TC40D hydro pedals still stick down when under heavy load, even after adjusting linkage, lube, etc. Resigned to the fact that I may as well get used to it. While pushing up saplings the other day, I was using a rear blade for a small dozer by backing into saplings. Once, had wheels turned all the way to the left while shoving a pile of brush farther into the woods when left corner of blade snagged a hidden stump. Of course, wheels kept turning after I released rear pedal. By the time I got my foot on foward pedal, engine shut off. After cranking and pulling forward I noticed left side of blade dragging ground. Then I saw why; the lower left lift arm on 3ph was well on the way to becoming a perfect U shape. Now I get to pay NH $175.00 for a new one. Don't know if that includes sliding hitch on end or not [probably not, that would cost another $100.00 ]. Too bad NH won't address a common problem on an otherwise fine tractor. Just wanted to pass on for free experience [ I define experience as no more than a series of mistakes].
