I couldn't be further removed from expertise myself. Just watched a BUNCH of youtube vids and more flexibility with smaller machines was discussed. The podcaster runs a landscaping company. A smaller machine in back and side yards would be advantageous. Sometimes a couple inches makes all the difference (that's what she said).
My 2012 Tak is only ~74" wide. Very unusual in the 12,000 lb. class of skid steers. Due to DEF etc they are now up to ~13,000 lbs. Bobcats T870 may have a larger frame than others but its weight is ~ the same as the biggest by Cat, ASV, Tak, Deere and others.
I consider Bobcat at times. So many for sale and so many Bobcat specific attachments. No adapter needed. They had a good rep prior to the Doosan purchase. Their reliability rep has suffered. I think mostly due to issues with emission related technology.
When did DEF become a requirement on engines over 74hp?
