Exmark Shakes/ Shutters Under Load

I have an exmark laser that shakes or shutters when I start to pull from one side. If I'm going up or down an incline and I try to left steer front of back it shutter and will barely pull. No problem turning on level ground only when its under a load. Any advice would be appreciated.
Thanks Ray

I'd guess a wheel motor, if it is only doing it on one side.

Sounds like a wheel motor. Better get it looked at before you trash both sides with metal filings in the oil.

I bought pumps and wheel motors from J Thomas Catalog and saved money.
But make sure that is the problem first.

the reason i said the hydro pump is thats what happened on my older scag turf tiger. i bought a new pump online and had a mower shop install it for 100.00. they installed it faster then i could have. take it to a shop to make sure, like others have said.
