At Lone Star Trailer Services, we know grain trailers are the workhorses of agriculture and bulk hauling — running nonstop during harvest season and demanding reliability all year round. When your grain trailer shows signs of wear, leaks, or mechanical issues, you need repairs done fast and done right.

Our technicians specialize in complete grain trailer service and repair, from hopper gates and hydraulic systems to frame welding and tarp replacements. Whether you run a Wilson, Timpte, Merritt, or any other make, we’ll keep your trailer field-ready and DOT-safe.

Hopper & Gate Repairs

The hoppers and discharge gates are some of the hardest-working parts of any grain trailer. Dirt, moisture, and constant use can wear them down fast. Lone Star provides:

• Hopper patching and replacement for cracked or corroded panels

• Gate door repair or replacement (manual and hydraulic types)

• Handle and linkage repair for smoother opening and closing

• Gate roller and track maintenance to eliminate binding

• Seal replacement to prevent leaks during transport

• Auger system repairs for trailers equipped with grain augers

We make sure your hopper system flows smoothly, seals tightly, and performs reliably load after load.

Hydraulic and Pneumatic System Repairs

Many modern grain trailers use hydraulic or pneumatic controls for ease and safety. We repair and rebuild:

• Hydraulic cylinders and valves for leaking or weak systems

• Airline leaks and fittings

• Gate control valves and switches

• Air bag suspension systems

• Hydraulic motors and pumps for unloading equipment

Every system is pressure-tested and calibrated for consistent, safe operation.

Frame, Structure & Body Repairs

Years of field use, rough roads, and heavy loading can cause frame fatigue or damage. Our technicians specialize in:

• Cracked or bent frame rail repair and reinforcement

• Crossmember and subframe replacement

• Hopper support and bolster plate repairs

• Landing gear and kingpin plate repairs

• Front wall and bulkhead reinforcement

Our welding and fabrication team can restore your trailer’s strength and structure to like-new condition.

Electrical & Lighting Repairs

Electrical systems take a beating in dusty, dirty, and wet conditions. Lone Star provides:

• Complete trailer rewiring

• Light replacements (marker, clearance, stop, and turn signals)

• Connector plug and harness replacements

• Backup light and indicator diagnostics

• Weather-sealed harness protection for long-term durability

We make sure every light on your grain trailer works perfectly — keeping you safe and DOT compliant.

Suspension, Axles & Brakes

Heavy harvest loads and rural terrain put extra strain on suspension and braking systems. We repair and maintain:

• Leaf springs, hangers, and bushings

• Airbag suspension systems

• Wheel bearings, seals, and hubs

• Brake shoes, drums, and air brake lines

• ABS sensors and valves

• Axle straightening and alignment

We keep your grain trailer rolling true, stopping safely, and performing reliably in any condition.

Tarp Systems & Ladders

Keeping grain dry and accessible is essential. Lone Star repairs and installs:

• Electric and manual tarp systems

• Tarp bows, cranks, and support rods

• Roller bar and spring mechanisms

• Tarp motor and switch replacements

• Ladder and catwalk repair or replacement

We use heavy-duty tarps and components built to withstand the toughest conditions.

Miscellaneous Repairs & Upgrades

We handle everything that keeps your trailer ready for the next haul:

• Air valve and gladhand replacements

• Mudflap brackets and fenders

• Grain chute extensions and spout repairs

• DOT inspection preparation and compliance checks

• Custom fabrication for older or modified trailers

If it’s part of your grain trailer, we can fix it.
