SOURCE: Why isn't the center blade on a john deere LX178
Of course with everything off, reach under the deck and turn the center blade by hand. If:
1. the blade turns by itself and nothing else moves, you need to tighten the retaining bolt more.
2. the blade, retaining bolt and drive shaft turn, check to see if the pulley above it is turning.
a. If the pulley turns freely check that the drive belt is going around it to power the blade.
b. If the blade turns with the drive shaft and the pulley doesn't, check that the pulley is still properly connected to the blade shaft. Some have a key in them that can split, others just have a bolt on top holding them tightly on the shaft.
SOURCE: john deere lx178 will run in reverse when i try to go forward bogs down to a crawl
i have found over time the linkage wears and the rod needs to be adjusted to make up for the wear
SOURCE: The deck mower on my John Deere LX178 is all the way down and will not raise. Any suggestions?
push down on the button to raise it
1) NEVER adjust to where the deck wheels touch the ground. The wheels are to ride 1/4" off the ground. 2) The long lever to your left which raises & lowers the deck has 3 settings. 1- Fully back toward you which has the deck raised (called transport mode). 2- Halfway down which is the normal mowing mode (called float mode) 3- Fully away from you which sets the deck fully on the ground. This mode is ONLY used for VERY rough terrain where the deck risks getting pushed into "transport" or "full up" mode & getting stuck there. 3) On front-to-back tilt, the front should be 1/2inch lower than the back for least damage to the grass. Ok-now to adjust "cutting" height. 1) Park on a level, flat surface. 2) Pull the deck lever fully back toward you to put the deck into "transport" mode. 3) twist the "cutting" height knob (just below your seat) to the height you want the grass cut. Has choices by 1/2" increments from 1" to 3.5". The deck in "transport" mode is 4". 4) Lower the deck lever to the midway/"floating" mode point. 5) Adjust each deck wheel with its own peg & pin to have at least 1/4" clearance from ground. Thats it for "cutting height" adjustments
