Grasscutter: find the fault!

Something is wrong with this picture. Can you figure it out?


Here are several earlier Find the fault puzzle cards you can try.

Will unmask submitted answers in a day or two, thanks.

    Many faulty things:

    wheels too smooth…it should be made of rubber and rough.

    large driving pulley does not have teeth to move the chain..this one is for rubber belts..

    wheels should be in the back…this grasscutter is only good for going backwords..

    driving chain is too low and rubbing against the ground..

    driving chain should be covered for safety..

    there is only one sprocket for the chain to hold on to. How is it going to drive the second wheel with a smooth wheel face?

    The large gear has no teeth.

    1. The large driver sprocket is a flat wheel, the chain would slip. It must be toothed like the smaller, driven sprocket.

    2. The driver sprocket is too large, it touches the ground. It must be smaller in diameter (or else the roller diameter must be larger) to avoid contact with the ground which will damage the chain and/or cause it to derail.

    3. The blades appear to be squared off on the top, not sharpened.

    Well it looks to me that the large drive pulley that would run the chain around has no cogs.

    i think the smaller roller at the front will push the grass down and hence make it harder for the blades to cut the flattened grass

    Why smooth out the grass before you cut it?

    The front roller-bar is on backwards.

    The blades should be going clockwise (against the blade)

    If you were to run the machine with the gears here, the blades would rotate the wrong way (anti-clockwise).

    no teeth on the rear wheel. the rolling motion of the back roller won’t drive the chain because the back “gear” isn’t a gear, it’s just a wheel.

    I think the bigger wheel is missing the tooth to hold the chain….

    Rear pulley should be a sprocket instead.

  13. Obiwan | Profile

    The pulley attached to the large, rear wheel lacks teeth. the metal chain will slip on the pulley and front shears will not be turned to cut grass.

    There are no teeth on the back gear.

    i think it’s the chain on the outside!!! it doesn’t look quite right!!!

  16. money226156 | Profile

    either the chain or the cylinder…

  17. joe | Profile

    You wouldnt have that roll bar at the front to flatten the grass before cutting it!

  18. deejam | Profile

    Is that chain guard?

  19. RK | Founder | Profile

    the main one we were looking for- the chain would slip since no gears on rear wheel
