The link assembly includes a pair of first links each having a rear end pivoted to the vehicle and a pair of second links each having a front end pivoted to the deck of the mower, the front end of each first link being inflexibly and removably fixed to the rear end of each second link by a locking pin. A spring is provided between each first link and the vehicle. The cutter unit can be attached to and removed from the vehicle without removing the spring.
