I have a Turf Tiger model STT61V-27KA. This season hydraulic fluid (oil) has been coming out of the cap every time I mow. I have not noticed any issues or anything unusual with steering. It happens about 20 minutes into the mow and is a continuous “bubbling” out of the cap. So far I’ve replaced the cap, changed the oil and filter, and ensured that there was no air in the system. I don’t notice any air when I check the oil after I mow, but the oil is always about 1/2 inch below the full “hole” by the time I’m done. I guess I should also add that no, I’m not over filling. I’m at a loss. I would think a clog would result in steering issues. Thanks for any guidance.

Sounds like the oil is over heating. Check and clean the oil cooler for the hydraulic system.
Thanks. Outside is clean - that’s the only thing I really know how to check on that. I guess I’ll be taking it in, but at least if it’s that it doesn’t seem too expensive. I appreciate your time!

As long as you are using it to clean the outside. Get the non-chlorinated version.
Simple Green HD is another good choice.

MParr- Yes outside only.. Was concerned about any seals etc.. My HG 2800's do not have the external fluid reserviors, like they used to. But have a sintered type Breather / filter on top of each unit...
As well as fill cap nut & full level bolt hole too.
Getting pretty hot, so making sure all is clean & running as cool as possible.
The Turf Tiger has a reservoir on the LH side above and rearward the wheel. The unit uses two BPD-10 pumps and two wheel motors. The oil cooler is behind the seat and in front of the engine. It can get clogged with dirt on the unseen side. Basically the only oil cooling is this radiator as the rest of the system is just surface heat radiation.
How about some good old fashioned engine degreaser and a scrub brush? I know you real mechanics want it done as fast as possible..... LOL

Personally I use a couple products to clean with air driven engine cleaning wand. One is Purple Power de-greaser and other can be a dangerous but is safe if you take the needed precautions. That one is 2 cycle fuel mix. I use the 2 mix when I have extra stubborn baked on grease that the Purple Power de-greaser can't cut through. A brush would help but there places that one can't reach easily.
Now I haven't read the brake cleaner ingredient list so I don't what is in it but may contain rubber damaging chemicals.

water in oil will cause foaming and overflow. So will overfilling or overheating.

Mine are all clean now. I just used my air hose with rubber hose extension, & 1/2" paint brush. No chemicals, DRY clean.. Easy as it is only 20 hours from BFN..
