season ramps up.

1. What Are the Main Replacement Parts for Maintaining a Grain Cart Tarp?

Your tarp protects your load—and your time. But tarp systems wear down under the pressure of the elements and heavy use. So, what are the main replacement parts for maintaining a grain cart tarp?

• Tarp fabric: Watch for tears, heavy cracks, and UV ray damage—especially around cart side panels and high-wear seams.
• Electric tarp motor (or manual crank): If your electric tarp struggles or stalls, it might be time to replace the motor. Decide whether a manual or electric tarp is best based on convenience and budget.
• Tarp bows and brackets: Bent or rusted supports compromise fit and function.
• Mounting hardware: Bolts, clips, and can corrode or loosen over time.

We recommend storing your tarp in a dry place, inspecting your tarp regularly, and checking for other visible damage before each use.

2. Driveline Components: Don’t Overlook the Power Behind the Cart

Your grain cart’s driveline components are the unseen force that keeps your load moving. Ignoring them can lead to significant wear or worse—failure during harvest.

• Inspect rotating drive shaft assemblies and rotating drive shaft connecting joints for wear spots and play.
• Ensure power shaft guards are intact and working properly.
• Look for worn driveline components and listen for vibration or grinding.

Lubrication is key. Follow your owner’s manual for all lubrication points and keep everything adequately greased to reduce extra strain.

3. Auger System: Inspect Bearings and Grain Transition Areas

Your vertical auger and upper vertical auger are responsible for grain flow. Slow unloading? It could be a pto vertical auger bearing on its last leg.

Also inspect:

• Grain transition areas for clogs, cracks, or material buildup
• Grain transitions for signs of obstruction or corrosion
• Belt and chain condition for proper rotation and wear

Routine checks here ensure your grain unloads quickly and cleanly—no surprises in the field.

4. Tracks & Tires: Check Alignment, Pressure, and Frame Integrity

Your cart’s main track frame, track wheels, and wheel bearings absorb a ton of stress. Misalignment or loose nuts can shift your cart’s weight dangerously and affect mobility.

• Check track alignment frequently—especially after the previous season
• Maintain tire pressure and inspect wheel nuts for torque
• Look for damage or slippage in the track alignment

Keep an eye on your belt tension as well. Over-tightened belts wear faster and under-tensioned belts slip—both of which affect optimal performance.

5. Frame, Hitch, and Safety Hardware: The Backbone of Your Cart

Your frame, hitch, and hardware provide the structure that holds it all together. Failure here can be catastrophic—and completely preventable.

• Examine the frame for visible damage, heavy cracks, or dirt and debris buildup
• Replace any worn draw bar hitch pins, bar hitch pins, or clevis hitch components
• Double-check safety chains, turn signals, and slow-moving vehicle signs for road travel

Inspect axle bolts and gearboxes for stress and ensure gearbox oil level is properly calibrated.

6. Hydraulics, Harnesses & Electrical: Small Issues, Big Problems

Your hydraulic hoses and electrical harnesses are often out of sight—and out of mind. But even minor leaks or frays can result in downtime.

• Inspect harnesses for wear, frays, or exposed wires
• Look for hydraulic leaks, loose fittings, or dry rot in hydraulic hoses
• Clean and secure connections to ensure proper function

Review your maintenance recommendations and stay ahead of issues that impact your equipment’s good operating order.

7. Visual Inspection & Pre-Harvest Checklist

Before the combines roll, do a full walkaround. A solid visual inspection can catch most problems early.

• Repack and repack bearings annually, especially in high-wear areas
• Ensure all parts are properly fitted and free from visible damage
• Use a trade scale to monitor cart weight and verify even load distribution

Following your owner’s manual will help you prioritize critical inspection points and keep everything in good condition.
