Does anyone know how steep of a grade i can go up with an exmark quest zero turn. I have a hill thats 20 degrees or so. Will the machine get up it or do i have to mow side to side. Haven't bought yet but looking to soon.

I'm a go by the manual guy and according to it you should never mow on inclines with a slope in excess of 15 degrees ( a rise of approximately 2-1/2 ft every 10 feet) and you should always mow across the face of slopes rather than up and down and you should always start at the bottom of the slope and turn up hill at the end of each pass when possible.

I for the most part tend to go by the manual too Ric. And i also read that 15 deg was the max. But can i push it a little (5 deg) without getting into trouble like with oil flow?

Some of the Kawasaki engines will mow up to 20 degrees. My Grandstand can mow up to a 20 degree slope. If that has the Briggs I don't think I'd push it past the 15 degrees to much or an extended period, but that's just my opinion.

Wanting to push your luck with a $3000+ unit seems pretty risky to me. If it's a new unit you could even be risking voiding your warranty. In my opinion it's not worth it.

Yah Ric, it's got the Kawasaki engine. Someone else makes a very valid point about the warranty being voided. I'll have to reconsider my options, and my wallet. Thanks

You make a good point Rivets. I'll think more on it. My hill isn't all that big. I thought about a walk behind and that may be another option. Although still not sure oil pressure would be ok at 20 degrees. I'll talk to dealer. Thanks

Yes it is a valid point and he is right it's not worth the risk and you also said you were going to talk to the dealer which is a good choice, see what they say I'd be interested in there answer.

Just as a follow up and according to Kawasaki my GS engine in there words, this engine will operate continuously at angles up to 25 degrees in any direction.
Do Not operate engine exceeding angles of 25 degrees. Engine damage could result from insufficient lubrication. It should be listed under Engine Inclination in the operating section of your motor manual.

I would not go over 15 degrees unless I have a ROPS system and experienced with the machine on slopes. The engine may be able to handle the slope, but can you and the rest of the unit. SAFETY FIRST!!!

Yea I agree although that's what the engine manual says, the mower manual says 15 degrees nothing more and like you safety should come first.

If you're question using a ZTR on a slope/undulation - IMO the simple answer is you most probably shouldn't be using a ZTR there.......once youæ±*e approaching the maximum machine gradeabilty, any relatively & in most situtaions minor equipment failure especially a tyre deflation can lead to catastrophic results

IMO, quite why a ROPS is required on a ZTR is interesting, sure there may be legislative requirements & you can mandate all many of safety firments but this all seems a nonsense given if you're using a ZTR in a situation where a roll over presents any real danger you've exceed the design intent & capability of the ZTR, & more than likely the operator skills/instinct for self preservation .......all a bit like fitting a parachute to car in case you decide to drive it off a cliff........
The fitment of a ZTR ROPS IMO merely encourages false confidence/compounds "misuse" in terrian where it was not designed to go ....in these circumstances perhaps alternatives such chemical control, possibly using a 4wd CUT, or landscaping that hillside grass area is the better choice....

Consider also in reasonably flat or lightly undulating garden environment, a ZTR ROPS is potentially a far greater hazard/risk due to overhead "hand ups" & "back flip" than its original design intent of a supplementary safety device.

It's not that I am against ROPS or safety investments, in fact on our farms I would not have any tractor without ROPS or indeed any self propelled plant without flashing beacons, reverse quackers, seat belts ..etc (& have dismissed farm hands for not embracing safe practices such as mandatory use of seat belts irrespective of the terrain).
I'm sure others will have different perspectives .........

On the consumer reports video they advise not to use zero turns on slopes higher than 15%.
