I’m not super experienced on my BH 92. I can remove stumps, dig holes and stuff like that. I now need to dig 3 100 foot trenches and keep them level. Any tips would be appreciated.

Level as in flat for 100 feet.Level as in flat or level as in consistent depth following existing grade?
The easiest way to do it is paint a line on the front edge of the bucket facing you at whatever depth you want to dig your trench. Couple that with what D2 told you and you're almost guaranteed to have a consistent depth trench.
Short of a laser or transit.....Level as in flat for 100 feet.
or an AUTOLEVEL.....or a laser level....Your gonna need a transit.
Maybe check this video out...tips on keeping the bucket flat https://www.youtube.com/watch?v=Koa56PuOYOQLevel as in flat for 100 feet.
I just dig it a little too deep, and then backfill as necessary and check with the laser level. Seems easier than trying to dig it perfectly.
Please go on, advise.Also keeping your bucket flat is probably the worst thing to do when digging out a trench. Its a horrible habit to get into for several reasons.
I concur. This would be nice. https://www.amazon.com/Johnson-Level-Tool-99-005K-Manual-Leveling/dp/B00ME77KH8/ref=asc_df_B00ME77KH8/?tag=hyprod-20&linkCode=df0&hvadid=309849796982&hvpos=1o1&hvnetw=g&hvrand=2965215896813161924&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9011319&hvtargid=pla-641878817512&psc=1Your gonna need a transit.
Teach me your reasoning. The jobs I worked on, the pipe was laid in the ditch (it was usually long joints) and bedding provided to make level as measured by transit.That is NOT what you want to get in a habit of. Any “trench” floor should remain virgin material. You never want any trench floor to settle.

This explains it.
"Rigid Pipe is designed to transmit the backfill load on the pipe through the pipe walls to the foundation beneath the pipe. The pipe walls must be strong enough to carry this load.
A line load at the top and bottom of a pipe is the worst possible loading case. If the load can be distributed over a large area at the top and at the bottom of the pipe. the pipe walls will not have to be designed as strong as for a line load. The backfill load is normally well distributed over the top of the pipe. However, proper pipe support must be constructed on the bottom of the pipe to distribute the load.
Proper soil support under the bottom of the pipe is also necessary to maintain grade (elevation) of the pipe. Continuous, uniform support under the pipe prevents unequal settlement of the pipeline.
If a rigid pipe is overloaded, or if the load is not distributed around the pipe, a rigid pipe will fail by cracking"
Here's a link to The Dept of Interior Bureau of Reclamation's technical bulletin. Look on page 16 for a picture. https://www.usbr.gov/tsc/techreferences/mands/mands-pdfs/pipebed.pdf
