Hello everyone, this is my first time posting over on the cub side, and also the first cub I've ever owned. I have a issue with the hydro unit, I will first start by saying i have owned a john Deere 316 and 317 and i'm comparing the cub 1641 to them as far as the hydro control lever goes. The john Deere had a smooth motion from forward to reverse, The cub when going from forward to neutral or reverse to neutral comes to a very dead stop when it hits neutral, then slowly engaging in either direction is very aggressive, for example if in reverse and you move the lever to neutral, it comes to a dead stop flinging your body over the steering wheel, then you slide forward and it practically throws you over the back of the seat, and pops a small wheelie. Does anyone have any suggestions. Ps the hydro doesn't make any whine noises, or grinding, and does not creep while in neutral

I removed the cover over the floor pan, and the linkages are defiantly not sloppy, don't appear to be worn. If they were out of adjustment wouldn't the tractor creep forward or backward
The I sprayed some wd on each linkage, and particularly where two plate come together and pivot on a bolt, worked the control lever back and forth over and over and it seemed to free up the control lever without tractor running. Once i fired it up , it operates better but still not what I would call great. Another issue I have is the lever itself has been bent to stay in line with the forward slot, The neutral switch seems to be disabled,
I was able to get under the tractor and the spring seems to be there and tight by the touch of a finger I haven't pulled the seat pan yet to inspect Auto part Automotive exterior Bumper Vehicle

I haven't had a chance to try that out cubby1872 Ive had some other issues that needed addressed first. The PTO went to crap, ordered a new one and realized there wasn't a spacer on the old one between the block and pto. Ordered both and got it together then broke the belt, ordered a factory replacement which appeared to be way to large and sloppy, swapped it out for a shorter belt and seems to work great know. However the tractor is not charging with pto or lights on. I put a brand new battery in when i bought it so I believe that is why i am just now realizing its draining.
