High and ultra-High clearance Tower
The 4 or 4.90 m under truss rods raised tower is perfect for high-growing crops like sugar canes, arboriculture, etc. and to pass over obstacles like buildings, machines, etc. It also allows an under span ground clearance on uneven parcels. Used on the final tower, it can enable to lift an overhang to pass over the obstacles.
Wheels
Rims in galvanized steel fitted with valve protection.
