Abstract: A work vehicle includes a speed limit calculation portion, a speed determination portion, an adjustment portion, and a boom speed determination portion. The speed limit calculation portion calculates a speed limit for limiting a speed of a cutting edge of a bucket. The speed determination portion determines whether or not a speed of raising the boom has been lowered when an amount of operation of an arm is smaller than a prescribed amount. The adjustment portion delays speed change to the speed limit. The boom speed determination portion determines a target speed of the boom based on the speed limit after delay by the adjustment portion when it is determined that the speed of raising the boom has been lowered, and determines a target speed of the boom based on the speed limit calculated when it is not determined that the speed of raising the boom has been lowered.
