Can you tell me if in these photos your are using a stock Kubota top link. Also can you give me the length of the top link pictured here.
I just purchased a BX25 and a RB1560.
The angled blade is very tough to use without top and tilt. It can be done with skid shoes as well. The heavier the blade the better as they often when the resistance is high just ride over heavier objects.
