weak hydro cub cadet

[325bob]

I read all the posts on the weak left side Cadet rzts,which is what I have, what I cant understand is why the left wheel is strong, can't slow it with a pry bar jacked up, but when on the ground, very weak, I already replaced the trans. with a "like new"one only to have the same issue. any ideas?

Did you replace the drive belt for the hydros, I’ve read that the left side pulley slips when the belt wears. And I would check the spring for the idler pulley FYI.

I tried a new belt, and actually moved the spring tensioner's anchor point for more tension, neither of which would explain why it works fine jacked up, but not on the ground?, update, I put some thicker oil in it, and it seems much better?, which still doesn't make sense?, I'm gonna put the same oil in the right side to try and replicate this anomaly? (it does have many hrs.1700!)

Long shot, but worth checking. Make sure the pulley on the hydroshaft in not slipping on the shaft under load.
