Default Re: Kubota B21 TLB complete driveline rebuild

This is the so-called main frame (or main flame, as it is called in
the parts book).

The main frame weighs just a bit less than 200#, but seems to
be designed to maximize the rigidity of the b/h mount. 1.5"
pins, too. This style of subframe is what I used to model my
custom subframes after.

The second photo shows that the upper pin does seem to get a
bit of wiggle.
