The innovatively designed SV544 is applicable to medium to large soil compaction jobs. Manual Traction Control • High traction capability ensures compaction in both forward and reverse — even on jobs with soft ground, slopes or rough terrains. • Manual traction control allows forward slope and reverse slope operation. Manual Vehicle Speed Control • Selective travel mode (2.5 - 6.2 mph) Vibration System • There are 2 range of vibration, high amplitude and low amplitude. • Reaches target density in fewer roller passes. • Achieves uniform compaction throughout lift thickness. Long Lasting Drum Isolator System • Sakai’s unique drum mounting system extends the life of the drum isolators. • Patented drum vibration isolation system and floating deck keep the operator free from vibration. • Durable, high quality components such as hydraulics, drum and center-pin hitch assure longer life and lower maintenance costs.
