Hi Moodoo, welcome to Outdoorking.

I don't think members can upload manuals to the manuals section, for technical reasons. If you have a manual for upload, please attach it to a Private Message and send it to a moderator.

We only have one previous thread on Austwood. See here:

For the interest of members, here are some pictures of an Austwood ZTR 1200 on an old for sale advertisement:

If you tell us what kind of engine you have, and post pictures of the mower, we can try to zero in on the information you are looking for. Do you mean you want to know how to drain the engine oil? If it is a Briggs and Stratton engine, we will need you to post the Model, Type and Code numbers which are stamped on the cooling air cowl, usually but not always near the carburetor.
