Not enough torque. Only use 1/2 width of deck on tall grass, go real slow, Ensure side discharge is open! Ensure blade is sharp. Replace spark plug once a year and clean replace air filter. check oil level 30woil.

Your blades may be erroded on the edges? Or the center blade hub might be damaged or worn.

good time to inspect all the blades and spindles for wear or damage.

Sharpen the blades,very sharp,and lift the deck one notch from where you normally cut.Some times the blades will get dinged,or the ends of the blades will dull.

SOURCE: I recently changed the oil and sharpened the blade

Hi skin2ed...

You could have gotten some dirt/debris into the carburetor when you changed the oil because of the angle you tilted the mower.
I will recommend that you do the following:

Check/Clean/Replace your fuel filter if you have one.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a year old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.
Once you have your carburetor rebuilt that should solve your problem.

Can i stretch the spring to adjust the governor

No that will not adjust your speed the governor is there to protect from overspeed and give more power when required like heavy grass cutting,it is operated by air generated by the cooling fins or internally...so don't mess with the spring.. Good luck

Polan selfpropeled mower the blade is not spinning fast enough and hardly cuts the grass

Blade speed equals engine speed. Check your carburetor and fuel pipe
Make sure you sharpen the blade with - this is more important for a good cut.

There is not a governor on newer mowers. Ease mower thru grass slowly, if starts to slow down stop, let mower speed up. In tall grass only use 1/2 of the deck width with side discharge open. Ensure spark plug is clean and gapped properly, replace once a year. Ensure air filter is clean, replace once a year. Ensure oil is full. 30w oil. Always use Stabile in gas. Use carb cleaner and clean outside of carb to ensure choke lever is free to rotate.

I have a self propelled Toro walk behind that does not have a throttle control. Stalls out if grass is just a bit high. How/ where do I adjust throttle

Most new mowers do not have a throttle adjustment, the motor has a govnor that helps the motor speed up when the load requires it. The first thing you should check is that the blade is sharp which makes it easier to cut the grass. If the grass is still too high for the motor to keep up, it's usually easier to raise the deck (lower the wheels) so you are not cutting as much grass on each pass. Then lower the deck to where you want the grass height to be and make a second pass.

Toro 22inch recycler mower Cut the lawn fine last week (wet grass) This week very hard to pull the pull cord Too tight to pull fast enough to start engine Any ides?

hi there

have you checked and removed any built up grass/ mudd from the blade/ bell housing ?
does the blade turn freely after this ?

remove the pull start cover assy does the engine rotate freely ?

make sure the blade brake is not stuck on ( if these units use them )

if no check your oil level ?

if you have no oil reading on the dip stick you could quite possibly have siezed or partially siezed your engine

make sure you have not hydraulicd oil into the combustion chamber ( this raises compression )
to the point where it has too much compression and oil will not compress and causes a loc near tdc

take look and let me know

Blade slows down when grass gets thick

Hello,

The reason the blade slows down when the grass gets thick is simply because the mechanism operating the blade is weak and cannot move fast when on thick grass.

I suggest you troubleshoot the mower. After that, the blade should work fine when the grass gets thick.

Also, some mowers normally gets slow when grass gets thick, so after troubleshooting, if the mower does the same, then you already know it has to be slow when trying to cut thick grasses.

Take care

To mulch my grass clippings, do I have to use the side discharge or can I simply remove the bag and insert the rear plug?

Insert the rear plug if mulching is desired. The key to mulching is to mow the lawn frequently.You want to keep the mower deck height high enough to cut the grass and allow the mulching blades to work, but just low enough to actually cut the grass in a smooth uniform height. To low of a cut setting will clog the mower and create a mess. 2 times a week is a good frequency to start with.
