I have a Super Z that I just got and is my first zero turn mower. I was mowing and the right shift lever start going forward real easy and the mower acted like it wasn't going. It does it and then it seems like it goes ok for a little bit then does it again. I checked the belt and it looks ok. The lever moving real easy is what has me concerned that the pump may be bad. Can you rebuild the pump? Thanks for any help.

Don't know what number pump you have but a quick search does show pump rebuild kits for Hustler.
Seals and gaskets no hard parts.

Does this sound like the pump is bad? How do I find the type of pump I have?

It should have a BDP-21L-408 (PW-1LQC-EY1X-XXXX). But to be sure either look-up the IPL for you mower using the model number on the serial number tag or look on the pump for its model number.

If it is the BPD-21L-408 all parts are available from Hydro Gear.

Thanks. Where would the model number be at? Can I see it without removing the pump? Does it sound like the pump is bad from what it is doing.

To me it sounds more like something came loose in the linkages but I am not there to look at it. Your lap bar should still have the same resistance.

You should be able to see the number tag without removing anything but may need a mirror depending the location of the tag.

I checked all the linkages and don't see anything loose. It's not like it is completely loose. It catchs and then it just turns loose. Its like the pump isn't doing anything when it does it. It still goes but like skipping or something. It feels like a loose linkage though. Are the pumps very hard to rebuild? Thanks for the help. I wanted to add that what I am describing is with the engine running. With the engine off its like there is no resistance to the lever and the other side does have resistance.

It not for someone with experience but for a novice it can be a challenge. One of the main thing is a super clean area to work in.

I actually havent done one these pumps yet but do have on the schedule for after mowing season as it has seals leaking. This will give me time to be slow at disassembly and re-assembly; It always takes me longer on anything new I dig into.

Could the pump have lost oil and its low now ?
And I agree with Star Tech.
The area must be clean when working on a hydraulic pump.
Dirt and hydraulics don't mix.
Have rebuilt parts on Cat machines and know that.

I used to rebuild automatic transmissions in cars so I know about keeping it clean. I might take it off and try rebuilding it myself.

I checked the oil and it is ok. The left side is ok also and it uses the same oil reservoir.

I would think it has an oil filter.
I so, cut it open and squeeze the element out.
What do you see the the pleats of the filter.
Here's a video on rebuilding a pump. Use it as a guild.

Thanks. I was going to try to find a video on rebuilding a pump.

Here's one explaining the system.
Also if you're going to do this repair, clean the outside of the pump first before disassembly.
Clean is the key to this job.

I was trying it this morning and it seems like something is slipping like if the axle key was bad or something. I checked and the hub is tight. Forward and reverse does the same thing. It will go but like it jumping or something slipping.

Good luck with your repair.

Yes good luck with your repair/rebuild/restore/refurbish, hopefully everything will come out working good as it should.

I took care of the problem. I traded it for a brand new one today. Thanks everyone that helped me trying to figure out the problem.
