I have a model yth2348 mower. How do you adjust the speed of the mower. I have changed the drive belt but it still runs slow.

You got it! Replace the drivebelt!

how do I stop the noise when i let off the pedal you have to push in to start the mower it makes a bad noise . but when I push it in it stops. how do I remove the lower deck to get a look at drive belt.

Some self-propelled mowers include a speed control, but sometimes it may seem that no matter how you adjust it, the mower just creeps along at a snail's pace. Most likely this isn't a mechanical malfunction, but an adjustment is probably needed.

Very tall or thick grass can bog down a self-propelled mower, but adjusting the height of the blade may allow it to roll through and cut the grass at normal speeds. If the blade is low, the amount of cutting required may slow down the movement of the entire mower. The frame of the mower may also stick in the high grass. Raise the blade little by little until the mower rolls at the appropriate speed. Going up hills may cause a similar response.

It's possible the drive belt on the mower can slip. Inspect this part to see if it is loose or cracked, and replace the belt to restore power.

Looking at the IPL(exploded parts list) will give you a good look at the route of the belt. Here is a link to use and find your model

I think the only logical conclusion is that your hydrostatic transmission is shot. If you know the model number, I think they
are stamped on the bottom, you can look over on ebay. There are some NOS vendors over there and they may have one. There are also mower junkyards around, believe it or not, and if you can find one you may find a serviceable replacement.

You can replace the drive belt, and make sure the springs on the tensioner and clutch pulleys are good, but the belt itself has no adjustment. They stretch a bit with age, also not uncommon for the transmissions to go bad which means slow or no movement even though the engine runs normally.

Hello,

do you need to know the belt configuration for this mower ive attached a user manual that shows the configuration and all adjustments on the deck and belt...

Hope this helps

You need to adjust the gas pedal. Info should be in the owners manual. I have it in my Troy Bilt Bronco manual. It say to adjust it in my book after replacing the trans drive belt. Maybe that will help.

Is there the proper amount of tension on the belt?Look in your owner's manual to find out how to adjust the tension.

put oil or grease all the shafts and bearings inside and out, if possible adjust the cutter blade contacts.
