When mowing it will idle up and down because of the amount and thickness of grass you are cutting. This is because the blades will struggle cutting thick grass so the engine needs more revs to keep the blades running at a constant speed and that is also why your mower may slow down because it has used the majority of revs to cut the grass and their are not many revs left to keep the wheels spinning
The up and down revving could also be caused by a dirty/clogged air filter.
blade needs sharpening,or belt is slipping for mower deck.
Riding mowers can make an otherwise tedious job easy and even fun. However, before investing in a riding mower make sure that your lawn is large enough for it. A push mower makes sense up to a certain area. Then, sit down on the lawn mowers and stay there for a while. Do you notice any discomfort in parts of your body? If so, note it and then sit down on the next one. Are there any differences? Is it more comfortable? After a while, you should have found the best riding mower and, hopefully, the price is right too.
You can help protect your nature bye giving it love (watering it , giving it water and sunlight) You can also protect nature bye not mowering it down or standing on it
Hi, The float valve is leaking through. The fuel can leak in the intake and down into the crankcase, where it dilutes the engine oil.
Assuming the blades are rotating but not cutting grass, the blades may be very dull or they were replaced upside down when removed for sharpening.
Let the gas out of the carb. Either loosen it a little from the base and let it out, or just letting it sit and cool down should do it
Disengage blades, push down and/or lock it and turn the key. If nothing happens, the most common parts for failure are the key switch and the solenoid.
Most common cause of lopeing (revving up and down) is a dirty air filter.
A 17.5 horsepower Murray riding lawnmower should always have 1.5 quarts of oil in it. You may have to add more than that after an oil change because some of the oil will go down into the oil filter.
yes run wire from ignition coil to bottom of seat use spings or whatever you not to make the wire ground to the seat pan when rider exits the mower this will automatically shut the engine down when rider falls off to save yourself some time and cash just go and find a 2 wire seat switch off of an old riding mower and run one end of wire to coil and the other to common ground
!st let the blade cover down by loosing the chains on both side of the mower. this will give you hand space. Of course take off the plastic cover and unconnect the sparkplug 1st. I dont know about anyone else but i will loosen the four bolts holding the engine down to give you the wiggle room you need.
Well your transmission has to be overhauled. The shifter fork moves up and down on the shift gear and in and out of the gear cogs to allow it to shift gears.
