Troybilt has historically made great products. I think most any tiller with a direct/gear drive transmission would work, preferrably with a rear mounted tiller. Arians had some good ones too.
Yep, I’ve had this one for only 4 years but it does a great job in the garden. I suspect I’ll have it a long time if I keep the ethanol out of it.
I misspelled Troybilt earlier. Being able to type 100 wpm has its drawbacks.
