Ouch! Is the clanking sound coming from the blade / deck or is it in the engine. It sounds like you hit a stump or a rock in that tall grass and stopped the blade. Under normal operation, what is suppose to happen is that the timing key will break off and you can replace it. If not, then usually the crank shaft will get bent and in such case, you probably need to replace the engine. It is also possible that on the lighter side, something got knocked out of kilter and the blade is hitting the deck on one side. Look underneath and turn the blade AFTER YOU REMOVE THE SPARK PLUG WIRE!!! NEVER EVER TURN THE BLADE WITH THE PLUG WIRE ATTACHED; THE ENGINE COULD START AND CUT OFF YOUR HAND!!! See if the blade is hitting anything in its full revolution. If it is, it'll make a hell of a racket. Good Luck.

First off I would not be cutting grass when it is wet. I know our time is scarce, but in the end you wish you had left the lawn for another day.
My thoughts are that the mower deck, the part facing the ground is full of accumulated grass and mud from neglecting to cleaning the under deck. Turn the mower on it's side (don't forget to remove the spark plug and maybe place some plastic to seal the gas tank fill spout) and you may notice an abundance of accumulation. Find a flexible scrapper and just start removing all that debris. Clean it well and for additional remedy, power wash the area that you have just scraped. Check your blade perhaps it needs scarping or replacement? When removing the blade watch your hands by placing a 2x4 in a location that does not allow the blade to move. Even through the blade is dull, it can still give you a very nice gash, which will have you belting the mower with a sledge hammer. I have also learned through the years is to not use any grades of gas other then high-test or premium. Stay away from the ethanol fuel as it is nothing but trouble for small engines. Most of what I have said is likely nothing new, but I do hope that you get some help from my answer. Check the spindle too to make sure it is not out of alignment.

Why does my new holland tc 30 stall after 20 minutes of mowing?

Is it a mulching mower that doesn't have a bag?

If it has a bag, you may need to empty it more often in the spring because the grass is wet. If it isn't emptied fast enough, it will clog and the blade will stop, causing the engine to stall.

Why does it bog down in grass maybe 6 " high?

The likely cause of this is that the grass is too high for your mowers deck. You should try just mowing about 1/3 of the blade at a time (if you can) until you reach your desired length, so if you grass is 6" high, only take off about 2" at first to reduce the stress on your mower. Set your mower deck to it's highest setting and give it a shot.

Also, be sure that the blades are sharp, and if you don't have mulching blades, you should get some! Grass this high will leave long clippings on the lawn which can suffocate the grass, mulching blades will chop up the clippings into smaller pieces, which is beneficial for your lawn!

Finally, make sure you aren't mowing wet grass. If you mow when the grass is wet the clippings can stick together and clump up under the mowing deck which will cause excess strain to the mower and maybe even cause it to shut off.

If none of this works, you may want to use a string trimmer to remove the first two inches of your grass and then continue mowing as normal!

Hope this helps! Happy Mowing!

Following fuel leaking through the air filter and exhaust and checking the float bowel & putting the carb back I cannot engage the cord. The break is deploying and was working prior to the fuelleakage

remove spark plug and try it if gas blows out you have a carb problem rather sounds like the fuel has leaked and filled the cylinder . means float is sticking in the carb .

During mowing grass will gather underside of deck leaving 2 streaks on r and l if you turn deck off grass will fall out of deck before restarting u need tgo move or mower will stall from grass build up...

There are a couple of things going on here. First, the blades are likely worn out and need replaced. As they wear and loose some length they can leave a trail. Second, if you have regular blades on a deck configured (by having discharge plugged) for mulching and you are using regular blades, then you can have a problem with build up. Third, you can have clumping problems if the grass is not dry when you are mowing.

I hope this is helpful for you.

Why does grass get hung up in the chute for a rear debagger?

Typically, wet grass or tall grass will get caught. Mow only when dry and make sure your blades are sharp. Mow with the engine at full speed [VERY IMPORTANT] adjust your ground speed by using the proper gear for your conditions. With the engine at full throttle, choose a lower gear when cutting higher grass. Make sure the air outlet of the rear bagger is unobstructed. It has to be able to breathe.

I trust you will find use of these techniques will lessen the clogging rate you are experiencing.

Thank you for your question @

When it starts in makes a noise like medal is rubbing until it gets to full speed then it stops and goes back to normal. This take 3-5 seconds. This is a tore 20 inch ecycler, i have had it about a year.

The first thing I would do is to look under the deck and see if the blade is hitting up against what I call a ring wall. This ring wall is in almost all mowers wether electric or gas. I believe it,s designed to keep the cut grass from clumping up under the deck and not discharging out the shoot. Sometimes grass, twigs, rocks, etc. get caught behind this wall PUSHING the wall out towards the blade. The blade in turn starts hitting the wall making the sound you are hearing.
First removed any grass from behind the wall, second take a hammer and tap the wall back to were it should be. Rotate the blade buy hand to see if their is clearance, if so you should be ready to mow again. GOOD LUCK.

Have a 3 year old 6.75hp Craftsman SP mower. Hit a stump yesterday with the blade, which stopped the engine instantly. Started again without any problem but now no matter how clean it is underneath or how...

Some things to try:
Keep the mower on a smooth surface - concrete or asphalt - does it still clank & stall?
If it stalls on concrete, try loosening the gas cap.
Remove the plug, lift the mower and rotate the blade, is it or the motor shaft bent?

I have a single cylinder Ranch King riding lawn mower. Model # 133K6796205. Bought in 1993. I need to know what type of oil to put in it? I am also having a problem with the grass collector. Even if...

Hello You can use straight 30 w oil most engine manufactures agree for summer equipment now for winter where it gets cold like in a snow blower the request you to use 5-W30. As far as your grass collector check your blades #1 to see if they are the correct blades for that mower. #2 yes the engine will overheat as the clumped of grass will slow down the blades causing more load on the engine.This is not a uncommon problem wet or damp grass will clump up even if you do not have a grass collector,it will stick under the deck again causing problems.Hopefully this helps.
Thanks Ben
