I've got 2 YT3000 with no or very little reverse. Any fixes? Or is just plastic junk?

How does the belt look? Post the units model and serial numbers, located under the seat. Might just need a belt and a couple of pulleys.

The belt is brand new. With the rear end lifted and the wheels off the belt is turning the trans, but as soon as a load is put on everything stops

We really need the model numbers off the two mower from the serial number tags. As when I tried looking up the mowers I came with three different transaxles being over the years and RS800 wasn't one of them. That don't mean the RS800 wasn't used, it just that I may have not found the correct IPL.

Also just because belt is new doesn't mean all the plastic idler pulleys are good. The V-idlers are especially prone the wearing allowing the belt to bottom out in the groove and effectively lengthening the belt. Also you need to install the correct length belt for the model you are working. As I said there is at least three different drive belts used depending which transaxle used.

I ran all the external tests and it does not turn rear wheels as per reverse function test. Its hard to turn and only one wheel wants to engage.

Did you replaced the belt with an OEM or aftermarket belt?

There is two drive belts. One from the engine to the transaxle and the one that actually is on the transaxle.

Now the 197253 (532197253) is listed as 1/2 x 100.97". This belt was superseded to 592855001 which is 1/2 x 100.25". Also I have seen both v-idler to wear out on this system causing belt slippage under load.
