74 hours on the meter and still fantastic. No new issues.
Based on my experience, the 50 hour service will go a lot faster if you have 24mm and 22mm sockets on hand. Also use a box cutter or Xacto knife to cut through the paint around hardware and filters where they seal against their respective components.
Regarding the oil drain plugs, the oil pan is a saddle configuration and the plugs sit on either side in a slight recess. The Welcome Box closed end wrench doesn’t get enough purchase to be useful the first time around because they’re painted.
I also found a suction fluid extractor to be useful although I removed all plugs/hardware as a final step. The extractor just made fluid transfer a little faster all around.
In my case, Summit was right to suggest washing the tractor before starting the 50 service. Obviously everyone’s situation is different.
While it’s not been below 20º here yet, and I’m keeping the TX25 indoors, I’ve got a Hulkman Sigma 1 pigtail installed on the battery and I plug it in most days. I’m also using a Kats magnetic block heater for about an hour on the coldest mornings.
I also just finished putting the HLA 1500 Snow Pusher together. I special ordered it in red so it‘s the last attachment/implement to arrive. Today, I drilled out the UHMW cutting edges and installed the skid runners, also UHMW. It’s ready to get go to work.
So, so far so great. I remain very happy with this machine.
