Billy Goat OS550 Series 25 LB Capacity Overseeder, Honda and Vanguard Engine, Auto Drop System

The Billy Goat OS550 Series 25 LB Capacity Overseeder is a commercial walk-behind lawn overseeder designed for landscaping contractors, lawn-care professionals, rental businesses, and property maintenance crews. Powered by a Vanguard engine, it combines a 20 in (50.8 cm) slicing width, a 25 lb (11.3 kg) front-mounted seed box, and an automatic seed-drop system to make lawn overseeding more efficient. Its heavy-duty bale controls both blade engagement and seed release, helping operators conserve seed while achieving consistent coverage on residential and commercial turf.

KEY FEATURES

• FOLD-N-GO™ NO-TOOL, NO-BOLT FOLDABLE HANDLES: The folding handle design allows operators to prepare the overseeder for transportation or storage without removing bolts or using tools. This saves time between jobs and helps landscaping crews make better use of space in trailers, service vehicles, and equipment storage areas.
• INFINITE HEAVY-DUTY DEPTH ADJUSTMENT: The adjustable slicing depth ranges from 0.125 in (0.3 cm) to 0.5 in (1.3 cm), allowing operators to select the appropriate setting for different turf conditions. Continuous adjustment provides precise control over seedbed preparation and helps achieve consistent seed placement.
• AUTO DROP™ SYSTEM: Billy Goat's exclusive Auto Drop™ system automatically starts and stops seed release with bale engagement. By coordinating seed distribution with blade operation, it helps reduce wasted seed during turns, stops, and repositioning.
• 25 LB (11.3 KG) FRONT-MOUNTED POLY SEED BOX: The durable polyethylene seed box holds up to 25 lb (11.3 kg) of seed and resists rust and denting. Its front-mounted design keeps seed accessible, while instructions located beneath the lid help operators select the appropriate seed-drop rate.
• HEAVY-DUTY WHEELS: Durable wheels support the overseeder during regular commercial and rental use. They help operators maneuver the machine across lawns and transport it between work areas.
• DUAL-FUNCTION BALE CONTROL: The heavy-duty bale operates both the slicing blades and the automatic seed-release system. This coordinated control simplifies operation and helps prevent seed from being discharged when the blades are disengaged.
• 20 IN (50.8 CM) SLICING WIDTH: The slicing system prepares a consistent seedbed across a 20 in (50.8 cm) working width. This helps operators cover residential and commercial lawns efficiently while improving seed-to-soil contact.
• UP TO 13,200 SQ FT/HR (1,226 M²/HR) PRODUCTIVITY: The overseeder is rated to cover up to 13,200 sq ft/hr (1,226 m²/hr), making it suitable for routine lawn renovation and seasonal overseeding. Its automatic seed-drop system helps maintain efficient operation by reducing unnecessary seed discharge.
• HONDA ENGINE: The Honda-powered OS552H offers an alternative engine configuration for professional lawn-care contractors, property maintenance crews, and equipment rental businesses. It features a 20 in (50.8 cm) slicing width, a 25 lb (11.3 kg) front-mounted seed box, and the Auto Drop™ system, which automatically coordinates seed release with blade engagement to help reduce seed waste.
• VANGUARD ENGINE: The OS553V is powered by a 169 cc (10.3 cu in) Vanguard engine with recoil start. This engine configuration supports dependable operation for professional lawn-care and equipment rental applications.
• CONVENIENT SEED-DROP INSTRUCTIONS: Seed-drop guidance is mounted beneath the seed-box lid for quick reference during setup. This helps operators select an appropriate application rate without relying entirely on guesswork.

APPLICATIONS / USE CASES

• RESIDENTIAL LAWN OVERSEEDING: The OS553V is designed to introduce new grass seed into established residential lawns. Its adjustable slicing depth and automatic seed-drop system help operators prepare the turf and distribute seed in a coordinated pass.
• PROFESSIONAL LAWN RENOVATION: Landscaping contractors can use the overseeder to improve thin, worn, or patchy lawns. The slicing blades create openings in the soil that improve seed-to-soil contact during renovation projects.
• COMMERCIAL PROPERTY MAINTENANCE: The 20 in (50.8 cm) slicing width and productivity of up to 13,200 sq ft/hr (1,226 m²/hr) make the machine suitable for maintaining commercial lawns and landscaped properties. Its folding handle also simplifies transportation between job sites.
• SEASONAL TURF REJUVENATION: The overseeder is suitable for spring and fall lawn-improvement programs where new seed must be introduced into existing turf. Adjustable depth settings allow operators to adapt seedbed preparation to different lawn conditions.
• PATCHY AND THINNING TURF: The slicing system creates openings that help grass seed reach the soil beneath existing vegetation. The automatic seed-drop system helps conserve seed when working around irregular lawn areas and landscape obstacles.
• EQUIPMENT RENTAL BUSINESSES: The dual-function bale, onboard seed-rate instructions, and no-tool folding handles make the overseeder practical for rental applications. These features simplify customer operation, equipment transport, and preparation between rentals.

FREQUENTLY ASKED QUESTIONS (FAQ)

1. How does the Billy Goat Auto Drop™ system work?

The system automatically starts and stops seed release when the operator engages or disengages the bale. Because the bale also controls blade engagement, seed is distributed while the slicing system is operating, helping reduce waste during turns and stops.

2. What is the difference between the OS552H and OS553V?

The OS552H uses a Honda engine, while the OS553V uses a 169 cc (10.3 cu in) Vanguard engine. Both models share the same slicing width, seed-box capacity, depth-adjustment range, and automatic seed-drop system.

3. How much seed can the overseeder hold?

The front-mounted polyethylene seed box holds up to 25 lb (11.3 kg) of seed. Its rust-resistant construction is designed for regular outdoor use, and seed-rate instructions are located beneath the lid.

4. How deep can the OS550 Series slice into the soil?

The slicing depth is continuously adjustable from 0.125 in (0.3 cm) to 0.5 in (1.3 cm). Operators can select the appropriate setting based on turf conditions and the seedbed preparation required.

5. Is the Billy Goat OS553V easy to transport and store?

Yes. The Fold-N-Go™ handles fold without tools or bolt removal, reducing the space needed for transportation and storage. This is especially useful for landscaping contractors and rental businesses moving equipment between properties.
