I had a '83 1710 for close to ten years, finally deciding to move up to a bigger tractor last summer. Mine had loaded turfs (unstoppable with chains in winter), easily handled a 5' Brush Bandit and even managed a 6' rear blower one winter. My wife bought a Woods 6 1/2' 3 pt backhoe with a
PTO-driven hydraulic pump, and I managed to do culvert excavation, dig out the occasional stump and do other projects for the neighbors. I was careful with the hoe as I didn't have the frame mount, but it would still loosen up case bolts now and then.
I would recommend testing the hydaulic system output before purchasing. Mine was putting out about 1900 psi max when spec is just over 2100 psi. Pumps are $700+. The other problem area I had was top case cover gaskets - if they are not in good condition, rain water can enter and dilute the hydraulic fluid. I actually had the fluid freeze one winter night, and I had to back it into the garage dragging the loader and thaw it out with a gas heater before fixing the gaskets and changing fluid.
