Major damage done- is my mower worth fixing, people?

People,

man, I crashed my MTD rider into a hidden tree stump, hidden with tall weeds. I went flying off , landed about 4-5 feet away, Im not hurt. But mower is hurt bad. One of the 2 blades got stuck into the stump, and of course, engine kept running and it chewed away the sproket end that holds/turns the blade. Sproket has disintegrated. How big a deal is it to get a new shaft/sproket/whatever one calls that part? Mower is old- 1998......has other issues too. Thanks,'people.

You need to put up the model numbers off of the tag under the seat, and better detail on the damage.

You going to fix it yourself? New or used parts? I would say price out the parts and then think what it would cost to replace the mower. You have all the answers for this not someone on a forum.

Thanks, guys. Fish, that Mod # is 13A4667 F118. Good to know Its just a mandrel, and its a doable job- as opposed to a major deal. Ray- I came to ask hhe;lp on this forum cuz you guys have always helped me in the past, and so far, you guys HAVE had some answers for me. Thaks for that. I never had any experience doing a mandrel..........

Briggs, I will study my manual but to remove deck, do I have to remove the belts/pulley first?

Don't bother fixing it until you write a book titled MOWING WITH COMMON SENSE . It may become a best seller.

Not funny, nor useful, nor gracious. I guess you never made mistakes in your life, or had any mishaps. Keep your personal judgement calls to yourself.

When you started the thread I thought you did a lot of damage. Just a broken mandrel is no big expense. If it was me I would remove the deck and not only change the broken mandrel, but also change all the bearings in the deck. This also will give you a good chance to give the deck a good cleaning and check for any cracks or other damage. Do the job right the first time, little more time and work but well worth it.

Senior citizen - we've all have done this he said it was hidden in tall weeds sometimes you just can't see these things until its to late. You should be more considerate to the people who come here looking for help, not trying to push them away.

To the OP I am glad your ok I bet you will find this a quick fix I would replace the mandrel, blade, belt. And definately inspect the other pulleys and mandrels for stress damage as said above if your going to have the deck off might as well give it a good cleaning and change the blade belt.

Geez, you guys are so inspiring- so generous for info/tips/encouragement!

So, now, I removed the 4 rusty bolts from under the deck that hold the "BLADE SPINDLE ASSEMBLY COMP", AS THE PARTS MANUAL CALLS IT (not sure exactly if thats what you mean by the "mandrel", or is the mandrel just a PORTION of that assembly(?). Since member above recomended to change out bearing, that implies I take apart the assembly to get to that bearing, right? (link/photo here of a typical assembly......)

MTD Spindle 618 0138 918 0138 618 0142 618 0138A | eBay

other thing- man, got the assembly pictured in link on bench, and cant get that pulley nuut off for beans! Sooooo tight! What kind of torque did they put that on with? I even tried to hold down pulley with chain "grips", and propaned the nut. No luck.

Thanks, people.

So what exactly was damaged? You can drop the shaft out by just removing the pulley on top and tapping the haft and bearings out of the housing, but if you don't have access to an impact wrench, you may need to rebolt the mandrel back to the deck and use a breaker bar.

I am surprised you got the bolts out without breaking them. Let us know what exactly is torn up, maybe put up a few pics before dark.

Right, Fish- its item # 39. They call it blade spindle (part 618-0138). The very botom of that has a toothed end, where the blade center fits in like jigsaw puzzle . Its stripped. I need a whole new assembly (part 39). Right? Part diagram you show does not show that assembly as a "come apart" piece- its the whole thing or nothing.......

Ohhh, I get it now. yeah, I understand, but sheesh- no way I could have gotten that pulley off while attached to deck! No wayy. (not that its any easier on the bench....LOL!)

LOL!! Right- I didnt explain all the details, but I had to break off the heads!!! Threads were apparently fused inside the threaded body of the assembly. Anyway, could mean that by default I have to buy new unless I drilll/tap/die. Probably too ambitious.......

OK, good deal. So that link to that item on e bay should be all I need(assuming I can get pulley off), Briggs?

sorry for late reply, brigs, but just to answer your question I ended having a budddy remove it with impact wrench.

UPDATE: got the new assembly, and only thing- the 4 holes are NOT threaded as my original one was. Should I tap them with a tap or simply insert 4 bolts with lock nuts on top?

Big thanks, fellow members!!

You are probably done by now but I would use stainless steel bolts, washers under the bolt head, and stainless lock nuts with nylon inserts. That will help prevent rust and vibrating loose.
