I have a 2010 loader and my model is a 820. It lookes the same. My bucket size is one cuyd.
All the hydraulic hoses are there but the return lines are rotted. There is no hydraulic pump to power it. The pump normally fits on the back PTO of the dozer. The hyd cylinders look good, but you are buying this AS IS.

The bottom mount brackets are there. The rear has the weight attachment and bolts right to the rear axle.

The reservior looks OK with the internal filters. I am not sure of the internal filter condition.

The control valve is free and not rusted tight.The front bucket has seen some use and the teeth are fair in quality.
This unit is located at a consignment auction in Ohio that will go on the auction block Jan 31 (thur). I will bid for you. I do not own this unit, just trying to save it from scrap iron.
If I get the winning bid, I will add 20% for my services to bid on it and move to my farm 20 miles away. I have a way to load it from there on your trailer. Then you can come later to pick it up at zip code 43040. Free outside storage at my farm for a resonable amount of time.
I will expect full payment within 14 days of the sale. There are NO RETURNS on this.
If you are interested, send me a personal message as to your highest bid for the loader, not including my 20%. I will do my best to get it for less. The highest bidder limit to me with have the first chance for the unit. If they back out, I will offer this to the next in line. I will notify the highest bidder by personal message the day before the sale that you might be the proud owner of the loader the next day.
Feel free to ask questions. The deadline for bids is midnight Jan 29 (tuesday)
