Abstract: A utility vehicle having a front loader bucket includes shaped towers and shaped boom arms connected to the towers, and a sloped hood and a shaped fuel tank which all increase the operator's view of the bucket, wheels, axle and ground for close control of the utility vehicle bucket with respect to external structures and surfaces. The towers extend substantially vertically from the utility vehicle chassis to a mid-location wherein the towers are offset inwardly to top ends thereof. The boom arms are connected to the top ends of the towers, extend forwardly, and are offset outwardly to a mid-location of the boom arms wherein the boom arms then extend forwardly to be connected to the bucket. Hydraulic cylinders connect the boom arms to the towers between mid-locations of the towers and mid-locations of the boom arms. A fuel tank overlies a driver-facing surface of the engine compartment and towers and includes gaps in the fuel tank to allow visibility of the front axle and ground beneath the utility vehicle. The hood is sharply declined from the fuel tank toward the bucket such that the operator can view a top edge of the bucket, when the bucket is in its lowered position.
