The new, narrower (600 mm / 23.6 in) Ammann ARR 1575-2 Trench Roller fits into tighter spaces – and moves more freely, too. Extension kits can increase the working width to 860 mm / 33.9 in on more open jobsites. The oscillating steering joint’s unique design ensures uniform weight distribution between both axles, providing permanent and consistent ground contact on uneven terrain.
