Default Parts Needed to Make a Quietline CC Quiet

I've read a couple of older threads on here where people are looking to make their Cub Cadet Quietline tractor....quieter, or just plain quiet. I've noticed that my 1450 sounds like a rattle trap too, so I've disassembled it and plan on doing the common fixes - motor mounts, driveline check, tighten all bolts, tune and freshen engine, replace cracked muffler box, and obtain and correctly mount side panels and hood.

My question here is what improvements can I make when reassembling the tractor to quieten it even more. My thoughts are adding rubber washers to hardware at the muffler box. What do yall think of that.......if that is a good idea, do you have any other suggestions? Making a McMaster-Carr order soon!

The only way to make a 14HP Kohler single cylinder Cub Cadet quiet is:

A) tear out the single cylinder engine,,,

B) install a twin cylinder engine,,,

That piston in the single cylinder engine is too big to silence,,,

I understand that! Yeah, Im just looking for suggestions to cut the rattling problems out. Funny thing is that for years, I thought the quietlines were "quiet" not only by the side panels and muffler out front, but because they outfitted them with twin cylinder engines. Not sure where I got that from. haha.

I found that a rubber molding applied to the edge of the hood, all around where it contacts the dash, helps a lot. Like this stuff.

Lots of other stuff rattles. The wire mesh in the front grill casting can be loose. The muffler shroud is a common rattle point. The mule drive, mower deck support frame both can rattle/vibrate.

You just have to find each item and subdue it!

What he said! Once you cross to the "twin side" you'll never go back. Well, maybe for a little nostalgia.

Depends on your preference. I've run Dad's 125 and 782 and I much prefer the 125. Not knocking (no pun intended) the twin cylinders but I'd rather have a K series Kohler.

You are now invited to come to NC next spring and run my fleet of twins (1811, 982, 2072,2284). If you still want a single after that, so be it--but at least all the grass here will be cut!

I really think that the key to reducing vibration is to get the engine timing as accurate as possible. And when you replace the rubber mounts, there is a break in and adjustment period when you tighten and loosen the bolts till you get it just right.

Vinyl door edge for back edge of Quietline hood McMaster Carr # 8451A47

Hood hinge tighten up;

Sometimes the spring that holds the side panels together will rattle against the muffler box, some put a length of rubber fuel line over it.

I have heard of people using wood stove gasket rope between the muffler box parts, never tried it.

How about your driveline? If the ball bushings, driveshaft ends and rag joints are worn out that will vibrate too.

The trim edge strips require modification to the hood if they're too thick, mine is from kurk and pushes the edge of the dash in and prevents the hood from closing entirely.

The only experience I've had with a twin was a gutless cyclops at an auction and a junk briggs. The best one I've found are the magnums but I've never owned one.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
