I've had my machine for around 3 yrs and have just replaced the tired old Kohler with an Onan 20 hp. I was able to use the original sheave drive by using a sleeve on the shaft only now it will only be manually adjustable. I have a new pump on the way which I'll drive with a pulley. After the first yr of use the hydraulics began to jerk bad and I'm not sure of the cause. I'm using hydraulic fluid from tractor supply and the filter that bobcat recommended. One of my manuals said use Hydro fluid and the other said ATF. While I have it apart I've prettied it up a bit and will replace some hoses, I'm wondering if I should clean out all the fluid and use the ATF which will be pricy unless I can find it in bulk. Also the tires are two different sizes, 1 1/2 difference in height being that the machine skids by design I'm guessing that no harm is being done?? The gear case is in good shape and I replaced the clutch discs when I got it. Thanks for any help.
