I have 2 hand control hydro's, and White 1655 and a Cub 1512. The cub has a deck as my main mower. It does take some quick hand work at times to control ground speed, deck lift/lower and steer all at the same time. Takes a lot of getting used to. I take it that lever on the right rear fender is the hydro control. I can see where that would be a problem due to the distance from the steering wheel. The conversion could probably be done using different home built linkage under the tractor. Be quit a winter project for sure.
