2006 Cub M60 Tank leaking hydraulic fluid, video
 

My 2006 M60 Tank (made by Lesco) is leaking hydraulic fluid. I've had this machine since 2007 and it's been a great mower. I use it on my own residential lawn which is about 2 acres, has about 500 hours. The thing has been solid as a tank and and no real issues. Today, I could barely make it up a hill and knew something was wrong. I don't have a good mower shop around that's trust worthy and wondering if this is something you guys can guide me with on what to check. Thank you!

I would start my trying to pin point the leak. Clean that area up with "Brake Clean" to where there is no oil residue. Then periodically watch that area for new leaks. It could be coming from the Pulley Shaft Seal.

Check your Hydraulic Oil Level, top it off, and monitor.

Post your model + serial# and what engine and deck size. Cub doesn't show anything like what you pictured but parts tree has a bunch of "Tanks" and I have no idea what you have. This Lesco deal looks like a typical MTD deal like when they sold Sub Compact tractors made by other company's. I suspect as Roland mentioned that you have a pump seal that has seen better days.

I had a Lesco ZTR several years ago and needed parts. John Deere purchased Lesco and it was impossible for me to find parts. As others have said, list your model number and I would also see if you can find the model & serial of your leaking pump too.
