Motorised Forecart for Horses: Progress Report 90% Complete!

This project has been a 5 year back-burner project that I've finally prioritised. Tubular steel chassis, full circle steering, GMC 366 Tall Deck V8 engine with 5 speed New Process trans to run PTO and Edbro hydraulic pump supplying 3 control valves on the manifold to run 2 remote cylinders and a 3 point hitch assembly to be installed at a future date. Engine has 250 hp so I don't think it will have any issues cutting and baling hay or combining. I even hope to use it on the snowblower as I have a V drive ahead snowblower, and the bushhog, once I get the 3 point hitch made. Original plan was to install a 4 cylinder Wisconsin but it needs a complete teardown and overhaul. This engine out of a 79 GMC dump truck with trans and hyd pump cost me $500. I installed a new fuel pump, new carb, plugs, wires, and alternator, a rad from a wrecker, and an Amazon 5 gal fuel tank for a generator. Pretty sure the engine has the berries to run a forage harvester, or be stationary power on a sawmill or a silo filler, if I needed it to.
Designed for use with 4 horses under normal field operations. Has mechanical rear brakes. I may upgrade to hydraulic rear brakes in future but I'll see how these do for a year or so.
