8930 tractor air seeder return line

[caseman]

I hooked my valmar up to the tractor and oil came out the transmission
breather which is located up high behind the rear lights.

In the operator manual it shows the breather on top of the trans. On this tractor the return line is tied in to the line which goes to the breather.

Should I just not use the return line or try to fix this problem??

Thanks.

Using a return line helps keep the hyd. oil cooler, which increases longevity of oil and tractor parts. The factory installed return lines on our Magnum tractors enter into the top/outer corner of hyd. valve bank. Hope this info helps.
