Custom 3 pt. Hitch, Custom Detachable Loader w/ quick-attach bucket, HD/reinforced frame/axle/tires
I just finished up the loader on my 2004? 4020PS. The loader itself detaches in 5 minutes or less. It has a quick-attach bucket system based on the system used by Toro Dingos. I currently have a bucket and a set of homemade forks. I'm looking for commercial forks now.

I started by fabricating a new HD front axle w/ Timken bearing hubs, and moving the tie rod to behind the axle. The front tires are HD 6 ply hi-flotation. Next I reinforced the frame, adding 4"X2"X1/4" angle iron to the frame rails, reinforced the frame where it meets the transaxle, and added triangular struts running up from the sleeve-hitch mounts to the loader crossmember. Bucket tested to 1000lbs, will definitely do more. Greatly improved parking brake, just push the "special" pedal to set the brake.

For hydraulics I chose to machine a power beyond port into the factory Travel Control Valve and fabricate a custom power beyond sleeve integrated into a #8 SAE swivel. Then to boost hydro pressure to the PB port, it was necessary to block the factory "accessory lift" pressure relief, and install pressure relief into both of the "accessory lift" work ports at a point after they leave the TCV. For that purpose I created a custom dual-port pressure relief valve. So the deck and 3-pt lifts still have pressure relief at about 400PSI, while the power beyond port delivers about 2300 psi to the loader valve.

To detach the loader, you suspend the loader's back end from a (purpose built steel) sawhorse, pull the two 1" pins in each vertical tower, and reroute two hydraulic quick-disconnects. Then simply back away.

I used a thin/low profile crossmember, so the mower deck still has "full" travel. (90% plus of original). The new front axle has slightly improved turning radius vs. factory. Front Snap-fast attachments still function as normal. Operator ingress/egress is very good from either side, loader installed or not.

Rear tires are loaded with RV Antifreeze, (118lbs each) and the bucket will pick up 1000lbs with no addtional rear counterweight. (But the rear tires do become very light with that bucket weight) For full bucket capabiltiy, simply pick up a single 330 lb concrete counterweight with the 3 pt. hitch.

For slick/muddy work, 2-link tire chains are required. It's not quite as good as ag-1's but ag's are poor for mowing, so it's a necessary tradeoff.

My goal was to learn from every commercial and private loader build out there and create the very best loader possible while keeping the tractor's factory capabilites fully intact. I also documented the process along the way. I'd like to think that I achieved my goal, though I couldn't have done it without studying and learning from both Case's original commercial loader and the many shop-built loader projects that have come before.
