The southafrican manufacturer Dezzi has a tractor grader type MG80T: http://www.dezzi.co.za/page6.htm Here is a video from it: https://www.youtube.com/watch?v=QbUlUuTPujM
Interesting little machines those, not quite as popular as they potentially could be. The farmer grader market is still dominated by ex DoT Galion and Cat G series graders, and specialised equipment hire and use is still limited to skidsteers, and labourers due to a large, cheap labour pool. They are well built though, and super easy to work on and maintain.
Yes those small graders maybe interesting for smaller projects, I hope those types are coming out more in the future. Those manufacturers who built good big graders can built smaller types too. There are some projects which are too small for the big graders.
