Rotadairon RD 100 with Seed Box, in excellent condition, one owner/operator, I have all the original paperwork and owner's manual. Newer blades on the unit have a small amount of wear. The seeder box is an optional attachment that is easily removable when not needed.
43.25" working width, 3 point hitch, 540 rpm PTO, works perfectly on a Kubota B series or similar tractor
This is a well built, rugged, special reverse tiller designed for soil preparation prior to seeding or sodding.
In a single pass it will:
bury stones, clods, debris to bottom of cavity
blend in soil amendments like compost, lime, fertilizer, etc.
grade
roll
seed
It is also good for gardens, baseball and softball infields, and more.
The Rotadairon is made in France and is a tried and well tested design that has been around many years. This unit currently sells for about $15,000 without the seeder box. Blades and parts (never needed any, only blades) are readily available.
