A lot of good comments here guys. I am not certain of the price difference between the two blades I mentioned - but will get that info. tomorrow morning when I call him again. I get really busy with work all day during the dealer's operating hours.
It is essentially unused, I hung it on the 3 pt while doing some loader work just to have some kind of ballast...I was in a tight spot and rotary cutter wouldn't have worked out
I am probably willing to pay for the difference cash, on the upgrade blade. It would be great if they offered it to me at their cost for my troubles, and my loss of confidence and trust in future advice/attachment purchases.
Regarding financing attachments - I'm not made of money and only had an extra $1500 but decided to put it all as a down payment. I understand deals are out there on used stuff - but the small amount it added to my payment for a rear blade seemed worth it. Too bad it's not really working out at the moment, but we'll see what he comes up with tomorrow.
The salesman is not the easiest guy to get along with, so if he is still being stubborn with me (trying to tell me he knows what I need, even though it's not listed as a proper attachment on Land Pride site... he also didn't know what a scarifier was and says he's never sold one...) then I guess the next step would be to write an email to the GM or owners and see if I can settle it with them instead.
I bit the bullet and went with Kubota knowing I was paying a bit of a premium, but figured top notch expertise and a comfortable atmosphere would be worth it - I'm starting to feel a bit disappointed that he's acting like it's a pain for him to get me sorted out right, and that I'm an oddball that he hasn't come across in 15 years because I want a heavier blade that is clearly spec'd for my tractor?
I'l keep giving him the benefit of the doubt until further notice. Thanks again, and I'll update soon.
