Agricultural machine, e.g. mini tractor

摘要

The machine has a boom (10) which can be mounted by a lockable coupling device on the machine. It has at least one bearing point for the cultivator tool (32). The coupling device may comprise a holder (11) on the cultivator tool, and a coupling rod on the boom. The holder may have two parallel spaced side plates (13) with each plate having two superposed sockets (30,31) for two fixed bolts (14,15) of the coupling rod. The coupling rod can be a lift rod, e.g. parallel guide rod linkage. After unlocking the rotary bolts (27) on the fixed bolt of the rod linkage the boom can be removed from the holder.
