Kub specs the LA302 FEL for the B7510. The LA352FEL offers about 150lbs more capacity but is only spec'ed for the B7610. The 7510 is near identical to 7610 except engine. Pump capacity is the same for both 7510/7610.
Does anybody know why the LA352 is not 'allowed' on the 7510?
Check the metal thickness on the bucket and the size of the lift arms. Maybe they're thicker (heavier), which will put more than the expected 150 pound load on the tractor. May be a little much. Kubota knows best.
