I have an RM830e and a John Deere R72. The R72 has an actual transmission with a chain that goes to the rear axle and a pulley on the bottom that's connected by a belt to the pulley on the crankshaft on the engine, and I like that setup a lot more than this.
I don't care much for it. But I never had one in good shape or never repaired one. I'm sure there may be a gear version out there. It's like this though I would have to see to understand it. Thanks for watching Paulie.
