Has anyone used the aeration attachment for the walker? I bought one in fall of 2020 and have just now gotten a chance to use it. It seems to be in great condition but i have been having a issue getting it to attach to my machine. The driveshaft that came on it is a few inches shorter and isnt long enough to attach. i have a 2021 B27, 2020 T27, and 2019 T25. I tried taking the driveshaft off of the decks of the mowers where it attaches to the gearbox and the diameter is about 1/8" too wide on the perfaerator. Does anyone know what driveshaft i would need to get it to work on these newer Walker mowers?
