Blade alignment
Hello. I just recently joined the forum and need some help. I have an LTX1040 rider. I hit some rocks last year which ruined my blades and also threw off the timing (alignment) of the blades. I have the new blades on the deck and according to the manual, when the pulleys are lined up correctly, the blades do not. I lined up the blades correctly by reseting the drive belt and it works fine until I go to disengage the blades, then they hit each other when they slow to a stop. When I look under the deck, the blades are out of time and not 90 degrees apart. There is a triangle on each pulley for the alignment. Here are two photos, #2 & #3, of how the blades look when the pulleys are aligned correctly and two photos, #1 & #4 of how the pulleys look when the blades are lined up correctly. In the #3 photo of the top of the deck, the triangle on the left is at 3 o'clock and the right is at 6 o'clock, this is how the book shows the pulleys should be.
Can anybody help me trouble shoot this.  The repair shop is 3 weeks behind and they want $75. just to look at it.  Thanks IMG_0177.jpg IMG_0176.jpg IMG_0175.jpg IMG_0178.jpg

Welcome to OCC!
My first thought is that one spindle may be bent from hitting the rocks, slowing down faster than the other, and throwing off the time. Check for a bent/bad spindle by removing the belts and flipping the deck blades-side up, you might need to block it up so the pulleys are clear to spin. Give each blade a spin, see if one wobbles or is harder to turn. Bill

I think i would pull one or both pullys off and check it out. Not real sure on that model but there may be keyways on the pyllys/shaft you may have sheared one.

How's the timing belt looking? Shear off or wore down any teeth? Is the timing belt tight? I think before you did any mechanical damage that belt would be the weak link and take the hit. But then again, never seen a timed deck so just guessing.

like others have said it probably sheared off a key.

You may have sprung the deck!
I had a ford LT years ago that my brother had struck a curb box with. It was never the same after and would never leave a decent cut. Clean it well and look for cracked paint in the area surrounding where the spindle assly is bolted to the deck.

Maybe Im missing something but why cant you line the blades up where they need to be and roll with it? I don't understand the need to have marks on the pullies lined up as well.

Cub has had plenty of trouble with the timed decks. Just my 2 cents but I'd check for broken keys or other stripped splined connections, if you don't find a problem I'd put it back together with the blades 90 degrees to each other and see what happens.

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.
