Just a couple of thoughts about leaving the loader in the float position: If you ever remove the bucket and you're "habit" is to leave the loader in float. Once you knock out that last pin,
the loader will drop, and chances are Murphy will be sure that something with nerves will be under it at the time. (Not that I've ever done that, I just know a guy who has /w3tcompact/icons/wink.gif)
The other reason I can think of is the spool return spring is compressed the whole time the loader is in float and applying pressure to the float detent. Now your not going to wreck anything over a short period of time but why add the extra stress to the system. Probably the best method is to set the loader on the ground and release all pressure with the loader control. The best reason for this is you will avoid any opportunity for the weight of the loader dropping when the kids are goofing around on the machine or you're showing your neighbor (or your wife, ask Rogue about the mower incident) how cool your Kubota is......
