Basically, I glued some thick leather strips onto the top of the wheel well on the inside of the hand grap rail to cover the paintjob up and give the bottom of the chainsaw some cushioning.
Then I just set the chainsaw up against the grab rail with the chain bar cover slipped rearward between the ROPS and the handgrab bar. Then just take a rubber tie-down stretch with grab hooks on each end and wrap that around the chainsaw handle (pointing toward the steering wheel) and the grab bar.
Works excellent, no rattles and zero interferene with operations, you can even rotate the seat back for the BH without any problems as it all fits flush up against the inside of the grabrail on top of the wheel well. The bar doesn't stick out far enough to be contacted by the rear BH stabilizer when it is raised too.
I don't have a pic right now of it, but I'll take one. It is a super sanitary installation with no hassles.
