Please excuse my ignorance in the commentary. The rear pump supplies pressure for the bucket and the loader and primes the two hydrostic pumps for the left and right side drives. The hydrostatic pumps are variable displacement pumps that use a swash plate to control the amount and direction of fluid flow. I was able to buy just the shaft for the front pump and the drive plate and a couple of seals and gaskets for around $300.00 and complete the repair.
