3k series Hydraulic/Drive problems
I've got a 2007 GT 3200 with front hyd lift and hyd deck lift , it's got less than 300 hrs on it , always been well maintained , and 2 yrs ago I changed hydro fluid and filter , oil is still like new .
All I really use it for is mowing and snow blowing . 2 days ago I was mowing , was fine for 5 hrs , then we started mowing ditches , not overly steep , but grass was thick , was working fairly hard , all was fine till I tried to push out another mower that got stuck , cub just bogged down and stalled , once we got unstuck , I continued mowing without a problem for probably 30 mins . Then I started losing my power steering and deck lift , I was now getting a whining noise when I tried to use hydraulics , then I also started to lose drive , sometimes it would do nothing at all , other times it would move but make horrible noise , I found if I turned motor off and restarted I could move again , this is kind of intermittent , in that sometimes I get nothing , and sometimes I get movement , and some hyd acc movement aswell. I know from other people's experience these machines suffered from exploding charge pump gerators , so yesterday I removed mine ..it's fine , no sign of wear or damage . Oil level is good . The pump does not appear to be making any noise itself , seems noise is actually coming from lines , im wondering whether I damaged one of the check/relief valves when I was working it hard ?. I've ordered a new filter, gonna try that first as that's just about the cheapest thing to start .
Any thoughts on this ?, I'm thinking if the pump is shot , it wouldn't work period.
