KL120 Loader Flexing

KiotiJohn · Apr 1, 2006

Tom, it doesn't sound like much deflection at all.
I had a job taking out several stumps today, and while using the backhoe, I notice that when I was on uneven ground, and put the loader all the way down that one side would be on some high ground, and the other on lower ground. It flexed enough so that both ends of the bucket were on the ground.

I didn't have my camera with me, so I couldn't shoot it, but I notice that the cylinders seemed to compensate as I pushed the bucket down. One out some, the other in some.

Since I'm no hydraulic man, I don't know if that is the way it should be or not. I did notice however, that as I was doing some loading of the dirt piles, the loader moved up and down from end to end just a little, digging into the piles. I almost seemed like a cutting action, working the loader into the pile, so it seems to me that the little flex is actually helping, but I can't be sure of that.

The tractor is still on the jobsite as I have some leveling to do there tomorrow, and a sewer line trench to dig. If I can remember my camera, I'll try to take a shot of the same test Steve did. I feel sure I'll get about the same flex.

I did not detect any cracking in the loader today. So far, so good. I would really like to see someone do this with the optional Woods loaders on a CK20 and CK30 as well. They always have seemed sturdier to me.

( However, you seem to have the one Kioti that does not fit all the rest. Now I'm confused, and if it's true, concerned. )
Dargo, I don't think we can say that yet, as we have not really seen many KL130s doing the test have we?

True, but one with basically zero? /forums/images/graemlins/confused.gif I honestly do NOT think all the others are bad. I really don't.

Factory spec weight: Total (lbs.) 3064
No mower installed but, box blade on 3pth
Lift capacity of loader at pivot pins: Lift Capacity to Full Height @ Pivot Pins 1020 lbs.
I could try it in the barn but I just put it away for the night. Maybe tomorrow. It was a long day.
All specs are from Mahindra USA website. I don't think the weight of the loader is included in the weight spec and I can't find the weight spec on it. I think the loader is a little on the light side, as compared to others I've seen, but it sure has worked for me. One of these days, I'm going to weigh the material from a full bucket and see what it actually can move.

Bob, i was looking at your pic comparison, your bricks should be put flush with the outside of the loader and turned lenth wise , like those in the k120 pic, placed where they are is not the same comparison. I have the woods 1012 on my ck30 and ill try that as well on my tractor tomorrow...

HODAK · Apr 1, 2006

albmn10 - you make a good point. Different width blocks, a placement closer to center of a few inches etc, can really give different results even on the same machine. This is interesting stuff though.

Bob_Skurka · Apr 1, 2006

Yup that is a good point. The loader was on the edge of the block so it was not in contact with the full width of the, but it was probably 4 inches in from the edge. That could certainly account for only 1/2" deflection. Even so, I doubt it would have had the large amount of deflection that Steve had. I'm not home today so I can't redo the test for a couple days.

Steve,

Here's how the KL130 access hole, on my FEL, is reinforced with ~1/4" steel in the corners.

I had the blocks about halfway between where Steve's were and where Bob's were.
Tomorrow, I'll move them closer to the edge.
Not being a physics major, does it matter if the bucket is flat on the blocks or if the back of the bucket (rounded part) is supporting the weight? I had it flat.
I also checked. No cracks /forums/images/graemlins/smile.gif

Just another comment about the whole k120- k130 designs. Having the hydrolic lines inside the loader crossbar does protect them from heavy brush or objects.. On my Woods 1012 the crossbar is very heavy duty with the lines somewhat exposed . Their is a standoff guard mounted on the surface of the crossbar. I am also a little wiser now about this configuration because i actually ripped my guard and lines right off my tractor last fall pushing over a 6 inch oak tree. I grabbed the tree a bit too high and the the tree snapped in half dropping my tractor on the guard and hydrolic lines.. With the lines inside the crossbar id bet they wouldnt have been damaged. A good lesson to remember , be careful when pushing trees over not to ride too far up the tree.. I do however think that kioti should be putting a heavier duty plate and backing in the cross bar area.. I guess their are pros and cons to both designs.. Just my opinion..
