I have been using a B7800 with a FEL to move fill and top soil around a tight lake lot to prep for seed. I had 2 flats Saturday and was able to get 1 fixed. The first 1 had a hole in the tube near the rim / bead and had a tube installed. The second 1 was too late in the day to get to the dealer and they were closed today. I tried slime but it didn't work. I'm considering foam filling the fronts but have seen some negatives and don't want to damage the tractor. I only have the weekends to get the work done and I lost a day this weekend because of flats. This tractor is primarily used with the loader and the lot is tight, lots of turns with a full bucket. Please advise.
