The construction vehicle is provided with an engine, a clutch, a travel device, a work equipment, a drive force setting dial, and a controller that includes: a theoretical value determination unit that determines a theoretical value, for the degree of engagement to make the upper limit value of the drive force equal to a set drive force; an operational state determination unit that determines whether the work equipment is outputting the drive force in a predetermined travel direction; a drive force determination unit that determines whether the drive force is greater than the set drive force; and a degree of engagement reduction unit that, if of operational state determination and of drive force determination are both affirmative, causes the degree of engagement to approach the theoretical value.
