Hi Everyone, I own a Bobcat s205 high flow 09 model it has a 4 in one bucket. I'm having a problem with the tilt hydraulics on the machine.If I go into a pile of gravel or whatever and get a decent load and lift and tilt while going back, the tilt fuction on the bobcat fails.The bucket creeps down, I can tilt up and it will hold but as soon as I stop it goes down. It only happens every other time. I won't get it for a while and then heaps. It seems worse when the oils have warmed up. The rams have recently been serviced. I've had it in at bobcat and they can't find the problem. They replaced all the seals and could not find the problem. It was good this morning for about halve an hour and it started doing it again. Very frustrating.Any help would be much appreciated.
