D6D is an updated D6C with a few more horses while the D5 was developed from the D6B and is a much lighter machine, very popular with farmers. Personally, I wouldn't let dropping the belly guards put me off, that branch guard fitted plus a pull lift will make it quite easy to get the front one off, I doubt if you will need to remove the rear one to work on the forward section of the cooler lines.
i have owned both of the machines that you mention. and as a farm dozer and if you are happy with and have a good dependable d6c then would just keep what i have. now on the other hand a step up to a D7 might be different. especially if your d6c is a good one then you could gain some capitol towards a d7 purchase.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
