Ride on tractor

[Itllbeaninterestingchristmas]

DS is about to turn 4 and we would like to get him a pedal tractor. Any recommendations?
We have plenty of off road hardstanding for him to drive round.

We've got a Rolly Toys John Deere tractor and trailer with front scoop. Bought from Robert Dyas but also seems to be available on Amazon. They have quite a range of different ones. Was an absolute pig to assemble but DD loves hers.
