I agree on the big feet, I tired making my own and although better than nothing, the OEM feet are much better. I don't remember what I paid for them, but I have not regretted the expenditure.
having said I do not regret the expenditure I still think they should be supplied with every new back hoe, paying $6500 for back hoe, just another Kioti gotcha for $80 or $100 bucks.
