Abstract
The present invention provides an agricultural machine which allows arrangement of a hydrogen tank and a fuel cell at optimal positions while appropriately protecting the hydrogen tank and the fuel cell. The present invention comprises: a vehicle body (5); a hydrogen tank (21) that accommodates hydrogen; a fuel cell (22) that generates power by using hydrogen supplied from the hydrogen tank (21); a first bonnet (3) that is disposed on the vehicle body (5) and accommodates the hydrogen tank (21); and a second bonnet (4) that is disposed on the vehicle body (5) and accommodates the fuel cell (22). The first bonnet (3) and the second bonnet (4) are aligned in the front-rear direction of the vehicle body (5).
