I have a B7100. I use it regularly to mow my 3 acre lawn. Last year I was able to pick up a 40" brush mower to manage my small pasture.i recently hooked it up and mowed for a bit out in the field.
After about a half hour I put it in the barn. After shutting it down I heard a steady bubbling noise under the center of the tractor. I thought it sounded as if it were coming from the hydrostat trans.
I thought, oh no! I overheated it somehow!
Strange. The tractor had no problems going through the grass.
To be safe I later blew out the radiator and trans cooler. Then I heard the noise again. Off and on.
I started poking around and when I opened the little tool box under the fuel tank, guess what? Bumble bees! The box was full of nesting material from something, probably mice, and it was now full of bees! Ha ha! So glad I didn't get out in the middle of the field and have them get really upset and take it out on me!
