Here is what I recommend,
Get an old used New Holland rolabar rake. It can be rusted and beat up and need work. You can usually get one for less than $2000. That is what my dad did. He bought 2 for haying and I just borrow one when I need it for the fall. Your New Holland Could easily pull it. Pull the rake around your yard or property and pull them into "windrows". Rake it all up into one big windrow and then pull a tarp up next to it. Hand Rake or Use a Leaf Blower onto a tarp. Then you can just put the tarp on a trailer or pull the tarp with your Kubota to your dump site. Then you also have the ability to rake hay if you ever wanted to. Thanks.
