Question about Electric Lawn Mower

1 Answer

My electric lawnmower sometimes does not start, just humms. Then I TURN IT OVER, AND TURN THE BLADE A LITTLE BIT. the blade feels hard at first but soon feels loose. then it wil start as normal

Every time I have to turn the blade a little by hand before it will start. There is no smoke or smell or anything and the motor runs and cuts perfectly. The mower is about three months old.

The lawnmowers electric motor has a bad spot on the armature. You need to replace the electrical brushes that contact the motor. If you are lucky you may just need to clean them and reinsert them in to brush holders.

SOURCE: BLack and decker electric lawn mower blaDE IS loose and not turn

If it's like mine (MM 875), it has a plastic "clutch" that has little edges on it that broke off when I was chopping sticks with the mower ;-) Went to the local B&D place and got a new one for less than $3.

But now I'm worrying about the nut holding the blade on -- if I try to get it good and tight, the plastic "clutch" spins around off-kilter... Funny how I never even looked at the blade after I bought the mower used, but never worried about the blade being loose and flying off.

Hello

The generator makes the particular rotary cutting blades spin so that you can cut turf. Sometimes the particular cut grass penetrates the generator shaft and will either temperature it up to standstill or perhaps clog the particular motor. The motor needs to be checked for almost any foreign things, the armature needs to be rotated to find out if that moves openly.

A smoking rectifier is not good, it will need to be replaced.

The rectifier is required to switch AC (wall power) to unregulated DC.The brushes are the power input to the motor, with the slowing,the brushes are shorted to provide a dynamic break which quickly stops the blades. You will need to test the motor to see if that caused the rectifier to go.

I am not sure what the specs would be for resistance but it should be in the 10 ohm range for a 12 amp motor (120 volts/12 amps=10 ohms)

How to fix a wobbly ceilng fan


wobbly cieling fan
1. make sure all mounting screws between the fan and the ceiling are tight. There is probably an electrical box mounted in the cieling that the fan is screwed into. I would turn the fan light on and then keep flipping breakers off, on at a time ,to see which breaker turns off the fan light. leave the fan light breaker off and you can unmount the fan from the cieling electrical box. The electrical box may have several holes in it for mounting screws and prehaps there are some holes left empty in the box that you can put more wood screws into to help keep the electrical box more firmly mounted and that may help lessen the wobble.
Its ok to bend the electrical wiring aside to put more screws in. Just be reasonably gentle with the wiring and then bend it back somewhat to where it was before you started. make sure that wiring does not get pinched between the fan and the electrical box and that all wiring resides inside the box.
#2 This is harder to do. you need to balance the blades for the fan ,similar to how a lawnmower blade is balanced after sharpening and before remounting the lawnmower blade on the mower. also kinda like balancing a car tire. I have a lawnmower blade balancing fixture that i bought at the lawnmower shop, but i dont know if there is a fan blade balancing fixture that you could buy from somewheres. Maybe try google.com,bing.com or ask.com and type into the search box fan blade balancer
or fan blade balancing fixture or fan blade balancing jig.
PLEASE read the directions or SPECIFICATIONS before you buy the fan blade balancer, only to find out that it only fits 9 inch diameter fan blades, and your blade is 2 4or 36 inches long.
The balancer may have to fit a certain diameter hole at the center
of the fan blade. When you finally find out which side of the fan blade is heavy, you have to grind , with an electric grinding wheel, some material off the heavy side of the blade so that it is the same wieght as the light side of the blade.
Try to imagine a cone shaped center[like step drills] like the capital letter V ,only up side down, so that the point is up. ON the underside of the inverted V is a needle tiped post that upside down V can pivot in any direction on. The hole in the middle of a lawnmower blade is centered somewheres on the outside of the inverted V, depending on the diameter of the hole in the lawnmower blade. The heavy side of the mower blade will go down and may touch the level asphault or the table top, depending on where you placed the balancing fixture. THen i would grind off metal until the heavy side can up to be level with the light side of the mower blade and it was considered balanced.
an appliance repair parts store may sell fan balancers, but if the would fit your cieling fan, better ask before you waiste your money on something that wont work for what you want.

Try calling up customer service of the manufacturor of your ceiling fan and ask about repair service for your brand fan.
see what repair service has to say, im sure many others have asked them about wobbling fans.
so they should have all the answers down pat.
Two more thoughts.
1.
.MAKE SURE ALL SCREWS THAT HOLD FAN BLADES ON TO THE HUB ARE THERE AND are TIGHT. one loose fan blade mounting screw or one missing fan blade screw will unbalance the whole thing and cause wobble.
2. the fan motor shaft bearing could be worn out or round or even egg shaped. If this is the cause, the motor must be diaassembled and new fan shaft bearings installed or the fan motor must be replaced.

good luck and have fun!

Does the mower sound like it is running at full speed? Have you double checked that the blade was not installed upside down?

The pull start cord will only move about 3-4 inches and then it stops and then cord stops, Troy built- Briggs/Statton 21 inch self-propel lawnmower.


The mower's drive shaft may need to be lubricated. If you turn the mower over and try to move the blade by hand (with the mower off, of course) does it move, or is it hard to move? If it's hard to move or it won't move at all, lubricate the shaft by squirting some WD-40, 3-In-1, or other lubricating oil onto the drive shaft where it meets the chassis of the mower. Squirt enough oil to cover the circumference of the drive shaft, then try to spin the blade again. It should at least spin a little bit now. Squirt some more oil and spin the blade again, until the blade spins easily. Then turn the mower back over and try to pull the start cord -- it should pull normally now.

hi there nchernuka

have you checked that the engine to chassis bolts are still tight and the mounts are ok,

have you checked that you havn't bent the pto shaft ( this will be evident if you remove the blade carrier and blades, then the plug and pull the gine over - check wobble ), check that blade carrier is in good condition and the pto woodruff key is ok and the carrier centre pto bolt is tight

check that anything that is under the mower body is still tightly attached and is not getting swung into the path off the blades - ie catcher tounge - metal body brackets etc

i would also suggest you check the feather timming key in the flywheel too especially if it kicks back when you try to start it

cheers have a look

hope it helps pauly46

Toro GT5 lawnmower - the pull cord (to start the engine) only comes out about 3 inches - I'm afraid to pull to hard for fear of breaking the line.


First - remove spark plug and squirt 3mls of engine oil in there - replace spark plug and leave overnight.

Try pulling that start handle !
Two things may happen - it snaps or - it turns over.
If it turns over - prime fuel and start in choke setting.
If the cord snaps - undo the pull start block - and take it to a lawnmower spares depot, and buy some more cord. It's quite cheap.
Get the length right so you don't have too much.
Next - the engine is probably seized - so needs freeing up. You may be able to do this with the new cord, Otherwise - take the head off the cylinder and tap the piston down with a wooden drift while turning the crank.
Use a non-setting gasket sealant like hematite red to re-use the old gasket. Lawnmowers are quite resilient.
