As three point hoes go, this one is fairly large with a long reach. That is useful. I also like the manual, one of the better ones out there actually - and now you'll have it. You may need to replace all the hoses, redo the seat and the cylinder seals may leak - it's obviously been sitting by itself for a while - that should be considered in deciding on a price. Hoses and fittings are costly - even if you have them done at NAPA instead of a dedicated hydraulics shop. Check on line for the price of TPH hoes, used and you'll get an idea if this is one you want for $1200. I do believe that price is north of what I would pay.
On the other hand, once you've had a hoe, you will never go back to a shovel - I love having one and find it useful for all sorts of tasks - including rear ballast for my 4n1 bucket.
