Hi Jack
Im going with that dimension, local wood turner will make me a set of beautiful Jarrah hardwood rollers.
The SB 17 I have been using is sitting quite smug in the shed and I think has been telling the imperial its no good as it hasn't cut a lawn for 30 years !
The plan is to send them both for a professional sharpen and set, then divide the lawn into 2 sections and see how they perform. The weather in Perth looks ok for the next week or so, so will be interesting to see the results are if I can get the blade sharpening done in the next few days.
Ill need to get the height adjuster organised but doesn't look a big issue ( says me ! )
Cheers
