Thanks all!
Hello,
Running in grass will really increase the amp load on your buggy. I would suggest starting with a 15 tooth or even the smallest you have 14 tooth, I know it will be way under geared but after running for 1-3 minutes check your motor and battery temp if you do not have a temp gun then if you cannot keep your finger on the motor for a count of 5 then it is way to hot.
If it is running cool then gear it up a little at a time such as go to a 16 or 17 and keep checking the temp.
Checking the temp is a good thing to do every time your run just to make sure there are not issues and you get max life out of your equipment.
Hope this helps
