I'll take a look but I dont have too many trees on the property. Lots of field.If you have a hydro trans, I've had it happen twice exactly the same. Jumped off and it wouldn't restart. Both times it was a branch stuck in the safety switch for the pedals (they make sure they're centered before starting). Not sure if yours is the same, but worth looking. I have since bypassed that switch so it won't happen again.
Yes I tried this and I got 1 click. I pulled the starter 3/4ths the way where I could see the spindle inside. It engages but doesnt spin. I used a truck jumper box. Battery has been tested by autozone and napa. Both say it is good.The sounds like a bad solenoid and/or not getting enough amperage. I had the same problem with my Kubota. Make sure you are jumpering with thick enough cables.
I would take booster cables and hook the negative from the battery to the engine block and the positive from the battery positive to starter always on terminal and then use a thick gauge wire to jump from the positive terminal to the "start" terminal. If you still get grinding and clicking then you probably need to replace the solenoid.
If you have older GM cars then you probably know a lot about bad solenoids and if you have an GM car with headers then you definitely know about bad solenoids
