    Default Limited 3PH lowering capability, tall tractor or..

    kubota Grand L-4610HSTC with hydraulic TnT Of course, standard Cat I 3PH (standard??)

    I tried to help a neighbor with a trench. He had a Cat I subsoiler which worked great on his tractor but his tractor was out of service. So... I hitched up and tried to scratch a line in the dirt. I couldn't get my 3PH low enough to the ground to do any good.

    *^*^*^*^*^ Time passes...

    I buy a middle buster (Cat I 3PH) and try to make a garden. I can scratch around on the surface but can't bury the plow into the soil deep enough to be properly effective. I also have an interchangeable sub soiler "tooth" but haven't tried it yet. I suspect it would come up "short" as well. My implement is King Cutter. Anyone have a similar experience? Anyone know something about available adjustments? My lower arms don't have choices of where to connect them height wise. The right arm is hydraulic and adjusts higher or lower than left arm (tilt works).

    I just wanted to confirm that I haven't overlooked something simple but previously unknown to this inexperienced operator (first and only tractor, 300 hrs). Otherwise, if no good "fix", I guess I'll have to attack the darned thing with scrap metal and welding equipment to be able to mount it lower.

    Any help will be greatly appreciated and if someone solves the problem they will qualify to have their name entered in a drawing where they may win a swell prize.

    My lower lift arms have 3 holes in which to attach the lift arm links. If I use the hole closest to the tractor, I get more lift and more lowering ability. If you only have one hole possibly you can drill one closer to the tractor. You can unhook the lift arm and move it closer to the tractor to see how much lower and higher it would go.

    Patrick,

    I don't know about your tractor but on my JD 4610, the lift links are adjustable. The one side is where you level the implement from side to side but the other one can be adjusted also. I'd be guessing but I think I could adjust my lift links out about 2 extra inches. Two extra inches at the lift links should get you close to 4" at the end of the draft links.

    This is all speculation, since I haven't actually done it. Also check to be sure your 3ph hitch lever in going all the way down [img]/forums/images/graemlins/confused.gif[/img]

    Well, the side with the hydraulic you can lower enough I'm sure. The other side, left I'd guess:

    Some have 2-3 holes in the lower link. Use the one closest to the tractor.

    Some have 2-3 holes in the bottom of the lift link. Use the lowest hole.

    Some are threaded (no ajustment crank, just threaded). Remove the bottom pin, spin the arm around about 10 times, & hook it up again.

    If there really, truely are none of these adjustments, and the arms don't go any lower - then something isn't quite right.

    However, you have a pretty good option, since you put aside the regular (adjustable) right-side link. Put that one on your left side, and adjust it down with the crank. There you go.

    Before all that, I'll assume you adjusted the top link properly. Some implements like a super long top link, while others prefer the shorther version. Something to consider, a couple inches there can make a big difference. On my big rear mounted cultivator, 3 turns on the threads can plow up ridges of dirt, or keep the back shovels in the air...

    Thanks to all wlho replied. My dealer put the adjustable right side on the left when, prior to delivery, they installed the TnT. I have enough hydraulic adjustment to tilt either way, right now. If I crank the (now adjustable) left side down I won't get much tilt, except in the one direction. Still, I'll fiddle with that and see.

    I am some reticent to drill holes and weaken the bottom links. Maybe I can make a thing to attach to the lower links that will slide forward and back and tighten up when it is where you want it. Ten maybe a small hole for a smaller than "normal" pin would likely do the trick and not seriously weaken the lower links.

    Thanks for the suggestions and comments.

    Many tractors have adjustable limits for the 3 point hydraulics. You might check a shop manual for your model.
