I've got a Snapper Hydro Drive rear engine rider I use as a back up mower. Tonight I installed a bagger on it and tested it out in the back yard. Seemed to cut and bag OK but when I got off to check out how many leaves it picked up I noticed the muffler pipe was RED hot. It was actually glowing red from the heat. I've never noticed this when mowing during daylight hours. Do you think it just showed up more because it was dark out? Is this normal? Has this happened to any one else with a similar machine Out of curiosity, I got out my exmark lazer and drove it around and it didn't do the same thing. The muffler pipe didn't glow red from the heat it just ,of course, got hot but stayed the same color. Will be calling the dealer tomorrow, I was just interested to know if anybody else experienced this before.
