    Abstract: A wheel loader includes: a mechanical drive unit; a mechanical drive clutch controlling transmission/cutoff of a power in the mechanical drive unit; an HST pump driven by an engine; a hydraulic motor driven by a hydraulic oil delivered from the HST pump; a hydraulic drive unit; a hydraulic drive clutch controlling transmission/cutoff of a power in the hydraulic drive unit; a load detecting unit detecting an amount of a load; a vehicle speed sensor detecting a vehicle speed; a switching controlling unit setting a switching vehicle speed in accordance with the amount of the load; and a vehicle-body controller switching between mechanical drive state and hydraulic drive state based on the switching controlling unit. The switching controlling unit sets the switching vehicle speed at a high-speed side when the load becomes large and at a low-speed side when the load becomes small.
