In the operation of a wheel loader, the linkage arrangement that mounts the bucket to the machine must provide components with adequate loading capabilities while maintaining good visibility to the bucket for an operator. The present linkage arrangement includes a tilt lever with a pair of spaced side walls and a tilt link with a pair of spaced side rails. Each spaced side rail of the tilt link has a pair of legs, respectively, which straddle one of the pair of spaced side walls of the tilt lever in a connection which improves visibility while possessing superior strength capabilities.
