We have 5 815 3 high 2 low 4 915 1 high 3 low
kicked a 815 with a 407 in the head for the motor on another 815 didn't cut 50 acres straw walker crank broke threw straw walkers out back
took 407 off back on the one it came on and patched back together to finish
Then came the 915 herd
We never ran the 915 high it got killed for the dt407 , the low profile ones we had did ok as the hedge row was filled with parts .
915s made a great brome seed machine as the didnt have much air to throw it out the back
