I just picked this up a couple days ago, I was lost and spotted it under a tree, went home and thought about it then went back the next day and offered to buy it and got it, its in good nick under 300 hours on the clock, I think it was parked because of an exhaust valve problem, the valve is totally stuck now and moisture has gotten down the exhaust.

 

Seems to be a pretty neat tractor, it has 2 fuel tanks one for kerosene and one for gasoline, and a very strange carburetor, it has a hydraulics and a rotary hoe.    

 

I am trying to find a manual and somewhere that sells parts,  I need a gasket set as I will take the head off as I need to deal to that exhaust valve

Looks like a interesting tractor. I Google it and got quite of few hits.. Not sure if they are all helpful but might learn a few things..

There was even a guy on GT talk a couple years back talking about one. Good luck with it. Looks pretty cool..

I think Hinomoto made small tractors for Massey Ferguson, I could be wrong thou.

Nice find it has some serious tires of the back wheels

Neat little tractor.  Probably a dealer around some place, just takes time to hunt them down. Good luck with your project.

Pretty sure that is a "grey market" tractor. Note the "RICE" tires that were used in farming rice in paddies. Had a grey market Shibaru and it worked well. They were all imported used and parts can be difficult t o find.

I am in Newzealand witch is about 90% farm, small tractors are worth a lot of money here as the people in the smaller Pacific islands want them, I can 100% say there are no parts in Newzealand, everything I have ever owned I have had to get them from overseas, 

 

 

I got the engine turning over last night but the exhaust valve was still a bit sticky, the sparkplug was so tight and when I got it turning it was cross threaded by the last owner, I will put a Hellicoil in it and I am going to remove the head as I think I need to clean and hone the bore and check that exhaust valve and seat, but I cannot find a head gasket, my wife is japanese ans she had a look on the net in Japan but sed its long obsolete.

one cool thing the cylinder barrel comes off the block like a motorcycle, you don't need to strip the whole engine to remove the piston.

I have removed the engine and taken most of it apart, it was full of water and rust, water got down the exhaust and into the cylinder and then down past the rings.

 

Most of the rust wipes off with a rag so things in the bottom end are ok, cylinder is ok but has some marks from where the rings sat, cam shaft is mint, just had soft brown powder on it, 

 

The exhaust had rusted out finally so water would of stopped getting in when that happened, I got the exhaust valve as straight as I can, I will get it ground and the valve seats cut, clean up the cylinder, the main bearings are the same as a Kohler K321 they are cheap enough so I will just replace them as they have some water marks.   

 

 

I hope to reuse everything even the head gasket as I cannot find any parts, I will make new cylinder base gasket and side cover gaskets.

 

Condenser is behind the flywheel witch took alot of work to remove and I think its bad, I am going to move it to the outside of the engine so I can use the same Bosh .22 Mf condenser I use on everything elce.

I need to fund a Hinomoto MB1500 Workshop manual badly, dose anyone know of one online?

[SOHC]

I have the PTO apart as it was locked solid, it had a rust hole in the cover witch I have welded up, the bearings are locked solid, I had to make a jacking plate to get the cover off the shaft it was so seized onto the bearing.

Glad you are making some headway! Good luck with it!

I broke the oil ring but found Toyota 11B oil rings are the same so have fitted one of them

Someone send me a PDF for 2 manuals for the smaller MB1400 if anyone wants the files I can send them to you, they were very useful for rebuilding the engine witch I have done now, I need to un seize the clutch, I hope its in usable condition and the bonding is still good if it is bonded, and rebuild the carb, the carb has a diapram in it witch I may need to make if it has gone hard.
