prd I have rebuilt both, a 5XL and a Stallion, and from memory both move the deck to engage the cutter, very simple easy setup. I believe the 5XL is a better machine because of the heel/toe drive. I had to fit a disc brake to the Stallion because if you used it on hilly ground and you had to stop you were in big trouble because they were only fitted with a park brake that could only engage when it was stationary. Move the gear lever out of forward/reverse and they become a billy cart, straight down the hill. Not one of Theos better designs
