I found some time to finsh getting the bucket grab hooks in place yesterday. I'm not used to welding such thick material. I don't think I'll have anything to worry about as it seems quite solid.

Next major undertaking... attaching a 7'6" Western plow I've had sitting around for years to the front of the SA324.

I have stared at the plow and tractor for a total of three evenings and I finally came up with a plan using stuff I had laying around.

Strongly considering the size and weight of the plow, I've decided to build a subframe on the front of the tractor. The previous owners of my property must have had an Allis-Chalmers 5220 or 5230 because they left the brand new ROPS in the barn. Lucky me! The beefy ROPS has become the basis for the subframe. I don't think I could have asked for a more perfect thing to start with.

The subframe will (tentatively) attach at the rear mid-mount mower lift point, the front mid-mount mower lift point (rear of the front-end loader mounts), and the front "bumper". The primary issue that the hacked-up ROPS is going to solve is clearing the front axle with the axle at full articulation and steering at full lock. The mock-ups I've done make it seem VERY promising.

I've also mulled over how to handle the plow lift mechanism on the tractor side. Some more staring lead me to the leftover mount of the repurposed ROPS. It is going to become the new permanent front bumper on the tractor. I drilled some holes and did a quick test fit. I lifted the front of the tractor with the loader and check for clearance between the tires and bumper. Plenty of room and it looks like some monster off-road bumper you'd find on a Jeep!

The "bumper" will be fitted with two upright arms to support the plow's lift arm. It will ultimately look sort of like a brush guard and function as one since the original will have to be removed. The plow lift arm and plow lift cylinder will pin-on so they can be removed when the plow is not attached.

The lift cylinder that was on the plow had some pitting/peeling on the cylinder itself, so I ordered a replacement. I decided to go with a 1.5" x 10" (instead of the stock 8" stroke) so that the lower mount worked out a little better. I don't think I'll actually need the extra lift height unless I'm making some big snow mounds.

I also got the brush guard cross bar installed.

The entire lift mechanism pins on and can be installed/removed in a matter of minutes.

Due to the extended lift height, I had to notch out the back of the lift arm to make room for the cylinder.

Is the plan to remove the bucket and use those hydraulic lines for the plow?

Yes! The overall idea is to make the plow and components as quick-attach as I possibly can. Using the tractors existing hydraulic system helps make that possible. I'm shooting for < 5 minutes on/off.

All the hydraulic hoses on the plow need replaced anyway, so I'll replace them with lines long enough to run to the existing connections on the tractor.
