When dumping a bucket, the load is unsupported pas a certain point & pulling on the cylinders. And hydraulic flow is limited so there may not be any pressure on either side if the piston in the cylinder. If seals are worn or leaking the cylinder will suck in air. And you end up with a floppy bucket until the air is purged, until the next dump.
Regen dumps full pressure to both sides of the cylinder. As there is a rod taking up space on one side, the cylinder will overpower the smaller surface area rod end. Instead of going to tank, the excess fluid gets pushed from the rod end to the but end of the cylinder. Pressure is maintained on at least one, if not both cylinder ends so there is no chance for air to get sucked in.
Not an ideal solution, but economical & prevents people from making fun of your floppy bucket.
Makes sense. I remember having lots of problems with air in the cylinders of a 2005 L3400 that i used to run. That would certainly explain it.
