Hi folks,
This is my first post. I have a big dog alpha MP, which is a re-branded hustler 54". I changed my oil and filters today in the two hydro gear 2800 units. I missed the 75-hour mark by a bit. I am at 89 hours currently. I followed the instructions for filling and purging. I used Castrol GTX 20W50 (conventional oil). When I drained the oil, it was cloudy, so it probably did need changing. However, after purging, I cut my grass for about 15-20 minutes and BOTH hydro gears went out suddenly and simultaneously. It was as if a switch had been flipped turning off both hydro gears at the exact same time. I was actually done mowing and returning to its parking place and didn't make it back. I tried doing the purge a second time, but never got power back to the wheels. As an information item, I didn't prefill the filters as it didn't say to do that in my service manual. I just filled until oil ran out both holes at the top of the two units. I used Stens filters, as these were the ones available at my local mower shop. I wondered if I need to open the vent holes again and see if more oil goes in. Currently, there is oil in the overflow tank (only one overflow tank on this mower). I also thought it might be overheated. The transmissions were pretty warm to the touch, so I let is sit for an hour or two and tried again...nothing.
Any ideas?
