So far my set-up seems to produce decent-looking results. Gator G5 blades, front slightly higher, and I don't have to mow 5-6 yards/day so I'm not in any hurry. Still 'speriminting with DIY striping ideas. The heavy door mat ripped after ~ 6 hrs.
I think you need to throughly clean your battery cables and make sure they are tight. Also throw a volt meter on the battery and get a reading before you try to start it and then DURING trying to start it.
Is there a suitable tranny filter for my grandson's Z520A other than the $45/ea. from JD? Sure kicks a $100 bill in the behind just for a lousy filter change. Plus, I use 15W50 in my Gravely. What should I use in his 520? And 2 quarts each?
