Sideways, not that I know of. There is a transport lock to keep the boom and dipper upright when roading or using loader bucket. When”folded“ for transport I dont remember the hoe being wider than the rear tires.
If I remember right, the lock Is a pedal to the right of the right swing pedal. The lock can be engaged by manipulating the hoe and loader without slamming the hoe into the lock position. Get the hoe as close as possible into the boom lock using the stick and bucket, then lower/curl the loader bucket (raising front end) to finish locking in.
