Wanted,,,Im searching for some lower links that will fit and work with my B21. I bought some after market from ebay,,,and they are soft mild steel and bent.
These parts are shared with a lot of different tractor models:
B1700
B2100
B21
B2320
B2400
B2410
B2920
B7300
B7400
B7410
B7500
B7510
B7800
B26
B2620
B2920
B3000
B3200
B3300
I think it would be what in the pics is refered to the "lower links". Id bought a whole "kit" on line but the pieces are evidently made of mild steel and when I hooked them up and was working a brush hog,,they bent from lifting the mower through out the day.
