Garden carts have load capacities that vary from 200 to 1500 pounds. However, selecting a heavy duty garden cart that can hold up to 1000 pounds just because you need such a device might not be a good idea, especially if you do not have the strength to operate it.
Instead, it might be a better decision to invest in a small garden cart that you can use as intended. For yard cleaning tasks, it is best to get a model that has a capacity of around 200 pounds.
If you want a cart that works for crop harvesting and other gardening jobs such as carrying fertilizer, compost, or mulch, you should consider getting a cart that has a bigger capacity, provided that you can use it.
When it comes to handling heavy-duty tasks such as carrying lumber, or construction materials, a unit that can handle more than 1000 pounds and that can be towed to a truck or ATV should suit you perfectly.
