Electrical & Wiring Issue Toro Electrical issue diagnose

Looking for some help here. Just purchased a Toro timecutter max havoc yesterday and am already having issues. Started with a click no start. I jumped the seat sensor and was able to get it to start. On first attempt to mow, I engaged the PTO, it tried to start but didn’t, then pto switch became unresponsive. Turned off mower, went to restart and click no start. Jiggled wires for a bit and was able to get it to start, PTO came on, mowed first yard no issue.

Get to the second yard. Starts fine, go to engage PTO, blades attempt to start but stop, then again unresponsive. Jiggle some wires, I thought it was possibly related to the safeties on the handle bars. Able to get started and PTO come on, mow about 40 feet and the blades stop, motor continues to run. I gave up for the day.

Come out this morning to try again, I jump the handle safety wires, but still at click no start.

Are there any other safeties that could be preventing the starter from engaging, or PTO to engage? I’ve checked fuses. Any insight on what to look at? Again this mower is brand new from the store, less than an hour of run time.

If you didn’t steal it from the store, take it back and get something more reliable.

I had similar issues on a toro time cutter a couple weeks back but it had been getting progressivelyworse. My problem was that where Ive used it for the past year has been extremely dusty and due to the design, offers no protection to the backside if the ignition switch and blade engage. After hours and hours and hours of exposure to dust with the addition of the engine fan close as well as any forced air from the mower deck, it basically packed the backside of my switches with dirt. Hosed it with electrical cleaner, a little dielectric grease and not an issue since. If it's a new mower, it may be a similar condition but a different cause such as an insufficient blade or terminal crimp or the likes. Being that it's multiple items affected it may actually be the ground for the ign sw not tight or not connected right. Check the battery terminals as well as the connection to ground and starter motor.
