Plower, What kind of bucket level indicator did you have in mind? On my B7100, as with a lot of loaders, there was about a half inch rod from the bucket though a "loop?" on the right loader arm. You could set the bucket on the ground and get it level, then either paint the top of that rod, or cut it off level with the top of the loop. On my B2710 there is a flat strap of steel welded on the top of the bucket so it can be seen from the driver's seat. It is parallel to the bottom of the bucket so if it's level, the bucket is level. The problem with either one is that they indicate when the bucket is level on the ground only. And the type I now have depends on your being able to look at it from the driver's seat and tell whether it's level or not. Either one is definitely a help over having nothing, but sometimes I wish there was a better way.
