Ok sorry for the bad quality of the image.

Calling all GTC (Greens Tender Conditioner) EXPERTS!!! Anything look odd with this picture? Should the Collar Gear (on the left) have the same length splines to the right gear (whatever they are called)? The 2 rod looking pieces? The engage the GTC drive from the on/off lever.

I am having a hell of a time installing this back to the mower. I removed A LOT of old grease and I spin the reel with the GTC lever on but nothing happens. I have the lever in the collar gear grove so it move back and forth.

Any iseas?

I don't see the brass coupling that goes inside the part on the right. That's the slip piece that makes all of this work.

Of course... John Deere doesn't list this with a part # on the parts catalog. Anyone have a picture of what it may look like?

I wanted to buy just that part. They don't seem to sell it. I took dimensions to find a similar one. I have them at home.

In my rebuild I took pictures of it. It is a wear part and it seems that it is only sold with the gear ($$$$).

Nice! My shift collar gear is definitely worn down! Welp another $80 part.

Any images of the final assembly? I see the brass fitting goes between the gears? Or does it sit behind the engagement gear with the snap-ring?

These are for the 220E. From looking at other GTC they look similar in design.

I have a ton of more images. I will post them later.

The brass bearing goes inside the sprocket. It has an internal oil groove, but I'm not sure why they did that since this uses a thick grease.
Image

The sprocket goes into the shaft after you place the two sealed bearing on the end with a washer in between. This sprocket is always turning when the reel turns. The brass bearing seats against the inner race of the seal bearing so the sprocket cannot touch the sealed bearing.
Image

The other sprocket then is using the shaft star pattern to turn and it slides forward or back using the on and off knob.
Image

When the knob is in the on position, the two sprockets connect to turn the groomer shaft. When it is in the off position, the sprocket on the right turn and it slips under the brass bearing and the shaft does not turn.

When I took apart the GTC... I was missing the brass fitting, brass washer, and snap ring.

I have a standard size washer that is 1.5 inch diameter. It needs to be a slightly smaller size but I can't find a hardware store that carries metric washers this big.

Hi Guys, I'm just getting into the lawn scene and getting a reel ready for the spring. Put down 3100sqft of zeon zoysia 7 weeks ago and gave a it a trim with the rotary to even it out a bit before it goes dormant in a few weeks. Little later than I would have liked but here in GA its taken root pretty good in that time. I've been working on a back yard renovation and still have some patio work to do. Then in the spring will get around to leveling and soding the front.

I picked up a 2500A ($300ish) from a gov. auction a few years ago in anticipation of a new lawn and quickly realized it was going to be way to big. Not to mention storing and maintenance of 3 reels. So I picked up a 220A of CL for a good price, I think it was around $250-$300. Its been sitting for about 2 years as well but I swapped the carb and fired up 2nd pull. Ran it around the yard some with the reel disengaged to maybe help get some bumps out. Some leveling will still be needed.

However I stumbled upon an gov auction for some 220E's minus the reels from a course and figured I'd take a chance on them. Went and picked them up today. Some are more complete than others. Made in 2009. They kept the reels to swap onto their existing ones when one of them needs sharpening. Less down time on the mower which makes sense. So hopefully I can find a decent deal on some QA5s I can swap in and hopefully sell 1 or 2 complete to make up some costs. If not then parting out might be an option. So we'll see. Either way I'm excited to be here and learning as much as I can to keep this zeon in great shape.

So now that makes 5 walk behinds and a triplex reel mower :)

@claydus

When I was rebuilding the 220E I could not find my caliper. I used a paper to trace the OD, ID and length of the brass bearing. I now measured it from the paper as 20mm OD, 14mm ID, and 24mm length.

@g-man any recommendations on where I could start looking for a brass bushing like this? Found a few by googling “John Deere brass bushing.” Also found a bronze bushing as well

I found 1 with part number M45204

This is the closest I could quickly find, but the length is too short. A local machine shop might know how to find this locally.

Found this but 4mm too long. Seems cheap enough that I could attempt to shorten it.

@g-man I thought my brass bushing was missing from the GTC sprocket. Today, after wiping it down thoroughly I saw a faint color of brass inside the sprocket. It worn severely wedged inside the sprocket. It was only about 2 mm thick. I was able to pry some of it out and then drill the rest of it out today.

Here is what left of it that i was able to pry out at the very end.

I got my chinese brass bushing from Amazon yesterday. It is slightly too big even when put in the freezer. Looking into options to drilling more out if the sprocket and sanding/filling down outside diameter down

heat the sprocket with a torch as well as put the bushing in the freezer. you can always put it in the oven (i use a toaster oven) at 450 if your not comfortable torching it. Or just take it to be pressed in.

@claydus Did you measure the brass bushing and the sprocket? I dont recall it being a press fit. @Pete1313 Do you remember?

Also, looking at your sprocket, it looks different than mine (see images a few post above).

Yours definitely looks brand new. Mine is for a 220B not sure if part is the same. The 2 teeth that engage the other gear are worn down a bit. Also your brass bushing looks quite smaller in wall thickness.
