Hello friends, I just got on a garage sale a Poulan 15HP lawn riding mower and the manufacturer ID# is HDT15542A the serial # 050499C 003131. and has a Tecumseh engine. On the hood it says, Poulan 15Hp/XL/C OHV/42" Cut and has 6 speed. I cannot find any information on the internet and or cross reference this model. All i have found is the 16.5 hp but with Briggs engine. Please help if you have any information, like a manual or a correct model number?
