Why is boom rising?

[Jw5875]

Parked the U25 with the bucket on the ground, a few days later
it was a little off of the ground?
I thought gravity would keep it on the ground.

(No I didn't park it upside down)

Maybe heat expansion of the trapped hydraulic fluid raised it.

After several days?,thought fluid would be cooled down.
Thanks for reply.

last fall parked my E32 bobcat with the bucket off ground and house rotated so I could step onto the tracks, now the snow has gone the house has rotated some 40 degrees, bucket still off the ground, the area is flat
