I also did not do well with the fork Bluey linked, when there was bedding in the stall. Straw or sawdust. It has since been used as a mulch fork in the garden. Does a great job moving woody mulch.
My question is what kind of bedding are you using?
I found that with straw, the 10 tine metal fork from TSC worked well. Not terribly heavy, close tines held onto the load. It would get under very wet spots and lift the whole spot without losing any. Also good pulling sawdust from the tractor bucket directly into a stall. No bendy tines or snapping them off like plastic pulling against weight of the sawdust. I can avoid wheelbarrow use that way. One less step.
For cleaning any woody bedding products, the plastic wins. I like the lighter weight, stall after stall. Easier on me. I have gone to the Wave fork with replaceable tines. They are guaranteed and will replace tines. I called them and got 2 new tines sent because I disliked the basket edges on the outside. I had to completely turn the fork over to completely empty it. Too much work for me, every scoop, so I changed out the basket tines (2) for plain tines. Easy to change tines and I really like it now. Easy to just tip fork head a little to totally empty into the spreader. I think mine is about 4? years old now. No broken tines, though they are a bit shorter from wear on the cement floors. I figure the slightly higher cost but no breaking, is less than yearly replacement of broken, cheaper fork heads. Now if only I could get husband to use this fork! He has broken 4 plastic fork heads so far this year. Being retired now, he is doing more stalls these days. At $9 a replacement head, that adds up.
A tip on the Wave fork, is to zip-tie/ cable-tie the two outside tines to the next tine. Tines are bendy sideways if not secured to the next one, come out of the socket, which quickly fills with dirty bedding so it can’t get locked together again. I find the cable tie keeps them in place, no bending. Might be how I use the fork, scraping and sliding along the wall to get dirty bedding into the aisle.
The handles are nice too, light, with a mushroom shape cap that is comfortable to push on.
