SCAG engine speeds up going downhill

I have a 52" SCAG WB Hydro. When going downhill it sounds like it is going to blow the motor. It revs up very high and when I go uphill it slows to a crawl.

Any ideas?

I checked the belts and they all appear in good condition. I haven't done anything else except drain gas and added fresh. One of my workers says it's the governor that regulates the power and it should be acting in the exact opposite way.

Could you be low/overfilled on oil? Some governor systems depend on slinging oil around to operate effectively, and when you take away/give it too much oil it could act wonky on you.

How steep of hills we talkin here? Handicap ramp or mountainside?

It's not normal at all. Even the slightest grade changes the way the engine acts. Uphill slows down, downhill speeds up.

I'm not sure about the oil thing. I changed oil and filter with required amount.

it is normal.

is it the way an engine should act? no

but it's the crap they make nowdays.

nothing is faulty with the engine. that's how they do when you go up or down hills.

even on my ztr if you push the levers all the way forward transporting down the road or something the engine revs way up. you let off it takes a few secs to get back to normal engine speed. it has done this since it was brand new.

I have this steep hill I mow and the engine will almost stall out before I can make it to the very top. the farther up the hill I get the lower the engine revs.

if it's just a gradual hill it doesn't do it as bad.

I think it's some kind of safety thing with the gov they've put on the engines.

Not normal. None of my WBs have ever done that. What year, model etc etc? Has it always done it or something new?

You'll get more help if you follow the guidelines for posting in this forum.

I think you may have a governor out of adjustment.

mine does it. it's not like overkill but it's noticeable the engine speed changes. it only does it every now and then. normal mowing it never happens. it's just on really steep hills or when going full stick which I never do while mowing.

kindof weird.

What happens when you disengage the clutch at full throttle?
