Thanks again for your help on my Power Beyond for my 4300 JD... I did find with all the crap and attachments a power beyond kit with the unit. I had my local JD Service center service the thing and asked about the power beyond hookup. If you look at the photo with the instructions it looks like the pump for the back hoe attachment is actually on the PTO drive at the rear of the tractor. My question is this: Does anybody other than JD make a hydraulic pump for this or is a dealer item only and does the unit actually fit onto the PTO drive shaft????? Any imput will be helpful....Thanks again for your input:
