Every harvest pass counts when you’re racing the weather or chasing daylight. The Big Top™ combine hopper extension from Crary Industries helps you make the most of every trip through the field — by increasing your combine’s grain tank capacity and reducing unload stops.
🚜 What is Big Top™?
Crary’s Big Top is a rugged, collapsible extension designed to fit most major combine brands and models. With Big Top installed, you can increase your combine’s hopper capacity by 50 to 100 bushels or more, depending on the configuration.
That means:
- Fewer unloads
- Less downtime
- More acres per hour
And when it’s time to transport or store the machine, the sides fold down — keeping it within legal height and width limits.
⚙️ Key Features
- Custom Fit for Most Brands – Including John Deere, Case IH, New Holland, AGCO, and more.
- Steel Frame + Canvas Sidewalls – Strong and lightweight construction.
- Built-In Viewing Windows – Keep an eye on tank fill level from the cab.
- Weather-Ready Cover Options – Optional tarp kits help keep grain dry during sudden showers or overnight.
The canvas sidewalls collapse quickly using Crary’s reinforced latch and cable system — making it easy to go from field-ready to road-ready in minutes.
💬 What Farmers Are Saying
“With the Big Top on our S780, we’re able to push longer before unloading. That extra 90 bushels adds up when you’re trying to finish a section before rain hits.”

💲 Why It Pays Off
Time saved during harvest is money earned. Big Top helps:
- Cut the number of unloads by 10–20% or more per day
- Maximize grain cart and truck timing
- Reduce soil compaction from fewer field passes
- Keep your combine running at peak efficiency
When every minute counts, staying in the seat just a little longer makes a big difference.
👨🌾 Final Word
If you’re running a late model combine and looking to gain an edge without spending six figures on a new unit, a Big Top hopper extension is a smart, affordable upgrade. It’s the kind of simple improvement that pays off in both time and productivity — and that’s what we like to spotlight here at FarmingEquipment.com.
