- I bought this b7100 tractor for $400 after being told that it ran a year ago, I felt pretty good about the buy. But after uncovering little hints of abuse while getting this machine going. We find out the truth behind the cheap price tag.
Kubota b7100 tractor case lawn garden tractor skid steer and tiller will it start? Major problems

The starter the real mvp here😂
My money is on a head gasket and a warped head, but I'd like to see a teardown video if you're up for it. Also, PLEASE do yourself a favor and get a winch on that trailer so you don't hurt yourself or someone else. That loading method was one mistake away from some serious consequences.
i would make sure no water is in the oil before cranking it.........
Of course we wanna know whether it was the head or block that cracked 👍
cracked between valves im sure.
FYI, when you're trying to turn over an engine for the first time, always take out a spark plug/glow plug to let out any fluid trapped in the cylinders before you crank it and possibly bend/break something.
I have watched many of these videos just to see his "F" UPS and HE IS MENTALY CHALENGED. HE will not take any advice from PRO mechanics . very sad.😭
@@thomasr.miller5553 Seems like offering encouragement, rather than put-downs could be helpful? Doubt anybody here, me and you included, haven't ever done something kinda dumb.
Young folk need to take an interest more in the mechanical arts, no need to shoo them away.
JUST keep watching and you will be amazed at how he gets away with applying the wrong techniques. @@3sparewashers-lg3gf
@thomasr.miller5553 I agree. He's what? 22 maybe if that? This generation already knows it all. They don't need advice from folks who have been doing similar things for decades.
@3sparewashers-lg3gf but they have to be willing to listen. This guy will most likely succeed but will end up paying a lot in "stupid taxes". I've paid a lot. He'll pay more. Good luck to the kid.
Way to go on holding your ground when ole boy wanted to up the price on you. What a Piece. ( him and the tractor)
Please take it apart and show us what was wrong. Im sure you can find a cheap enough engine to swap into it also. Or maybe a backyard rebuild
If you can get an engine for $400, I would definitely change the engine
Tear it apart and throw some JBWeld on it!
I dealt with a little kubota in a baby little thomas skid steer that the last owner blew a water pump belt and ran it until it locked up. I pulled the head found a good amount of visible cracks in the head i bought a china reproduction head and it was back to running good but did burn a tiny bit of oil. I'd yank the head see if the gasket is gone or the head is cracked then pull the oil pan pop the pistons out hone the cylinders with a ball hone slap new rings on it and I'll bet it will be a solid runner. I can't imagine the block being cracked typically they will push a freeze plug out or crack the exterior of the block before anything internal. The cylinders might be pitted up a bit though
Now you need Kubota attachments. Seriously, rebuild that little engine.
Put a 4 cylinder in it off a reefer trailer have a v2203 and makes 40 hp with a turbo makes 75 hp be cool and should fit if not then rebuild the 3 cylinder they are good little engines they run forever.
Stop never try to start it with out checking fluids and then try baring it over,if it is locked pull the valve vover and remove the rack and inspect things.
The way you did it was so completely wrong, I'm surprised con rods didn't come out t he side of that engine. Pull injectors, Marvel Muystry oil or ATF and brake fluid for a week. DON'T touch for a week! It will loosen the piston from the rings and the rings from the cylinder walls. The excessive blowby, could still be the rings. Definitely a head gasket for sure. Could be just the head gasket judging from the amount of smoke coming out of the upper radiator hose. Pull the head off. Do it slow and methodically. A head gasket for those little Kubota engines is cheap. I think it's still saveable. With a little patience and work.
His way of starting it may have caused the blowby. LONG pipe wrench is not the way to do it. He may have broken some rings and now it has blowby. He says it was abused and he is right. He abused it in addition to anything the previous owner did.
Engine had a chance before he just went to cranking on it
I run one of these in France, but 4x4 and manual. Built out of 3 scrappers and a 6000 head on a 7100. Might be just the head gasket, these engines do funny things but are pretty bullet proof. As long as the water pump, radiator and cooling system are all good, you might be able to use Red Hylomar to reuse the head gasket. Mine has run no problems for over 7 years doing that. These engines are quite easy to work on. Strip it and have a look, you might be lucky and end up with a good little machine.
You and the lil tractors brah
Full Rebuild!!
Probably cracked some rings when cranking on it to free it up. My guess the block cracked from the lack of antifreeze. You got yourself a parts tractor!
I wish we lived closer man it would be fun to tinker around and help you on stuff btw those hydrostats are a lot better than having a clutch, I bet u could swap the rear hydro to your other tractor. Those engines are really easy to rebuild but I do hope u make a vid tearing into it
an old trick is a heat gun to supplement hot air in the intake. also you have a bad valve- puffs of black smoke out the intake
Thanks
You should try to get the backhoe attachment for that one. After you get the rebuilt engine in it.
These old tractors usually you have to keep the glow plugs on for quite a while in between trying to start it do not kill that starter
There is no water pump on a B model ...
When you get that thing running you should drag it
Dang, that loading was quite sketchy, getting a winch is probably a good idea.
Sketchy is a characteristic of this channel that will not change.
Well, hitting the sketchy seller with loader bucket does reinforce the channel sketchiness for sure :D
@@BradenBuildz Needs the Shake hands with danger guitar riff 🤣

I just rebuilt a 3 cylinder Kubota engine pretty cheap for about $400. It was pretty simple, that would be my route if I were you. Mine had cracked pistons where the piston rings are.
YEA! open it up to see what did the damage..
A friend of mine has one of these engines in his boat, they are a stout engine, stout enough to push his trimaran along at a good clip.
Would have been interesting to see you strip it down in the same video, to make it longer.
You got to take it apart bro
Wow. Dishonest sellers suck.
If I might make a suggestion, it may be worth inspecting the condition of the head and block, see if it’s just a blown head gasket. It’s just a suspicion, but based on how low the coolant is and the fact that there’s no coolant in the engine oil makes me wonder if maybe this thing was just overheated and run dry, hence the swamp water, PO couldn’t give enough of a care to add actual coolant. I mean hey, worst case you’re just confirming the engine is in fact bad.
Sucks that little tractor was so abused. They’re really reliable when given a reasonable amount of maintenance.
Right. It’s not tired it’s just abused.
@@BradenBuildz , running it so long with no coolant is pretty good abuse as well.
@@nvrst this engine doesn’t deserve water
@@BradenBuildz Even before tearing it down, a potential test could be to fill the cooling system with regular water and let it come to temperature, see if there are any leaks. A hunch tells me this thing was leaking coolant quite profusely, hence the extremely low level. If it was leaking into the crankcase from say a blown head gasket or cracked passage there would be more coolant than that and plenty of coolant in the oil. Oil looks reasonably clean so no water probably, but cracking the drain plug isnt a bad idea. Just let a little leak out and put it back.
If you scrap the motor keep the starter. It’s a champ. Head gasket is blown. Replace and deck the head. It’s a tractor not a race car.
Do a teardown and see what was damaged. Its shot anyway, at least confirm your suspicions. Thanks.
Got it running well its over heated now for sure....keep running it so you can ruined it to make it unrebuildable
First. You should have gotten some oil in the cylinders and let soak for a couple days before trying to break the engine free. You very well could have broke a ring. Second use a little startup fluid and save that starter!!
Rebuild it or change out the motor if you can get one cheap
mechanic 43 years. ready to retire and working on these is what i will be doing and wood working!!! probably was rebuildable until you ran it that long?
Nah didn’t hurt it. Hope you can retire comfortably soon.
@@BradenBuildz well kid keep on keeping on. Its time we pass the torch. Good job!!!!
Cool video. I say Tear into her like to see the exact problem is. May be do a jb weld repair see if it runs again video.
pull the engine down just to see why it seized up. those are good little tractors and make great content. if nothing else re-power it and sell it off. Might only make a buck or two on doing that but it's better that scraping it. Good luck and great video.
Your "starts" are wayyyy too long, you will damage starter!!!! Why dont you use eather???????
Has glow plugs won’t start with out them. Ether wrecks Diesel engines.
Some folks are afraid of using ether. But WD40 works almost as well and much safer.
Well you certainly burned it up by running It Wide Open without any coolant!
thats what i was thinking
@@beesbo1856 wd-40 doesn’t work at all
Yea id say that engine is shot now that you got hold of it. That engine was fixable until you went on and did her in. Its possible the rings are stuck that is y so much blow by!!
starting fuel
Dang it that sucks
say goodbye to that starter!!!!!!!!!!!!!
Swap your engine and loader onto that frame. The HST is way more convenient with the loader than gear driven to operate
Yeah but only 2wd
@@BradenBuildz canˋt that be swapped also?
you have an middle (lower) pto… whats the ratio to the wheel rpm?
@@derlukec.8533 The mid PTO option is not 4wd interchangable. PTO spins at a constant speed, transaxle varies its speed by gear. Good thought, but not really practical. It may be better to swap the hydrostatic over aafter confirming its function. 4wd running driving loader tractor, and a 2wd gear drive which is the most ideal for drawbar type implements such as cultivators.
Air cooled !! Way to long running it with no water😊
Your loading abilities could use some help!
Definitely want to see a tear down video. I would give you your $400 back for that tractor.
Steam coming out of the hose from the remaining water boiling
And daddy's money spoke again.
Yep all $400 of daddy’s big money
You’ll probably get the 400 for the starter, some starter with the amount of time you spent swinging off it.
Hey ill buy the hood from you!
$400 for a parts machine is a steal.
I put that little tractor in a drunk yard oh ok.
I wouldnt complain much for 400 dollars, Here in Finland it would be 2000Euros for that
Plus the rebuild kits for these engines are not that bad either, I would rebuild it
Yes, it is shot!! If not for the blow-by, I would say gamble on head gasket. But with compression in cooling system and crank case…. Trash!!
You should have sold it for the $500!
I think you’re confused. He wanted $100 more than what we originally agreed to.
over-filled oil would explain it being blown out of the breather
Nope
Imagine how many people that guy has cheated over the years!
Fix it
Nice
first use starter fuild then turn the fucken thing of when you havent connected it to water
Tear it down let's find out what happened.
If you were closer I'd give you your money back for it.
Put another engine in it
Well if it wasn’t over heated before it is now
Nah. Youll know when something over heats. Either shut off and lock up or start knocking real bad and running slower bc the clearances are getting tighter.
@@BradenBuildz haha I hear ya still you don’t run something without coolant how long you did and at rev smh I build engines man bad form
@@devshewitt4809 I didn’t hurt it anymore than it already is. Everyone builds engines
@@BradenBuildz haha whatever you say dude diff is I do I’m not TH-cam builder
You might pull the head off and check and see if it has a blown head gasket. If you're lucky that might be all it needs. 🤞
Yeah possibly. We might have to tear it apart and look.
It might have been okay until you ran at Full Throttle for several minutes without any coolant. It takes all kinds I guess.
‘Might have been okay’ after having to crank on it for an hour at full throttle with hot glow plugs. Takes all kinds I guess.
@@BradenBuildz That starter is the most reliable part of the engine lol
People being cactuses in the comments. At least he’s trying, weve all done some things before and thought back like, damn, that was far from the smartest or easiest way. Offer constructive criticism, dont be a 🌵
Fis it.
It is a had gasgikt
Oh well. One cannot win um all. Nice try though.
A viewer has challenged me to say somthing positive . I dont usualy post comments .SO 🤔 READ THE SERVICE MANUAL.. DOING IT RIGHT COST LESS. Thanks
“I don’t usually comment” (has over 10 comments on this channel) appreciate you.
Shut that thing off ....longer you run it ,the more damage our making esp with no coolant
dude...lay off the starter man !!..you are going to burn that starter up !!..don't you know you are suppose to crank for a few sec's..then let the starter cool off ?..just..wow...lol.
Poor starter, was cool to see a kubota pull the other kubota , fix it and have two then start collecting them.
Fix it
