- The Speedresser 24H is a 2.4m wide drop-spreader designed to handle all top dressing material. The 4 flotation tyres minimise the risk of turf damage and compaction. The Speedresser 24H requires a tractor of at least 75Hp and is PTO driven, via a heavy duty transmission to an agitator and twin rollers. The twin rollers are now hydraulically adjustable against a pre-set stop to alter spreading rate applications. The high work rate enables the spreading of top dressings up to depths of 2mm – 75mm in one pass.
