I am getting ready to replace all the filters on my 853 since I don't know when the previous owner had done them. Machine has 1688 hours. I called Bobcat for example and they want $42.00 for a Hydraulic filter. I see Maintenance Kits on Ebay containing the two air filters, oil filter, two Hydraulic/Hydrostatic filters and Fuel filter for $107. They are either Donaldson or Baldwin Branded. I am not familiar with these brands. Are these brands good to use since the pricing is way better than Bobcat Brand or should I stay with the Bobcat Brand? Thank you Greg
