42" craftsman 19.5hp mower deck wont run...burns up belt

I have a 917.270821 crafstman 42" cut 19.5hp mower. i have replaced the mandrel numerous times. I have replaced the blades and pulleys over the past few years. Long story short when i engage the blades on my mower the belt just burns in two. If i unhook the belt from the tractor the tractor runs fine. and as long as the blades arent engaged it runs fine. but as soon as i engage the blades the belt burns up. i can spin each pulley freely with my fingers. they are not bound up or anything. any ideas??????????????

SOURCE: loud screech noise from deck area

This can be due to a belt slipping or a bad spindle bearing.
And on the difficulty scale,10 being extremely difficult, The belt would be a 1 or 2 and the spindle about 6 or 7 (because the deck usually needs removed for this job)

Check proper belt routing. These models are a little tricky. Also check tensioner spring.

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: Craftsman 42" Tractor Blade Problem

sounds like either the spindal bearings are shot or maybe the spindal shaft is bent. check for up and down slop at the blades. then turn blades towards each other and check that the heigth lines up. also chec the idler pully to make sure it is not slapping around.

Did you obtain the correct replacement belt AND pulley. Double check your part numbers against the parts list for your machine. If you verify that they are correct, double check the belt routing, make sure it didn't get on the wrong side of a belt guide and is in the correct configuration. Look at your idler pulley and make sure the release spring is doing its job pulling it back from the applied position. Make sure that the arm for the pulley moves freely where it is bolted to the deck, it could be bound up with rust or debris. You should have a lot of slack in the belt when it is in the released position. If it does not then either it is the wrong part or improper installation

Mower wont engage bland to turn


Do you mean "mower blade won't turn"? This could be a broken or slipped belt or possible a damaged mandrel on the mower deck.

Do the blades need sharpening? Check the belts for tightness and the spring that holds the tension. what stops? The blades stop, but the belt is still turning? Check to also make sure the blades turn freely with the belt disengaged. you may have a spindle problem too.

How do I change the madrel on a craftsman Lt 2000 42" 17 hp? The star bolt is worn down


remove the deck from the mower, take off the blade, take off the deck drive belt, take out the bolts which hold the mandrel to the deck. put new mandrel in, reverse the whole order. do yourself a favor and take lots of before pictures so you do not have to ask how to put the belts back on. mandrels can be obtained at small engine and mower repair shops. you may just want to replace all of them while you have it apart as they are all the same age and wear.

HOW TO ADJUST THE CUTTING BLADE TENSION OF THE MOWER BELT.


There is no adjustment on the Craftsman mower belt tension. The tension is maintained by a spring. If the belt is to loose you either have the wrong belt or something is broken like a mandrel housing that holds the fixed pulleys in place.

Craftsman 42", 18.5 lawn tractor: blades are hitting in the mower deck. Blades are new and deck is balanced. Is it wear on the Mandrel - Shaft? Mandrel bearing?


Oh boy!!! Welcome to the craftsman worst design of their mower decks CHEAP!!!!! I had to replace my mandrel on the right side, side where the grass shoots out several times!! Cheap aluminum casting ****, one or more of your ears on the mandrel probably snapped, if you have an air wrench they are not too bad to replace, the screws that go into the mandrel are self threading and is easier to work on with air wrench but can be done with socket set, hope this helps!!!! good luck!

Every time I lower my mower board my mower stops or slows down. I just replaced the mandrel and also the belt. When my mower board is raised up all the way the mower works good.


Lower the deck without it running and see if anything is making contact with the mower belt that shouldn't be. Sure sounds to me like you have the belt in a bind when you lower the deck, possibly by not routing the belt in the correct position when you replaced the belt.

42 inch mower cuts uneven, what is the problem?


Several things here could be the problem. Check to see if mower deck is level, measure distance on both side on a level surface. Check tire's for low air. If you've replace the mandrel's lately, some have a left & right side & if not put back together properly this will cause uneven cutting

Cutting blade barring ***


I think that part is called a mandrel, pulley on top and blade on the bottom.
Generally you remove the deck, take off the deck belt, take off the covers, take off the blade, remove the bolts holding the mandrel to the deck. Get a new mandrel at a sears store or small engine repair shop and reassemble in reverse order. May want to do them all while you are at it and save yourself duplication of work next year.

Uneven cutting


put your mower on level ground. Concrete or pavement. Check to make sure deck is setting level. If not, adjust deck. NEXT. Make sure mandrel or shaft isn't bent or broken. (this is what you bolt your blades onto and top side is where the belt runs.) If you have hit a root or rock. These will bend and break. If so, Remove and replace with good used or new one. You can purchase the housing for somewhere around 25 to 35 dollars

Craftsman mandrel replacement::?????HELP


You dont have to drop the deck. Remove the belt first then hold the blade in place so you can loosen the nut on top of the pulley. after you remove the pully then remove the blade. There are 3 bolts holding the mandrel in place remove the bolts. Then pull the mandrel out from underneath the mower deck. There is a shroud that will come loose with it or it may stick from accumilated grass regardless it needs to go back during reassembly. When putting it back together the 3 bolts are usually self tapping into the new aluminum mandrel. Its much easier to put these in and take them out before you install the new mandrel as the bolts cut the threads.

Hope this helps
