An oil filter is less than $10 for a decent one such as the FRAM Ultra, and if you really don't care about the oil changes I would at least dump an extended performance oil in, if cheap is the way you prefer then go for QuakerState it is $21 for the new "Ultimate Protection" which is rated up to 20,000 miles.I've checked out brakes and fuel lines and they're in relatively good shape. Close enough for government work anyway. It is certainly destined for the junkyard. I suppose an oil change wouldn't hurt, that's something I haven't done yet because I've been wondering if it's even worth it. Its been getting topped off with our bulk 15w-40 diesel oil cuz that's what's around. FS brand I think.
Last farm beater went 5 years without an OCI, didn't matter in the end as a blown brake line is what sent it to the junkyard.
