I'm not at familiar with the Mahindra and Yanmar, but I will note at least one spec that isn't a direct comparison on the Kioti and Kubota. The lift capacity for Kioti are listed at 1520mm pin height (approx 60in) where the Kubota is listed at the full 95in pin height. The Kubota is rated at 1431lbs at 1500mm pin height.
I couldn't find the lift capacity at full height for the Kioti, (I'm assuming you spec'd the 4030 loader).
Another thing to look at some you said you wanted a backhoe is the attachment method, I'm not a huge fan of the large subframe on the Kioti, it takes up quite a bitnif space when it's off and is a bit more difficult to mount up.
Went through this a couple years ago with a friend who was looking at a few different tractors and bought a Ck2610, its a nice machine and he likes it, but I definitely would rather have the Kubota backhoe mount.
Also while I feel the Kioti has a better loader joystick placement then the Kubota (I'm a fan of the fender mounted sticks) I felt the Kubota valve itself was much nicer/smoother to operate then the Kioti.
Just a few things to consider.
