I know steel tracks would improve lift capacity. My question is how much? I have a Case 60xt with a ROC of 1800. I want to get mclaren steel/rubber tracks for traction and improved lift capacity. I really like the Case machine and would upgrade to a 440 but I really dont use the machine enough to justify the extra $$$. If the tracks would allow me to lift about 400lbs more that would be perfect. Is that reasonable?
