Forestwest 36" Tow Behind Lawn Aerator – Spike Aerator BM11132

The Forestwest BM11132 36" Tow Behind Lawn Aerator is designed for aerating lawns, paddocks and larger grassed areas using a compatible ride-on mower, ATV, quad bike or tractor. Its ground-driven spike system requires no engine, PTO, hydraulics or electrical power, making it a simple and practical solution for regular lawn and property maintenance.

With a 36" / 915mm working width, the BM11132 features 78 heavy-duty 70mm spikes mounted around a durable steel drum. As the aerator is towed across the ground, the spikes penetrate the soil surface to create openings that help air, water and nutrients reach the grass root zone.

The drum can be filled with up to 91 litres of water to increase operating weight and improve spike penetration in firmer ground. Integrated transport wheels make it easier to move the aerator between working areas and help keep the spikes clear of hard surfaces such as driveways and concrete during transport.
