I don't have a MMM on my
BX24. I mow a field of _grass_ (not sticks or rocks) with a little bush hog. I don't get there often so the grass is tall and tough.
1st thing that happened was (AFAIKS) grass wrapped the drive shaft and took out the wiring harness. $$$! Got that fixed and went back to finish the job.
Grass wrapped the front pinion shaft and wiped out the seal. Just $$ this time.
I run all 3 Bro-tek plates and a guard I made for the front pinion and u-joint out of 3" ABS. So far so good.
I regularly check for debris accumulation, which seems like a good idea in any case. My mechanic tells me that crap can also accumulate between the rear wheels and transaxle, and take out those seals. He says replacing one of those requires splitting the case. Ugh.
Let's be safe out there...
