FIELLDAY Sunflower Header: ZhSU-600 or ZhSU-740 - How to Choose

The sunflower header catalog features two FIELLDAY models with different cutting widths - the ZhSU-600 (6 meters) and the ZhSU-740 (7.4 meters). The price difference is significant, so it's worth figuring out which model actually matches the scale of your farm.

The Main Difference: Cutting Width and Productivity

The ZhSU-600 covers 6 meters per pass, while the ZhSU-740 covers 7.4 meters. At first glance the difference looks small, but on large fields it translates into significant time savings - fewer passes across the field means less fuel burned and finishing harvest faster within a narrow agronomic window.

Combine Power Requirements

The wider ZhSU-740 feeds a larger volume of plant material into the threshing mechanism per unit of time. Before choosing a model, be sure to check whether your combine can consistently process this volume without becoming overloaded - an underpowered machine won't let you fully take advantage of the wider cutting width.

When the ZhSU-600 Is Enough

• your sunflower acreage allows you to finish harvest within a comfortable timeframe even with a narrower cutting width;
• your combine's threshing capacity is limited and not built for maximum load;
• your farm wants to minimize upfront equipment investment.

When to Consider the ZhSU-740

• large acreage, where every day saved on harvest directly affects yield quality and volume;
• a powerful combine capable of fully utilizing the wider cutting width without losing threshing quality;
• the farm plans to offer harvesting services to neighboring farms as well.

The Economics of the Choice

The price gap between the two models is worth considering, but it should be weighed not just against the purchase cost, but also against real savings: fewer hours of field operation means lower fuel costs, less risk of yield loss from weather delays, and freeing up the combine sooner for other tasks during the season.

Bottom Line

The ZhSU-740 justifies its higher cost on large acreages with a powerful combine, where harvest speed directly affects yield preservation. For smaller farms or combines with limited power, the ZhSU-600 remains a rational and fully functional choice.
