I have a 445 with a quick hitch cylinder leak. It has a lift cylinder and an angle cylinder. Part number stamped on the lift cylinder is AM119905. I think this part number is obsolete and replaced by AM147210. I cannot see the part numbers on the angle cylinder but based on internet research it should be part BM17650.

The price for a new lift cylinder is about $400 and a new angle cylinder is about $200.

The only difference I can see in these is how one of the fittings connects to the cylinder with an elbow rather than straight. I would like to save $200 if I can.

Question: Will a replacement angle cylinder work as a lift cylinder?

WG, I can't find specs on BM17650 as far as bore, stroke, pin sizes, etc. Your $200 cylinder may work, or not!

The info I found for the angling cylinder is JD # AUC13259 or AM31362. The AM31362 is the same as the AM119905, so no $$ savings there! Try to verify the BM17650 is the correct part number. If you have the tools to grind the weld, repairing the cylinder is the cheapest way to go. Bob

Angle and lift are both same. $400 for just the cylinder? And $200 for the whole kit? Interesting.

Thanks all. I understand the different part numbers relative to the cylinder kit with hoses compared to the lone cylinder. My concern was if the angle and lift cylinders were actually different. Based on the replies and what I see on the internet parts lists the cylinders appear to be the same. Or at least I can't confirm they are different.

Additionally, I tried to compare part numbers from the original cylinders on the quick hitch. I also looked at the chute cylinder for the 47" two stage blower that I have. The quick hitch lift cylinder and the chute cylinder are the same, but the angle cylinder did not have a part number on it.

Oh well....I am ordering the BM17650 kit. I expect it will fit the bill for the replacement quick hitch lift cylinder. It's not a bad idea to replace the hoses, too. I will let you know results in coming weeks if anyone is interested.

Rockshaft/Deck lifting cylinder too long. Quick hitch cylinder 8 inch length, rockshaft/deck cylinder 9 inches.

What is a rockshaft/deck cylinder? You are using different terminology than previously referenced. Please clarify. Thanks.

I have always thought the deck lifting cylinder was very similar and could be retrofitted since they are commonly available used and cheap.

I replied to randyandrewsber mentioning rockshaft/deck cylinder. The cylinder that lifts the mower deck, nothing to do with quick hitch.

WG, On the rear of your tractor is a shaft that goes from one side of the tractor to the other. This is called the rockshaft. It'll also have arms on it that attach to a mower deck if installed. The rockshaft is actuated by a hydraulic cylinder and is referred to as the rockshaft/deck cylinder. It's similar in appearance...a cylinder with a rod!... but may be physically different and not interchangeable with other cylinders. Bob
