Hi, what's up! Looking at a used 1999 Bobcat 453 with less than 950 hours on it. - How much would it be worth? - I'd be using it for moving dirt as well as running attachments: a small 38" tiller, ditch-digger, stump-grinder attachments? Basically, what is this unit worth with just the bucket and would I need a bigger unit to run these implements without problem (mostly concerned with the tiller)? Thanks in advance.
