Question about Draft/Position control on new DK45S

[8NAcres]

Just had my new-to-me DK45S delivered last Saturday and gave it a heck of a workout bringing down an old barn. I needed to hook my trailer to it and I like to use the 3 point hitch with a drawbar attached to connect. When I got the tractor, both the position and draft controls were pulled all the way back and the 3 point was raised. I lowered the position control lever but the 3 point arms did not respond. If I lowered the draft control lever the arms would lower, but pulling back on the Position control lever would not make them raise. It appears only the Draft control lever affects the 3 point arms at this point.

I could not find anything on the owners manual except in the Troubleshooting section that is the hydraulics do not lower to - Check the hydraulic adjusting grip. (whatever that is). Is there something simple at play here that is not obvious to this new Kioti owner, or do I need to call the seller to discuss?

Thanks.

If the remote lever is in the on position the 3 point will sometimes not respond until you switch it to the off position Also it is not good to have the remote in the on position with nothing hooked up to the remote.

Turn your remote in neutral and draft all the way forward and make sure the 3 point adjuster knob is locked tight. the knob is between your legs by the floor mat. Then move your 3 point lever.

For normal 3pt operation, Place draft control (yellow knob) all the way forward. Adjust the 3pt rate of descent knob so that the load on the 3pt will not hit the ground too fast or too slow to suit you. This knob is below the seat near the floor in the center, not to be confused with the seat adjustment. This knob if turned all the way clockwise will restrict the flow totally and not allow the load on the 3pt to go down at all. It will be locked. Turn it counterclockwise to allow the fluid to flow and the load to fall by gravity. To raise the load on the 3pt, use the position control lever (red knob) towards the back of the tractor to raise, and toward the front of the tractor to lower. Again the speed of lowering only is controlled by gravity (the weight of the load) AND the flow rate you have dialed in on the rate descent knob under the seat, near the floor.

I hope this helps.

There are four things here.

First, the small round shaft (with a spherical knob on the end) controls hydraulic flow to the remote quick-disconnects at the back. The fore and aft positions direct flow to one or the other QDs. But with nothing connected at the QDs, this "dead heads" the flow which puts a strain on the hydraulic pump. Prolonged operation with a deadheaded load will damage the hydraulic pump; you don't want to do that. When the remote is activated (fore or aft) it steals hydraulic power from the three-point hitch. Bottom line: keep that lever centered if you aren't using remote hydraulics and especially beware of it getting accidentally put in the detent position.

Second, there is a knob between your feet that controls the lowering speed of the three point hitch. The hitch lowers by gravity only; there is no hydraulic down force. If this knob is screwed in too far (which is easy to do by accident) the hitch will not lower.

Third is the draft control. You want this full forward unless you are plowing or using ground-engaging attachments..

Finally, the position control. When the draft control is full forward, this lever controls the up-down position of the three point hitch.

Back to the draft control. This control is intended for use with ground-engaging attachments, like a plow. It works in conjunction with the different top-link holes on the tractor. When the attachment meets enough resistance, the draft system raises the attachment to allow the tractor to continue moving forward. The draft lever (in conjunction with top link hole selection) sets the sensitivity for raising the attachment. The further the draft control is pulled back, less force will raise the attachment.

I just saw James' reply. On my DK45s, both draft and position levers are red but otherwise clearly marked.

Out of these 3 reply's he should get something going!!

I was just going by mine, and I figured all the draft controls were yellow, but apparently not.. Oh well, it should say on it somewhere.

On mine the draft lever is the one that is the nearest to the seat the the position control is the furthermost away from the seat.

Not questioning ANY replies here - just posting an obvious point. The valve by the floor shows it is to change the speed of the 3 point lowering. I was able to bring the arms down using the draft lever (so the arms are now down), the draft lever is now at the bottom of the selector, and the 3 point arms did not respond to the position control lever at this point. Since the valve by the floor only affects the speed to LOWER the arms, I can't see how it would keep it from RAISING the arms(?) Also, since the draft lever was at the bottom position, according to your replies that should make the Position lever take control if I am reading your replies correctly - and this did not happen.

Am I missing something?

Also - the rear hydraulic controls appeared to me to be in the middle of the selector range.

We were thinking it might of been fully closed as not being able to go down at all.

Now with the draft lever down try to move the 3 point lever to the up position.

Murph - I did this. Once the arms lowered using the draft control lever (they will move up and down all day long with the draft control lever), and with the draft control lever in the DOWN position - the position control lever still did not move the 3 point arms at any point along the range selector slot.

Then it is broke. If all of the valves in front of the position control are centered. (loader valve, and either of the 1 or 2 remote valves) then there is a problem. Are you sure the 1 or 2 remote valves you may have are not stuck in the detent position? Lets start with either a picture or tell us how many remote valves you have.

8N: Our descriptions, above, tell how it is supposed to work. Based of your description, it sounds like the position control lever isn't doing anything. The position lever is supposed to be clamped to an inside shaft that goes into the 3-point hydraulics under the seat. Here's what the control assembly looks like: 3-point controls.

If you are lucky, maybe just the screw (#23) is lose allowing the position control lever (#21) to slip on the shaft. You should be able to see this from the back of the tractor behind the rubber flap on the right side.

Tractor is out at my land (I do not live there - just getting it ready to retire and move there) so I do not have physical access to it right now - but I can say I have a small bar at the rear next to the right 3 point top link that looks like it is to control the 3 point arms when you are at the rear hooking up an implement. If I move this bar, I can look through the back window of the cab and see the Position control lever moving up and down as well.

Next time I go out I will double check the remote hydraulics lever and play around with the small knob by the floor. Also, check the lever to make sure it has not slipped on the shaft. If all appears fine, I guess I will need to contact the seller.

Thanks all for the info and suggestions.

8N: that lever on the back is linked directly to the 3-point position lever to allow you to raise or lower the three-point arms from the back, making it easier to attach implements. I don't have the cab model but this is how mine looks:


Now if you lift that rubber flap, you can see the linkages, In this shot the position lever is in the"up" position and you can separate linkages from the cabin position lever and the aft position lever which attach via small ball joints to the lever on the shaft.


Now here's a final shot with the position lever down. Sorry about the sharpness, I guess I moved the camera. The main thing here is the lock screw that is supposed to lock the position lever to the shaft. This is what I'd check. Maybe it's just lose or missing.


Based on your description, the position lever isn't doing anything. So maybe that outboard lever is not turning the shaft. Note that there is a procedure to lock it to the shaft at the proper orientation. If this isn't the case, it's more serious; either the shaft is broken or the other end of the shaft (inside the 3-point hydraulic unit) has come undone. Did you get any sort of warranty?

I would add that a circlip on that shaft keeps the position control arm from sliding off, even if it were lose. Also, there are flats ground into the end of the shaft (beyond the circlip) where you should be able to feel if the shaft is turning with the position control or not.

ADDED Let me also add that the bell-cranks on the shafts don't quite look like the simple "arms" shown in the parts manual or the service manual page posted above. I decided we already have too many things called arms so I'll refer to those draft and position brackets on the shaft as bell-cranks.

Scott - I will investigate this when I go out this weekend. This is a used tractor so it is pretty much "as is", but the sellers are a small mom & pop shop that said they would take care of me if I found anything wrong when they delivered it. I sure hope I don't have to test this if it is anything other than simple adjustment.

 

[8NAcres]

UPDATE - I went out to the property this past weekend and was able to take all of your advice and put it to use. Thanks for the info, it ended up being the small floppy knob by the floor was turned all the way one direction to the stop. I unscrewed it just a few turns and the lift started working in position control mode then. Not sure WHY the knob that controls the speed the three point drops keeps it from going up but it sure does.

Thanks all for all the help.

Great! Glad it was something simple and cheap. That knob between your feed tends to get moved from time to time as your boots brush against it. So it's a good first thing to check. I was not aware that this knob could disable position control while the draft function still worked. Learn something new every day.
