I had a red antifreeze in the radiator and i haven't change the fan belt since i bought the tractor.
so since i remove all the thinks i clean the block and the radiator inside (i pressure wash it and the to remove the water that was in it i fill it with antifreeze and water until green stuff start to come out the holes),i paint everything and change some bolts with new ones, new tube for the whistle and clean it to look line new, i even paint the exhaust with 2 layers of high temp paint.

and then i fill it with a premixed Green solution of antifreeze

the photos are here...

If my tractor happens to run away for awhile I won't mind if it shows up at your place at all Of course that is unless doesn't head back home when your done.

I don't mind to wash it and take care of it.

The problem is that i don't have the free time.
im 33 years old (at Greece the things are difficult) and my job don't give me the free time to play with my tractor or with the other things that i have here in the village,

im a computer and a network engineer, i work for some companies that need my services 24/7, i love the life at the village and i try to play every time with the bota.

Default Re: zl-1501dt things i've done

free time today and a good weather so i remove the Glow plugs to clean them with the metal brush and test them,




i measure the time that they need to glow really hot at strait battery to 20 sec.

so i decide to bypass the indicator the text time that i will find time, because with the indicator they need 43 sec.

or i will sit and think what needs to be done and make the glow plugs faster.
does any of you have some other idea?

The indicator is part of the total resistance in the circuit - thus it changes the voltage and current along WITH the two other glow plugs. Most indicators are simply a wound wire that gets hot and glows along with the glowing of the glow plugs, by bypassing the indicator - you are simply placing more current to the remaining plugs. YOU could bypass ONE of the glow plugs and that ONE would get hot in less than half the time!

The glow plug indicator is a simple design to let the human "know" when the plugs were hot!

Now days that is not the case - a circuit is constantly measuring the total resistance as the plugs heat up (once they start to heat - their resistance go up) and once it reaches a desired resistance - a idiot light comes on or off and tells the operator that the plugs are ready.

If you are the only operator - you could simple bypass the indicator and install a "momentary on" switch - or better yet a relay that can handle that total amperage, and count to "20" and let go!

I know that is part of the total resistance in the circuit and that's why i need to bypass it, its really slow


i have tray the glow plugs at a battery strait and they are getting really hot after 20sec.
now as you said im the only operator and every time i need the tractor i hate to wait 60sec when we have 0 Celsius.
i try to make the kubota better,

i will bypass the indicator if i think how to make it look and function like the original and i will post if i like the result.

on the "back" of the indicator .....there are two posts? Yes? Place a large wire across the both of them, now you have bypassed the indicator, you have now wired it straight! If you ever sell it, just remove the large wire.

And 0 c......hell - that would be warm around here! It was -17 c here the other morning as I hit the glow plugs for 60 seconds!

And the guys up north would love to see -17 c ! They might go out in shorts.....ok ...maybe not !

yes that's the trick with the cable back of the indicator that i have think about.
-17C, and only 60sec.
is your tractor out to the cold?
how many rotations the engine take before it fires up and working normal.
because i keep the plugs 45 to 60 sec at the winter and the small beast fires without hick-ups.
just i touch the starter and fire up
and don't forget that i have only 2cyl and this old puppies love the chamber really really hot.
