   I recently have been having problems with my Toro Greensmaster 3100, lift arms actually lifting. They worked a few weeks ago when I replaced a lift art and frame, but no longer work. The hydraulics are working as the mower will move along with the reels will spin, but won't lift. Hydraulic fluid is full and linkage from the pedal back is all connected and moving? Any tips or recommendations are welcome.
   
   Thanks

   Check the lift pedal,arm adjustment. The lift arm cam is adjustible and has slotted holes for that.
   Push lift pedal and check to see that the spool is moving fully
   Thats where i would check first

   There is a solenoid on the rear of the engine, (kind of tucked behind the muffler) it is responsible for keeping the battery charged. It's shaped like a box, with a red wire, yellow wire and I think black wire as well. If your not-lifting issue continues this is most likely the source of the problem. Have had this same issue happen a few time with different 3100's, everything seems to be working fine except the arms won't lift, it eventually gets worse, but i think that box on the rear of the engine could be your problem.

   Are you saying the voltage regulator is causing it not to lift?

   Do the lift arms lift by hand easily with cylinders disconnected (seized or tight pins in bushings )And are you using the recommended hydraulic fluid ?

   There is a detent valve located under the seat that faces towards the front of the unit. It has a straight screw head type cap on the front that will unscrew out for access to the inside of the valve. There is a spring inside which can get rusted up. Maybe see if your problem lies there.

   I would check the switches underneath the joystick.

   If your lift arms and pins are not binding and are free then I would check the spool valve travel at rear of valve for full travel if those are good then check for restriction in lines going to cylinder for lift maybe right in the fitting coming out of valve section and if that is good then you will have to check the pump section responsible for lift. The voltage regulator won't have anything to do with it on this model since it isn't solenoid actuated spool valve type unit. The detent won't have anything to do with lifting since that just holds it in mow. These units don't have a joystick so won't be that.

   I agree with Kipp Smith. Check the inside of the spool. You can adjust pedal sensitivity by tightening the screw head on the front, but I would open it up. Don't lose the ball bearings.

    Curios why you would think the detent would be the problem since it has nothing to do with the lifting and that is the problem All the spring in that cap does is put pressure on the beveled race with ball bearings to snap into the stud to hold in mow position.

    3100 with lift/lower pedals. not a 3150 with with joystick control. electrical has nothing to do lift lower on 3100.

    while a voltage regulator does not directly control lift/lower, when it is no longer working properly it allows the engine to run, but there is not enough to also run the reels and lifting of the reels. This has happened to us twice. the first time, i didn't believe it until the battery on the mower also died. We replaced the battery and that battery too died. that was when we replaced the regulator and the problem immediately went away. Not saying this is the source of the original post's issue, but, it was the source our our very similar problem.

    Yes Mathew that can happen on a mower with the electric solenoid controlled valves like yours must be but on this thread Ryan is talking about a 3100 that has a manual valve bank controlled by foot pedals so the charging system and battery has nothing to do with it and wouldn't cause such an issue. just saying

    Since you just replace the lift arm I would look at the bushings. If you didn't use OEM parts they could be too tight (I've seen that before) or it could be an air bubble in the hydraulic system (seen that before too). If it's the first I would replace them with OEM parts and if it's the latter you could just keep working it and eventually it should work out. Those are the only 2 possibilities I don't see already listed. Good luck.

    Sorry Karl, I totally missed the foot pedal mention!

    Disconnect the foot pedals and move the bar by itself that goes into the hydraulic control box. This should tell you if its out of alignment.
