Features
The model 77C Drill from Haybuster has the ability to plant many different varieties and sizes of seed into all types of planting conditions, ranging from heavy residue no-tillage to minimum tillage and conventional tillage fields.
It plants 7 feet wide and is perfect for smaller wildlife plots and renovating pastures. The 77C is a towable unit and requires just a minimum of 35 hp to operate, depending on terrain and soil conditions.
The two-compartment hopper offers the flexibility of seeding with dry fertilizer, seeding alone, or planting two different seeds.
Standard Features
- Lead Coulter System: Lead coulter blade is offset 1 ½” in front of dual disc, allowing for cutting of trash and penetrating the soil.
- 7” Row Spacing: All Haybuster drills plant with 7” spacing and each linkage is offset 9 ½” for planting in heavy residue.
- Infinite Seed Rate Adjustment: Easy to set, each box has infinite seed adjustment for accurate seeding rates, no matter what seed you’re planting.
- Down Pressure System: Each linkage has simple downpressure adjustments from 135 lbs. for conventional seeding up to 300 lbs. for no-till application.
- Depth Control Adjustment: Simple, solid depth control adjustment on each linkage.
- Mechanical Drive System: Wide, aggressive lug-type tractor tire drive wheel for positive ground contact to ensure accurate planting.
- Cast Iron Linkages: Built of heavy-duty cast steel, the Haybuster drill linkage is even more durable than ever. The cast steel makes the overall drill even heavier, which is always a positive when reseeding pastures and all no-till applications.
- Three Seed Boxes: The Haybuster drills come standard with two seed boxes with individual metering. The third box (front) is the optional legume box. With the legume box installed, Haybuster drills are capable of planting three different seeds at three different rates.
Optional Features
- Legume Box: Haybuster drills can be equipped with a third seed box designed for accurately feeding and metering small seeds and legumes. Also available with longer hoses, and seed boots for shallow seed placement.
- Native Grass Attachment: Haybuster drills can be equipped with dual seed agitators, large seed hoses, and seed boots for accurately planting light, fluffy bearded seeds such as native grasses.
- Single Bottom Agitators: Prevent bridging of seeds near feed wheels to maintain flow of seeds. It is standard equipment with the Native Grass Kit or can be ordered separately for the rear box.
- Depth Band: Bolted on to the coulter to limit the maximum seeding depth.
- Brackets to mount two barrels for extra weight.
