This recent thread Stepped off with snowmobile on loader, almost tipped over got me wondering why tractors with loaders don't have a pivot lock to minimize the tip factor when using the loader. As it is, the tractor has the stability of a tractor with tricycle front gear. With a lock engaged to prevent the front axle from pivoting, the tipping force would be spread out to the width of the front wheels. I googled around a bit on TBN, but didn't get any hits. I'm thinking this is either a brilliant idea or a stupid question!
