THe machine pulls a few more holes than 9 in 1000 sq.ft. I hope.6'7 330 said:We have several LA IV Ryans. We acquired them new in 1996 and 1997.The best I can remember we paid 1600 back then. The pros to the unit are, less moving parts then many of the cam-driven, and you cant hardly ware them out. Replacing tynes and an occasional water drum, or chain, and youre back rolling. In addition, if engine blows slap another on there ,and youre plugging and back in business.
Among the negatives the Ryan is a bear for the workers to operate, operator fatigue will be high. The machine will only pull nine holes to a thousand square feet, making it necessary to do two passes for a proper aeration job.
