I have some updates on this Chinese mini-excavator thread:
A local contractor, Jason, just imported 3 of the latest 1-ton minis from Xiniu, aka Shandong Landworld. They seem to want to use the name Rhinoceros, which is the English translation of the Mandarin word Xiniu. They will still put any name on them that you request.
He brought one by my place for me to test out. The improvements include installation of a Kubota D722 EPA-certified diesel engine, check valves on the boom and dipper circuits, hydraulic thumb, improved hydraulic filtration, 4-post ROPS, and a swing boom. There are also gauges to monitor engine oil temp and hydraulic oil temp. A Lovejoy-type coupler is used on the hydraulic pump instead of a rigid spline coupler.
Jason requested, specified, or designed most of these improvements. I suggested the improved pump coupling when I bought my XN08 from Xiniu 3 years ago.
