I don't know? but it is recommended by Deere. It is actually very heavy on the rear of the tractor when its heaping full, I can see why I might need them on inclines.The front weights are sexy as ****, but do they really help with mowing?
Hopefully won't have to add on. Actually my shop is 40x63 with 14ft. sidewalls. What you see there is a 26x26 corner of the shop that was built as a toy room with its own overhead and walk-in door. if you look in one of the pics you can see another door leading into the rest of the shop. I keep my truck, skid-loader, sea-doo pwc, and work equipment in there. Also built a set of steps in the shop leading up to the top of the toyroom to store stuff up there as toyroom has an I-joist ceiling. Got plenty of room for now, just need to quit buying stuff!!!!:banghead3You've still got plenty of room--just have to add on to the space!!!:Stop:
