I'm looking to get into vegetable farming and am considering getting a couple of 25hp tractors to do it. There are a lot more options on the market than I expected and I'm not sure which model(s) would work best for me. I plan on having beds that are 36" wide with 18" pathways in between and I want to be able to straddle the beds, so tread width is very important for me. The biggest task for them will be wagon pulling, but I also plan to use them for a 36" tiller, potato digger, flail mower for maintaining fence lines, running a PTO generator, and maybe a wood splitter. I don't need or want a cab for this. I may get a loader for one of them for odd jobs, where a small machine comes in handy. I generally prefer larger displacement, lower rpm engines for longevity and heavier weight machines. I plan for both to be hydrostat transmissions and I want them to be easy to operate for inexperienced tractor drivers.
I've got three models on my short list right now: the Mahindra 1626 HST, the Kioti CK2610 HST, and the Branson 2515H. Kioti lists the front and rear tread width for their tractor on the spec sheet, but Mahindra and Branson don't. I can more or less figure it for the rear axle by subtracting a tire width from the overall width, but the front tread width is a mystery. Does anyone know the front tread widths for those machines? Do any of these models have electronic engine management or are they still mechanical injection? I like to keep it simple.
I'm not at all concerned about putting spacers on the rear axles to widen them out, but I'm somewhat hesitant to try that on the front for fear of messing up the steering radius/geometry and exposing the king pin to potential rock hits. Does anyone have experience with front axle spacers who can educate me on this? I'd appreciate any help you can give me or experience you can share with me about this.
