Toro Walk-Behind Lawn Mower: White smoke and spitting oil?

Mon, 07 Jul 2025 09:30:23 -0700

I shouldn't be allowed to operate power tools anymore, but whatever... I was mowing my yard when I hit a piece of hidden wood. A piece of wood jammed against the side of the lawnmower and the blade, which required me to flip it on its side and dislodge the chunk of wood. After I removed the wood, I put the mower back into its right position and took a break (It's hot out..). After my 45-minute break, I went to start it to finish cutting and it was belching out white smoke, and leaking and spitting oil out of the muffler. My father and I took a look at it finding nothing, but I took off the air filter cover and there was also an oily residue in there, more than normal. What could be wrong with it?

P.S: Comment if you want pictures.

Toro Walk-Behind Lawn Mower: Why does it stop running after 15-20 seconds

Sat, 17 Jun 2023 11:17:46 -0700

Replaced a worn fuel line. Ran great for about 20 minutes, then stopped. Will re-start but only run for 15-20 seconds. I replaced spark plug and air filter as well, but same problem. Engine keeps stopping after 15-20 seconds.

Troy-bilt lawn mower: Mower will not engage - wheels do not move forward

Fri, 15 Aug 2025 13:49:25 -0700

My self propelled mover is a Toy Built 22", 5.50 horsepower, Briggs and Stratton 550 Series, 158 cc, Model Number

12A-264U011, number directly the model number is 303526.

I changed the height of cut today, started the mower, engaged the self propelled arm and processed to cut grass. The mower moved forward and cut about5 feet, then all of a sudden just stopped moving forward. I released the arm and engaged again, the mower moved forward under power, then stopped again.

Can you tell me what to look for? I did note that the line that is attached to the forward motion arm is a bit loose, that is, it has some slack in it.

This has been a great mower. I had it exactly one year and 3 months. I purchased this mower after my husband passed and needed something I could handle at the old age of 70.

Awaiting your response.

Toro Walk-Behind Lawn Mower: smoke and oil coming from Toro variable speed propelled mower exhaust

Tue, 17 Dec 2013 12:52:53 -0700

I bought a new (customer returned) mower from a salvage dealer. It has never cut grass as below the deck is pristine. I added oil and gas and it started on the second pull. It pours smoke from the exhaust as well as spits oil (maybe oil vapor) that gets the deck and wheel oily. I saw one expert said oil in the cyllinder can cause this. Even with a new mower?

One other said to let it run for 15 min to burn it off, safe?

Any suggestions are welcome.

Thanks Tim G

Toro Walk-Behind Lawn Mower: Time cutter 4200 blades will not stay engaged

Mon, 05 Jul 2021 20:40:50 -0700

My time cutter zero turn will run fine. However, the blades will not stay engaged. I will be mowing and the blades will just shut off. I push the switch button down and pull it back up and they engage again. The engine does not stall or react.

I am assuming the switch is bad, but before I start chucking money, I figured I’d ask.

Some days are worse than others. Some days, I can mow for hours without any issues. Today, I could mow for about 5 minutes at a time.

Troy-bilt lawn mower: Pulley mechanism on shaft upside down

Sat, 19 May 2018 08:08:55 -0700

Hello. I just bought a used Troy Bilt Self-propelled push mower. It has a Briggs and Stratton 650 series (model # 7bsxs-1901vh) engine. A Belt is supposed to run from a pulley attached to the shaft where the blade is, to another pulley near the front wheel drive mechanism in order to propel. I went out and bought the proper belt, but the problem is that it looks like the pulley mechanism attached to the shaft was placed in there upside down. I say so because the belt doesn't line up properly when I attached it and it is definitely because of the pulley on the shaft being a bit lower than level. I took the bolt off in order to detach the plade and get to the pulley mechanism, but I don't see any way to remove the pulley mechanism in order to put it in right side up. It should be noted that the part also said "NH-Made in China" and read upside down. This is a very trick area to work right near the crankshaft and it looks like brute force may have been used to attach such a piece here. Any help is much appreciated! Thank you!

Ego Walk Behind Mowers LM2100SP Version 3 2018: Need electrical schematic / wiring diagram or the LM2100SP

Sun, 29 Jun 2025 10:35:10 -0700

The self propelled feature of this mower doesn’t work. The blade motor does run. I checked the wiring for pinches and breaks at the pivot. The MOSFETs both test within range with a diode tester. When I pull the self propelled lever, the LEDs on the battery light up, telling me the circuit is intact. I applied 12 volts to the self propelled motor and it works. As a retired ASE CMAT L1, I rarely used the parts cannon to diagnose. The PCBA and the wiring appear to be common fail points, but both test good on this mower. Any assistance is greatly appreciated.

Toro Walk-Behind Lawn Mower: Why does the pto switch blow

Sat, 30 May 2020 02:58:30 -0700

PTO switch blows. Warner electric mag stop # 5218-76 tests OK with 2.2 resistance and the AMP draw is 5.53 at beginning of test then drops down to 5.40 +- 8 . I can jump the plug at the switch ( switch removed) and the PTO clutch works and jumper wire does not get hot. I do not see any damage inside the clutch and bearings are very good.

TORO 62" Z MASTER Z256 Model 74225 - 210001451

I can not find anything wrong with wiring, and all safety switches are in working order.

Very well kept machine I bought new 1082 hrs KOHLER 23 hp gas
