Been noting my L110 doesn't go as fast in reverse as it will forward,which to some degree I know is "normal",most riding mowers with hydrostats,they are set up so the linkage doesn't travel as far in the reverse position .
I had to modify the linkage on my old Yard-Man to get it to back up on grades after it got many hours on it and after I did that,it was fine,the transaxle was in good shape still..
Other riding mowers I've had did the same thing,older Craftsmen and MTD's would lose some pulling power & speed in reverse,and all it took to get it back was a little shimming at the pedal linkage to gain more travel to the control lever on the transaxle..
I think the same thing is going on with the L110--after 450+ hours of use,the pedal linkage probably has some slack in it--if I mash the pedal with my heel it'll back up faster and there is no slippage,so I think the linkage is to blame.
I had changed the oil to Mobil 1 15W-50 last year when I first got it and the old oil looked good,no metallic in it,it still looked clean...so I dont think its an internal issue...
Before I peek under it and inspect the pedal & linkage,does anyone have any experience with this,and if so,what did you do to get reverse to work better ?..I'm not familiar with John Deere's ,I'm sure I could figure it out after looking it over,but I thought I'd ask here first...
