I just picked up a few to good home Exmark Laser HD 23HP Kawasaki with 48" fab deck and has 740 hours on it. It has Hydro Gear 103-1942 hydraulic pumps and there are 2 hydraulic wheel motors. I'm new to screwing with zero turns and hydraulics, but here is what's going on.... from what I see, 700 hours is nothing on this commercial piece. He says that he paid $8500 for it around 12 years back. So it isn't a junk consumer one.
You start it and it runs and mows 100%. Life is great for around 15-20 minutes, and then you'll notice it slowing down and not pushing up slopes. By 25-30 minutes, it's done.
Let it cool off and it will repeat.
He chained hydraulic filters and got no change. He used OEM filters and also gave me another spare set of 2 hydraulic filters.
How can I test and verify motors vs pumps? Pumps are $1200-$1500 each while the wheel motors are around $400 each. He says that the left wheel gets weaker faster, but both eventually die out.
