My 26 acre place in the CA mountains is mostly up and down, so a standard rear mower for a tractor isn't feasible (and the only option with industrial tires and a mid mower would be an L3940, a bit out of the price range). I'm looking at getting a GR2020. The standard turf tires will be too slippery for me and I see that bar tires are an option, but I can't find a photo of them anywhere. Can anyone help with that? Are they a better option for my needs? Thanks so much!
