I'm new to this forum and I think there are very knowledgeable folks here. My problem is that my bobcat 773 drives very good and strong but the bucket lift and tilt are very slow and weak. It started gradually after I replaced a hydraulic hose that controlls the right lift cylinder. It is located at the back door on the right side there are 2 short hoses, I replaced 1 of them. Since then it appears the bucket lift slowed and the tilt also slowed.
I have a grapple bucket on there and the claws are also slow and weak. Today I have to rev the engine near wide open to move the bucket up, but its still very slow. At idle the bucket will not move upward are tilt at all. Its full of fluid, the hydraulic pump belt and tensioner are good. Brand new hydraulic filter. All lights are on, ie. seat, seat bar, ect. Emergency brake is off.
It can push against a tree and spin the tires. No warning lights on. Cranks easy, sounds good. No weird noises when I attempt to lift the bucket. Oh, and yes the hose I replaced was with the same size hose.
I didn't find the right solution from the Internet.
