Question about Craftsman 20 Hp 42" Deck Lawn Tractor

1 Answer

How do I tighten the deck belt on a Husqvarna YTH2348?

I have a 2010 Husqvarna YTH2348 lawn tractor. It started running rough last fall, so I took it in and they cleaned the carb, changed oil, checked belts, tune up, etc. it was running great, a loud "whoosh" sound when engaging the blade and cut really well. After a few mowings and aerating my yard, I noticed what sounded like slack in the belt. Then the deck belt popped off after disengaging the blades after mowing the front lawn. I just replaced the belt and no change. Any ideas? Thanks!

SOURCE: Craftsman 42" mower deck won't disengage

Try pulling on the cable coming down to deck. This cable might be your problem. Also check that the spring on the end of this cable is present and functional.

SOURCE: Blades won't disengage

Hi,
When the mower is off and the clutch is disengaged you should not be able to physically turn the blade(s) if you can then you need to adjust the blade brake (look on the mower deck and you should see what appears to be a brake pad). Your owners manual will show you how to adjust. If you need a copy of the owners manual then I would suggest going to www.managemyhome.com and downloading a free copy of the manual for your mower (Need model number which starts is located under the seat).
Good luck!

SOURCE: I have a Craftsman GT 5000 Garden Tractor, 25 HP,

Depending on your engine.. Briggs and Stratton or Kohler there are 2 different seat switches that are used to power the PTO clutch. The seat switch can cause the PTO clutch to disengage anytime there is not at least 70 lbs in the seat.

The PTO drive wiring has a 30 amp fuse in it. If by chance a stick went through the belt and tore off the wires at the PTO clutch (Common failure) even after you repair the broken wire you still need to replace the fuse.

Check the PTO clearance gap. It should be 0.012 dis-engaged. Any other value and the clutch will not work correctly. Adjust the clutch if necessary.

There is a 2 pin Pigtail just off of the PTO Clutch that you need to check for voltage at the connector. Probe the back of the wires if you can and your looking for 12V DC under the following conditions.

BRAKE ON or tied down
KEY ON
SEAT (Briggs and Stratton engine only) Someone needs to be sitting on the seat.

Then Pull the PTO Switch out. You should hear the PTO Clutch CLICK. If you hear the click there is no need to check voltage. The PTO switch is a multi function switch and it is quite possible the PTO switch failed. I doubt that the PTO Clutch has failed as they normally give you some kind of noisy indication that they are failing and don't fail straight away.

So.. In short
Check PTO Switch (Red wires) to usually red or brown thru the switch
Check 30 amp fuse
Check PTO clutch wires near PTO clutch (They get torn from something traveling through the pulley)
Check PTO clutch clearance at 0.012
Check Brake switch for an audible click as you depress it some distance No click.. possible bad switch
Listen for Seat switch Click as you slowly add weight to the seat. No Click or any click and it can still be suspect due to the Briggs and Stratton installed engine ones have more than one function.. Ignition and PTO clutch power.

The actual wiring diagram is on page 35 of the owners manal that can be found here:
http://www.managemylife.com/mmh/owner_manuals/27245/CRAFTSMAN-Lawn,-Tractor-L9910386?brand_name_search=917273023

Lastly... check each of the mower deck blade bearings. A seized bearing can cause PTO problems.

Hopefully you have enough information to solve the mystery. If not just respond here and I will help you.

Thanks for choosing FixYa.

Transmission belt slips, can it be adjusted to tighten


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.

Husqvarna gth main belt keeps breaking


Make sure the mower rake angle is not too much,On level floor point one of the blades in a front rear orientation,measure height of blade from floor the front measurement should be no more than 1/4" lower than the rear measurement.If the front of the mower is too low the angle the belt has to run is too much and the belt will twist and wear rap[idly.To raise the front of the deck there are either one or two adjustment rods that attach the front of mower deck to frame tighten this adjustment up to raise the front of mower deck.
