I replaced the battery on my peg perego riding tractor with trailer and it still is not working. Wheels are turning so that doesn't seem to be it. What else could it be?

Hi!
On these, only the 2 rear wheels are the gear wheels. You will just need to replace the tires on those with the rubber ones if you choose to go that way.  Good luck!

I have the same issue. Called their customer service and they said it was a defect in the charging system. They are sending a upgrade kit for free, but when it's installed you can't charge the battery using the rear port anymore. No big deal. I'll report back when the fix is complete. 5-7 days until it gets here.

The Peg Perego Gearbox is the item that would make a clicking noise or grinding noise.
There are two different types.
One is a cross shape and another is a pentagon shape.
If you contact the folks at http://www.shopjandl.com/ they will be able to tell you what type you need. I get all my parts from them because they help me figure the problems out.
Hope this helps
