5100 Grain drill help, need to settle argument!!!!

I have a question concerning the operation of a International 5100 grain drill.

When planting does the Hydraulic cylinder need to be able to "float" or should it be fixed to it can not retract or extend. Two guys here at work say it should be able to float and the drill will create down pressure. I said that the cylinder must be in a fixed position (usually fully retracted or almost retracted) to provide down pressure for the disc openers.

What are the thoughts on this??
 
If it was in float it would plant on top the ground. It needs down pressure to hold the disc in the soil.
 
I hope you don't have a bet on this!!! The cylinder just engages the drive for the drill, the pressure springs on each run supply the pressure on the openers.
 
The cylinder still has to be extended for the drill to work.It holds pressure on the springs.
 
It has to have down pressure, or it will bob along the top of the ground.......not gonna get much of a stand if it is bobbing along the top of the ground.....the down pressure of the hydraulic cylinder is what gives the units down pressure
 
Maybe I misspoke. I have had a 510 since 1972 and when the ram is extended, the drill is out of gear,I must have not understood the problem. In order the increase the down pressure on the 510, the clips on the opener bracket must be changed.
 
Having run both a 510 and 5100 IH's the cylinder cant be in float...Pressure has to be on the springs so I ran the cylinder almost or fully extended depending on the conditions....My cylinder had a stop that you can set...
 
I agree with the others, but I'll throw this into the discussion... If you are seeding a cover crop or some sort of seed that needs to be seeded very shallow (especially in loose soil), then I would think running in float could work to your advantage. But under any other circumstance, the cylinder is needed to put pressure on the rockshaft so the springs can keep the openers at the appropriate depth.
 
Used to have a 510, hooked it to a tractor that didn't hold down pressure well. You had to keep an eye on it as the cylinder would work up and the clutches would kick out. Unless you're in nice soft powder I think you would end up with a lot of unplanted ground if left in float.
 
I always used down pressure.

Alright guys this is getting serious!!!

After reading this thread they are still under the impression that planting in "float" is the way to go.

I feel that if you plant in float that the up pressure from the openers penetrating the ground could cause the cylinder to extend since it is in float and disengage the clutch. They still wont agree that the springs are the adjustment for the down pressure and that the cylinder created the pressure, and the springs adjust how much down pressure is created.

I am running out of ways to explain this to them. It seems so simple to me to see that if planting in float, there will be no down pressure because the resistance from the openers penetrating the ground will not allow any down pressure to be created. The cylinder must be all the way retracted or almost retracted, and "fixed" not in float. It seems to me that the clutch could defiantly disengage if the cylinder is in float and extends outward.

Please please help me explain to them.

Every grain drill I've seen that used a hyd cylinder the cylinder extended to raise disks, retracted to lower disk and one sowed with cylinder retracted to apply down pressure.

Simple solution just don't argue with them and let them drill the way they choose.
