B3300 starting issue

[sidey4]

Hello
Issue with starting 2013 B3300 - second time now - got off the tractor to remove a branch caught up in bucket and she shut down - thought it was either the switch under the seat or the switch related to the forward/reverse pedal.
I checked it and relubed all as that had stalled me this winter but still no go - won't even turn over with key.
Any help would be appreciated - thanks

There's probably a neutral switch on the range selector also, as well as a switch on the pto. Seat switch normally doesn't affect starting.

It's your Operator Presence Control (OPC) switch, located just forward of the hydraulic filter right side, flashlight required. Spray some lubricant on it, has a rubber boot with switch plunger pin. In neutral, the pin should be depressed. Rock the HST pedal while under the tractor and note the pins movement after lubricating.
