I have easy to follow and thorough step by step tutorials "do it yourself" (DIY) videos to help you with your broken lawn and garden equipment including snowblowers and zero turn mowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed whacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, zero turn mower, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on KZbin and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

I own a X300 and blew that part from jump starting the battery for a few weeks.

[@georgeian3243]

Thank you, good to know. I had (have) a problem with my JD X300 where the engine dies after a few minutes of operation, starts to splutter like its running out of gas. After resting for about half an hour, it starts up and runs again, usually without any more trouble. This would happen on an irregular basis...I removed the carburetor and cleaned it out, changed the plugs, cleaned the air filter, but no difference. Then, one time when it quit, I got the idea that the fuel filter might be plugged even though it was also new. This time, when I removed the hose from the gas filter, I heard a suction sound like air rushing though the hose...I had a vacuum in the gas tank. I think my gas cap vent is plugged and the vacuum prevented fuel from flowing to the carburetor. I should replace the cap, but I haven't so far...whenever the engine starts to splutter, I loosen the gas tank cap and it starts working properly again. Have you heard of this before?

So that's 17 yrs. old and 740hrs. mowing around a bunch of stuff on the farm without a scratch on it. Just bought a 2007 LA150 and the hood & dash are in great shape also.

[@beachbums2008]

Is a booster? Jump pack,battery, charger??? Inquiring mine would like to know. Thanks in advance sir

[@smegheadg]

A booster pack is generally a device that can throw an extra power load to your onboard battery through an external connection. Some of these devices are just plain boosters, some are large battery charges that allow you to send extra amps to your battery to try and jump start a dead battery immediately.

[@WJCTechyman]

Well, if small engine technology kept up with automotive engine technology we would have more efficient, and thus more reliable engines. It did wonders for cars. Most cars built before fuel injection had a tendency to break down, and now you have cars where most of the time taking it to the shop is changing the oil or working on other issues not pertaining to the engine.

[@richardwernst]

@@WJCTechyman I disagree entirely. I know many, many folks with newer cars full of electronics that require extremely expensive diagnostic equipment, not to mention subscriptions to services with all the latest info, tech, recalls, updates, etc. for all the models, who have had nothing but headaches getting their cars fixed. One friend still has her C-Max that randomly will NOT turn the radio off when the car is shut off. Several trips to dealer have resulted in no fix other than to "disconnect the battery under the hood" to stop it. Her fix, courtesy of me, was to find which fuse the radio is on, and keep a puller handy when it happens to shut it off. Or my 2017 chevy where you cannot turn the radio OFF (although it does turn off when the car is off). You have to turn the volume all the way down instead. While fuel injection on cars is amazing at the mpg and lessening pollutants, it too is a real headache when it's not working right, from having to have TWO fuel pumps (with on IN the gas tank and on many models you have to remove the tank entirely (often quite an operation in itself, including having to drain most, if not all the gasoline), to a minor electrical problem stopping the vehicle entirely. Don't get me wrong, the current vehicles are amazing items of technology, but the complexity doesn't make them "better". Taking the lead of gasoline inproved engine longevity a HUGE amount, not some special tech solution. As for my lawn mower engine, it's probably over 30 years old (flat head briggs and stratton), it still works great, starts after a pull or two. I have a very small lawn and really don't want to spend $400+ for a battery one where the batteries (lithium) are a cause for pollution and huge energy requirements, but disposal is also an issue. I use a plug in electric weed wacker for getting edges, etc. cleaned up.

[@jimbrewer2893]

Jumping car batteries is a not recommended as well. ECMs can be a real challenge to troubleshoot. Great information.

[@TheTronder007]

When I took delivery of my new car in 2017 the salesman at the dealer explicitly told me NOT to give or receive jumpstarts as the consequences could end up being costly as it cold cause damage to the (many) ECMs. Using a start-booster pack with an on/off swich that is connected and then turned on would be safe for the car.. This might based on what Dony said not be advisable for a ride-on mower though..

[@100vg]

I don't have a John Deere, but I'm sure my Troy-Bilt and Craftsman lawn tractors have a similar device. What do you mean by "Boost" it, please? A specific kind of Charger, high charging Amps or what? What year was this new controller module implemented, please? My Craftsman is a 2007 model and Troy-Bilt is 2011. I use a battery maintainer that only gives like a 2.5A Max (or less) at first and then trickle charges once charged to maintain the charge. I haven't had to use it with the new 350 Cold Cranking Amps battery I bought. It had a 230 CCA battery (like I see now the manual says at a Minimum), but it wouldn't charge, so I bought a 350 CCA for less battery strain and hopefully a longer-lasting battery. I bought it because it was hard to start, but I fixed all of that with a new carb (lost internal parts, so I was afraid to rebuild), a breather hose, some other parts and lapping the valves, so now it starts easily and runs great again. Now I'll only use the battery maintainer during Winter storage after Winterizing first, but I'll have it if I need it. Thanks for all you do, Don. I might have found the controller module the hard way, not knowing it had one.

[@gregoryking9348]

It's a potted assembly so the electronic components not only can't shed the heat they may generate; or are subjected to by the engine, but the components that don't generate heat and are sensitive to heat are trapped. It's a logical build method for electronics that are exposed to moisture but as with everything these days the components are sourced based on price more over quality and longevity.

[@WJCTechyman]

@@gregoryking9348 So? Do what auto manufacturers do and make the casing out of cast aluminum with dissipation fins and pot the electronics then. Heck, even inverter generators for the computer and supporting hardware is made this way. These machines are expensive enough to warrant that. The voltage regulator on my Kohler engines are made this way.

[@jamesgreene4554]

Does stihl have something like that on their newer chainsaws? I have a MS661 that does the same thing.

[@941Earl]

Pull your muffler and look at the piston, rings and cylinder walls through the exhaust port. If you see scoring, then your saw probably has compression issues and needs a new top end. Starting when cold, and then lacking power and stalling once hot is a common symptom for bad compression. The saw usually wont restart until it cools down. Once cool, it will start and seem fine until it heats back up again. Just something to check!

He's talking about a Battery Charger with " Boost " setting...a Jump box is just another battery that has enough voltage and amperage to assist in starting a weak battery....boosting by using another same voltage battery and jumper cables is safe too.... boosting ( jumper cables ) from a running vehicle is normally ok but shutting the good vehicle off would be safe.. it should be ok when running but voltages could be higher ( although 99.9% of the time it should be ok )... basically a " Boost " setting on a Battery charger is what he is saying is what i believe what he is concerned with.... i been fixing vehicles for 50 plus years..

[@garymallard4699]

And trying to recharge a weak or dead battery is always a safer way to get a vehicle started.... in all cases.... using a good charged ( or at least close to fully charged ) battery and battery booster cables is 100 % safe on any vehicles....i try to start charging to at least give the dead battery some voltage up near 12 volts and check the bad battery before boosting it... nowadays i use chargers that give me some testing or diagnose and have hand held testers too...and Jump packs nowadays are simple ways to get a vehicle started enough to move or start testing the charging output or " home " lol

When you turn the key to ON you should be able to hear it click and if you are touching it, you can feel it energize. I have cleaned mine with a spray foam electrical cleaner (ZEP) that works very well. Someone has really abused that X500. X models have a totally different deck suspension and make a beautiful job of cutting on uneven ground. Actually made by JD I have heard.

Wish this video was out a couple years ago.. I fought this for a year, replaced a bunch of parts finally gave up sent it to dealer and they replaced this part.

That broken hood is why I am not too fond of John Deere's choice of plastic for body panels. When it's brand new, yeah, you can drop a bowling ball on it and it won't dent but after a few years and you do the same, this is the result. To add insult to injury, these plastic pieces, from what I heard are incredibly expensive to replace. Metal is something that you can at least work out and re-paint if necessary. I'm not really a fan of other things Deere has chosen for its tractors as well, but that's a different story. I find it interesting that a some of these tractors can't take a booster pack (even the Noco ones?) as they have the same voltage. If you can't boost them, how is it you can disconnect and reconnect the battery?

[@johnkosheluk1041]

But how do you find that out that sounds like a coil to John deer junk

[@barrylee.freedman2203]

You constantly remind me how glad I am that I don’t have a riding mower / zero turn from a big box store. 2nd thought, I suspect many of these are bought by folks limited by a budget who wind up with expensive surprises like plastic transmission housings, fake overpriced oil changes and cheapened internal engine parts. Doesn’t seem fair what happens to these folks who put their trust in a big name.

Don, looks like he rolled it down a hill sideways 😅

[@eosjoe565]

Current U.S. price is $110. The Technical Manual has some tests you can run on the unit but more often than not they are intermittent like the one you had and you end up just doing a swap-out and hoping that was the problem. Like I mentioned elsewhere, the newer models no longer have a separate control box, it is integrated into the LCD instrument panel and the replacement cost is over $350.

[@buddyboy4x44]

Good reason not to buy John Deere.

[@eosjoe565]

@@buddyboy4x44 I'm sure there are other manufacturers who use similar interlock modules.

[@jamesc9327]

Unfortunately 90 percent of the John Deere garden tractors you buy at the big box stores are garbage and don't last. For one reason or another we live in a throwaway society. It's sad when great mechanics like Dony have to work on the garbage that these companies are putting out.

[@Chris-Fennimore]

Yep, I have replaced it on my neighbor's John Deere.

[@philliphall5198]

First Cool 😎

[@mikedee8876]

I would be thinking about bypassing that unit someway somehow....fuel and spark delivery used to be controlled by more reliable devices, and if those devices are re-introduced one can cut out all the expensive electronics....no?

[@crabcake43011]

DIYer that fully understands and accepts their own actions- absolutely. Pro repair- no way. Stupid general Public + Creative repairs = Liability and lawsuits

[@Darth_Sidious_66]

I didn't have this problem but my washing machine had a F02 code. I cleaned the drain trap and it went away.

[@crabcake43011]

Don’t you just love that you need a scan tool for your toaster these days? Ok, maybe that was a bit a of a stretch, but geez, what ever happened to KISS? Seems like too many things are overly complicated simply because they can be and don’t offer a technological advantage. EFI on small engines-yes, it offers better efficiency and emissions. microcontroller based interlock- No, can e accomplished by simple switch logic.

[@Darth_Sidious_66]

@@crabcake43011 Exactly! Everything has a dang chip in it.

[@IIWII9]

Can you relocate the new module to a cooler location?

[@donyboy73]

You probably could by extending the wires.

[@PatHiggins-Mayo]

Does the driver own a labrador and a white stick 😂😂😂

[@BigDaddysGarage]

is it ok to trickle charge them??

[@donyboy73]

yes.

[@BigDaddysGarage]

@@donyboy73 Thank you for the response. Good to know!👍

[@boonecountygenerators3052]

I would be real hesitant to spend $100+ without knowing for sure the unit was bad. There must be a more definitive test you can run on the old unit for a more positive diagnosis. No doubt it's in a Deere service bulletin somewhere.

[@bobmcl2406]

With intermittent electronic problems, usually there is no diagnostic that will catch it.

[@georgepruitt637]

And "Deere" isn't about to tell/show you what is wrong or how to ck it.

[@philliphall5198]

So there trying to keep you from bypassing safety devices maybe Thanks for the advice and information Price of the unit is $$$ ???

[@donyboy73]

$150 in Canada

[@tlm3574]

Your customer needs to put a $27 Deere seat cover over seat.

[@timwolfers7880]

Part is $90-$110. 😮

[@andrewmunchkin7212]

I always use junk like those modern tractors as a saw horse.

[@antagonizerr]

Amazing how a part that a lawntractor doesn't even need can cause so much havoc but that's John Deere for you. Personally I'd bypass and delete it the first chance I get.

[@gregoryking9348]

That can be done of course, but without having a schematic of the components in that module (which is most likely unobtainable) you'd have to reinvent the wheel to emulate the same functions as the module. It appears the module's primary function is to coordinate multiple safeties. It sucks to be forced to pay that much for a replacement module but better that than possible injury or death.

[@auskip07]

what lawn tractors have this part?

[@steamboatwillie935]

X300 & X500 series tractors.

[@RussellBooth1977]

I would rewire it as if it was an old lawnmower if the module became NLA,it sounds like they want you to throw the lawnmower out when parts like that module become unavailable !

[@crabcake43011]

Fully agree from the home repair aspect, but liability for a pro repair shop is too great. Especially the safety interlocks.
