Hi all, I need some help. I have a case 1818 skidsteer. The bucket with a load in it struggles to go up at times it won't go up with it empty it will go up and down easy this just started happening I noticed I do have a leak today I power washed all the old crud and after moving it I noticed a puddle of oil in the back (see pictures) two of the lines I don't know how to get to unless I take the motor out the other three I might be able to get to any suggestions on determining which line it may be. These are hard lines where I noticed the oil coming from, but I know leaks can be very tricky and any suggestions or tips
