These backhoes are made by Jimna. I bought one (LW-6) from a vendor on Ebay. The unit comes setup to run from remote hydraulics. I wanted to use a PTO pump. This required a larger suction line and the addition of a return line filter. The PTO pump put out 11 gal/min which is too much volume for this backhoe. As a result I had to add a flow control valve.
As received, 4 of the five controls worked backwards even though the decals on the machine indicated differently. Because of the way the control valves are configured, I had to make some adapters so that I could swap the input/output hoses. It was not a simple matter of swapping the hoses on the cylinders. I still had to restrict the flow to the swing cylinders to match the speed of the other functions.
After doing all of this, the machine functions reasonable well. It is more suited to digging holes and rocks rather than trenching because of its limited reach. It is definitely a weekend machine not suitable for commercial use.
