It almost sounds like they used superglue to assemble that coupler. I’d probably stick it in a bucket of boiling water to see if that would free it. I really wanted to see that machine running, but I get that the customer is waiting for it and you have to send it, plus I’d guess it takes at least two people to operate safely. Is it operated from some kind of suspension equipment like a gantry or tripod?

That’s one thing I like about your videos, the attention to detail. I look at the ends even on a string trimmer.

Will those harbor freight viton orings work on the other jet

Thanks for the tip

I have a 61 inch Bad Boy zero turn. My covers are held on with a knob on each side. They already have a gap at the bottom on the outside edge from the factory but they would sometimes clog up like this while i'm cutting. I took them off and cut 1/2 inch off of them at the bottom all the way around and put them back on. My outer pulleys obviously stick out past the foot rest on the mower so i didn't want to remove them. But now that i've done this they rarely have anything stuck in them and when i'm done cutting i can easily either blow what little is in there or rinse it out easily with a hose. Works perfectly and still keeps you protected in case you step off the mower before the pulleys stop rotating completely.

Do you have a video on how to replace the arbor? I didn’t know you could do that

People that don’t clean the grass around the spindles on the deck are so fucking lazy. I always leave. The spindle covers on. I take the spinner covers off clean the grass out of it put the spindle covers back on. It’s easy task if they’re too lazy to do it they’re so fucking stupid.

I have this set and love it 😍

sorry buddy but I think you are wrong.

Really good point, Warren! If the arbor isn’t real bad you can use a cold chisel filed correctly to swage the metal back into place so the blade will fit again. I’ve done this once so far and it only took me less than ten minutes. I discovered that technique from Russ The Deck Doctor. He’s the best mower deck channel I’ve ever found.

Oh dang! Just when I thought the stickers were an easy way to find part numbers! 😉 I’d probably cross out that number and write the correct one just above the sticker with an arrow to it so years down the line there’s no confusion.

I wonder about cutting slots into the covers so it’s possible to blow them out but still keep them in place, especially the metal ones on commercial units. Either that or fabricate some kind of tool-free system for covers so they’re actually designed to be quick and easy to remove and install. Any time I come across an engine shroud with through holes for the fasteners I get out the angle grinder and cut slots so the next time all I have to do is loosen the fasteners to remove the shroud.

Hey, Warren! Good to see you again - this time with 4 videos! Wow! 😂 I doubt I’ll ever see one of those in my shop, but interesting just the same. I fault the designers on this one. There should be some kind of sacrificial part like a snowblower shear pin instead of an actual gear which requires takedown to replace. I have every confidence in your ability to actually fabricate a collar with shear pin to make this machine more efficient and easy to service in the field for the operator instead of having down time in a shop. I’ll bet oil fields have sacrificial parts on drilling rigs for this exact purpose.

My 2015 BB mower with a Kohler and a muffler like that didn't overheat, BUT my hydro reservoir melted down twice and makes me wonder if it might be the engine getting hot. Interestingly, both times happened on the left side reservoir

I’m glad you added about the safety part. Mine are in the open. What I did was use pex water pipe. Then cut short lengths and put the bolts thru them. They compressed but left an opening at the deck. I can easily blow out the grass.

Thanks for the information. Don’t see you very much. I don’t miss one. Take care.

The first thing I do is take off the covers and throw them away.

Very helpful thanks 👍

Plain and simple explanation. Thank you

You sir, are my hero! Your tip worked perfectly.

My 75755 brakes dont always stop the mower.from rolling. Even if i turn the engine off, it will keep rolling. I live on a hill so it is a pain keeping it sideways on the hill. Would this be a brake module issue? It seems like it always moves the brake rods but the brakes inside the transmisson just dont catch. Half the time it stops like normal though.

so....bad fuse? How about everything looks perfect, but weathered...I get no click...nothing...Fresh battery, carb, connections, fuses etc...Thinking handlebar switch or jammed up at the flywheel w/ gunk as research has shown....This video did not help. I wish my problems were simply a bad fuse. Will keep searching...at least show it running and the fix.

Thanks for your video, just bought this kit. Going to use it for automotive testing and diagnostic work.

I installed a new kit including new needle and lever. The lever was not bent properly. Chainsaw not run. I usually just do gasket changes that work well. I should've left the old lever in there. No gauges. Will try to match surface.

Foam filter is missing.

Good vid

Excellent video. ALOT of ppl omit or don't even know about this step. I grew up working on tillitson carbs alot so have much knowledge on this...and you are correct if its not set right can drive you nuts getting it to run properly. Bill

I’m a small lawn mower repair person, why is it some carburetor it’s impossible removing the screw before the main jet… I have a special flathead that fits inside perfectly but for some carburetor you can’t turn to loosen the screw …

I found that this engine will not idle correctly if you do what you did. Maybe I missed something, I don't know. But my niece had a Graverly HD with the Kohler 7000 series motor and it would not run or idle correctly by just leaving the air vane on. When you idle it down the flap will go down and the engine will run rich because the air vane isn't keeping it opened up enough. Kohler makes a manual choke kit for this and it comes with a new carburetor, speed controller, wiring harness, choke linkage and oil sending unit. I put this kit on my nieces mower and it works fine. You will have to buy a choke cable and mount it on your mower somewhere, but mower runs just fine now. th-cam.com/video/eA0_nQlU6Bw/w-d-xo.htmlsi=f61q1Jw4iJwAONKn

My 4-wheeler would shut off randomly and lose all power. Ended up being a lose battery terminal….🤦🏻‍♂️

Setting up a predator 670 on my sp-H stumper, it had a ch20 kohler with a toggle switch, so the wiring plug for the clutch connects to the harness that leads up to the ignition clutch switch and fuse, Can I basically by pass that if I hook it straight to the battery, the only difference will be that the machine can be started with pto on or off, on the old set up the machine can not be started if clutch is engaged and idea or help would be great

TDC is your friend before and after.

I have slammed the carb body face down against my bench and have made the check valve work again.

Seeing this helped me troubleshoot my own failed starter system. Thank you

great !!

Thank you I spent hours trying to find a diagram 🫡

Just picked one up, as always i like to test for continuity before using and uhh mine was faulty went back and got it replaced

Great information. However, your video sucks by buying the equipment you need....

Thanks for the video.

So much useful information here

That jumper cable method while using those automatic sensing chargers was a life saver.

I thank you, I want to make a few of these to scare deer out of my garden and keep them from my plants.

Thanks so much! Have an old victa rotary how that needed a spring repairs.

Same issue with mine

Sheesh! Yet ANOTHER way for gas to find its way into the crankcase! Just when you think you’ve seen it all! Great diagnostic Warren. Thanks! 🔧👍

You always have the best info! Thanks so much.

Thanks mate

Great information. Helps us when looking at our issues.

Why is there adjustment in the back for the left side only? This takes stupidity to entire new level. There HAS to be adjustment for the left and the right sides, like they have on John Deer mowers for example. With this retarded design, yes I can move the left rear side of the deck up and down, and have it match the right side in height...but what if the right side is incorrect to start with? What if I have to rise or lower the right back side, to equal the front side?

Well THAT was easy! Thanks, Warren - another one filed under Diagnostics; Electrical for future reference. 🔧👍 Just out of curiosity, is there a dependable way to bench test the regulator itself?
