SOURCE: Which way do the mower blades mount, on a Craftsman DT4000, 19HP Mower 42" deck?
Hi, make sure to put your blade curve end up. another word facing the motor
SOURCE: i need belt diagram for 42 in deck
You can go to the Sears website an download a free owners manual that shows what you need.
SOURCE: Removing pulleys from 42 inch Craftsman mower deck
Put the blade back on the star on the shaft and tighten it down. Now you have some backup for the pulley nut. You may have to wedge a 2x4 between the blade and deck. THe EASIEST way is get an impact and zip it off. :-)
SOURCE: Mower Belt Won't Engage
The fact is that belts don't stretch. They wear down on the sides, causing them to ride deeper in the pulleys and they APPEAR to be longer. Check belt "width" to see if it is less than one half inch. Most craftsman riders use half-inch (AKA: "A section") belts.
Testimonial: "I removed the mower & checked everything - pulleys, bearings, mandrells, springs. All OK. Re-assembled and it works again. Thanks for your feedback."
SOURCE: drive belt is too loose, already replaced belt and
I had the same problem with my Craftsman Lawn Tractor. The Drive Belt (which is not adjustable) is only engaged when the Brake Pedal is released (the Brake Pedal is located on the left side of the tractor, near the foot rest on my Tractor).
The Symptoms: My Tractor lacked driving power, and would not go up an incline, but the mower deck was powerful and working fine, even though the Tractor seemed to lack power and moved slower than usual, and would not travel up an incline.
I too, changed the Drive Belt, which initially seemed to help somewhat for a very short period of time, and then the same, lack of power problem, re-appeared again. The belt was not the problem, but only seemed to work somewhat due to the rougher texture of the belt's surface against the pulleys.
I also changed the Plastic Clutch Pulleys that engage the Drive Belt, thinking that they may have been worn down to a point that the Drive Belt could not fully engage with these Pulleys. No Luck.
NO ONE, NOT EVEN SEARS ON-LINE REPAIR ADVICE CENTER HAD A SOLUTION. THIS WAS VERY FRUSTRATING INDEED.
There had to be a solution: After much investigation, I eventually discovered the problem, which actually was easy to solve, and I would like to share this simple solution with others facing this same Frustrating Problem.
The Brake Pedal, when released, causes the Drive Belt Clutch Pulleys to move, and thus Tighten the Drive Belt. When you look under the Tractor, there is a Protective Metal Plate mounted to the Bottom of the Main Tractor Frame which covers the Brake Pedal Shaft and attached Mechanisms. Over time, Grass Builds up in between the Protective Metal Plate and the Tractor's Main Frame Deck, creating a very narrow space between these two pieces of metal.
This area is very difficult to get at, and almost impossible to clean out. Over time, Grass Clippings accumulate in this hidden area, and harden to an almost rock hard clump.
These Hardened Clippings accumulated between the Brake Pedal Mechanism and its fully released metal stop position. Thus, preventing the Brake Pedal Mechanism from moving to its fully engaged position.
I used a long screw driver to break up the compacted grass clippings, and an Air Compressor Blow Gun to break up the packed grass and blow the area clear. It takes awhile to do this cleanup, and is a bit messy, so do it outside, but be patient, and be sure to clean out all the grass that is lodged in this hidden area.
What was happening was that the Packed Grass was so dense that the Brake Pedal could not Fully Release, thus only Partially Engaging the Clutch Pulleys and the Drive Belt, hence the appearance of a loose Drive Belt even when the Brake Pedal was released.
Once the Packed Grass Debris was cleaned out, you will immediately notice the Drive Belt being tighter than it was previously when the Brake Pedal is released, and when you test drive the Tractor you'll find that everything works perfectly, like it was brand new.
Good Luck...
