Mahindra's lift ratings...

Re: Mahindra\'s lift ratings...

The rating for my three-point lift on my 4110 is measured at the lower link hitch point, which is a lot more important than 24" behind the lift arms. The lower link hitch point afterall is where you will be hooking implements up at. The 2865 lb. capacity is the same as is stated in literature. This is not the maximum possible capacity, as the max capacity would be several inches forward from the hitch points.

Just to throw another monkey into the wrench works, consider what you are spending to what you can lift. Reclassify the tractors by $$$ not gross hp, and see who can lift the most /forums/images/graemlins/grin.gif

Keith, that is why the general measurement is considered to be 500mm forward of the pivot point. It is a standard that will be measureable regardless of the shape of the bucket, or if the bucket has a QA system. It is commonly refered to as the 'bucket center' but really the common term is not precise. The precise point is a point 500mm forward of the pivot point.

Actually the most important rating is 24" behind the lift arms because that is where the weight is held. Even if the lower link pins are where it is attached, a typical box blade holds its center mass about 24" behind the pin points. A 5' rotary cutter would hold its center of mass about 36" behind the pin points. A 6' cutter holds it center of mass about 48" behind the pin points. If you remember High School Geometry class, think back to fulcrum points and leverage and how the length of the fulcrum changes the amount of weight needed to move an object on the other end and the variable of the fulcrum position.

Varmintmist . . . you make an EXCELLENT point and has been pointed out by SonnieP, sometimes you get more lift capacity than you need as a result of buying the HP or size you need. Nobody ever questioned the quality of the tractors, just the measurement points. As an interesting side note, it appears that the NEWEST literature from Kubota may (for the B3030) may now rate their FEL at the Pivot Points so even the big dog of the industry may be changing with the times. I have not seen the newest brochure, but a very reliable friend passed the information to me about the Kubota pivot point ratings.

Re: Mahindra\'s lift ratings...

I think the terminology often leads to confusion. Kubota advertises their lifting capacities as 24 inches behind the lift point. The lift point isn't a real clear term. The point at which the yoke rods attach to the lower links, the point at which the implement attaches to the lower link can be construed as being the lift point, as could the point where the lower arms attach to the tractor. I have always construed the 24" behind the lift point to mean 24" behind the point at which the yokes attach to the lower links. It is obviously open to interpretation.

Hitch point lift capacity is pretty clear terminology, as it clearly indicates where the implement connects to the tractor.

The action of the lift is more complicated than a simple lever-fulcrum setup. The multiple pivot points ends up being several levers and several fulcrums.

Keith,

The 24" behind the lift point is the theoretical weight center of implements. The lift point that is being referred to is the pin holes on the extreme end of the lower lift arms where the implement is attached. The entire three point system is considered as part of the tractor which includes the lower lift arms and the third arm

Re: Mahindra\'s lift ratings...

Jerry, thanks for clearing that up. I can see how it is referred to as the theoretical center, as when the 3PH was first developed the implements tended to be smaller. I would think the actual weight center varies greatly.
