The only attachment i have that i am not too pleased with is the roto tiller. it does an excellent job if you don't have many stone, which i have lots of medium sized stone. The stone get lodged between the tines and housing of the tiller , it is not hard to get them out, just turn the switch for the tiller off and they often will fall out or put tiller on the ground and move tractor forward or backward. The problem is mostly my stony ground not the tiller,however i believe they could have made more clearance between the tines and housing.
there are several attachments i would like to have in addition to what i have, the brush hog mower, post hole digger and the snow blade , i'm just not sure the my use of these would justify the cost, no snow the last several years here in w. pa., i don't dig many post holes, and as for the brush hog i'll use my big tractor or my gravely.
the power trac is really a nice tractor and fun to operate and i have had no problems with it in 2 years and 267 hours.
