3-Point Hitch BX 3pt hydro control

[sandyc]

Trying to figure out the proper adjustment for the 3pt hitch hydro control quarter inching bump stops. I’m tired of dropping the implements too fast and see that there are two small stops that are adjustable if you raise the seat. These come into play if you pull the control lever toward you as you either raise or lower the three point. Can’t find any info on these other than they exist but most folks don’t know about them. Any help?

I have a BX25D but I am not sure of the levers you are refer. The is knob below the front of the seat that adjusts the 3ph lowering speed. No set stops on the BX that I am aware of.

I’ll try to send a pic. But if you look down the control lever you’ll see that the lever has a piece of rod welded to it that causes the lever to engage the “bump stops” when you move the lever in either direction. Mine were set at either extreme and as such were not able to be used.

The pic is upside down. Sorry about that

Thanks Jeff. Looks like I’ll do a trial and error thing and make adjustments while lowering my blower. You’d think that would be covered in the ops manual.

Got adjusted ! I can lower the blower very slowly now!

If you are just trying to control the rate of drop, the valve under your seat works the best. Just close it to where you are happy with the dropping speed. You can reach down and adjust the speed for various implements depending on their weight.

It sounds like you are using the quarter inching function to drop it a bit at a time rather than actually slowing the speed of dropping the blower, but maybe that is what you were after - more of controlling travel distance rather than speed?

You are right. I’m trying to slowly lower my blower rather than drop it. I found that by holding the lever against the stop I can get consistent drop speed regardless of where the wheel thing is. If I want full drop speed I can still push the lever away and avoid the stop.

I see you have the 2380 one version newer than mine. Looks like it caught up with the bigger tractors for position control. Nice addition!

Hey orange Dave
I’m not sure it’s considered position control as much as speed control. I believe position control is being able to get the three point down to the same depth by moving the lever to a preset point for the hydro control.

To control the drop speed use the knob between your legs. Works for the MMM and the 3ph.

Here is the page from my operator’s manual.

My first new Kubota was a B3300SU tractor-loader with the 1/4"ing valve.

My second and current Kubota is an L3560 tractor with Position Control.

Both are good. Neither is perfect. Position Control is slightly better.

When performing ground engagement work, such as plowing, box blade grading and disc harrowing, the 1/4"ing valve allowed precise small changes in TPH height superior to Position Control.

Controlling Rotary Cutter height, where returning to precise cutting height after implement lift is desirable, Position Control is superior.

Dave
On the page it shows “slow down” which I think means to engage the bump stop by holding the lever toward you as you move the lever forward. At least that works for me. The stop can be adjusted by loosening the 10mm nut under the seat per my pic.
Thanks for the info.

Using the wheel valve I’ve got it so the blower drops from up to ground in 5-6 seconds. Now the blower just comes to rest instead of slamming into the ground.
