Nuru--I used a rear dirt scoop on my Kubota B8200HST which is close in capability to your JD4100 and I also used it on my JD955 and it was a lot better than a wheelbarrow. I moved a lot of materials with it, but ignorance was bliss and I was a lot younger then and staying turned around in the tractor seat didn't seem to bother my body much then. Having used a JD FEL on two 4400HSTs, I can tell you that there is no comparison in using a rear scoop vs. a FEL. As I look back at owning a Yanmar, two Kubotas and three Deeres, and primarily using all except the 4400's as lawnmowers, I realize that having a FEL IS a reason to own a tractor whereas I could have probably mowed faster and easier with a Grasshopper, for example. People in my area (south of Kansas City) are STILL cleaning up after that last ice storm and I saw a person yesterday using a JD445 with a FEL picking up limbs and moving them and dumping them onto a pile. A couple of weeks ago I removed the bucket and added the forks, placed a pallet on them and helped my neighbors move their limbs onto burn piles. The FEL is way more versatile than the rear scoop--been there and done that! Good luck in your choice. Mike S.
