As a new owner of a JD 1023e, I've been reading through a lot of posts here, particularly covering the oil, tranny maint./service schedules.
It "appears" to me, the largest quantity of fluid we will need to change out is somewhere in the 16 quart vicinity/capacity.
It came to mind that, instead of tossing $$$ at the Auto Zone/NAPA big-box stores to purchase fancy schmancy oil catch-pans, why not just measure from the ground up to the tranny drain plug, subtract 4" from that measurement, and cut down one of the plastic 55 gallon drums that most of us have laying around that's not in use?
Using a magic-marker, or white paint-stick marker, transfer the measurement from the bottom of the barrel and mark in 4 places, take some sheetrock tape, attach one end to the barrel on one of the marks, wrap the tape around the barrel and scotch-tape it in those 4 marks, then make enough marks at the sheetrock tape where the marks intersect each other around the entire barrel until you have enough marks to follow the "cut-line" around with a 4" grinder and a cutting disc attached to it.
When the final cut is completed, just clean up the frazzles of plastic on the fresh cut end with some #80 grit sandpaper, which will help eliminate any accidental cuts on your fingers/wrists, etc.....
I apologize for the long explanation, but, coming from an engineering background I've always taken the time to try and fully explain my thoughts precisely, so, I thank you all for bearing with me on my long-winded post.
Hope it's clear and helpful......
