Ignition coil replacement

 This post has watched 3 videos on ignition coil replacement.   This was resorted to when diagnosis reveal:   there is enough fuel, there is no problem with fuel lines, and sparks do not show at spark plugs.   So the ignition coil could be defective.   The three instances were on:    zero turn hydraulic operated lawn mower, a walk behind lawn mower and a John Deere lawn mower.  The replacement is straight forward and easy,   The parts can be purchased from Amazon (Lazada too?)

Repairing lawn mowers

 This post saw 2 videos on repair of lawn mower:   one was hydraulic,  one was simply a Kohler powered rider type lawn mower.   The hydraulic was more complicated but more robust.  The buyer handyman did to the hydraulic system:

    1.  The hydraulic assembly attached to the wheel was sent to a hydraulic shop for repairs and cost him $600.00.  For the hydraulic pumps, he did it himself.  All that he did was to replace the seals which had worn out over the years.  It looked complicated because it seemed hard to remove the shaft and there were so many parts and it took time to remove disassemble all of them.   As it is common with say bicycle hydraulic brake set repair, there was this snap ring remover.   It took probably weeks to have the lawn mower repaired,   However it gave the new owner months of enjoyable grass cutting.   He had a home made sun shade made for the lawn mower

   2.  The zero turn Kohler unit had these two problems;   wheels that seemed to leak air, and non firing second cylinder, and discharging battery.

      1.  For the tires, he initially tried to find the leak.  His final solution buy a new set of tubeless tires

      2.  For the battery, he bought a new one

For most Americans, it is throw away and buy a new one.   For the tires we will find a way to patch or get a set of interior tires.

For the one cyclinder that did not fire, using testers, after removing the air filter assembly, he found out that the left coil had no connection to the spark plug (there was no spark).  So he bought two new coils, installed and presto the lawn mower had 100% power again.   

So repair can give such helpful machine 3 to 5 years lease of life
