Theirs nothing wrong with them,they are more economical,they have "2 stick"valve body instead of a joystick control,most out of the crate dont have the supports to the rear axles,I believe the Koyker 160 can lift 1500 lbs while the factory clone is a few hundred less,some dealers buy aftermarket loaders in the states so you can fit more in the container,1 loader takes place of a tractor,the loader that comes from Koyker in SD arrive in 10-14 days so they can be ordered on demand,tractor orders take around 60 days give or take
