RZT 50 left hydro not responding well.

[mastercraftka]

The right one is working fine but the left side leaks slightly and it seems to not respond well especially when cold. The tank has plenty of fluid. Any ideas. Can you rebuild those things?

Here's a couple threads I'd bookmarked

To save you some time on the first link, check out pages 4,5,9,10,11 -

Also, a loose drive belt will affect the LEFT side more than the right, due to geometry. Do a search under my user name in this forum only - somewhere I posted my experiences and a work-around for the square drive hole (you can't get to) for changing belts.

IF you can't find that post, let me know HERE - I'll see if I can either find it or re-post my fix... Steve

Just a quick response before i read and thanks by the way, but i did recently replace the drive belt which helped some but it was minimal.

Had a similar issue with the drive on my Huskquvarna ZTR but with no leaks. It was a loose bolt that holds the drive pulley on the spline of the hydraulic motor, causing that side to slip. Unfortunately by the time I found it the spline and pulley were ruined thus costing $800 cdn. I now check both drive pulleys every spring

Did you ever get your problem fixed? I have an RZT54 that recently had the same problem. I changed the hydro filters and fluid and now the mower is like new again! I would recommend trying this before you tear down anything.

I haven't done anything yet. Where is the filter located is there one on mine?

 

[warment]

If you have zt2800 hydros like i do, there is one filter per pump inside of a little plastic cover that has to be removed. My covers were packed with dirt and grass.

 

[mastercraftka]

So there is one on each hydro? Top? side? back?

 

[warment]

On mine, each filter is on the outer side of each hydro towards the back.

Try to find out if you have EZT hydros or ZT-2800 hydros. I have no idea what an RZT50 has. I have an RZT54 with a 24 hp Kawasaki.
