Tillers are very self-destructive, weight is a very important performance element, mine is a befco, chain driven, works well. Has option of using straight blades, duel purpose, can also aerate, a very marketable service to provide,
Have seen favorable reviews for woodmax tillers, appear heavy duty assembly. Not sure if chain drive or gear drive offers better long term longevity?
EDIT: been using mine for 5 years , believe some TBN folks have many more years of tiller experience. Subsequent posts will reveal the answer. Forward tine rotation = less required hp but brings rocks to surface. Opposite true w/ reverse tine, bury rocks but more hp req. Believe reverse tine leaves a more uniform and level soil consistency.
Five acres of tilling is a major undertaking!!!! Suggest one acre is more than I might find appealing!!!
I aerate about 7 acres 2x per year, but using straight blades, whole different animal, my tine bar is easily removable, change blades, inspect bolt tightness on work bench, not on my back!! 4 inches tine depth typ.
When tilling for client, who is responsible for rock collection/ disposal? Labor intensive, time consuming!!
