2305 vs 2520 Rockshaft Control

[ADin]

Can someone provide an explanation of the difference/deficiency of the 2305 rockshaft control vs. the "position control" on the 2520? The dealer made it sound as if the only options with the 2305 were full up, full down, or float. It seems like that could be a big problem with a lot of rear implements. Is this understanding correct and if so how does this hinder usage of realworld attachments common on these machines (BB, scraper blades, etc). Additionally, does "position control" support the float function as well?

On the 2305, think of the lift control as a "faucet" for the hydraulic control, similar to the the water faucet in your house. You can open it (back), permitting hyrdraulic flow in one one direction (for lift), open it the opposite direction(forward), to permit hydraulic bleed (for lower and float), or you can return the lever to center position to stop all flow, therby locking the arms in the current position, whatever that may be. On a position control system, there is normally a resettable stop or at least some form of scale to indicate a relative position within the full scale of travel. This allows the operator to control arm travel quickly and easily from the seat as well as adjust the implement operating parameters as the need dictates. One common use for position control is to regulate depth on a standard moldboard plow. This type of system is more complicated and therefore more expensive, hence it's not on our 2305's Hopefully, this explanation helps!!

I thought you explained that real well UNTIL you added the line
""One common use for position control is to regulate depth on a standard moldboard plow."" /forums/images/graemlins/wink.gif To me that would be the least common use for position control, and the old Fergies, 2N and 9N Fords were moldboard plow tractors without position control - only draft control.

A common use of position control would be rotary cutting, blading, hooking up attachments with a quick hitch, using a carry-all, box blade, PHD, etc. Most attachments other than moldboard plow would work best with position control, at least as I see it. /forums/images/graemlins/wink.gif Sorry for the contradiction.

So then it sound like any variable positioning is actually possible, but simply more "fuss" to catch it at exactly the right point (going up or down) to lock it in down. Makes sense then that the "rate of flow" adjustment is then used to trade off adjustment speed versus sensitivity.

Beenthere,
No problem on the contradiction, I was only speaking from a point of personal experience, the last experience being from the 1970's. I spent many hours plowing and discing at that time, perhaps I should have stated "my most common use". Anyway, thanks for the primer; I appreciate the information.

It would be great to have such a system on the 2210/2305 series, wouldn't it? Even if we didn't use it all the time, it would come in real handy; not having to try to stop the lift or fall at exactly the right time. Take care!!
