that was just a google image ...  are you looking for stock dr blades , because i think gator blades might ?? have a high lift mulcher set ... and i say MIGHT ....  (it's listed here some place just search the word > gator < )  ... my guess is they will not be cheep! but very effective ... i have a set on my itty bitty snapper ... lt15/38 ... and i have black walnuts ... too many to gather ... lol

Swisher 44 rough cutreview

can you post pics of the old blades ... and usually (not always) the part number is sometimes stamped in the blades themselves ...

A.Thank you for your question. This blade kit is for the TB1 models of Tow Behind Field and Brush Mower. It would not work with our current models of Tow Behind Field and Brush Mowers.

okay, just a stab ... in the dark ... how about these ? https://www.drpower.com/Power-Equipment/Lawn-Mowers/Tow-Behind-Mowers/Accessories/Blade-Kit/p/000000000000371101

i get what you talking about, no disk .... that would be the same setup  as a heavy hinge blade setup (none stump jumper model)  on a multi blade (timed gear box) brush hog ... kinda of like turbo twisters setup ... uses a blade like this ? or close ?

Interesting. I have a DR tow behind.  Its configuration is much like your Swisher.   It cuts anything, a beast too, but the ATV and mower wheels lay the grass down, and the mower doesn't have "lift".  Result is going over it at least twice, and/or in the opposite direction.  Looks like DR no longer makes this configuration, as your and mine were made.

Q.Is this the blade kit for the DR Field and Brush Mower Pro Max 52T? Can I order extra bolts and nuts? Will the heavy duty blade kit also fit/ work on my Pro Max 52T?

The thicker the better for this mower. It will cut dense grass/hay, when I do I lower it till it's pretty well dragging on the ground and have found when doing hay/grass to go as fast as the terrain will allow. I average 10-12 km/hr doing fields that are just dense grass. Its arguable it's hard on the bike towing it going that fast lol, but I've been doing my 20 acres cleared land for 10 plus years now and she never skipped a beat. Basiclly, 1st gear for the heavy stuff, 2nd for hay fields. The land I have is on the base/side of a mountain, parts of it is very steep(too steep for tractor) and although the mower is only splash lubrication it also has never skipped a beat. I believe that depending on where you live and what kind of grass it is makes a big difference. My bike will lay the fields over a bit but they spring back up on there own  lol. Probably just the type of vegetation I would guess.

Well after 2 years of being disassembled, I put my mower back together and  put it to work. Seems to be working well. Pics arent great but I tried to get a b4 and after sorta dynamic. These mowers are a beast if anyone is considering buying one

No, just standard blades.  Because they pivot between the drive and the end of the blade, to swing free of a heavy obstacle, I suspect that is why they don't want too much lift.  Hope that makes sense.
