I have a 700-070A Peerless transmission on my '05 36" Toro Proline belt drive walkbehind. Sometimes (not always) I hear a chattering sound come out of the transmission as I am mowing. I have not had it act eratically (no stopping or rough operation) but the sound makes me wonder if it is going to need some repair (shifter keys?). It goes up hills well also. Could it be that I don't always have the shifter lever positioned properly so it is not engaged right? I called a local shop who says it would be about $100 to replace the shifter keys. He also said to not wait too long as more damage could be done by worn parts. I can buy a new replacement transmission for $175. What are your thoughts? Let it go for now? Repair or buy new? Also, how hard are these to remove and replace if I would want to do the work myself if I replace it? Thanks

i don't have one but just thinking out loud - - - I'd run it till it died and replace it - $100 and that might not fix what you're hearing anyway - if it aint broke . . . put the $175 aside for when it does . . . if it ever does - and from what i have seen it does'nt look like a real tough job replacing a gear drive tranny - i could be wrong - I'v never done it - but it does'nt look to tough

Since you state it doesn't jump when making this noise you may try adjusting the shift detent and see if this solves the problem.

Reference number 21 (below) on the top case half is the adjuster, Rotate it in 1/4 turn and try it again. If it still does it try another 1/4 turn, If still no improvement it most likely is worn shift keys.

If you can get a new trans for $175 that would be the way to go.

Time to replace one depends upon how easy the drive pulley comes off and if the bearing set screws on the drive shafts don't round out.

If you are going to keep your walk behind (and especially if you have a sulkey) It would not be a bad idea to have a spare trans. I have one spare that will fit on either of our walk behinds. it gives me time to make a repair and can be switched in about 1-2 hours.

Thanks for you replies. I will try the adjustment and may go ahead and buy the spare tranny.

Let me give you my advice on the peerless:

At $200 a pop and a good afternoon worth of work JUST to replace it with a new one, you have to decide if it's really worth shifting that dang thing, it ain't like a car, they're tough and you can shift them but also on a bad day you miss a gear once and...

So unless you're fond of rebuilding these, what you do is select ONE gear and use it exclusively, you do not shift a peerless, adjust speed with belts and don't worry because they won't wear that fast either. No don't even use reverse, just don't shift a peerless, pick a gear and stay in it forever.

That or get a Peerless Repair manual from J-Thomas, then order a spare 700-070 and make sure you get the right one because there are several... Then when it breaks you replace broken with new so your mower is working, and keep the broken someplace until you get a chance to rebuild it.

As for the clicking...
When's the last time it got greased?
Careful when you do this because the case is aluminum (NO air tools!).
But take the cover off, you can do this while it sits in the machine, because maybe it just needs some bentonite.
When re-assembling, you'll need to get some gasket in a tube and then be real careful when you re-tighten up that cover.

btw when mine acted up (and it did it for a long time before it crapped out) it was the needle bearings that hold the vertical shaft down to the belt pulley (parts 12, 24, 27, 28, 32 or so on the diagram). I would keep on driving it until it breaks, it could be anything.

all we run are toros and thats 21 proline 52s.all are equipped with the peerless tranny.before you do anything else pop out the plug in the top of the case and fill the gear box.remember you never ever shift one of these trannieswhile moving.next reach under the unit and check the pulley and shaft to see if there is play there.i personally rebuild our trannies but unless you dont have anything better to do just buy a spare and shelve it.

working on the peerless trannys is a pain the A$$ from my experience. the manufacturer for got to install the fifth gear on a poulan pro garden tractor!

i do, and they are not hard to do at all. well for me, i went to the fearless of peerless school back in the late 80's and they have not changed much since then. just a gear drive transaxel. i live in east TN. these mountains are hell on those things. main thing is to be sure you have the bronze bushings in the right way. there is a small tit on them and the will only fit one way. try to put them together any other way and the case will break or they will lock up and not move at all.

Ive got a similar problem with the peerless transmission on my 48" encore, but on mine it only chatters when the mower is coasting not when it is pulling the mower. Is this the same or similar problem? and should I use the same advise of wait it out as stated earlier. Thanks

I have replaced several on our toro belt drives, they are relatively easy to replace if you have the right tools (forklift or engine hoist is a plus because a floorjack gets in the way) As stated above, check to make sure they are greased and bolt tightness is as proper spec.

Sometimes you get a stack up of tolerences that can cause noises. It could be nothing but any chattering should probably be investigated. It doesn't do you any good to be broke down. If this is a money making piece of equipment for you I'd spend the $175.00 and buy the new tranny. Maybe keep the old one for a back up. $175.00 is a great price and is well below dealer cost.

Go on Ebay, I think it was Russo Power Equipment that was selling them. They are a big dealer up in that neck of the woods, and I am probably going to buy one for my 36" Scag for a backup. I was looking at them last night.
