As an authorized Thunderstone dealer, Trison supplies genuine OEM grain cart tarp kits and provides expert assistance in selecting the correct system for your equipment. Simply choose your Cart Width and Cart Length, and we’ll match you with the correct hardware kit.

Why Choose the Thunderstone Grain Cart Tarp Kit?

A grain cart tarp system needs to do two things well: support the tarp properly and operate reliably throughout harvest. Thunderstone combines heavy-duty steel bows, corrosion-resistant aluminum components, and a simple manual crank system to create a durable tarp system that’s easy to operate and built for years of field use.

Unlike lightweight systems that can allow the tarp to sag over time, properly supported tarp bows help keep the tarp positioned across the grain cart, reducing unnecessary wear while making the system easier to open and close.

What’s Included

Each kit is sized for the grain cart dimensions you select and includes the hardware required to install the tarp system, including:

• Aluminum tarp caps
• Heavy-duty tarp bows
• Heavy-duty bow brackets
• Aluminum latch plate
• Roll tube hardware
• Pinless crank retainer with 11″ standoff
• Stretch cord return
• Recessed tarp stops
• Mounting hardware

Everything is matched to the selected cart width and length, so you receive the correct hardware configuration for your grain cart.

What’s Not Included

• The replacement tarp is sold separately.

Built for Reliable Harvest Performance

Heavy-Duty Tarp Bows

Heavy-duty steel bows support the tarp across the grain cart to help prevent sagging, especially as the tarp ages. Proper support also reduces stress on the tarp during opening and closing, helping extend its service life.

Aluminum Tarp Caps

Aluminum tarp caps won’t rust like painted steel components, making them ideal for equipment that’s exposed to rain, fertilizer, and long harvest seasons.

Heavy-Duty Bow Brackets

Strong mounting brackets keep the bows securely positioned, helping maintain proper tarp support even after years of field use.

Aluminum Latch Plate

The aluminum latch plate provides a durable attachment point while resisting corrosion in outdoor environments.

Pinless Crank Retainer with 11″ Standoff

The pinless design lets you remove and store the crank handle quickly without dealing with retaining pins, making daily operation faster and more convenient.

Stretch Cord Return

The stretch cord helps maintain consistent tarp tension as the tarp rolls open and closed, improving operation and helping the tarp stay properly positioned.

Recessed Tarp Stops

Recessed tarp stops help keep the tarp aligned during operation while reducing unnecessary wear on the tarp and hardware.
