Well folks, it really helped to hear from you all, and to set my expectations appropriately. Safety first is always the good rule, and I was glad I did extra reading on TBN for warnings & no-no's, as well as techniques.
Long story short, I got all the berm backfill dirt moved, I got all the rocks moved (didn't have to dig them out, as mentioned by a previous poster, just move them... I'd rolled or dollied every last one down our considerable slope, so they were sitting beside the dirt drive), I made an attempt at the swale, and I did some driveway infilling and leveling. Wah! It seems incredible the amount I got done. Having my brother here for the rock-moving part helped, as we positioned the JD, slid/placed rocks in the bucket, carried them to the new backfill, and then he directed my positioning of FEL for easiest and most accurate unloading.
So for an absolute newbie, all the things you guys mentioned were useful. Here's a few more that I "learned" while in the seat:
- If your wheels spin while digging with the FEL, watch out for the ruts you just created

- The range shift lever either slipped or I bumped it getting in and out... three times. Not sure which. In any case, finding yourself in neutral when you expected mid-range is not a good thing.
- The tractor handles very differently with FEL loaded vs. unloaded... be aware of the difference.
- Sometimes the hydraulics seemed speedier/more jerky than others. Be careful if bucket lowers fast and then taking hand off the lever (stops bucket). This can lift a rear wheel (as I found out... twice :ashamed: ).
For all my work newbie-ness, I have only one battle scar: a small tree branch got pulled back by ROPS, and then branded me across the cheek as it let go. It'll make for fun stories at work on Monday.
I'll post before-and-after pics within the next 24 hours. Thanks Again! :thumbsup:
