For stability it is primarily mind over matter . IF it's matter then use ROPS as your condom of protection ,not wheel spacing as angle on the hills alters vehicle reaction & is NOT a safety device. Rather, more a potentially FATAL trap for the uninitiated! The wheels are able to be adjusted only to set to the width of your crop or rows. IT will cause maximum wear on bearings and any other affected parts and if you do not NEED the wheels that wide apart you can minimise the loading by simply reversing the rim centres. The offset wont make noticeable difference. That said ,with the low hours and IF you are not a FARMER per se. The factors won't hurt the service it provides in current settings. At 8000 hours you may start to see why narrow offset as possible is best; but, won't that take you twenty years to reach? AND by then just maybe the rust will still be more concern as YOU drive it not your employees(possibly?). ENJOY!
