My Scag Turf Tiger (61", Kohler Command Pro 25, vintage 2001) has two Bussmann automotive type fuses, one 20A and one 30A. The 20A has blown 3 times and the 30A twice over the past five years. Is this normal? If not, any ideas what might be wrong?
Blow fuses are never normal but it happens for a number of reasons, shorts, overload, etc but the replacement fuses can also be at fault in a repeated failure scenario. Cheap fuses like those on Amazon or HF are notorious for poor rating, If it doesn't have white numbers then chances are they are junk and should be replaced.
The blue Bussmann has white numbers, the red one is cheap Chicom junk.

Trav...that's a great tip on the fuses! (Not just for lawnmowers.)
Thank you.
Try some heat shrink or some food electrical tape ( Scotch ) on the 5 wires , individually .Thanks all! The battery is new and holds its charge. I don't wash the mower with water, and the fuses have white numbers (some were bought at Napa). No idea what components these fuses are protecting.
When I installed a new PTO switch last month (2nd in three years) I noticed five wires in the control box with bare sections, i.e. insulation worn or corroded off. The wires were tightly bound and did not appear to be able to touch any metal or other wires, but I taped them anyhow. This was before the latest fuse blew. I'll have to look for more exposed or loose wires.
