UP AND RUNNING! Bryco spot on company for gaskets and engine parts Mail order and quick. 

Heads checked , gaskets renewed . Rebuilt. Lawns mowed. Happy Wife. 

All in the world is well ...lol 

modified upto date head kits on the way. I believe the stress surfaces MUST be oil free.

Hayter ride on started smoking and burning oil so did a bit of resurrect as it starts and runs great. 

After a watch of good old You tube, a simple examination of the spark plug diagnosed a blown head gasket which apparently these engine are prone for.

Stripped it out this morning and  there it was ,blown from the cylinder to the oil return to sump gallery.

Kits  to be order Monday morning

Nice job well done

I thought of putting a seat on there . Do you think they would let me off with that .lol 

A little ride around in the sunshine . I didn;t get to drive I couldn,t get my son off the seat ..lol   3 acres of finish topping  with a  5 foot topper also rebulit. 

Cheep enough to have a go but balancing may be a issue . I think I would have a go 

Cracking looking machine . Should keep you out of trouble for a while 

Just a quick update. I have been doing some work with the Kubota and I have been watching the temperature gauge. 

First thing is I have fitted a variable speed switch to slow down the speed of the pump  as I found it was over cooling the engine. The I was struggling to get heat in the engine at all .

Running the pump at quarter speed and it seems to work very well. I have not put it under heavy load yet but it seems to be very efficient. I will keep you updated when I do some more testing, ( when the ground drys up ). 

Yes thanks for that.

I have not permanently changed anything. It was always a small fear that I could make it worse not better so it can always go back to standard. I have a good datum  for load and temperature . I will quickly know if it has been an improvement  or a failure. Later machines all have a pumped system which says alot to me  

If anyone knows the early kubotas they have what is called a Syphon  Cooling system. This means as the engine heats up , Hot water rises to the top and the cooler water after the radiator sinks causing a circulation of water.

I have fitted a coolant gauge and can see the temp in the top hose.

This works but i think it can be improved upon.

I have sourced a 12v electric  water pump and plumbed it in replacement of the bottom hose. 

Currently I have run the engine and watched the temperature rise without the pump running. Turn the pump on and the temperature instantly falls .

I have got a variable switch  to adjust the pump speed if it over cools the engine . I will have to wait until i can run it hard under load to give a full test and report.

The Farmers boy serial number 1178 , plough

Came across this machine languishing in a shed and was wondering what people thought? Is it desirable and is it worst anything .

Not my usual type of machine but it has been dry stored and will be a runner.

Not really the right time of year but i wanted to test the newly built engine under load so strapped on the newly welded finishing  mower and dropped it in. Chopping brush in a neighbors field  . Home made over head bar works well and somewhere to hang work lights . I wouldn,t call it a roll bar but it could only help.

fantastic job .looks Great!

Note to self Do a job properly! Found a damp patch under the tractor this morning. It could only be coming from one place. The core plug behind the flywheel. Up Side is I have got this splitting the tractor in half down to a quick job now.

WHAT A DIFFERENCE!!!!!! Picked up my injectors after being overhauled with genuine  Nozzles. less than 24hrs from drop off to collection Fantastic service. Fitted , bleed and fired up first time . No smoke and runs like a new engine .  

It runs smoother and cooler now . I think washing out the block helped.  Having a temp gauge now gives faith in what is happening. I will in time fit an oil pressure gauge. Now need a few fields to plough to bed it all in.

After a bit of running It still smokes badly on cylinder one. on start up also dosn,t sound as it is running on all three until it starts to warm up then all is fine . I have removed the injectors and had them tested today . I have replaced all three injector needles with items new from ebay. On testing all the  spray pattens on the injectors  are appalling . so New genuine needles on order and set up. Hope this will make things a bit less smokey.   

Cheers Useful Information. 

Hi all I am looking for a mower ,topper flail for a small kubota tractor cat 1 linkage  4ft to 6ft  . Not a million miles from the Buckinghamshire area.

Picture for reference only.

Well she drives again. It Appears I have a poor injector. Number one is smoke on start up but clears after a short time . Going to get them properly checked and overhauled but it will run and starts loads better than it did.

After tea I opted to drop the rad on and give it another run . With a few more revs and heat in the engine she ran up clean and smooth. I will see what its like cold in the morning and refit the front axle.

Shes a runner !!!!!! Number one is smokey .I think possible injector problem. I will swop  over cylinders and see if smoke moves.

crank in with new main bearings . Pistons and rods in all new bearings . flywheel fitted. I will hang it back on the engine now as it is still lift able at this stage

Block is back with new liners . Apparently it took all a 10 ton press could do with a hot block and frozen liners. once in then machined to correct size for standard rings. Quick coat of fresh paint and now start to replace all bearings.
