BU-10L-122 transaxle drain and refill

[hansbrakob]

I have a beauty of an old 50" Craftsman lawn tractor, with one problem.

In the fall, in cool (around 30F or so) weather, the transaxle bogs down and quits working until springtime, when it works just fine again.

My guess is that the oil viscosity is too stiff (worn out oil, the unit is 20 years old).

The transaxle model is BU-10L-122.

For the life of me, I cannot find a drain plug (nor a refill plug) to drain and refill this thing with fresh oil.

HELP!!!!

Can not find a BU 10L 122
Can find a Hydrogear BDU 10L 122.
It has no drain so you have to pull it out and tip it upside down to change the oil.
Hydro gear have their manuals on line, https://www.hydro-gear.com/service-and-repair-manuals/

Drain & refill according to the manuals linked to in the post that you have piggy backed on to.
Nothing has changed since 2019
