So I got this yesterday from a old high school friend he bought a new one and didn't know what to do with this turd! It runs but loud and wont rev up! I actually drove it off my trailer. It steers good its in pretty good shape the hood isnt busted thats a bonus. It was really low on oil and there is no filter. He also told me he had to dig out pieces of the carb he thought out of the valve cover over 2 years ago I found that odd. and just mowed for a couple years till he got tired of messing with it. My question is im actually thinking about keeping it. Can i still save it? It doesnt smoke or knock. It is leaking oil up front the engine sounds loud either the muffler or maybe something else. It will be the cheapest chinsyiest mower i own. Im old school love my old ones. Does anybody have a gas tank for this gal? It needs a new gas tank bad. And how hard is it to change out the gas tank? Im in avilla indiana. Everyone Have a good week and good memorial day!!

It's a pain in the neck to access the gas tank. You have to remove the fenderdeck which is sandwiched in between the dash pedestal and the frame. Nothing that is difficult, just lots of fasteners to deal with. Definitely want an or cordless impact. I would remove the fenderdeck and gas tank, the hood [ undo the 2 springs and lift it off ] , the cooling shroud on the engine [ plug the carb inlet], and then pressure wash the whole thing.

Then install the new gas tank, new pick up tube grommet, new fuel lines and filter, new drive belt idlers, new traction drive belt if needed and then reassemble the back end. Hmm, might want to look at the steering gears while everything is apart.....

Then look at the motor. Surely needs a valve cover gasket and maybe a head gasket. Remove the float bowl and look in there. Remove the muffler and see if any baffles are rattling around inside it.

Then inspect the mower belt, it's idlers, the spindles, probably needs new blades..... The mower deck probably needs some welding on the rh rear bracket and probably several other areas......

Thanks for all the advice!! The deck on this one is solid no holes or brakes. I thought yesterday i felt grit in the oil. but after i get out of work today. Im going to start going threw it. I couldnt beat it for free!! and like i said i drove it off my trailer. I guess it pays to be nice to people. LOL I told the guy if he ever needs help with his new one give me a call.

Maybe bent pushrod not likely bent valve but more likely a dropped valve seat, all easy fixes tho... Also that's not the original engine. The 17.5 hp Kohler that came on the L series are great motors.

It was a bent valve i took out the pushrods they were a ok. i worked with a local guy who use to run a shop working on mowers. And that is the original motor. I had the guy who ran a shop told me so and here is more proof. TractorData.com John Deere L100 tractor information We could not get the tolerance for the valves. because of a bent valve. we took both pushrods out they were in great shape he also said they normally go bad first but this one was ran very low on oil and cause more damage then i wanted to deal with. I have better older equipment id rather put the money into.

Only the L110 came with the 17.5 Kohler. The L100 and L108 had the Briggs single. The L111, L118 and L120 had Briggs V Twins and the L130 had the Kohler V twin.

I stand corrected. Too bad it didn't come with Kohler Command.

These don't bend valves. They bend push rods (at least intake one), self loosen up rocker arm studs, rip and tear metal rocker arms, slip valve guides, pop out valve seats....but never seen a valve bend on its own.
You could hit it with a hammer and bend it but not common to bend one.
It probably set a long time and the valve stem stuck in guide and the piston smacked it and bent the head end. I didn't think they had enough lift to smack a valve even if open on compression stroke but lots of things are possible.
Used good heads are cheap and plentiful.
I would have that thing cleaned up and sold for 500+ in a heartbeat.
