2305: 3PH Float Position

RichO said:

Question: Is the far forward position for the 3PH control considered the "float" position for the 3PH on a JD 2305? Is it safe to utilize an implement (rear blade) in this position vs. the mid-position?

Pulling the handle towards the rear of the tractor lifts the implement. I assume the middle position locks the implement from further downward travel (but it will still allow the implement to float up if it hits something). The furthest forward position allows the implement to lower.

Thanks,

Rich,

The 3PH is all float. On your 2305 you have up, down, and in-between settings. You can lock the 3PH using the "rate of drop" control or slow or speed up the rate, but 3PH implements automatically follow ground contours.

JDFANATIC,

First, thanks for the quick reply.

Second, the "rate of drop" control is only for drop from what I can tell (Hence the name). Is there anyway to slow down the "rate of up"? Fine tuning a blade would be easier if the up position was controllable.

How i was reading his reply was it speeds up or slows down the rate of drop.. Not controlling the rate of up..

Rich,

If you look at 3PH rakes you will see gauge wheel options. They often cost as much as the rakes, but without them, you get a washboarding effect. I think this is what you are experiencing.

Thanks, I agree gauge wheels help any leveling operation (ala road grader).

Another reason for the question is for moving trailers. If the 3PH is always in float (at least for the up direction), then if a trailer load shifts and pulls the tongue up, that could create a significant hazard for the operator.

While the mid-position will lock the 3PH from going any lower, it does not sound like you can lock the 3ph from going any higher in any configuration. Even the rate of drop knob only affects the downward drop rate.

Thanks.

Hi

True if there is no down pressure than the rate of drop control will not work on the up speed. The exception would be on tractors likethe 2520 that have down pressure, I assume the rate of drop control would work in both directions in that case but it would depend on how the control is connected.
I have a receiver on my ballast box and I never considered what would happen if there was a upwards force on the hitch. Thanks for the heads up!:fing32: although in my case there would have to be 600lbs of upwards force to lift the ballast box.

JDBrian,

Reciever hitch on the ballast box is a good idea. My Simplicity Sunstar extended the hitch on the ballast box so you never really had to take the ballast box off. Did you weld it on or did you drill and bolt it on? The JD ballast box doesn't have any mounting points on it from my recollection. I filled my ballast box with bricks so it is easy to unload them and reload them.

Hi RichO

I posted a thread about the hitch last year. Here is the link

Have a look.

When I think about it the hitch will be near or at the top of it's travel when in use so there wouldnT be too much trouble if it lifted up under load.

Cheers
