I have switched from small square bales to 4 X 5 round bales. Can no longer throw the small bales and most of the help has all left the nest. All part of the "aging" process I guess. I only have one loader for moving and stacking the bales and usually am working alone. Main stackyard is on the farm and close to the fields - less than quarter mile away. Only time travel on the county road would be necessary is if I sell excess hay to the neighbor a mile up the road. My fields are mostly flat with a few small swales. Road between the fields and stackyard crosses down through a small creek drainage and back out again. Looking at options for efficent moving of the bales from field to the stackyard. Will probably be 400 bales or less a year. Don't need the high production or cost of a self loading round bale hauler. Was considering a smaller bumper pull self-unloading hay trailer (don't have a hitch for goose neck trailer). Nobody around here uses these types of hay trailers. Any of you have any experience with them? How stable are they on shallow slopes or crossing a small drainage? When you unload them, how well do the bales line up or do they roll all over? If loaded from the rear of the trailer with a bale spear, can you push 6 or 8 bales clear to the front of the trailer without pushing the trailer along? If pulling up a slope on rough ground, will the bales slide back (or off!) the back of the trailer? If pulling the trailer with a 3/4 ton pickup or tractor, will it be a rodeo without trailer brakes? Your experiences? Makes of such hay trailers you are familiar with?
