Are there any videos of the actual building process??
No, just this and a 2 year update video. The plans are very detailed with instructions and i have a ton of construction pics on file.
do they have plans for a cub cadet 782 do you know?
same loader, just change from the john Deere hook and pin mounting setup to the cub cadet hook and pin mounting setup. the cub cadet has only 2 GPM @700 psi for onboard hydraulics compared to the JD317's 3 GPM @ 850 psi, so it may be a little slower.
@@p.f.engineering9508 ok great thanks, I will probably purchase a separate pump as the 782 pump on mine has only a single lever.
the 3 to 6 GPM / .38 Cu. In. / rev. single stage gear pump would be a good choice to run this loader at 1/2 throttle or so. 3 GPM at 1800 rpm, 6 GPM at 3600 rpm. the plans have a list of online suppliers and bill of materials for all the compact hydraulic parts from vendors i have used in the past and can personally recommend.

Very cool setup.
copied from my website : pf-engineering.com/dump-trailer-plans "The bed-lift mechanism on this trailer is our unique hybrid design that combines the best aspects of a straight-cylinder lift with the benefits of a scissor lift, giving you more extension with a shorter cylinder, plus increased power during the most difficult part of the lift cycle - the start. If you look closely at the first video of our prototype (Oct. 15, 2021), the lower scissor brackets remain stationary, resting on the cross member, for the first 12" of the lift. This allows the cylinders to progress from their initial 30-degree lift-angle to 50 degrees before the scissor brackets begin lifting off the frame’s cross member. This takes all the stress off the scissor-pivot linkages during the most stressful part of the lift, and it gives the cylinders a good positive angle to work with right from the start. It also allows us to use fairly low hydraulic pressure with small bore (2.5") hydraulic cylinders, which increases the longevity of the hydraulic system and parts. The old garden tractor I used in the videos to lift 3000 lbs of stone only produces 800 psi, the maximum being at 2 GPM." that said, the conventional scissor lift is at its weakest point at the moment of inertia, or the very start of the lift. so just when you need the most lift power available, the conventional scissor lift falls short. designers have overcome this weakness by using huge bore hydraulic cylinders running high pressure - and it works - but you can also make a brick fly if you strap a large enough jet engine to it. my goal was to use low pressure, low gpm and be able to lift 3000 lbs from my garden tractor's hydraulics. ~ Paul
What are the benefits to this style lift compared to a more conventional scissor lift. Yours looks like the scissors just balance the load instead of giving mechanical advantage.
mechanical advantage comes from the angle of the cylinder(s) at the moment of inertia. a positive angle on the cylinder provides more power when you need it the most.
Would like to see an update video, see how it’s holding up after some use.
Do you have a video you building it step by step?
No, the step by step instructions that come with the plans take care of that.
Visit my site www.pf-engineering.com
@@p.f.engineering9508 Do you do custom changes to the plans for people who want modifications? It would be nice if you had a video on all the features of the trailer and closer up pictures looking at it from different angles.
@@KrazyKajun602 no
I just ordered the designs for the 3 pin loader. Do you think I could mount a universal 3point quick adapter in place of the bucket for multi-use?
Y'all are my heroes. Seriously.
Guido, it mounts just like any other front mounted implement on these John Deere tractors with a 5/8" rod that mates into the two bottom hooks on the tractor frame, then you attach the hydraulic hoses and boom down to tilt the upright towers of the loader toward the tractor. when this happens the two spring pins snap into the upper two holes on the tractor frame and you're done. if your tractor doesn't have front implement mounts like this, you can just extend the front frame with some 1/4" plate steel for bolting the mini payloader to or copy the bottom hook and top spring pin idea from the john Deere tractor implements. it's not hard to do. some people wonder how you get the hood open with the loader on the tractor. to do this you just release the top two spring pins on the loader mount, unpin the diagonal braces at the upright towers and boom up to tilt the towers forward a little, then you can open the hood fully without taking off the loader. when you're done you can just boom down and tilt the towers back so the spring pins can snap back in. if you want to keep the mower deck on along with the loader or you have other front mount implements you want to swap out, this loader is the easiest option there is for having a loader on your tractor. PF
Sweet loader. How easy does it mount/dismount?
i made it so it hooks onto the lower implement attachment pins and when you tilt the main frame back toward the grille there is a spring pin that snaps into the JD factory implement mounting hole on the top. then just add the diagonal braces back to your foot rest area, plug in and go.

this lift was with 320 lbs of cast iron weights. the tractor can only put out 800 psi hydraulic pressure, so if your machine (or hydraulic pump) can manage more hydraulic pressure you can lift more weight but i think 320 to 350 is plenty for this tractor. ~ Paul www.pf-engineering.com
How much was the lift load
it was 350 lbs of cast iron weights.
@@p.f.engineering9508 how much weight in a bucket full of say dirt or gravel? Will a bucket full be too much or should the bucket be downsized for a 318.
@@The613MC if you want to do full buckets of sand and gravel i would suggest building my conventional mid mount loader plan that has two hydraulic cylinders per movement. that loader is built heavier and can take higher loads. the pin-on loader was designed for light duty work like mulch and other lighter loads.
Great job . PF has some good plans .
thanks tim! it actually fit very well to my surprise. i made some new motor mounts that lowered the engine a little bit in order to keep the output shaft and the front PTO in their original home positions but other than that it went very smoothly. ~ Paul @ P.F. Engineering www.pf-engineering.com
David, if the deck height is adjusted to its highest cutting position, it will not move when you operate the loader. I didn't do this in the video because i wanted to keep my cut height and not have to change it. Davis, thanks! and yes, those bump stops along with the diagonal braces really help channel the stress to the frame and not wear out the front implement mounting points. you've probably seen those other videos of front mount pin on loaders with the towers moving back and forth during operation, and shaking your head like me. ~Paul @ P.F. Engineering www.pf-engineering.com
I'm not sure what the add-on hydraulic pump for the 200 series puts out for GPM and pressure, but for the Mini Payloader, if you can match the 3 GPM at 800 psi of the 300 series JD, you'll be fine. if you want to upgrade your 214's belt driven pump, look for something that puts out 3 GPM at 1800 psi and 6 GPM at 3600 rpm. another spec would be that it will pump out .37 cubic inch of oil per revolution. ~ Paul @ P.F. Engineering www.pf-engineering.com
TruStudio, when the plans come out, you'll be able to build your own dump insert for a lot less than $2K! the hybrid lift is a modular design, so you'll likely have to setup two brackets and a cylinder on each side of your drive shaft. not a huge deal. the most expensive part will be the electric/hydraulic pump unless you can setup a drive pulley somewhere on your engine for belt driving a pump, something like the older snowplows had. ~ Paul @ P.F. Engineering www.pf-engineering.com
Hi, can you make a hydraulic dump insert for my 6' bed pickup truck? Can pay $2,000. We're located in NY
the nice thing about a 430 is the additional weight (almost 1200 lbs) and the onboard hydraulics put out 4.65 GPM at 1000 psi., way better than the 317 in my experiment.
Same as Alan over here -- Nicely done, Paul! I can't wait to add it to my 430 / mini payloader combo. Will be a fine addition to the collection! :)
👍
Great build. I agree with one of the other comments for only using 2 cylinders for weight and speed. Plus I love the bump stops built in for when pushing so it transfers the load to the frame not the cylinders. And the scissor action for the bucket to keep it level without extra operator input.
Great video Paul. That trailer would be a good addition to my collection.👍
Nice work Paul! This will be a great addition to my 430 and mini payloader combo.
Fantastic work! It looks well sized for the garden tractors!
Looks great Paul! I'm looking forward to the plans.
Did a nice job ,I like the 2 cylinders less weight.........
this one is 100 lbs lighter than the conventional loader plans i sell, so it should be easier on the front end on lighter tractors.
I've been looking at your design. Thinking of getting the plans. I have a 214 with hydraulics for deck lift and front and rear implements. I know it will fit. Wondering if I added this to the pump if it would be enough or should I add separate hydraulic pump? If so what size would I need? I know i would have to add bigger resivour and separate spools.
Clearly I wasn't paying attention to see that these plans were coming. I ordered the regular front-end loader plans, which should arrive soon, although these would be more appropriate for my use case. Any chance for a trade out or do I need to make another order when they come out?
great job and looking forward to the plans coming out. I have been looking for a project for a while and this will be great. One question I see when you raise and lower the front boom the deck moved as well. is there a way to separate them?
the mower deck height adjustment can be set to full cut height, then it will stay up and not move around when you operate the loader. not a huge deal.
You can add a lock out valve to the deck lift to isolate it.
nice!
Great project, nicely done!
Congratulations ! You put a ton of work into that.
