[QUOTE="onehunter, post: 113819, member: 19493"] Thanks for the feedback. With the boom fully raised or the bucket fully tilted, and held in those positions, the engine rpms dropped by around 100. When I shut off the machine, with the boom elevated, it starts to slowly drop almost immediately. As far as picking up heavy loads, I can raise a full bucket of sand at idle. The hydraulics seem very strong. You mentioned resealing the cylinders, if the seals are bad, wouldn't that mean they should leak? My machine is nice and dry with no leaks anywhere. Or can a cylinder not leak, but also not hold pressure? Thanks Al [/QUOTE]
