Crack a fitting at the loader bucket and set a pail under it is one way. The only real way is to change the UTF and put the return lines into a bucket where they return the UTF to the reservoir and open valves until it runs with clean (UTF) but only one out of a million will go to that trouble.
On our BH a drain out and filter change will remove about 33% of the total 22 gallons with the rest in the hoe and FEL cylinders I guess.
I was thinking that be the only was to bleed them.
Where would I find the filter on my loader? Any ideas....
