6130D Deere

[Taylortractornut]

A friend of mine has a 6130D Deere and he mows roads. The transmission looses prime when mowing and the tractor gets on a left handed slope. After a few minutes off and in neutral it will go again. Will mow all day with the right side down hill. Deere dealer won’t even look at it so he called me. The transmission fluid it full as well. I’m wondering if a pick up tube may have a crack and getting air when the left side is down hill
