Love the mower and always service it annually, but had a question.. I have seen other mowers that have drain plugs for the hydro, or they release the lines, does the 3100 have an easy way to drain the fluid? When I got this from the previous home owner he said he just vacuumed the reservoir to get as much fluid out, changed the filter and filled back the reservoir tank with fresh oil... Seems to me it would contaminate as there is a lot of old oil in the lines, pumps etc. Any thoughts on this? I have looked online for a service manual but have yet to find anything or any videos that describe this particular model. Can check on the year, but the unit has to be around 10-12 years old..
Thanks in advance
