I have a Case 224 that i mow around my house with but every time i turn the mower deck on the front of the mower deck bends in and the blade hits it. I pulled the front out and welded it but it still bends in and the blades hit it. what should i do?
 
Which deck do you have?

Case made a 38 inch, 44 inch and 48 inch model. The 48 inch deck uses two different diameter blades. The two outboard blades are the same and the center blade is different. If you took the blades off for sharpening and put them on incorrectly, then that would cause the problem you are complaining about.

Bad bearings may also cause the blade to strike the deck. Flip the deck over and see if you can make the blades wiggle sideways.
 
ok i will try to wiggle the blades side ways. Thank you for replying to my question.

Some times when i turn the case off it backfires do you know what would cause this problem.

Think of it as Kohler's built in early warning system letting you know that this will be the last season for your engine.
You can do a compression test to confirm but it sounds like it is time for a rebuild.

Nonsense. There can be several reasons for the backfire
problem.

Excess carbon buildup in the combustion chamber can cause a
hot spot that will ignite the fuel mixture after the ignition coil is
shut off. A hot spot inside the muffler can also cause the
unburned mixture to fire.

Next time you use the tractor, do not shut it off immediately.
Instead, bring the engine speed down to an idle and wait for at
least a minute or two before turning the key off. This will allow
the hot spots to cool down.

I also suggest that you make sure you are running the correct
heat range of spark plug with the proper gap. Set the points to
18 thou. Be sure that your air filter is not clogged and that the
fuel mixture screw is set so that there is no black smoke in the
exhaust stream.

The valve lash should also be checked. Go to Kohler dot com
and get the Owner's Manual and Service Manual for the K-series
engines. They are free downloads. Your engine has ACR which is
Automatic Compression Release. You cannot check the
compression on engines with ACR without defeating it first
because it holds open a valve to make spinning the engine while
starting it much easier.

Focus on bringing everything into spec first before condemning
an engine that may well have many years of service left in it.
 
Your right. Its weird because i let it idle fore a while then I shut it off. it just sometimes backfires i don't shut it off right away.
Thank you for the info.
