Mid 70's we bought a duplex with a too-steep back yard. On two weekends I rented tiny tractors like that to make terraces with retaining walls. First rental was that model Yanmar with 2wd then the the following weekend a similar Kubota with 4wd. Surprisingly the Yanmar's loader cut into that undisturbed ground much better than the Kubota. I've respected Yanmar tractors ever since. 25 years later I bought the first of the two I own now. Both from that same late 70's era, the second one with PowerShift that makes it as versatile as anything modern. Yanmar's forever!
