Billy Goat AET Series 48/72" Tow Behind Aerator, Tine Disengagement Bar and Footpad

The Billy Goat AET Series 48/72" Tow Behind Aerator is a modular core aerator designed for professional landscapers, groundskeepers, property maintenance crews, and owners of large residential or commercial properties. Built for use with a riding mower or tractor, the standard 48 in (121.9 cm) unit can be configured down to 24 in (61.0 cm) or expanded to 72 in (182.9 cm) with an optional expansion kit. Its durable coring tines penetrate up to 3 in (7.6 cm) deep, while the tine disengagement bar, footpad, and optional water ballast jugs help operators maintain productivity across large turf areas.

KEY FEATURES

• TINE DISENGAGEMENT BAR AND FOOTPAD: The tine disengagement bar and footpad provide a convenient way to raise the tine assembly when aeration is not required. This makes it easier to reposition the aerator, cross paved surfaces, and prepare the machine for transport without dragging the tines.
• PILLOW BLOCK BEARINGS: Durable pillow block bearings support the tine assembly during operation and help maintain smooth rotation under demanding working conditions. Their accessible design also supports routine inspection and maintenance for professional crews.
• MODULAR 24/48/72 IN (61.0/121.9/182.9 CM) AERATION WIDTH: The standard 48 in (121.9 cm) aerator consists of modular sections that can be configured down to 24 in (61.0 cm). An optional expansion kit increases the working width to 72 in (182.9 cm), allowing operators to adapt the machine to different property sizes and access requirements.
• 48 STANDARD CORING TINES: The standard 48 in (121.9 cm) configuration features 48 coring tines arranged across two modular sections. Each 24 in (61.0 cm) section has four tine stars with six tines per star, providing consistent soil-core extraction across the working width.
• UP TO 3 IN (7.6 CM) CORE DEPTH: The coring tines are designed to penetrate up to 3 in (7.6 cm) deep under suitable soil conditions. Removing soil cores helps relieve compaction and improves the movement of air, water, and nutrients into the root zone.
• OPTIONAL WATER BALLAST SYSTEM: Optional polyethylene water jugs add approximately 40 lb (18.1 kg) each when filled with 5 US gal (18.9 L) of water. Positioned directly over the tines, the jugs provide additional downward weight to help improve penetration without requiring bulky steel ballast weights.
• INTERCHANGEABLE MODULAR COMPONENTS: The modular construction allows the aerator to be reconfigured for different working widths using compatible components. This flexibility helps contractors accommodate smaller areas while retaining the option to expand coverage for larger properties.
• TOW-BEHIND OPERATION: The AET Series is designed to be pulled by a riding mower or tractor with a minimum engine rating of 15 HP. This allows operators to aerate extensive turf areas using existing grounds-maintenance equipment rather than operating a separate walk-behind machine.
• PINNED TOW BAR: A 5/8 in (15.9 mm) pinned tow bar provides a straightforward connection to compatible towing equipment. The simple hitch arrangement makes the aerator convenient to attach and remove when switching between grounds-maintenance tasks.
• 10 IN (25.4 CM) PNEUMATIC WHEELS: Pneumatic wheels support the aerator during transportation and when the tines are disengaged. Their design helps operators move the machine between work areas and maneuver it around larger properties.

APPLICATIONS / USE CASES

• LARGE RESIDENTIAL PROPERTY AERATION: The standard 48 in (121.9 cm) working width allows property owners and contractors to cover large lawns efficiently. Tow-behind operation makes it practical to aerate extensive turf areas using a compatible riding mower or tractor.
• COMMERCIAL GROUNDS MAINTENANCE: Groundskeepers can use the AET Series to maintain commercial properties, institutional lawns, and landscaped common areas. Its modular design provides the flexibility to adjust the working width to suit different locations.
• SOIL COMPACTION RELIEF: The coring tines remove soil plugs to create openings in compacted turf. Core depths of up to 3 in (7.6 cm) help improve access to air, water, and nutrients as part of a regular turf-maintenance program.
• SPORTS FIELDS AND RECREATIONAL TURF: The wide aeration path is useful for maintaining large, open turf areas where efficient coverage is important. Optional water ballast can provide additional downward weight when soil conditions require greater penetration.
• OVERSEEDING AND TURF RENOVATION: Core aeration creates openings that can improve seed-to-soil contact during overseeding projects. The modular working width allows operators to adapt the aerator to different renovation areas.
• PROFESSIONAL LANDSCAPING SERVICES: Contractors can configure the aerator for 24 in (61.0 cm), 48 in (121.9 cm), or 72 in (182.9 cm) working widths, depending on the installed modules and accessories. This versatility helps crews accommodate different property sizes with one equipment platform.
• SEASONAL PROPERTY MAINTENANCE: The AET Series is suitable for spring and fall aeration programs on large residential and commercial lawns. Its tow-behind design allows operators to combine aeration with their existing tractor or riding mower equipment.

WHAT'S INCLUDED

• One Billy Goat AET Series tow-behind aerator in the standard 48 in (121.9 cm) configuration
• Two modular 24 in (61.0 cm) aeration sections
• 48 standard coring tines
• Tine disengagement bar and footpad
• Pillow block bearings
• 5/8 in (15.9 mm) pinned tow bar
• 10 in (25.4 cm) pneumatic wheels

The towing mower or tractor, water ballast jugs, and 72 in (182.9 cm) expansion kit are not included with the standard configuration unless otherwise specified.

OPTIONAL ACCESSORIES

• INDIVIDUAL POLY JUG – 40 LB (18.1 KG) WHEN FILLED WITH 5 US GAL (18.9 L) OF WATER: This individual polyethylene jug provides optional water ballast for applications requiring additional machine weight. When filled, it adds approximately 40 lb (18.1 kg) directly over the tines to help improve soil penetration, and it can be drained to reduce weight for transport.
• AET EXPANSION KIT – EXPANDS AET48 TO 72 IN (182.9 CM) WIDTH: The optional AET expansion kit, part number 361273, increases the standard aerator's working width from 48 in (121.9 cm) to 72 in (182.9 cm). This additional coverage helps professional crews aerate larger properties with fewer passes and greater efficiency.
