I have no idea what the dealer was quoting for the backhoe. You should always get a break down of each item so that you can deal with just this type of situation.
Tractors may be sold as a package, but the dealer knows how much he/she is charging for each item, and you should too.
In general, I would recommend you get a Woods backhoe. It is made very well, and has a better, in my opinion, method of hook up with a strong 4 pt connection. The groundbreaker 6000 is a good hoe for the CK20. I know at least one member is using their 70 hoe, but I think that's very heavy for the CK20.
The price of the Woods hoe may be a little more than the Kioti.
I think the Kioti hoe is retailing around $5,000, but I'm not positive of that as prices of everything have gone up over the last 3 years.
I'm not sure if the Woods backhoe would require that you have the Woods loader, but if so, it would still be worth doing in my estimate. I've been meaning to find out the answer to that, but I keep forgetting to ask my dealer.
Maybe Rick Wallace can answer that for us.
