Due to diversification, have recently been looking at petrol lawn aerators - a quick search on here throws up a handful of threads.
Wondered what the current thinking of best models was?
Ideally working width of around 18" and ability to interchange between hollow and solid tines would be useful.
Sisis have produced many different models over the years with spares being or becoming a headache for lots of them....
Other options include Groundsman and Plugger - anyone have or use any of these?
