I built this rear bucket for my Wards Garden tractor. Reason for going to rear mount was mostly expense and simplicity. Front loader would have been more work and steel for an awkward frame mounting system. And I would have had to add secondary hydraulic system. I figured a front loader would have cost $1300 - $1500 to build. I have about $450 in the rear loader.
The rear blade is raised by one cylinder powered by the HST. I put quick couplers on the existing spool valve that enabled me to switch from the little existing implement raise/lower cylinder to the rear bucket. The rear loader frame was attached to a modified sleeve hitch bar (2 point attachment to rear axle) and a homemade adjustable top link. The bucket is powered up and down hydraulically and manually dumped via the go-kart disc brake which is activated with truck emergency brake cable connected to an over-center lever.
Overall I was pleased with the outcome and operation but none-the-less the unit has its limitations.
Without powered curl, normal loader operation was modified and a bit cumbersome. I'd have to push/scrape into the pile, go forward, push the bucket flat on the ground, continue to go forward and rock the bucket back (curled) to place the load to the rear of the bucket so I could clear the front portion of the bucket for more material.
Capacity was an issue. The rear loader worked great for turning compost piles, moving leaves and other light to moderate loads. I could pick up a full bucket of soil but the top link was attached to the back of the HST and heavy loads would rotate the HST in its mounts.
Neck strain was the other issue. It takes a lot of looking over the shoulder to operate and this becomes very tiresome after a couple of hours.
The latter was the final straw. The operation shortcoming was awkward but accetable after some practice and the top link attachment could have been modified, but the constant head tweak is the rear loaders biggest downfall.
In the end I'm glad I built it. I solved all the problems by finally breaking down and buying a
BX23 loader/backhoe. Now I have two tractors!
