Keep in mind that the 2 machines you mentioned are dedicated TLBs and Kioti doesn't make one. You can add a BH to any tractor, but it isn't quite the same as a dedicated one.
Ditto.
Not even a fair comparison for the kioti....
The loaders spec out nearly identical.
Total operation weight is similar at around 7k
But.....Lets talk about them backhoes....
............................................L39.....................................kioti DK40 w/hoe
Dipper diging force...............3800#.........................................2000#
Bucket force........................5800#.........................................3700#
Reach.................................160"...........................................130"
Digging depth........................10'.............................................8'
Not to mention the L39 will likely be faster, with about 50% more GPM of flow...
Not even fair at all. A fairer comparision would be Grand L3940 with BH attachment. But then you are nearing the price of a L39, with a weaker loader and smaller hoe.
Price wise, the kubota is going to be around 40k. Not sure what the kioti's run, but withOUT the hoe, I think they are around 25k, so add the hoe and your looking at low to mid 30's.
I'd say about a 6-7k savings going with kioti, but if you are serious about BH work, the L39 IMO is going to be worth the extra...
