Started last year, but only after the tractor (M4050) was warmed up to operating temp. If I shut down, when I tried to restart I could hear a dull sound of the starter trying to engage. After a few more tries, it would catch and start. Now, it's happening more frequently and happened yesterday when I tried to start the tractor cold. It seems if I hold the starter switch and/or quickly cycle it, the starter will eventually catch and start. The starter was replaced last year and worked fine for a few hours until the ''hot' start issue seemed to start. I initially thought it was the wiring for the gear safety switch, but again, I can hear the starter trying to cycle which eliminates the safety switch since the power would be cut to the starter. Any thoughts? Thanks!
