I was actually referring to the PTO hp, which is how tractors of that size are typically rated. Keep in mind that 61 drawbar hp may not sound like a lot but this is a heavy tractor and weight equals traction which is something most utility tractors are short on. I am speaking from experiance with this size tractor, I grew up on a farm and have driven an IH 856 (just a hair larger than your 826) many, many hours. I assure you, if not used carefully, you will damage that box. That being said, having only paid $100 for it you really don't have much to loose so go for it. If you are careful with it and use it for what it is intended you may well be fine. Good luck!
