I just bought a Kioti DK45 with a self-levelling 1590 loader and Skid Steer coupler. This is my first tractor/loader so I am unfamiliar with what is normal. The previous owner added the coupler and welded an adapter plate directly to the back of the bucket. The bottom of the bucket curls back only to about 10 degrees above level, which seems too low for keeping a load in the bucket, but the total curl angle is 110* so when dumping the bucket bottom is 10* negative (past vertical). I am contemplating having the adapter cut off the bucket and re-welded at a higher angle, probably 30* to the ground at max. curl, meaning that the max. dump angle would be 10* positive. Given the restriction on the total angular movement, what would be the best compromise between dumping and curling back?

You may want to use it just as it is for a while ,one reason they don't tip back very far is so that you don't dump the load on your hood.

That and allow full dump at max height to load into something.

That does not happen with a self-leveling loader like his.
As Xfaxman points out, this loader maintains the bucket angle relative to level regardless of the height above ground. I already dumped the bolt-on forks out of the fully curled bucket while moving around on uneven ground, so I am pretty sure that the bucket needs to tilt back more. The question I have is how much given that more than a 10* change means that the bucket bottom will not reach vertical when dumping. It appears that many loaders have a greater total rotation angle than this one.

I was hoping someone in with knowledge of dump angles would answer your question.

FEL Rollback and Dump Angles
If I had any experience with FELs I could easily answer this on my own, but I would like to factor the relevant information into my buying decision. On the bigger FELs, total bucket movement seems to be in the 85 to 88 degree range. How they're split between roll back and dump functions...

FEL Geometry
I am looking for some advice on dump and rollback angles for my home made loader. After searching around a bit it seems that an average dump angle id 45deg and rollback about 27 deg Firstly does this sound correct? Also is it correct that the rollback angle is measured with the bucket flat on...

Minimum Angle to Dump Dirt
Looking for cheep dump trailer for my pond project. CMI six foot one ton with factory hand pump dump kit, less wood delivered is $682. With a dump angle of 40 degrees I have no idea what to expect.

Is the loader the KL1590?
Jim, it is a 1590.
Xfaxman, thank you for the links. I didn't do my homework with this loader and it seems to have real limitations but it's mine and I have to figure out how to make it work as best as possible. As configured, when fully rolled back the bottom of the bucket is 10-11* above level no matter what the height above ground. The dump angle varies however, from 100* below level (10* beyond vertical) at the ground to only 45* at full height. At about 78" from ground to tip of bucket the dump angle is about 60* below level. I am currently considering having the attachment plate cut and rewelded with a 15-20* wedge plate between it and the bucket to allow for better carrying loads without spillage. I will lose dumping ability at full height and presumably lose bit of weight capacity as the load will be slightly farther away from the loader arms.
The quick attach adapter is made for the 1590 loader, judging by the model on the id plate. I believe the bucket originally had wedge shaped plates which engaged with the loader arm pins, whereas the previoius owner cut them off and welded the quick hitch plate directly to the back of the bucket. I did check that the adapter was not limiting the curl cylinder travel as the piston arms do not completely retract into the cylinder.
I would be interested to hear from anyone with this loader as to the standard working angles and what would be my best approach. It's interesting that there is such a wide variability among various loader designs.

I found this one. I did not read through the whole thing but it looks like the highlights are that the less than ideal roll back is a known issue that Kioti fixed with this kit. It also says you should have 33 degrees of roll back.

NEWS ON THE KL1595, 1590 LOADER ROLL-BACK FIX KIT!
Great News- I talked with the president of KMW this am and he told me that the first "kit" with my name on it had been sent to Kioti to be forwarded to my dealer for an install next week. He said that (with Kioti's approval) they were changing a number of loaders this summer. The Kit will...
