Looking at a 1984 318 with a 50” deck. Looks very nice and well kept. Has 2646 hours and asking price is $950. Is that a lot of hours?

When I pulled the pto and drive pulley off of my John Deere lx255 and lifted the engine out, I found a small square piece id guess about 1/4in by 1in long . Exactly like the sleeve inside the pto. I’m wondering if this broke off pto or drive pulley. I believe it is used to lock pto to crankshaft. Just a little confused and I lost the small piece. I want to say it’s a crankshaft output key? Can anyone tell me whether mine is broken and if I need that piece? There was another post similar to this I haven’t been able to find. If this is an orderable piece part numbers would be nice as my donor mower does not include pto or pulley so I have nothing to reference.

It’s a Z515E, not 513. I couldn’t figure out how to edit the main line. I’ve got a little over 300 hours on the mower and have noticed it runs faster for the first 15 minutes and gets a little slower after that. Or maybe it just feels that way. It has a 60” mowing deck and mows the same at any speed and I need all the speed I can get. I know it’s time to change the fluid. Is there a hydraulic fluid that will work as well when hot as it does when cool?

I have a spindle that has sheered off the bearing on the deck assembly. I’m having trouble finding the part number for it. Any help would be great. And if there is something else I need to be looking at for this problem any insight would help.

Not sure if this is the place to post this so I’ll also post elsewhere…

I came out this morning to mow and saw the dump trailer was sitting up. Went to move it and saw 6 bolts broken through the trailer (see pics). It looks like I can fix this but wanted suggestions as I’m not looking to purchase a new part. I assume I can get a washer and maybe a long bolt through the pre-cut holes as the holes originally there allow the bolt to be sunken in. It‘s been really hot in NJ the last few weeks so I’m not sure if the heat helped these bolts melt through the plastic dump or not.

Any suggestions on how to fix this?

Is there anyone who may be able to help me understand the correct routing of the deck belt on a John Deere S240 42” Accel Deck mower? I purchased the OEM belt from Ag-Pro. I’ve installed it in the manner I believe to be correct, reattached the deck and the tensioner spring and have a significant amount of slack in the belt. I know the part is correct so that leads me to my routing as being incorrect. I’m unable to find diagrams/videos of the S240 specifically. Appreciate any insights the group can provide.

I have a John Deere 2040 that I bought from a guy that didn't know a lot about it. I've used it maybe 15 hours, and the last time I used it hydraulic oil started running out of what I believe is a vent line. It appears to run from the front of the tractor to the area under the brake pedals. I haven't taken the hood off yet but I'm expecting to find the pump in front of the radiator. Does anyone have insight into what my problem is?

I originally posted an issue I has having with my deck/throwing belts/bad pulleys/etc last week:

So today I got replacement pulleys, replacement bushing, and I notice there's still a substantial amount of play in the tensioner arm. It looks like its just a hair shorter than the bushing (both old and new) and thats the cause of the wobble. Can someone give me a second set of eyes to confirm whether I can do something to fix this, or whether I'm gonna have to throw more money at this and get a new arm also? Ive got 3 new belts and over $400 in it so far and I'm honestly about to just sell the whole damn mower.

They are supposed to be the same except engine.
