Q: Tractor driving.

when  ever I am working on a tractor down the fields my watch and/or phone tracks this as calories burned and exercise. When in fact it's not really very challenging. I sometimes spend 9-10 hours on a tractor and this seems to be messing up my activity tracking results.

My question is, are there any actions I could take to avoid this other than having to take my watch off And leave it at home?

Thank you.
