LTH 130 hydrostatic problem
Hi, I'm new to the list and have a question about a Husqvarna 130 LTH hydrostatic mower. This mower runs well for 10-15 minutes, but as soon as it's warm the mower hardly moves when in gear. I had it to a mechanic, who said he couldn't find anything wrong....rode it around the parking lot for 10 minutes or so and tried each gear.When i got it home and ran it for 10 minutes while mowing it loses power....the slightest incline causes it to stop.Is the problem with the hydrostatic part, the transmission or perhaps the belt drive?? It's in excellent shape, and I'd like to fix it if possible. I've been told this vintage mower probably has worn out the hydrostatics and it's not worth replacing this. Any help would be appreciated....I'm getting a little frustrated.
