Toro Groundsmaster 4100

I have a Toro Groundsmaster 4100 that will not flex the left side deck downward any more. It flexes up while mowing but usually will not go back down without hitting the lever each time. Seems like a check valve or something. Could someone give me an idea what and where to look? Thanks!

I'll tell you exactly where to look. The Toro website for a repair manual. That's a rather complex system to be trying to trouble shoot without a flow chart.

I have a manual and I see the flow chart. I am not understanding what would keep the wing from moving down when it doesn't seem to have a problem with going up.

I know little about the unit, but, is it a dual acting lift cylinder or a single?
If it's a single, could something be binding?

It's dual acting.
Troubleshooting says to look at pilot valve in lift/lower valve. I don't know what that might look like. Is it part of the spool?

Sorry, I don't know enough about the system to comment any more than I have.
Call Toro, they must have a dept that caters to their commerical line.

It's like the float in a plow. Part of the valve body. If your not sure, take it in

rod

the problem turned out that the cylinder rod was bent just enough to cause it to not move freely. I couldn't' see it until I took it apart and by the way that was listed in the troubleshooting guide as well. Thanks for all the help.
