Toro z master slow ground speed

[GREENOASISLANDSCAPING]

I have a 08 toro z master that seems to be running a lot slower than when I first purchased it. Anyone have any suggestions? I am leaning toward changing hydraulic fluid and filter. Does that seem to be a reasonable solution? Thanks in advance.

Tires worn down or low air pressures..

Can worn tires make that much of a difference

Sure...pump your tires up to 35 psi and see how fast it goes...

I would still change the hydro fluid and filter. the more volume of fluid that flows through the motors the faster the z will go.

I have changed the fluid and the filter, not much difference if any. I keep my tire pressure at 25 but I am riding tires that are almost slick. The smaller diameter of the worn tires makes sense that it would decrease speed but I cant imagine it is that much. Any other suggestions? Appreciate all the help.

I don't think worn tires would make a noticeable difference in speed. Have you checked the drive belt(s) for the hydro pumps?

Yeah the belt is a little wore but is still snug. I have a new one on the trailer. I guess I will put it on but really dont think it will make a difference.

Measure the height ..diameter..of the tire...multiply by 3.14....
Do the same with a new tire...3 or 4 inches of forward travel per revolution adds up fast..
Make sure your engine speed is properly adjusted..
