Recently had our clutch replaced on our L35, we outsourced the work and ever since the tractor was put back together we have little pressure in the hydraulic lines, as well as some bubbles on the level stick. I was told to check the clamps on the the tube couplers within the hydraulic line. Most if not all lines were replaced and are new, including couplers and fittings. i checked the o ring that is inside the trans and that connection is fine as well. I am at a dead end and need some advice before i have to send this out. The bucket will go up down and curl however you need to give it an abundance of gas to do so and when scooping there is no power, not even enough to pick anything up in the bucket. any new advice would be greatly appreciated.
