Hi folks,
This may have been covered elsewhere so forgive me if so, but I want to share an experiment I am doing. I have had trouble with my 1980's B7100 HST overheating when I'm cutting heavy, deep grass with my belly mower (deep as in mowing a grown up field). With only the thermosiphon to rely on, the old B7100's are prone to getting hot. This is alleviated by cleaning the radiator fins. To do a really good, thorough job, that has required removing the radiator and hosing it out from the engine side while it is lying flat on the ground. I did this years ago when I first got the tractor, and it worked well. A lot of gunk comes out. After that I would clean it as best I could while in the tractor but the gunk built up again over time. This year I had to replace the radiator hoses so I gave it a very thorough cleaning again and then ordered some thin fiberglass air conditioner filter material which I cut to fit and installed in front of the radiator. I got enough for $5 to cut two pieces and a scrap that just fits over the hydraulic fluid cooler. It just sits in front of the radiator, behind the screen. My plan is to rotate the two pieces when one gets full and then try to wash and blow out the one that is dirty. Yesterday was my first time for a big mow since doing this, and I had no overheating at all--I was concerned that the filter itself could cause that but so far so good. I'm curious if anyone else has tried this. Even if I have to toss and replace the filter when it loads up, it will be a lot better than having to pull the radiator. I'll put a link below to the filter material I used. It is very porous. Anybody else tried this?
