Coming up on 50 hrs. on my BX2660. I have put the FEL on & off about 3 times & no problems. Today, because my dealer is picking up the tractor for 50 hr. service work this Monday, I finished up mowing & attempted to attach the FEL. My problem is when I tried to attach the hydraulic hoses, four from the loader to the tractor. I could only get two of them to attach. The middle two would not slide down & click home. It was 96 degrees & an hour of trying everything they still will not click down. Always before I had no trouble with attaching these hoses. What am I doing wrong? I cleared the pressure with the loader stick several times. Still no luck. Help!!!
