Upgrading from the beginning

[ahr6912]

Hopefully you guys can help me on some good advice regarding upgrading.
Presently, I'm on a four acre residential wooded lot, using my Kubota L2501 which includes the BH-77 backhoe.
I'm looking to upgrade to the Kubota L4701DT.
BUILD:
L4701DT - 4WD TRACTOR W/FOLDABLE ROPS
FRONT 10-16.5R4 TitanTrac Loader ALR8869A
REAR 17.5L-24R4 Firestone All Traction Utility ALR6807
KUBOTA ADD-ON FRONT END LOADER - HEAVY DUTY FOR L4701
BUCKET LEVELINDICATOR L2130 BOLT ON CUTTING EDGE FOR 72"HD BUCKET.

I'm looking to sell my starter tractor with the backhoe which has only 190 hours on it.
Maintenance is up to date.
Here is a quick video, pardon the dirt on the tractor. the BH77 is cleaned.

what should I buy the new one for and what's the fair price for the old combo?

Tractorhouse.com is a good place to start researching for prices of used equipment but be advised that prices therein are asking prices and not considered representative of selling prices.

Insufficient information for much guidance regarding new 4701 replacement.
