    Chinese mini dumper stalling in reverse-what to check?

    The tracks are slow enough that I am not being jerked around on it by going full stick F and R, but do you think I am I increasing the odds of damaging the machine by operating it when trying to feather the controls stalls it?

    Chinese mini dumper stalling in reverse-what to check?

    Raising the machine completely off the tracks with the loader and a jack, I see no difference in the stalling behavior. If I try to feather the tracks, machine tends to stall. If I go full stick F or R, it doesn't. I haven't tried loosening the tracks. I think I will try operating the...

    Chinese mini dumper stalling in reverse-what to check?

    Track binding or resistance in the track rollers could play into this, but my number 1 suspect is something hydraulic related. When I first went to the auction yard to load the machine, it had difficulty even lifting the front bucket without tending to stall the engine. It was parked close...

    Chinese mini dumper stalling in reverse-what to check?

    Drove it down a pretty good slope in my yard with a full load of tree debris in the tub without it picking up any speed. Ground speed is like a slow walk. Neither track will feather in reverse w/o stalling. Trying to feather both levers in reverse kills the machine, but going full...

    Chinese mini dumper stalling in reverse-what to check?

    One pump feeds the L track and the other feeds the R track. The valve stack on the left as you are standing on the operator platform controls the L track and the dumper tub cylinder. The valve stack on the right controls the R track and the front bucket cylinder. I haven't tried to run both...

    Chinese mini dumper stalling in reverse-what to check?

    Didn't find anything specific to this kind of dumper machine, but the FB chinese mini forums seems to generally recommend changing the hydraulic oil before operating any of the mini excavators or mini skid steers. Changed out the hydraulic oil with some TSC 46 hydraulic oil. Didn't see any...

    Chinese mini dumper stalling in reverse-what to check?

    I bought this Chinese mini dumper at auction for a little over $1,300 because I wanted an inexpensive track machine to work with in a tight area infested with honey locust thorns. The machine appeared to be unused and still had inventory tags on the rubber tracks when I picked it up from...
