are you pulling your excavator with a tamiya's standard semi truck?
I'm not sure if you remember but my first loader had bunch of problems, i had to send it back ( i lost 300$) and got the new one, new one is good so far. I never use them on the field tho so never push them really hard. I'm sure you will like it, at least it's more fun than my excavator for me and i'm sure you will put some decal on it, make it look even nicer
i created new tread on general discussion, my excavator and front loader are together in one of the pictures.
