Hi,
I recently purchased a Grasshopper 612/44" Deck with a Briggs V-Twin 12hp engine on it. The hydrostatic drive seemed a little noisy and deceided I was going to go through the entire mower changing fluids and filters and greasing etc. My question is on the Hydro's I pulled the plug on the bottom of them to drain but, when I took the bolts out of the top where you fill them it appeared there was still Hydro oil that didn't drain. I tried to suck out as much as I could with a syringe. Is there another way to completely get out all of the oil? Secondly, I've been told to go back with "Grasshopper" Hydro oil and nothing else... any truth to that? How full do I fill them since there doesn't appear to be a fill line on them. I would appreciate your feedback. Also, is there anything else I need to be looking at or maintain besides the regular oil, filter and sparkplug. If anyone can assist me I'd appreciate in your response.
Al
