L2501 HST Treadle Adjustment

[Mak65]

I have a 2019 L2501, HST, with 300 hours. It’s not a speed demon but it seems lately it isn’t moving as fast as it once did at same RPM with or without load, especially in Medium (it has L-M-H range). I’m not talking bogging down or loss of power it just seems slower than before. WSM indicates top speed in M is 6.2 MPH. I clocked it using an app with a light load on front forks and an ever so slight rise. It indicated upper 3s to exactly 4 mph. At these speeds it seems even 1 mph is noticeable. Also, I don’t recall ever bottoming the treadle on the stop like I do now.

The WSM shows treadle linkage(s) but I’m not sure if any adjustments to any of it, and to what exactly, would increase the speed incrementally. I don’t want to throw off the pedal coming back to neutral for the safety switch, either.

Thoughts?

Check to see how you are doing with the Hydraulic fluid and filter changes.

I doubt it's the linkage, but you could inspect it visibly and look for any nuts that have backed out or bolts that hold the plates are loose.

Also, have you noticed a reduction of max RPM?

Is your parking brake on?

(I am not being a smart ass neither, many, many, many people have accidentally left it on, some for extended periods of time )

How is your Reverse speed? Has that changed? A lot of times if the speed changes on the pedal in forward by slowing down because the pedal isn’t moving enough anymore, then reverse speed will increase.

Is rear tire pressure low? If it's too low, there can be slippage between the tire and rim. If the engine/HST, etc. is all running normally but ground speed is slower than normal, that's another possibility..

if your like me i need to clean dried mud from under the peddle on a regular basis. this means i gotta pull mat up and clean in there really good. low hydro fluid level also contributes.
