Description

The Topdrop is a practical and reliable topdressing machine designed to maintain smooth and healthy turf surfaces. Over time, sports fields and lawns can become uneven due to regular use. Applying sand or infill helps restore surface balance, improve stability, and support turf performance. The machine attaches easily to a tractor and spreads material evenly across the surface. A hydraulic brush system and adjustable dosing valve allow accurate control over spreading thickness and speed. Balloon tyres ensure smooth movement without damaging the turf. Built with a strong and durable frame, the Topdrop is suitable for both natural grass and artificial turf applications, making it ideal for sports grounds, golf courses, and general turf maintenance.
