Counterweight 4200XL excavator

[Dieselchopper]

I have not gotten to it but as time and other projects permit I plan to change counter weight and oil tank. I find it a pain to change the oil as there is no drain and feel that a bigger oil tank would help this machine as well. Was planning to weigh the current counter weight and full oil tank. Then figure out about a 30% to 50% weight increase. and see how well it would work to turn counter weight into large oil tank. Have always thought this hoe needed more counter weight.
