excavator/digger (aditional device for the homemade tractor)

This excavator was designed on demand by my brother. He started to build it without anything, then asked me for help. We designed all parts according to our material possibilities. He ordered some parts like second hand hydraulic cylinders, hoses and control joysticks from the internet. The turret was designed in no ideal way. Now I would design it in another way. But the device worked for almost three years without serious failure. As I remember, my brother had to repair only one pin, hydraulic tank, few bearings on the turret and greasing nipples.
