Well, I can tell you exactly cause I have the receipts right here. Now, remember, I'm not dealing with a "discount" or internet dealer.. strictly a sticker price guy.. so this should be what you would pay any Kubota dealer.
The BH90B was $7100.
Then.. A BH4990 subframe mounting kit for the 3130 was $250
The BT2903 18" Bucket was $666.
And, a pair of L9467 rubber flip pads for the stabilizers was $100.. these are optional, but worth it if you are going to be using the backhoe on smooth surfaces like blacktop or concrete..
I also had to pay $75 each way for pickup and delivery..
So.. grand total $8266.. or $8116 without delivery charges..
You know what they say about the price of men's toys..
