Disc Mower correct use?

Okay, I know this sounds like a newbie question but here goes: When mowing with a disc mower, should you leave the hydraulic remote in neutral or put it into "float" or "detent" so the mower can follow the terrain? I guess when using older equipment (GEHL DM160) like I have for the past decade the cylinder probably had enough slop to follow terrain. I have since upgraded to Krone AM243S and noticed when going over bumps or rocks in field, the cutter bar would also lift off ground, Leading me to ask this question. Thanks for your help.
 
I have a Krone easy cut 320 and have run mine both ways, in float and not in float. even in float it will not always hug the ground just right especially if you hit gopher mounds and the like.
 
possible. I think mine is set so when it's down it's just pulling on the spring a bit. I think I'm in the second or third hole from the tightest. might need to play with that adjustment. does yours have the double spring or single? my old one had double and it was harder to adjust for different fields but if I remember correctly it too just barely started to pull on the springs when down. can you mow at a down hill angle? I use mine to mow some ditches and if the spring is too tight it wont drop down over the edge all the way. I had to play with mind awhile to get it set where it works the best.

Book for small New Holland I run states to run in float so the cutter bar will follow contours. I normally didn't since the tip would sometimes drag harder and cause it to catch and kick the bar back on rough terrain.

The "bounce" of the cutter bar on this particular mower depends on how high the 3pt is carried in relation to the ground.
 
If I let the hydraulic remote out more it will go downhill but if I leave the remote in neutral and go from flat to mow a side of a slope the cutterbar will stay pretty well level. I have a spring in the middle for the gearbox end and only 1 long spring for the tip. mine pull out quite a bit when laying flat. sounds like I may have to play with it some. thanks for your input
 
Should be in float. RE the springs- your operator manual may show how many pounds of lift should be required when the springs are adjusted properly...ie- literally use a hand held scale to lift the header...ok, you said disc mower, but my NI 5209 discbine had the specs for springs.
 
Mine is a JD 935 moco - a pull type. When I let down the table it is dead weight on the ground. It follows the ground and only gets messed up on terraces. The springs come into play when you lift it. It makes that lift gentle and keeps it from banging around. It has been this way since they delivered and set it up.
