I beleive the 225 hydraulic excavator stopped being built in 1991.
The new version, would be a 325... but it is over twice the weight, and quite a bit more horsepower.
The 322 would be closer to the horsepower of the 225, but the weight is still about twice that of the 225.
There are also a large number of boom stick configurations available on any excavator, and the configuration will will influence the breakout force.
As a reference the 322C with a standard boom and stick would have 151 kN (33,930 lbs) of curl force and 116 kN (26,070 lbs) of crowd force.
For the actual forces on the 225, you would need a spec sheet from that unit, or an older handook, from the late 80's early 90's.
