I have a 2016 Cub Cadet Pro Z 100S (steering wheel). It's a commercial mower with just over 400 hrs. One the tires has a slow leak. The other 3... have VERY slow leaks. The fastest leaking tire needs air about every week. The other 3... about every month. Given that the tires are 9 yrs old...

Mulching and high lift blades are opposites, other than they both cut grass. High lift blades are designed to cut and evacuate the grass from the deck as fast as possible. Mulching blades are designed to keep the grass in the deck as long as possible. If you're using a bagger, get high lift blades.

According to this video, I was adjusting the right screw for the high speed, but it didn't seem to have any effect.

Ok... I figured out how to set the idle speed, but not the high speed. The only adjustment on the governor assembly doesn't seem to have any effect. So I searched the engine manual. From the EFI SYSTEM section of the engine manual: Idle speed is only adjustment that may be performed on EFI...

That's what I figured. Thanks for the info.

EZT750-3011. Looks like 1500 and 3400. Thanks, StarTech. BTW, where did you find this? Is there a way for someone like me (non industry professional) to look this up?

I have a Cub Cadet PRO Z 100 EFI 154-S (53RWEFJA050) with a Kohler Confidant EZT750 (747cc, 27HP, EFI) engine. I recently acquired a tachometer. I'm not sure that the idle and running RPMs are correct, so I'd like to set them. Anybody know the specs? I found the following in the engine service...

I never said that battery mowers are underpowered. I said that mowers have increased in power in recent years, and that it's not a bad thing. If you have a non self-propelled 21" push mower with side discharge only, 3.5 HP is enough. I have one of those as a trim mower. If you want...

I don't live in CA, but up until the last presidential election, the government was pushing the green agenda, led by CA. Even outside CA, EV's have government subsidies. Have you been to a Lowe's or Home Depot lately? There are way more battery mowers on the floor than ICE models. The government...

That was when the norm was side ejection. I currently have a simple push mower with a 125cc Briggs 450E engine. That probably has around 3.5 HP. It's side eject only. But most people want to be able to mulch and/or bag. For that, you need more power. I DO agree that mowers have been getting...

The problem I have is with the mandates. I have battery hand tools. And a small battery chainsaw. Battery tools make sense in some cases. In others, it doesn't, and I resent the fact that someone is wanting to force me to go electric. I have a 54" commercial ZTR that I got for a great deal...

I have a Cub Cadet Pro Z 154S with a 27HP Kohler. When I first got it, it seemed to do fine until I got to the thickest part of my lawn. Then it would bog, and start smoking. Turned out to be clogged cooling fins. It was overheating. Since getting the fins cleared, it cuts through that thick...

I just bought a battery... chainsaw. For my wife. She wanted a chainsaw she could use, and she can't get any of my gas saws started. I think a small battery chainsaw makes sense for some jobs. If I'm bucking logs, though, I'm using a gas saw. For mowing, I'm firmly in the gas engine camp, too. I...

Sounds like a job for a respirator. I bought one for mowing. Certain times of the year, I find myself mowing through clouds of dust. I keep finding more uses for the respirator. Stinky and/or smokey environments qualify.

OK, but that RD weighs (according to Wikipedia) 342lbs. A truck weighs over 10X that. Although I have to say, that must be a VERY well tuned RD. My 4-stroke bikes never got mileage that good.

I've run lawnmowers for 35 yrs, and I've yet to shear a flywheel key.

Yeah, but they would get 3 mpg. :ROFLMAO: I've had good luck with 2-strokes. I raced 2-stroke dirt bikes in the 70's. Since then, I've had numerous 2-stroke trimmers, leaf blowers, chainsaws, etc. I'm just a homeowner, and I've never operated a 2-stroke engine commercially, but I've never had...

A bit of an update. It starts & runs MUCH better than before. I've been an Echo fanboy due to several factors. One of the big factors is that Echo's are supposedly easier to start. This saw, before I fixed it, was very hard to start. Now... it starts just like the manual says it should. It has...

The bolt wasn't broken. I stuck a thin spray tube down both holes, and they went to the same depth. I bought a couple of new OEM bolts. Stihl is proud of those bolts. $6 ea. I asked the parts guy what thread it was. D5. Some Stihl specific designation, I'm guessing. That's not SAE or metric. I...

That's possible, but I don't think so. The bolt goes in, and slowly gets tighter. If there were a broken bolt in there, I'd expect it to go in easily, then hit a hard stop. I'll check tomorrow.

I recently took apart my Stihl MS 192 TC chainsaw to clean it and rebuild the carb. I found that the muffler was completely loose. I found one of the two bolts needed. I reinstalled the muffler with the one bolt, and cranked it to see if it made it quieter. IMO, that saw was way too loud for...

Thanks StarTech. That did the job. That carb was a bear to get off, though. It was stuck on there quite tight. I've never pulled a carb on one of these saws, so I wasn't sure if I was missing a bolt, screw, etc. After getting everything back together, it wouldn't crank. I thought, oh, geez, what...

Neither have I. I suspect that mowing business that handles hilly properties would use a 4x4 mower of some type. The SW ZTR's, IMO, are an improvement over lap-bar ZTR's, but probably still not good enough for serious hills. My Pro Z154S works great on my property, with it's moderate hills. The...

A steering wheel ZTR will hold a slope much better than a traditional ZTR with lap bars. I have a Cub Cadet Pro Z 154S. I found it cheap (it needed repairs), and bought it to replace my lap-bar ZTR. The CC had numerous benefits over the mower it replaced, but I bought a mower with the steering...

I have the above top-handle saw, and when it runs, it works great. But it's been getting more & more reluctant to stay running. I'm almost certain that the fuel diaphragm in the carb needs replacing. It's acting like it's starving for fuel. But I can't find a parts diagram or parts list with...

IMO, the engineers who designed the engine know more about what oil is best than any shop owner. Also, most engines that die from oil related problems do so because the oil never got changed. So the mfrs are probably recommending the best oil for their engines, but these engines are notoriously...

I'd be ESPECIALLY irritated if I took good care of my equipment, and it still died in 3 1/2 yrs. Worthless warranty... obviously not Echo then. Was your crappy gas equipment from one of the big three? Echo, Stihl, Husqvarna? If you had cheap gas tools, I'm not surprised at the problems. If you...

Well, yeah... that IS great customer service, but... I'm not sure I'd be pleased if my 3 1/2 yr old trimmer needed a complete replacement. I have two Echo PAS systems, both of which are over 10 yrs old. Not a single engine or attachment has needed replacement or repair. OK, except the trimmer...

But you can trust a cabal of pedophiles? Pedophiles should be slowly tortured to death.

The old flathead engines have very low compression. The new OHV engine have higher CR's, but I don't know what they are. If I were making E0 for a flathead, then I wouldn't worry about low octane. Not sure if that would work with an OHV engine.

Ethanol is an octane booster. Removing it lowers octane. So if you do this, start out with premium (91-93 octane) fuel.

The video has been pulled. See Taryl's response/reasoning: I Felt It Was The Right Thing To Do

I have a Pro Z 100S. I think it's a 2017 model. I bought it used. It had been used commercially, and used hard. It had several problems when I bought it, but steering wasn't one of them.

I'm in this boat, too. Several years ago, I bought a 2000 Ranger for $1000, and it was a basket case. It needed work on: engine, transmission, suspension, brakes, A/C, radio, window and door lock switches. I put about another $1000 in it, and it runs, stops, and steers like new. Still looks...

I have two push mowers. One has a paper filter, one has foam. The new small Briggs engines without chokes... have foam filters.

I'm negative on battery powered OPE because it's being shoved down my throat. As are EV's and other "green" initiatives. Battery tools are fine for light duty. In some cases, they are easier to use. Like impact wrenches. I was recently at a Discount Tire, and got a look inside their work area...

What kind of filter are we talking about here? Paper or foam? If foam, are you oiling it. A dry foam filter will let dirt by.

I may have to keep an eye out for a good deal on one of those. I really would prefer a lap-bar ZTR, but my steering wheel ZTR just works SO much better on slopes and hills.

While you're certainly entitled to your opinion, I strongly disagree. I have a steering wheel ZTR and a "real" ZTR, i.e. one with lap bars. The slope holding ability of the two are not even close. The one with the steering wheel is much better. The lap-bar machine wants to slide down a hill if...

Why not go with a lawn tractor? I have a Cub Cadet steering wheel ZTR. It's main advantage over lap-bar ZTR's is it's slope handling ability. Lap bar ZTR's don't work well on slopes. So since she has such a ZTR, I'm guessing her yard is fairly flat. If I were mowing nothing but flat areas, I...

Sounds like a problem with the auto choke. I have a similar mower with a similar engine. There is an air vane that actuated the choke. There is a spring on that air vane. The spring on mine went missing, and I had the same symptoms you have. Well, almost. I could start it without starting fluid...

You know... I wouldn't even be mad.

I was a skinny teenager at the time. "super fast ramp speed Dyno Cams"... Nope. I think my "career" was before those. Late 70's. Most of the aftermarket engine parts were Horstman.

Where did you race? My dad and I built and raced WKA stock & modified using Briggs 5HP flathead engines. We raced in upstate SC and western NC. I re-set the lash on the modified engine after every race, and we raced weekly. I can tear down a horizontal shaft Briggs flathead in my sleep. I'm sure...

I wouldn't pick Clinton over ANY other choice.

Sorry to hear that. Startech was one of the most helpful members here.

Have you tried removing the gas cap? The symptoms point to a possible clogged vent. Some caps are vented. Some vents are in the tank.

What kind of mower is the Bolens? Zero turn? Lawn tractor? How well does it handle the inclines? Do you need better slope-handling, or does the Bolens work fine on the inclines? If you need better slope handling, you should consider a steering wheel zero turn, which locks you into Cub Cadet...

Doubtful. I don't recall... have you checked the flywheel key? Backfiring would make me suspect the key.

Have you cleaned the carb and tank? I had a problem something like this with one of the newer Briggs with plastic carb. It would run fine, then act like it was out of fuel, sputtering a bit, then dying. I cleaned the carb. The bowl had water & lots of trash. I took the carb apart, poked wires...
