    I just took my new Scag in for adjustments and because I was having switch problems and lack of power on inclines when using a sulky. Well they fixed the switch problems that others here have seem to be having as well as told me that Scag has been having slipping problems with their hydro WBs resulting in less power on hills when using a sulky. It turns out that Scag has come out with a fix to the problem and that it requires a spring to be added that my dealer said only takes 20 minutes to do. They are waiting for the part to come in so I have to take the machine back in again...arggghhhh!, but I'll let you know how it works out.

    Scraper, what kind of Scag do you have and what did the dealer do to fix the switch problem? Please see my post outlining the problems I'm having with my Scag. Thanks.

    The spring could only be for a tensioner pulley on the hydro belt. You could try a stronger spring and/or a new belt. Either way, the belt you have is slipping. You see, even on a hydro unit there is a belt that is going from the crank shaft to the hydro motor and if it slips then it needs some more tension put on it or replacement.<p>If you get down and put your face under the frame looking up, you'll see what's going on.

    OSC...Close on the belt idea, but actually it is the springs. Supposedly when the hydro is under extreme pressure like on an ncline the naturally tendency is for the fluid to go the path of least resistance which means back to neutral. What they did was put new springs on both sides. Heavier springs. The unit pulls me up hills with power now! Granted...it is a little bit tougher to squeeze the grips, but big forearms help for fall cleanups. The belt had nothing to do with it at least in my case. My first thought was the belt as well as needing additional fluid, but these springs did the trick! My Scag is the 2000 52&quot; with the 17hp Kawi and Advantage deck. <p>As for the switches...I shouldn't have spoken so fast as I went out in the field on Friday after it was supposedly fixed to end up having more problems! When I took off the parking brake the machine would shut down. Needless to say I had 10 to cut and I wasn't taking it back at that point as the dealer was 30 miles away so I called and ended up cutting the wire which overrode the entire safety switch wiring harness. Not a smart thing to do, but I had to get the lawns done. Took the machine back and now it seems to be working. The mechanic that did the work said there was a rubber bootswitch that needed to be popped...gets me...when it comes to electrical systems I'm all thumbs. Excvept for cutting that wire...felt like I was defusing a bomb. Cut the wire and prayed for the best.

    Scraper,<br>Do you have the part # for the spring(s) that dealer installed for you? My dealer /service tech. doesn't seem to understand what I'm talking about. Thanks,<br> SKDCO

    Ah, springs on the triggers, yes that would do it as well.

    SKDCO...actually no I don't have the part number...I will try and call today, but if I don't get back to you, call my shop...they have a toll-free number...800/315-2966...it's called Suburban Lawn & Equipment and the mechanic who did it for me was named Glenn....hope this helps!!! Let me know if they help you out. They are great guys there! To add to my last post...you won't believe the power it has in reverse now as well!!! Not that you should be going backwards all that much, but when you have to faster is better. :)
