I would build a dirt ramp or gravel, as a temporary fix, or perhaps berm it up with shoring if you want something more permanent, ramps can get kind of funky after repeated use, not leading a to good outcome..
Failure with a dirt ramp is more noticeable, where as with ramps, they fail, or teeter more expectantly, the outcome may not end up well, particularly if you have the bucket fully extended.
Just saying!
