My only negative comments are with regard to the booklet of directions and one of the fittings for assembling the tractor.
The tractor is very true to life and amazing! I don't expect the assembly directions to be simple for such a realistic and functional item. However, the directions are given in pictures only. I've put together baby's and children's toys/cribs/strollers/climbing apparatus/etc. for over 8 years now and have, reasonably, accomplished the new (even if extremely aggravating!) assembly-without-words routine. This particular assembly, however, would have been much less aggravating and time-consuming with at least minimal written directions. I understand, as a cost savings to the manufacturer, pictogram directions require no translation into a multitude of different languages thereby saving printing costs for a company that ships these items worldwide. By all means, charge me the extra nickel it costs to print written directions - plus markup. It's worth it to the consumer.
The longer metal rod that connects through the front of the tractor at the 'scoop arm' is very difficult, if not impossible, to get to connect to the metal 'button' fittings. If the rod were 1/4" longer, the buttons would be able to be fastened with ease and without sacrificing any of the working features of the tractor.
Overall, the tractor is great! Just be sure to allow PLENTY of time for assembly.
