<font color="orange"> Kubota </font> makes a set of forks in 36 and 42" length. Price for 42" is over $900. Since you have a QA you should be able to get forks that fit a skid steer for less money.
My 42” Bob Cat brand forks were about $700. Any Skid Steer dealer should have forks available for the QA set up. I use the forks almost as much as the bucket. Well worth the money to me.
