long time, no run 856

Have a IH 856 in my Dad's shed that I'd like to restore and bring back to life. It hasn't been run/started in about 4-5 years but went into the shed in running condition. What should I do first so I don't damage anything? I know the batteries are shot, but I don't want to damage the engine. I'm new, so this might be an easy one, but I don't know. Any tips?
 
If its in the shed, you shouldn't have any serious problems. Check the engine oil and trans-hydraulic fluid of course. I'd drain the fuel tank and fuel lines and replace the fuel filter. Put in new fresh fuel and bleed it out.

I can't think of anything that you would ruin if its been inside out of the weather, other than you might have some seals that dried out and will now leak. You'll find that out soon enough when you start it up and run it for awhile. Sometimes tires will dry rot if they sit around long enough.
 
Loosten all 6 lines at injectors, open throttle as if starting and see if fuel is delivered at all injectors, if so it should start after all are tight. If no fuel may have valves and plungers stuck from stale fuel, will need cleaned and resealed to get working again. Just resealed a JD 4020 that had sat for 1 year, valves and plungers were stuck, looked like old wesson oil inside but worked fine after resealing. If pump does need to come off drive adapter should be removed and resealed also as drive seals are not in pump tube but in adapter assy. Old seals may be hard and cracked over time. IH also had 2 style banjo lines, some had a step on each side, used 2 18829 nylon washers on each line. Plain flat banjoes could use 2 copper or steel washers, or nylon washers with a steel washer to limit crush of seal. Make sure same is on each side of line or bolt will bottom in hole, head will seize, and shaft will break. Have seen it happen too many times in years past.
 
I'm tempted to just pull the plug and filters on the oil and start fresh. Last time I looked there wasn't any water or anything in the oil, but I'm not sure the last time it was changed before it went in the shed, so it's probably due anyway.
