I have For Sale a mid to late 90s model 520 - Hydro tractor with a 60" deck. 20HP Onan Engine. Forward Swept front Axle. Heavy Duty Spindles, and Gear Reduction Steering. Also has the Wide Rear Wheels.. Im selling this as a PARTS Tractor. I Got this in a recent deal and I have no need of it. It is Not Running and I have no idea why and Im not interested in finding out. If you put a battery in it, it does turn over and it does seem to have compression and gauges appear to work. Previous owner told me he was using it to mow and the engine just quit so I would say that the transmission is fine but I have no way of knowing. The 60" Deck appears Solid and everything turns free. It also comes with a brand new mule drive belt.. As you can see from the pictures the paint is faded and it has the usual dings and scratches.... 325.00 Buys It....If Interested or have questions Reply to ad or PM me. Thanks.
