I've got about 2 mowing hours on my 52/24 mini and I have a few questions for Pj. First, I noticed yesterday that I had a small leak (very little) coming from the right hand side of the machine at about the middle of the mower. I checked again today and there were another couple of drops. Turns out that the hydrostatic oil filter was not sealed tight and the filter was a little oily. I hand tightened the filter and cleaned it off and checked the level in the reservoir and it was 1" from the top. Assuming this stops the leak, and I'm sure it will, are there any concerns about the filter being loose will I was mowing(thinking about dust)? Second, will mowing in some taller fescue with the deck set at 3.5" , it seems that the mower leaves a few of the taller blades of grass uncut. The deck seems to be level as far as I can tell. The blades only have 2 hours of cutting time on them. Any suggestions? Oh, by the way, I'm in love with this mower!
