• 4WD axle is pendulum mounted and permanently sealed and
lubricated, requiring no daily maintenance. Also features
double-acting steering cylinder with 52° steering angle for
increased maneuverability. Oscillation 10° each direction
from centerline.
Brakes
Features:
• Brakes meet the following standards: SAE J1473 and
ISO 3450 requirements.
• Boosted, self-adjusting, completely enclosed and sealed
outboard brakes allow easier servicing.
