Specifications

Project: Purchase of 15-foot Planter and Grain Drill

GENERAL INFORMATION

1.0 Scope of Work:

Provide row-crop planter and grain drill for planting multiple kinds of crops in research plots and small production fields. Both must be flexible to quickly change crops, varieties, and populations and perform in a variety of soil and field preparation conditions. Planter must be vacuum or positive pressure regulated, include fertilizer application, and include row-unit monitoring for blockages, singulation, and populations. Drill must include both large- and small-seeded boxes. Row units and openers must work in heavy, wet, and stony soils with both minimal and extensive tillage and moderate residue. Can be used.

CONTRACTOR REQUIREMENTS

2.0 Technical Requirements/Tasks:

CLIN 0001 – Row Crop Planter
