Good job! Unfortunately I have the 2015 HD 44 model 991090 and have attempted to put on several 1/2 x 67 belts and they are too short. I have discovered the fastest and easier way to put the belt on is to disconnect the pro hardware as you showed and remove the right side fan/pulley and tension pulleys. 1. You can feed the belt through the right side fan hole between the tension pulley pivot bolt and tension pulley to the open area behind the left side fan and easily wrapped around fan and pulley. 2. Wrap belt around PTO pulley and use a medium binder clip to keep the belt from dropping off the pulley. 3. You can then install the belt on the right side pulley (last pulley as per Gravely instructions). Mine takes a 67.47" or a 4L68 (67.75") because the true 67" belts are too short and can't even be forced on. Hope this helps someone with the same model and year.
