Yes,use a length of chain instead of toplink[heavier chain,with connectors of some kind on each end that your pins that hold top link on go through],set it up the height you want to cut and leave a little slack in chain,won't be able to pick it up as far,and be aware of the fact that if front of hog catches ground or a stump or something rear wheel could come up,so I 'd just do this on fairly known ground with height set up to about 6 inches or so. Just try it and play with it a little and you'll know why I've been cutting like that for 7-8 years now.
You don't even need a top link except to raise it.
