Everything was going good this last week. Went to use mower this morning and I had nothing on the side I replaced the pump. I thought it might have had air in the system so I put it on jack stands and bled the system.

After bleeding it worked okay but when it would cool off say in between jobs ( more than 20 minutes of not running ) when I would go to take it off the trailer I would have nothing on that side and then it would "kick in" and be fine the whole time on that job.

Still thinking maybe I hadn't bled all the air off when I got home put it up on jack stands and put it to half throttle and full stick for 30 minutes. After letting it sit for an hour got the same thing. No response from that side when I would first move the stick then it would take off.

What is my next step? Wheel motor going bad?

Greg..is there any foam in the tank or leaks on the ground?
Any metal in the tank....is the pump groaning...
I guess it would be possible to have enough play in the wheelmotor to create a deadspot when it is parked...just guessing...if this were the case..the wheelmotor would probably struggle on hills when warmed up..

When I went to use it this morning I could barely get it off the trailer and then put it right back on. No foam and no leaks. No metal in tank. The pump isn't groaning or anything. I just replaced the wheel motor, fluid and filter and all seems normal. As to the hills don't know, don't have any real hills on any of the properties we have.

I replaced the pump 10 days ago. The wheel motor just a couple of hours ago. It was having problems going up the ramp yesterday.

Thought all was good this morning first job was okay. Went to take it off trailer on 2nd job no response on same side, then pump was louder than normal and it started to respond. Mowed whole job, seemed "jumpy". Checked fluid, lots of bubbles / foam. Seems I'm getting air in the system. I did not replace the o-rings as none of the dealers had them. The o-rings looked flat almost like plastic. The parts diagram shows them as flare 37 8. Could I get these from say Napa?
Any advice would be great as my back is against the wall once again.

Looks like the high pressure hose I didn't replace has a super small leak around where it is crimped.

If the orings were leaking...they would make a mess...high pressure hoses would spray..
Did you put hose clamps on the bypass hose tee...Exmarks will suck in air if these hoses arent tight...and they wont leak fluid..
Did you have to inspect or change the rotation of the charge pump when you changed out the pump ? ...a damaged or missing spring atop the ball could give intermittent problems..
You have a stubborn mower....
