Have a ZTHD 52” took the stock blades off at 25 hrs, put on some Oregon 396-806 g6 gator, cut well but don’t seem to discharge the clipping as well , 5 hrs? Also on in gage really ruff , I know heavier blade, and wider, but took them off and installed the gravely back on ,seems to cut as well and also will put the clipping out a lot better, thinking I’ll put the gators back on the mulch in winter, anyway do you guys have any suggestions for better blades than the stock gravely? That cut and distribute the grass any better?
Thanks
 
Gator blades are not meant to bag or be any type of high or far discharging of the clippings. They are meant to mulch only. Mulching means weak lift or suction power. Did you notice the voids on the back side of each cutting edge? Those are there to reduce lift.

What you want are high lift blades. Those sling out far and wide. Also make a better cut as they pull the grass up stronger then cut leaving a better cut.

The Gator G6 are 3" wide and 1/4" thick. So, they are heavier than the OEM blades. Your engine may not have enough horsepower to handle them.
You should check your engine's RPMs. You should have 3,600 RPMs with no load and wide open throttle. That means without the PTO engaged.
 
Here's a blade that will give you a good cut. You will need 1/4" blade spacers between the blades and spindles. Rotary #3404.

Now for a Gator style blade, there's the Rotary # 13016. These blades DO NOT require spacers.
Both are 2 1/2" wide.
Go here to see both.

If you want good discharge, the #3404 are best. This will be the blade to use during the growing season.
When you want to chop up leaves or do your first spring mow, the #13016 will be the ones to go with.
Most Outdoor Power Equipment dealers should have the spacers. They are 1/4" thick x 1" OD x 5/8" ID.

I own a commercial Gravely and have experimented with several blade brands and styles. My recommendations are based on experience. The high lift blades are going to give the best cut and discharge. The OEM Gravely blades do a pretty good job. I use them in my rotation.
However, using the spacers with the #3404 will give you the same deck volume as using the OEM blades. The spacers allow you to use the same deck height settings as the OEM blades. The spacers take up for the offset of the OEM blades.
What types of grass are you cutting?
