It would be nice if they were that similar. The four wheel drive system is completely different on mine.
The block on mine isn't a priority valve, its a diversion block. I believe full flow goes through the hose, to the loader valve, back down another hose to the block and then on to the rear lift.
Mine has quick connects. All they are is a screw on fitting available at essentially any hydraulic or tractor supply store.
Many of the parts for mine are the same as the North American models, just not everything. The 1500's are supposedly close to the 175's. It helps to build a good relationship with any dealers and parts places that have parts breakdown lists.
