There is one supplier in Hamilton, but he is three times as expensive as the one in Czechia. the delivery time is the same as from Czechia (one to two months by snail mail parcel, the cheapest way), so I suspect that they order from there and then supply it to you at a premium price.

They do speak English, so conversing via and ordering by email is no problem. Your prices are the ones in small black letters, without 21% VAT (=GST).
From Beno I bought several parts, that regarding quality are definitely not inferior to what you can get from
Zetor Australia; also the Australians are extremely expensive. I bought the brake cylinders complete with pistons and seals, as the price difference is so minimal that not even half an hour of work on them would be justified.
I am in Bombay Hills. Let me know if you will buy from Beno; then maybe you may want to get two Zetor-stickers for me in the same package. My email address is in my details here.
If your steering turns when the wheels are lifted, then your pump runs but you will have a big pressure loss in the system. It might be a hose that developed a small leak because of the sudden pressure peak or a seal or the piston in the cylinder or the internal in the pump itself. What also can be is that somewhere in the line something got heavily blocked, e.g. in the return line, so that the pressure differential of the system is too small to be functional.
