Can I use extra thick rubber washers instead of original mounts? Engine seems to have excessive vibration.

At idle or throughout the rpm range?

Mounts are available thru McMaster Carr.

Yes you can. I have made several garden tractor so far.

you need 2-1/2" x 3/16" or 1/4" bar stock.

Cut bar stock to 2-1/2" long pieces.

Align the old motor mount to the bar stock, and mark the 3 holes.

Make sure that the 2 holes for the motor mounts fit the frame.

I think a 1/4" is right for that.

Then drill a 3/8" hole for the center hole for a 3/8" bolt.

 

I got 1/4" thick rubber belting that was 6" wide from a machine supply store.

I used a 1-1/4" hole saw to cut the rubber.

Drill the center hole out to 3/8" for the bolt.

You need 2 per mount.

bolt or pop rivet the bar stock to frame.

You also need a fender washer with a 3/8" hole.  (which you can drill out to 3/8" dia.)

Note - do not use a standard 3/8" washer.  It will not support properly the rubber the as a fender washer will.

 

With the motor in the garden tractor.

Put the fender washer on the bolt then the rubber and from the under side of the bar stock, push to bolt through the hole in the bar stock and put the second rubber on and through the motor mount frame.

You can put the second rubber between the bar stock and the motor mount frame before you put the bolt through.

 

Put a nut on the bolt.  Then tighten by hand.  Put a second nut on as a jam nut.

The trick it is have the bolt be able just to turn a little.  You have to try it and test it, so that the bolt can turn.

Make sure when tightening the jam nut that the first nut does not turn.

Do the other 3 mounts and check them all that each bolt can just turn a little.

 

The reason why the bolt has to turn a little is that the motor can move freely.

If mounted like a stated you will not know the different in the motor mounts.

 

good luck and have fun.

Many times those mounts are worn out and not functioning properly even though they don't look bad from the top side. The other issue is idle speed. The idle speeds for rubber mounted JD Gt's are much higher than you would think. The range for  214 is 1700-1900 rpms. The reason for this is that the idolaters are tuned to deal with frequencies above a certain speed. They can actually amplify vibrations if they are worn out or if the idle speed is set too low. You need to inspect each isolator and verify that they are ok. They are still available from JD but are pricey. You can probably get a good replacement from driveline suppliers or from McMaster Carr for less$

Ok thanks good info. I may increase the idle speed and see if this helps. I'm sure mounts need replaced also though.

Sounds like balance gears were removed from engine.
