Minimum Order Quantity (MOQ) is another critical cost driver. The observed MOQ range is between 1 and 50 units. This flexibility allows buyers to procure single units for pilot testing or small farms, while larger agricultural cooperatives or distributors can negotiate bulk pricing for orders approaching the upper limit. Customization is a significant factor in cost escalation. The data confirms that "Customization" is available and that OEM & ODM services are accepted. Buyers seeking specific color schemes, custom branding, or modified mechanical configurations should anticipate a price premium and a longer lead time.

Packaging standards also affect the final landed cost. Options range from "Standard Export Packaging" to "Unpacked" configurations. Standard export packaging typically includes protective wrapping and crating to prevent damage during international shipping, which adds to the unit cost but reduces the risk of transit damage. Unpacked units may be cheaper but require the buyer to arrange for their own packaging and protection, potentially increasing logistics costs and risk.

Typical Applications and Field Versatility

The application scope of combined excavating shovel potato harvesters is broad, extending beyond simple potato harvesting. The observed data lists applications for Rice, Wheat, Corn, and Tubers, indicating that these machines are often multi-purpose or adaptable to various crop types. The primary application field is categorized as Agriculture, but the data also includes Forestry, Livestock, and Aquaculture. This suggests that the machinery may be used for clearing land, harvesting fodder, or managing vegetation in diverse agricultural settings.

The harvesting range is specified as 165-190 cm, which is a critical metric for determining the machine's coverage per pass. A wider harvesting range generally translates to higher efficiency, reducing the time required to harvest a given area. The machine type is identified as a "Portable Harvester" or "Combine Potato Harvester," suggesting versatility in deployment. Some models are designed as backpack units for small-scale or difficult terrain, while others are larger, tractor-mounted units for expansive fields. The grass cutting disc size, observed at 750mm, further highlights the machine's capability to handle vegetative debris alongside tuber harvesting.
