Thx, Lucas
That is a VERY low price for a serviceable tractor with hoe. You did
extremely well.

Very interesting about the forks breaking on the rental. That means they
must have cracked the tractor to fix each time. $$$! Most
CUT gears I have
seen are straight-
cut and unsynchronized. That means shifting is not
always easy. (I know there are SOME tractors with synchros, but not mine.)
Renters would force the shifters, for sure.
The rental company I bought my earlier rentals from found out the hard way
that they do not want tractors with clutches, and they disable the higher
range(s) in the gearbox (no range shifting).

One of the pix I posted shows removing the midframe from the clutch housing.
If you ONLY needed to get at the clutch, you could separate the tractor
only at the front of the midframe, instead of at the rear like I did. The clutch
housing on this tractor is sealed, BTW. I do not know how common it is with
tractors, but I have seen plenty of dry clutch housings that have drain holes
and vents. If this particular B21 had a drain hole, there is a good chance that
the small main seal leak would not have pooled up high enough to soak the
friction disk. Of course, that's just my opionion....I could be wrong.
