That looks like a fairly decent package. From what I've read the owner is asking $1000. So maybe he has some wiggle room on price depending on what issues you find with the tractor or attachments. Also you have to look at it as you have a complete large frame with alot the goodies(attachments) at one place. When I bought my HT23 I got a plow and sweeper with it, Niether I needed really. So I attempted to sell/trade those attachments for ones I wanted and could use. Well it turned into a big hassle, nothing worked out, attachments were hard to find close to home, so I barely used the tractor because I didn't have the attachments needed. So someone offered me my money back for it, and I let the HT23 go. Do I miss the tractor, yea, but unless I found attachments it was just gonna sit so I let it go. So if you can use all that in the package, that is a huge time and money saver getting it all at once. If you can't use every attachment, well you could always sell what you don't need to fund repairs to the tractor or offset the initial cost of buying everything. Just break down what your getting in attachments and what they could be sold for:
Rear Blade- $75-$150??
plow- $100- $150??
Wheel weights- $100-$150??
HT20- $500 easy.
I'm probably a bit light on alot of those prices, but its just to show you that if you could grab the tractor for alittle under his asking price, or even his asking price, it seems fair to me! If the tractor is not for you, then I see no reason why you couldn't seperate and resell everything and get your money back.
Good luck, and let us know how you made out!
I think your right on track on the prices,that seems to be an average price,the tractor you might be a little low on, (IMO)
