So I was messing around with the box blade and my brand new hydraulic top link and noticed the blade was acting funny. Then I noticed the check valve assembly and one of the hard lines was making contact with the tractor frame when I was full up. So now I need to replace the hard lines and fittings. I’m not sure what went wrong…looked fine when I put it on. I had it in the middle of the three holes on the tractor side and the only hole on the blade. Do you guys mount them with the check valve and hoses closest to the tractor or the implement? Should I be using a different hole on the tractor side? It’s the length the manufacturer recommends. Thanks for any help. I feel like an idiot.
