An overload and overfill protection system for a round baler includes a selectively engageable drive mechanism located between a rotary input member of the baler and an input driven member, such as a sprocket, which drives a pickup mechanism forming a part of the round baler. Fast compression of variable length symbols may include receiving a variable length symbol with one or more tokens; combining the one or more tokens in the variable length symbol to form a token combination; and determining a bit representation of the token combination in correspondence to a probability threshold associated with the token combination. The new variety was created by artificial pollination at Hy\xe8res, France. The forwarded bandwidth estimates are compared to a sending bandwidth. Contention is indicated if the currently stored count value and the incoming updating count value are the same.
