I’ve used this four times and it’s worked very well. Just wanted to leave a couple comments that might assist you if you purchase this. Use gloves when assembling. The spikes are very sharp from the factory and you will be handling them as well as handling other parts while in close proximity to the spikes. Lay out your parts and follow the instructions. The instructions are complete and there is an accurate parts diagram. I had no issues with assembly. If you have to raise and lower the spikes frequently due to tight turns or having to cross hard surfaces, consider a modification I made. I drilled a hole in the handle that raised and lowers the spikes, attached a rope through the hole, then attached the rope to the back of the mower. This way I can reach back and raise the spikes without having to get off the mower every time. After several uses, the spikes may become blunt due to hitting rocks etc. The most efficient way for me to sharpen them was using an impact driver to remove the nut that secures each spike, then sharpen the spikes with a grinder. Hope this helps.

Left wheel wobbles. Cannot be straightened. Shaft weld broke and it’s sitting in yard totally unusable. Got one season out of it. Very cheap material. Not tough at all. Cheap.
