Allis Chambers are great tractors. We have several.... and loved the old d-17 and d-19's.... have the post driver on one... Have 2 200's that we use one has a loader/spear.... Have the big 7040 that is a huge horse and can hold back the round baler on the hills.... the one old one, is a narrow front end, but most are wide front end like your picture. If they are popular in your area, then you will be able to find places to have any work done....and parts tractors around too. And we have found them to be decent on fuel/gas.... the JD we use is a fuel hog, but the deutz is very easy on fuel.... most of ours are diesel.... but there are a couple that are gas. My little farmall H is gas... all our AC tractors are diesel I think.
Intitally just looking at the d19 to pull a bushhog, disc and lime spreader. I know 85 HP is more than I need but sticking to my motto "when in doubt, double the stout" I think I'll be OK. I already have a bucket and set of forks with my bobcat.
