Hi As you can see I am new to the site . I am chief of a vol. fire dept, in Delaware , We have a b20 Kubota tl420 loader with a bt750 hoe , We use it around our station for snow removal and odd end job We have been having a problem with the hydraulics for a long time now, If you are pushing snow and it starts bogging down you can bottom out the loader valve and it seems like it doubles the power. Also if you are going up a hill on the road and you move the valve it will increase the speed a lot. We are a small fire dept so we don't have the funds to take it to Kubota and have it repaired Thatns For all your Help Billy
