i just bought my first new tractor ck27 it has the kl130 quick attach bucket also , im noticing its very weak when i push into a pile of 57wash stone as far as lifting and rolling back i have to back out a bit which is pethetic, after using a ford 1720 25hp with a bushhog loader which didnt even grunt as doing the same task, is there anything that can be done? i love the tractor except for this and if i had known this i would have probaly not of bought it really disapointing , it also does the same with dirt
