    Default Branson 4720 PTO problem

    I have a seven year old 4720 with 700 hours. I just bought a five foot 3pt tiller and am having problems when engaging the ground. At first it was OK but after about 30 minutes the PTO shaft quit rotating when the tiller is lowered to engage the ground. It also makes a "ratcheting sound internally. I even loosened the clutch on the tiller to allow slippage if I hit something and not slip internally but it made no difference.

    Any ideas?

    First I must say nice photos and I have to compliment the manufacturer on the case and the contents because that's quality manufacturing and machining there.
    What I dont understand is why would hydraulic pressure effect those clutch disc's if they are held in compression by the tension of those springs. To me your photos appear to show a mechanical slip clutch within the shaft of the PTO; so why would hydraulic pump pressure effect those springs? It would seem to me that the amount of torque applied to the shaft via hydro motor dependent on hydro pressure would not effect something mechanical. Someone please help me.
