Loader comes with the smaller pump (as shown in the webshop), a copy of the original german Leimbach setup.
As with tools, hydraulics and many sorts of mechanical equipment..quality costs...'If you don't got a rich daddy..: get one..
Or save some more months and buy stuff that works out of the box.
The loader looks nice, and runs quick on the videoes I've seen. Just use it as long as the hydraulics last, then upgrade to better components as the original stuff starts leaking/break. That pump setup looks like the same as many in my area use for their Tamiya/Carson semi dumpers, converted from mechanical to hydraulic. Seams to be working alright and looks pretty leakage free.
