Increase 3pt lift capacity

[nyone]

The easiest and cheapest method to raise lifing capacity is to move the center of mass closer to the tractor.

One can also relocate lift linkage on draft arm closer to load on 3pt point hitch & increase lift capacity. Note location of green dot that will relocate lift link closer to implement. Relocating hole in draft links will change maximum & minimum heights of attached implement.

New here. I'll try and make it short. O have kind of same question as poster BUT will be specific with situation and WHY.
Looking at KIOTI CK4020SEH with lift capacity of 1631lbs. the impliment I need to lift is 1388lbs on a regular. Meaning, impliment is a Verti Drain aerator. Will run/operate for 20-50ft then lift, turn around and drop and run again. 100 times a day.
The limits are to close for my liking. I DO LIKE THE OVERALL SIZE AND WIDTH (very important) of the tractor. I know I can go up a size for tractor, but I want to make sure that is the ONLY way to make this work. After reading around I think you guys are awesome and would know my options.
Many huge thanks in advance.

Probably the cheapest solution would be a hydraulic top link, especially if you have rear hydraulic plumbing. Retracting the HTL would curl the implement up, which might be enough clearance to suit you. It would also move the implement's weight forward so you could possibly get further lift with your 3PH.

Whatever you do will probably exceed what your tractor was designed for... And if a PTO shaft is involved, the telescoping could bottom out.

OK, I've done what you are trying to do.

What you need to know first of all is that a "lift capacity of 1631 lbs" is only half the story. You need to know how far behind the 3pt that 1631 lbs is being lifted. Most tractor manufacturers - but not all - specify 3pt lift capacity as a vertical force positioned 24" behind the ball ends of the lower lift arms when those arms are horizontal.

The closer the weight is to the ball ends, the more weight can be lifted and vice versa.

But specifying lift capacity at 24" behind the ball ends is not a law, just a convention.
As a result, just like FEL lift is exaggerated, the published 3pt lift is a fertile field for advertising hype. You need to know the real numbers, and they are available - usually in the shop manual.

So first find out how Kioti is calculating the 3pt lift on that model - that will get you in the right ball park, and may tell you all you need to know right then.

For a more exact calculation, go to the Virti Drain implement spec sheet and look up what their implement distance is from the 3pt hitch mounting back to the Center of Gravity on the implement. Then check Kioti's 3pt lift spec for that distance.

Hope this helps,
