"This would be my third.....cant justify"
You are correct, hard to justify 3 of the same tractor.
Look for a Hundred or Thousand Series.
Upgrade, branch out, learn something new.
Get some bonus features - Differential lock, power steering, more HP, more gears (tiller capable) live pto, live hydraulics, remotes, maybe a diesel, more longevity, a better tractor - and still use the same implements you have now.
