Hi, I have a Davis Model 185 Backhoe that I would like to convert over to run off my open system hydraulics from my tractor. The backhoe currently runs off a pto pump and has it's own small 5 gallon hydraulic reserve tank. The reason for the conversion is due to the difficulty in hooking the backhoe to my tractor and that the small 5 gallon hydraulic reserve tank gets extremely hot. My tractor has 16.1 GPM flow at 2755 psi. I hooked up the suppply and return lines from the backhoe to one set of remotes and used a bungee cord to hold the line open for hydraulic flow. The first time I did this I blew a small hydraulic bypass line. The tractor was idiling when this happened. I then made the repair to the line. I then bungeed the line down again to allow hydraulic fluid to flow. The lines on the dipper, swing arms, bucket,etc... all acted if they had fluid flowing to them under pressure. I tried to operate the backhoe and none of the controls would work. Any suggestions on what might be going wrong? I checked my feed and return lines for direction of flow and they are correct.
Thanks!!
Thanks!!
