Toro Wheel Horse GT 550 Slow in High Gear

[Pattyb 17]

Good morning,

I am hoping someone can help me because tractor repair is not my area of expertise but I can research, read and follow directions.

 

I bought this tractor about a year ago and it does not achieve full speed, full throttle-high gear speed is the same as low gear, but it flies in reverse. It has 500 hours and I changed the oil and filter, I didn’t clean the power steering filter because all of the posts that I’ve found, this is never the solution. We disconnected the smart steer in the spring using a method found on this site but that didn’t help; it only prevented it from slowing down more while turning and that’s a good thing.
 

Today my husband is going to help me check all the pivots and linkages but like I said, I can research and read and think the problem lies in the neutral adjustment. I was just looking at the 5XI SERIES TRACTOR HYDRAULIC SYSTEMS SERVICE MANUAL and saw a note about the pivot point and went to look at mine, the machine is not running and the pivot point look like it is facing the wrong direction. My questions are, am I correct that when you don’t have any pressure on the accelerator the pivot should be facing the other way? Can I change this while the tractor isn’t running? I realize that we should do it while it’s running to avoid creep but I took it apart so that I could clearly see everything. I am trying to avoid guessing and making it worse, that’s why I came here. Finally, since it’s apart, is there anything else that we should inspect?

 

Thank you in advance for helping a novice.

I am not very knowledgeable on the newer Wheel Horses but some of our members like @Pullstart or @JoeM may know the answer.
