Hi Legman; welcome to TBN - first, you'll likely get more action if you change your profile to include general location, maybe down to state. Otherwise some recommendations you get might only work in the swamps of Louisiana, for example.
The good news; I was an electronics tech in several of my "past lives", now have 2 older tractors and a full-size Case backhoe, bunches of other related stuff. IOW, it's doable :thumbsup:
The BAD news; very few of the tools you may have acquired previously will help much on tractors, even a small one :laughing:
I'd not heard of Hinomoto before, but Tractordata.com has (sorta)
TractorData.com Hinomoto E16 tractor information
Looks like that tractor was only made for a couple years from 1977-1979; on this page,
TractorData.com - Hinomoto farm tractors sorted by model
it mentions that Tierra is the new name - one of those instances is actually a
link to their website, but I kept getting a timeout when trying to access it. If you ever can, they MIGHT have info on your tractor (or even downloads, if you're REAL lucky) - but I'm thinking it may be history.
Looks like your tractor was available with either 2 or 4 wheel drive, both with diesel engines - if your "not a mechanic" status is TOTAL, the ONLY thing (short of breakage) that'll stop a diesel engine is shutting off its FUEL. Also, a quick look at your front tires should tell you whether yours is 2 or 4wheel drive; agressive tread will almost guarantee yours is 4WD, smooth tread should be 2WD.
BTW, google (in between taking over the world :=) can be your friend
hinomoto e16 manual - Google Search
A word of warning tho - if, in your search for a manual, you see one on disk,
make ABSOLUTELY SURE they include the word "SEARCHABLE" - there are quite a few of those offered cheaper (usually), and all you get is a disk with PICTURES of each page of a manual, in PDF format. "searchable" indicates they've actually taken the time to OCR those pics and convert to text - without that, you can search on ANY word and get a "not found", not a lot of help when you wanna know about "hitch", "transmission", etc...
'Nuther word of warning; this new "addiction" can be a pretty deep rabbit hole. I actually HAVE been a mechanic, and I STILL ended up with an entire 40" wide top and bottom rollaway tool box dedicated to large/tractor/hydraulic type tools, not to mention a few thou$and in machine tools - YMMV, but you've been warned :laughing: ...

Looks like Airbiscuit snuck in while I was typing - his pic shows a 2WD version; no such thing as too MUCH info...
