Cub Cadet riding mowers make the tough, sweaty job of mowing your lawn underneath the hot summer sun go by a little faster. The LTX 1040 is a smaller riding mower that features 19HP single-cylinder Kohler engine and two blades on a 42" mower deck. You should have a regular blade sharpening schedule, but in the case that one of your Cub Cadet blades becomes bent or damaged, you'll need to replace the entire blade. To replace your Cub Cadet LTX1040 mower blades, follow this Cub Cadet Replacement Guide.
1) Make sure the mower is turned completely off. Set the parking brake.
2) Lower the mower deck to the lowest setting. You can do this by moving the adjustment lever on the right fender to the lowest notch.
3) Underneath the mower, find the mower clutch pulley. Remove the nuts from the belt guard – you'll need a socket and ratchet wrench for this step. After you've removed the nuts, you can remove the guard. Take the mower drive belt off from the clutch pulley.
4) On the mower deck's left side, find the deck retaining pin. Release the deck from the mounting bracket by removing this pin. Repeat this step for the deck's right side.
5) After removing both retaining pins, raise the deck adjustment lever to the highest position.
6) Locate the retaining pin on the deck engagement cable near the mower deck's rear. Remove it. Then, remove the retaining pin from the stabilizer rod at the front of the deck. Remove the rod from its mounting hole.
7) Now you can slide the mower deck from underneath the mower. Make sure that the underside is facing upwards. Use a wooden block to keep the blades from turning. Place this wood black on the center baffle on the deck.
8) Make sure you are using work gloves for the remaining steps! Remove the center nut from the blade you need to replace.
9) After the center nut is removed, you can remove the blade by lifting it straight off of the cutting deck. When you install the new blade, its serial number should be facing upwards onto the cutting deck. Using a torque wrench, tighten the nut between 70 and 90 foot-pounds.
10) Turn the mower deck back to its original position and slide it underneath the mower. Re-install the deck by following the removal steps in reverse order.
