sorry to hear on loss of your house. your MF135 is a great tractor, i had the earlier generation 35 TO for many years. in addition to the above advice, periodically check radiator for debris buildup & overheating. think your model is better protected on that than mine was. also, assume your B/H has a "stump jumper" installed underneath on the output shaft, almost a necessity. if you do initial hogging yourself, cut high on 1st pass, go in low range & be patient. & when servicing blades, etc, block up the hog before crawling underneath, rather than just relying on hydraulics. personally, i prefer to remove blades for sharpening (impact wrench almost a must) rather than wrestling around with a grinder a few inches from your face underneath. best of luck on your house plans, maybe post some pics on it's progress! btw if you chain saw some larger saplings, make it a ground level cut! otherwise those stubs will surely spike into your tires, been there before..
